Important Safety Instructions:
1. Read and follow all warning notices and instructions marked on the product or included in this Reference
Guide.
2. This product is intended to be used with a three-wire grounding type plug - a plug which has a grounding pin.
This is a safety feature. Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the
grounding type plug by modifying the plug or using an adapter.
Prior to installation, use an outlet tester or a voltmeter to check the AC receptacle for the presence of earth
ground. If the receptacle is not properly grounded, the installation must not continue until a qualified electrician
has corrected the problem. If a three-wire grounding type power source is not available, consult a qualified
electrician to determine another method of grounding the equipment.
3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and
to protect it from overheating, these slots and openings must not be blocked or covered.
4. Do not allow anything to rest on the power cord and do not locate the product where persons could step or walk
on the power cord.
5. Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous
high voltage points or other risks. Refer all servicing to qualified service personnel.
6. Special cables, which may be required by the regulatory inspection authority for the installation site, are the
responsibility of the customer.
7. When installed in the final configuration, the product must comply with the applicable Safety Standards and
regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate
regulatory agencies and inspection authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If
products installed in separate buildings are interconnected, the voltage potential may cause a hazardous
condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if
necessary, implement corrective action prior to interconnecting the products.
9. Electrostatic Discharge (ESD) protection must be used when handling circuit card assemblies and all other
electronic parts covered in this manual.

Reference Guide v3.6

Preface

Introduction
Premisys Communications' Integrated Multiple Access Communications Server
(IMACS) allows you to take advantage of the sophisticated network services available
from long-distance companies, telephone companies, specialized carriers and PTTs. By
using these new services, you can increase the capabilities of your private network and
simultaneously reduce costs. This Reference Guide will help you put the IMACS to
work in your networking environment.
The IMACS takes the place of many network access devices, including:
•

CSUs

•

DSUs

•

Channel banks

•

Drop-and-insert multiplexers

•

Digital cross-connect systems

By taking over the functions of all these network access devices, a single IMACS
system allows linking a wide range of voice and data equipment over the network,
among them:
•

LAN bridges and routers

•

PBXs (analog or digital) and key systems

•

Fax machines

•

Terminals and computers

•

Telephones

•

Modems

•

Video CODECs

How to Use this Reference Guide
This Reference Guide is arranged to assist the technician in unpacking, assembling,
configuring, and running the integrated access system. The Reference Guide is divided
into Sections. Some Sections are further subdivided into Chapters.
Section 1 contains the Preface (this chapter).
Section 2, System Operations, consists of five chapters: System Slot Map, Installation,
Basic Operations, System Operations, and Redundant Operations. Section 2 answers
most “what-goes-where” questions. Other sections give more detailed descriptions of
the procedures involved in configuring and running the IMACS.
The System Slot Map chapter describes the chassis and details the placement of
individual components.

The system offers the choice of three chassis and employs four types of cards. This
chapter specifies the slots in which cards of different types may be installed in the three
chassis.
The chassis options are:
1.

Front-Loading Chassis - Power Supplies on Side: This chassis provides
full functionality for smaller systems that require few options and small
capacity.

2.

Two-Sided Chassis: With front and rear-facing card cages, this chassis
provides maximum system functionality and capacity.

3.

Front-Loading Chassis - Power Supplies on Top: This chassis provides the
same functionality and capacity as the two-sided chassis with front facing
card cages.

The following types of cards may be installed in the chassis:
1.

Common cards (CPU and Interface cards)

2.

User cards (Voice, Data and Alarm cards)

3.

WAN cards (single or dual T1/E1,or HDSL)

4.

Communications Server cards (ADPCM)

All cards slide into slots in the front of the front-loading systems or the front and back
of the two-sided chassis. Rail guides in the top and bottom of the slots align the cards
with the connectors for easy insertion.

Two-Sided Unit
Figure Slot-1 shows the front of the chassis (often called the Network side) with the slot
numbers labeled. Cards inserted from the Network side have plastic face plates with a
handle in the middle and a retaining screw on the bottom of the cards. Figure Slot-2
shows the back of the chassis (often called the User side) with the slot numbers labeled.
Cards inserted from the User Side have metal face plates with handles at the top and
bottom. Those cards have screws on both the top and bottom of the face plates. Push
the cards firmly into the chassis until the face plate touches the chassis. Screw the face
plates to the chassis so the cards cannot come loose accidentally.
The two-sided chassis has an error-free card placement system. Certain card types are
"keyed" to fit only in their own slots. User cards, for instance, will not seat properly in
the CPU Slots (C-1 and C-2). Table Slot-1 describes card placement and should be used
to determine setup arrangements.
Always put blank face plates over any slots you are not using. Blank face plates help
protect the installed cards from contamination, and are an integral part of the air
circulation system that keeps the system cool. Also, the blank face plates are required
for compliance with UL regulations.

Front-Loading Unit
Figures Slot-3 and Slot-4 show the front-loading chassis. Designed to maximize the use
of space, the front loading chassis has a common bus that allows all cards to be placed
in similar slots. The combination slots for this unit are P1-P4 (Communications Server
card slots) and W1-W4 (WAN slots). Together, these slots are sometimes referred to as
slots U1-U8 (when used for voice, data or alarm cards).
Cards have either metal face plates or plastic face plates. Push the cards firmly into the
chassis until the face plate touches the chassis. Screw the face plates to the chassis so
the cards cannot come loose accidentally.
As with the two-sided chassis, the user should always put blank face plates over any
slots you are not using. Blank face plates help protect the installed cards from
contamination and are an integral part of the air circulation system that keeps the
system cool. Also, the blank face plates are required for compliance with UL
regulations.
Table Slot-2 describes card placement and should be used to determine setup
arrangements.

DC Power Supply Fuse
The DC power supply fuse is located on the chassis next to the DC external power
supply connectors on the front or rear panel (depending on chassis model). This fuse is
used to protect any over current on the network voltage (Vn) located on the DC
connector panel. Table Slot-4 lists the part numbers of approved replacement fuses.

Installation

Introduction
The Installation section provides the user with information to unpack and assemble the
Integrated Access Controller. The installation checklist on the next page is provided for
the experienced user as a road map of installation procedures. This chapter will discuss
the unit, power supplies, and different hardware configurations for some of the cards.
The physical installation of the cards that make up the system is discussed in the
Slotmap chapter. Configuration of these cards is presented in later chapters.

Design Plan
The installation should be based upon a thoroughly considered, documented design
plan. Such a plan assures that the necessary components are on hand to implement the
system requirements and that the site can accommodate them.

Site Selection and Preparation
A site survey should be performed to avoid unforeseen problems. A site survey involves
a physical check on key information about a site, including building codes, floor plans,
available power, existing wiring and grounding.
An integrated access device requires a reasonably dust-free operating environment, such
as a computer room or a wiring closet. Do not install the chassis in direct sunlight,
which may increase the unit’s temperature and discolor the chassis. You may mount
the chassis on a wall or in an equipment rack, or place it on a table or other flat surface.
The unit can operate on either AC or DC power when equipped with the proper power
supply. Table Install-2 lists the electrical and environmental requirements.
The mounting brackets (supplied) are required for table top installations to assure
proper airflow in the chassis. The top and bottom of the unit must be clear of any
objects.
When the chassis is installed in a rack, allow a minimum of 2 inches (1.6 cm) space
between the chassis and the equipment above and below the unit for proper ventilation.
Caution: The chassis MUST be installed horizontally for proper ventilation and
cooling effect.
Each customer must provide either space or climate control to assure an ambient
temperature less than approximately 40° C for reliable operations. If heat dissipation is
a problem, increase the space between rack mounted units or install commercially
available “heat baffles” above and below each chassis.
A wide variety of system functions and capacities can be supported by various
combinations of system cards. Table Install-3 lists the specifications for all components
supported by the system in Version 3.6.

Unpacking and Mounting the Chassis
When you receive the system, unpack the boxes and check the chassis and cards for
damage. If any part of the unit is damaged, contact the shipping company to file a
claim. The shipping company representative will also tell you how to submit a claim,
where to send the unit, and give you any special instructions you may need.
Pack the unit in the original packing materials and send it by prepaid freight to the
address you received. If the original packing materials are unavailable, pack the unit in
a sturdy box and surround it with shock-absorbing material.
The front and back of the two-sided unit must be accessible for inserting cards. Voice,
data, WAN, and power cables are also attached to connectors at the rear of the chassis.
The front-loading model of the Integrated Access Controller does not need access to the
back side of the unit. Table Install-4 lists the minimum clearances between the
equipment and the nearest object for rack-mounted, wall-mounted or table-top
installations.

Mounting the Chassis
To mount the chassis to the rack, attach the metal brackets (see Figure Install-5) to the
sides of the chassis with the four 10-32x1/4 screws (brackets and all screws provided in
the installation pack). Four 12-24x1/2 screws are needed to attach the chassis to the
rack. The brackets are reversible to allow mounting in 19- or 23-inch racks (48.2 or
58.4 cm). You can attach the brackets using holes at the front of the chassis, back of
the chassis or near the middle. If you mount the brackets in the middle of the chassis,
you can reduce the amount of space required behind it for cables. However, the front
and the back must be accessible to insert and remove cards.
To attach the unit to the wall, use the template of the hole pattern (provided) and copy
to a backboard. The backboard should be 1/2" to 3/4" construction grade plywood.
Attach the unit with the 4-10x5/8 screws provided. The wall mount position must be
with the power supplies closest to the wall.
If you are placing the unit on a tabletop or other hard surface, it is mandatory to assure
clearance for proper airflow in the chassis. Make sure the chassis is accessible from the
front, and has at least 3/4 inches (2 cm) clearance above the chassis. The metal
brackets (see Figure Install-5) should be attached to provide the additional clearance
needed for attaching cables to the user cards for both the two-sided and front-loading
systems. Attach the brackets to the side of the chassis using the two (t) holes. Place the
plastic abrasion-protective inserts ("feet") in the holes provided near the ends of the
bottom of the bracket.

Power Supply and Ringing Generator System
The power supply and ringing generator system can consist of up to two power supplies,
two AC to DC converters and up to four ringing generators. External -48VDC talk
battery and external ringing generators may be used instead of the internal units. Use
the following guidelines to determine your power supply and ringing generator
requirements.

System Power
The system will always require one of the following power supplies:
Ø AC (8901)
Ø -48VDC (8902)
Ø +24VDC (8907)

Even though the 8907 power supply has specifications listed as negative throughout
this manual, it can be used with positive voltage (+24VDC). Because of the
extremely small number of applications that would require it, the conversion
procedure is not covered in this manual. If you are considering using +24VDC,
please call the customer service number listed in the Preface.
For backup, you may add a second power supply (see Preface for specific UL
requirements when adding a redundant power supply). Redundant power supplies are
not load-sharing.

-48VDC Talk Battery
In addition to the power supplies, a -48 VDC talk battery is required whenever there are
analog voice cards present in the system unless all of those are E&M ports and are used
in Transmission Only (TO) mode, or when Type 1 signaling is used.
A -48VDC power source is also required for use with:
Ø External Alarm card
Ø OCU-DP card
Ø BRI card (to provide sealing current)

If the unit is powered by the AC (8901) supply, either the 8903 Internal 115VAC to
-48VDC or 8905 120/240VAC to -48VDC Converter or an external source will be
required for the -48VDC talk battery. The 8903 AC to DC converter is available only
for 115VAC sources. Use 8905 for 220 VAC locations.

Ringing Generators
Ringing generators are required whenever there are FXS cards in the unit or if any FXO
ports are used in Manual Ringdown (MRD) mode. Ringing voltage may be provided
from an external source or by using the 8906 Ringing Generator. The 8906 requires a
-48VDC source in the system.
Customers having the older 8904 Ringing Generator may still use it.

(10-97)

Page 2-B-9

Installation

Reference Guide v3.6

Warning: The 8904 must never be used in the same system with an 8906 ringing
generator.
Warning: The 8904 and 8906 ringing generators are incompatible with external
ringing devices.
The 8904 provides ringing voltage of 105VAC (nominal) at 20 Hz for 11
simultaneously ringing voice ports, while the 8906 provides ringing voltage of 100VAC
for the same number of ports. With normal call activity, a single ringing generator
might provide all of the power necessary to run the system. In a group where incoming
calls are at a minimum, 30-50 stations could share the same ringing generator. Small
groups with heavy incoming call volumes might require two or more ringing generators.
This card will not “quit” with a heavy load, it will just have weaker and slower ringing
abilities. That condition should alert you to the need for additional equipment.
The compatibility of power sources and ringing generators that can be used together are
summarized in Table Install-5.

US/Europe Jumper
Prior to inserting any cards and powering up the chassis, jumper JP1 on the 891620,
891822/23, and 891920 chassis must be set to US or European configuration. The
jumper is located on the resource card backplane, and is accessible from the chassis
front. The default setting is US. The resource cards must also have the jumper set
consistent with the chassis. See the Slot Map chapter for more detailed information on
this feature.

Chassis Grounding

! ! ! PLEASE READ—IMPORTANT ! ! !

Ø

When using any CPU revision B or C in a six-digit chassis as depicted in
figures Install-6 through Install-9, or in a four-digit chassis as depicted in
figure Install-10 with a voice ringer card installed, the chassis must be
properly grounded to ensure reliable operation.

×

In order to identify which CPU you have, you must either visually look at the white
sticker that has been placed on the back of the mainboard. It indicates the type and
revision of CPU that is being installed. If you do not have revision B or C CPU’s as
stated above, then please disregard this notice.
To ensure proper operation in a chassis with an external power connector like those
shown below, it is crucial that each chassis is properly grounded. This section details
grounding procedures for each type of chassis. This information presumes that the
operator and/or installer has some knowledge of grounding issues. Please refer to Field
Alert Bulletin 108-000004 for a top level grounding tutorial.
The chassis ground is usually connected to the earth ground directly (using the chassis
ground screw) or via the power cord.
) and
In order to minimize electrical potential between grounds, chassis ground (
common signal ground (COM) in the terminal power connector should be connected
with a jumper wire or bridge.
Improper grounding may cause a difference in electrical potential between the chassis
and the terminal equipment, which could damage the cards, the terminal equipment, or
both.

IF YOU ARE UNCLEAR ABOUT STANDARD GROUNDING PROCEDURES,
PLEASE CONSULT WITH YOUR NETWORK ADMINISTRATOR.

same part number. The 8904 and 8906 Ringing Generators cannot be mixed in a
single chassis. Note: Ringing Generator 8904 is a discontinued product. If you are in
need of Technical Assistance, please contact Product Support at (510) 353-7686.
Ensure that the system has a -48VDC power source before installing either of the
modules. You may install up to four (4) ringing generators on the two-sided chassis
depending upon availability of slots. The front-loading system with the power supplies
on the side can have only one ringing generator.
The outputs of all ringing generators are linked together by OR circuits on the ringing
bus. In cases where more than one generator is installed, one must be jumpered as
MASTER and the others must be jumpered as SLAVE. The master ringing generator
will synchronize the ringing signals on the ringing bus. (For more information on
configuring the MASTER/SLAVE jumpers, please see the diagrams of the 8904 and
8906 later in this chapter.)

Reference Guide v3.6

To install the 8904 Ringing Generator:
1.

Be sure that power is off before inserting or removing the 8904
ringing generator.

2.

For the two-sided chassis, remove the panel covering the rear power slots.
You may install the module in any of the five rear slots. For the frontloading chassis, remove the panel covering the front power slots. Install
the module in slot R1 only.

3.

Make sure that jumper W201 is installed if this is the only 8904 ringing
generator in the unit, or if it is the MASTER ringing generator (see Figure
Install-17).

4.

Remove jumper W201 if this is a SLAVE ringing generator. Remove the
jumper by cutting it with wire cutters.

5.

Hold the ringing generator by the metal handle and align the PCB edges
with the slot rail guides in the power supply backplane. Gently push the
module in until it is firmly seated in the backplane connector.

6.

When the supply is installed and power is on, the LED on the rear panel of
the ringing generator should flicker at a rate of 20 times per second. If
this LED is not flickering, something is wrong. Check that the
Master/Slave settings are correct and that the module is firmly seated in
the connector.

5. Replace the panel that covers the rear power slots.

Connecting AC Power
Attach the AC power source to the system at the AC power socket. This socket
accommodates the standard 3-prong molded power cord supplied with the system.
Secure the power cord to the rack or cabinet for strain relief and route it down to the
bottom of the chassis.

Using Amphenol Connectors
Many of the cables used to connect cards in the Integrated Access Controller to wiring
devices use Amphenol connectors at either one or both ends of the cable. The
traditional Amphenol connector placed the connector at a right angle to the cable itself,
(see Figure Install-19) thus preventing the screw at the bottom of the connector from
being properly attached without removing the hood. This type of cable connector is not
recommended for use with this system.

Amphenol

Cable

Figure Install-19. Undesirable Amphenol Connectors
Newly designed cables mount the Amphenol connector at a 25° angle to the cable and
use screws that can be twisted by fingertips to attach the connector from both the top
and the bottom. Other types of cables mount the connector at a 90° angle (see Figure
Install-20). It is suggested that cables of this design be used with the cards in your
system.

Basic Operations

It is very important that you record the configuration information for each card as you
determine its settings. You, or someone servicing the system at a later date, will need
this information to aid in troubleshooting. A simple way to record your configuration is
to photocopy the setting tables in the card sections of this guide and write the
information for your configuration in the column labeled Initial Setting. Store these
pages in a safe place, where they can be available to anyone servicing the system.

Status Screen
A quick way to check activity of the ports of all system cards is to use the Status screen.
Figure Basic-6 shows the Status screen. The lowercase letters that follow card entries
show the status of each port on the cards. The possible values are "s" (Standby), "a"
(Active), "t" (Test), "l" (Loopback) and "r" (Redundant).

Meaning
The card, power supply or ringing generator is faulty or has been
removed from the unit.
Incoming WAN signal is lost.
Frame Alignment is lost.
The system has received a Yellow Alarm signal from a remote device.
Usually received when the device loses WAN signal or
synchronization.
The system has received a Blue Alarm signal from a remote device.
Usually received when the remote or intermediate device has a major
failure.
The local incoming WAN signal has a serious problem and trunk
conditioning is started. After receiving a RED alarm (NOS or LOS) for
2-3 seconds, the system initiates the appropriate trunk conditioning
sequence (see voice cards for information about the TC_CGA setting)
and sends a Yellow Alarm to the remote device. If the system is in
drop/insert mode, it also sends an AIS signal to the downstream
equipment.
The system has initiated trunk conditioning in response to a Yellow
Alarm from a remote device. After 2-3 seconds, the system initiates
the appropriate trunk conditioning sequence (see voice cards for
information about the TC_CGA setting)
The error rate measured by the system has exceeded the threshold set
on the WAN card.
The Alarm Card sensor has received an alarm indication from an
attached device.
If the network side D channel looses contact with the user side, an
alarm message will be generated. The alarm message will show the
slot # and D channel # where the problem exists.
The primary card has failed and the system has switched to the
redundant card. See the Redundant Operations Chapter.
One or more active ports on a user card are not working properly.
Voice ports will show an alarm for excessive signaling transitions and
data ports will show an alarm for exceeding the data error threshold.
The system has been reset by either loss of power or by system
software upgrade.
The ACO option forces you to manually clear certain alarms. Without
this option, self-correcting alarms might not be noticed. When the
ACO option is set to either Report or Log and the modifier is set to
Major, alarms will report normally but will also generate an ACO
alarm. If the modifier is set to Minor, it will not generate the ACO
alarm. If the filter is set to Ignore, no alarms will be generated.
The SYNC alarm is generated when either the primary or secondary
external clock source is lost. This alarm is in addition to the condition
that lost the clock source (CGA-RED or OOS).
While using transcoder operations for E1 that involve downstream
tributaries, setting EER-3 to "report" will cause an alarm to appear on
the local system when E1 transmission errors exceed 10e-3 (1 in 1000).
The local EER-3 alarm will identify the effected WAN link (i.e., W1-1)
and take it out of service. Simultaneously, the downstream tributary
will receive an AIS alarm to warn them of the condition.

Reference Guide v3.6

DS3 PLCL Yellow Alarm

Physical Layer Convergence protocol is reporting a yellow alarm

Report
Setting the filter for the various alarms to report causes the alarm indication to be sent
to a remote device (see the Interface Card chapter), displays the alarm report on the
screen, and logs the alarm in the Alarm History.

Log
Setting the filter for the alarms to log, displays the alarm report on the screen and logs
the alarm in the Alarm History (see later in this chapter).

Ignore
Setting the filter for the alarms to ignore, will cause the alarm indication to be ignored
by the system.

Modifiers
Each alarm may also be designated as info, minor, major and critical. The filter
modifier shows on both the active alarm and alarm history screens.
When used in conjunction with the External Alarm card, the occurrence of any alarm
designated as critical will trigger a form-C contact on the External Alarm card which,
in turn, can serve to activate an external device such as a bell or light. Similarly, the
occurrence of any alarm designated as major would trigger a different contact and
therefore activate a different external indicator. (See External Alarm Card chapter.)

ACO
ACO (Alarm Cut Off) is an additional security feature used by the system to alert the
operator of alarms that clear themselves while the unit is unattended. If ACO is set to
report or log, any alarm set to report or log with a major modifier will cause an
additional alarm message to appear on the screen. This message, known as the ACO
alarm message, must be manually cleared by the operator. Used with the node port of
the Interface card (see Interface card chapter), ACO can also trigger some external
alarm device such as a bell or light that must also be manually cleared by the operator.
ACO alarms must be cleared from the Interface card screen.

Alarm Handling
The report alarm function attempts to send alarm information to a remote printer,
Network Management System or other logging device, in addition to logging the alarm
in the Alarm History log. These features use the built-in serial port and modem on the
Interface card. You need to change settings on the Printout Alarms screen or IP screen
on the Interface card to activate these special functions. (See Interface Card for more
information.)
Alarms set to either log or report record occurrences automatically to the Alarm
History log. You can access the Alarm History log from the Main Alarm screen by
pressing the "H" key from the Main Alarm Screen.

Reinitializing the System
Information about cards inserted, card settings, WAN connections, passwords and other
data is stored on the nonvolatile RAM (NVRAM) on the Interface Card. When most
card types are removed and replaced, the NVRAM remembers the card settings and if
the same kind of card is inserted in the slot, there will be no need to reprogram the
settings. If, on the other hand, a card is replaced with a different type of card, then the
system will offer the operator the option of deleting the old card, so that the new
parameters can be established (see Accept function in “Configuring the Cards,” earlier
in this chapter).

CPU Card
One exception to the rule in the previous paragraph is changing the CPU card type
between standard bus-connect, enhanced bus-connect or cross-connect. When a CPU
card is removed and replaced by a like CPU card, the system will reevaluate the
NVRAM and assign the old system parameters to the new CPU card (including
passwords).
If the CPU card is replaced with one of the other types of CPU card, or in some cases
with the same type of CPU card that is equipped with a different version of firmware,
the new CPU card will want to “cold-start” the system (overwrite NVRAM information
on the Interface card). The screen shown as Figure Basic-10 will be shown.

Warning: Pressing the Z command from the Menu of Actions will start the ZIP process.
"Zipping " the system deletes all of the information stored on NVRAM on the Interface
Card and resets the system. All cards must then be completely reconfigured.
When the Z key is pressed, the system will display the main log-in screen and ask for
password authorization from either Manager or Operator access levels. After the
correct password, the system will ask the question, "OK to Zip the system (y/n)"? If Y
is pressed, the system will test and reinitialize itself. All NVRAM information will be
erased from the Interface card and a new log-in screen will appear.

BACKUP
The Backup command backs up system information to a text file in the PC that is
running the terminal emulation program. The Backup command allows backup of
information on a system-wide or card-by-card basis. It also backs up Alarm Filters,
Alarm History, Installation Table and Cross Connect information. It is best to back up
information after any significant changes in system configuration and at intervals that
assure that alarm history and other operating information will be maintained
dependably. Figure Basic-14 shows the Backup Screen. The Backup procedure is

System Operations

Introduction
The primary purpose of your equipment is to maximize the use of incoming and
outgoing T1/E1 lines by assigning specific channels (DS0s) to perform voice, data and
cross-connect functions. These system operations are described in detail in this chapter.

Assigning the Timeslot Map
The system operations described in this chapter use two types of CPU, bus-connect
(Models 8800 and 8804) and cross-connect (Model 8801). For the purposes of this
chapter, the operation of the Model 8804 CPU is identical to that of the Model 8800
CPU. As a result, the 8804 CPU is not explicitly covered in this chapter. Differences
between it and the 8800 are discussed in the CPU card section.
The cross-connect CPU differs in application from the bus-connect models because of
the DS0 cross-connect module that allows you to select and assign independent
connections of one DS0 to another. In this chapter we will refer to these connections as
"pass-through" circuits because they link a DS0 from one T1/E1 link to another through
the system. Using the cross-connect CPU also allows the user to have up to eight
separate T1/E1 links on four WAN cards in any cross-connect combination possible.
The next six sections describe ways to administer the network and assemble bandwidth
portions to meet these needs. Where applicable, each section first addresses busconnect systems with Model 8800 CPUs and then cross-connect systems with Model
8801 CPUs.
Ø The first section deals with assigning incoming and outgoing user card ports to
T1/E1 channels (timeslot).
Ø The second section describes a time-saving tool known as the "Configuration"
option that automatically assigns sequential WAN timeslot to ports on analog voice
cards and allows WANs to be assigned without any cards.
Ø The third section concerns cross-connecting WAN timeslot to other WAN timeslot
in both bus-connect and cross-connect systems.
Ø The fourth section addresses a special application that is supported in cross-connect
systems only: the ability to broadcast a data signal over multiple WAN aggregates.
Ø The fifth section describes signaling status, signaling conversion and companding
conversion in bus-connect systems.
Ø The sixth section shows you how to view the timeslot map after the assignments
and cross-connects are made.

In this manual, we define "assigning timeslots" as the process of connecting user card
ports to WAN timeslots, and "cross-connecting timeslots" as the process of connecting
WAN timeslots to other WAN timeslots.

(10-97)

Page 2-D-1

System Operations

Reference Guide v3.6

Assigning Timeslots from a User Card
The timeslot map specifies the connections between all incoming and outgoing lines
connected to the system. It allows you to split the bandwidth of T1/E1 lines into
amounts appropriate for normal voice and data communications. A timeslot map
comprises all the connections you define for all the cards in the system.

Bus-Connect Model
A system equipped with a Model 8800 bus-connect CPU can access only two T1/E1
links and has two modes accessed from the WAN card screen: Drop-and-Insert (d-i)
and Terminal (term). Note: When voice is going through the d-i, signaling must be
turned on for voice to work correctly. Drop-and-Insert mode allows you to route part of
the bandwidth of one of the T1/E1 lines to user cards while the unit automatically
routes the rest to the other WAN link. In Terminal mode you can route the bandwidth
of both T1/E1 links to user cards only. A description of the process follows.
Timeslot assignment will be as unique as each customer's needs. A system using an
E&M card and HSU card in T1 operation is used as an example here to illustrate the
timeslot assignment process. Many different arrangements of timeslot assignments are
possible with these two cards. Figure System-1 illustrates of one of those ways. In
Drop-and-Insert mode, you can define a route on the timeslot map that assigns WAN
port 1-1 timeslots (TS) 1-8 to ports 1-8 on the E&M card and TS#9-16 to the first port
on the HSU card which is programmed to operate as an 8xDS0 super-rate data port.
The remaining 8 timeslots will automatically be cross-connected to the corresponding
timeslots on WAN port 1-2. The E&M card illustrates the case in which each port on
the card can be assigned to only a single WAN timeslot (see Figure System-2). The
HSU card illustrates the case in which one port may be assigned to multiple WAN
timeslots using a table (see Figure System-3). All other available cards are assigned to
timeslots in a similar manner, and specific instructions are included in each card
chapter.

You can define a timeslot map from any user card (data or voice) for connections
involving that user card, or from a WAN card for connections involving only WAN
cards. For example, Figure System-2 shows the E&M card screen for the above
example, from which you can define a timeslot map as follows:

example, this would be WAN w1-1.

3.

Select TS for each port and a number for the corresponding timeslot on the
WAN port will appear at the bottom of the screen. You can change the
number by using the up and down arrow keys and the  key.

Note: ONLY use this option to reassign the timeslots on the HSU Card to DACOM.
Otherwise, DO NOT change your vendor code.

Cross-Connect Model
The difference between bus-connect and cross-connect model 8801 is that the crossconnect model allows you to access two T1/E1 links for each of four WAN cards for a
total of eight T1/E1 links. Since there is no d-i or term mode setting, all WAN card
connections to other WAN cards are accomplished through the cross-connect option on
the main screen and must be individually specified (see later section in this chapter).
User cards on systems equipped with the cross-connect CPU are assigned to WAN
timeslots in exactly the same manner as bus-connect versions.

Using the Configuration Option
Both bus-connect and cross-connect systems support the ability to automatically assign
timeslots to E&M, FXS and FXO cards using the configuration option from the main
screen. Figure System-4 shows a picture of the timeslot assignments for four E&M
cards using E1 operations. The configure option automatically assigns the 8 ports from
E&M card #1 to timeslots 1-8, seven ports from E&M card #2 to timeslots 9-15, and the
8 ports from E&M card #3 to timeslots 17-24, timeslots 25-31 are assigned to E&M
card #4, ports 1-7. The configuration option only works with WAN ports 1-1 and 1-2.
With a T1 WAN port, the configuration option would automatically assign the eight
ports from the first E&M card to timeslots 1-8, the eight ports from the second E&M
card to timeslots 9-16 and the eight ports from the third E&M card to timeslots 17-24.

Figure System-4. Timeslot Map Using Configuration Option in E1 Operation

In order to use the Configuration Option, the following constraints apply:
Ø You must be configuring 3 vacant adjacent user slots for T1 operation or 4 vacant
adjacent user slots for E1 operation. Cards must be sequentially in order (i.e. U1,
U2, U3).
Ø You need to set the MODE on the WAN port to term.
Ø The 3 or 4 cards you intend to configure must be the same type (see below).

The following steps and series of figures demonstrate the Configuration Option in E1
operation:

Page 2-D-6

1.

Place the cursor on the first of the 4 slots you intend to install. In Figure
System-5, slots U5-U8 will be assigned to the 30 user timeslots on the E1
WAN port. Press c to initiate the configuration option.

2.

Select the type of card (E&M-600Ω, E&M (extended range), FXS-900Ω, FXS600Ω, FXO-900Ω or FXO-600Ω as shown in Figure System-5.

3.

Select the WAN port to which you wish to assign the voice cards (W1-1 or
W1-2) as shown in Figure System-6.

4.

The system automatically builds the necessary timeslot structure, but since
the user slots are vacant, the system will register Out Of Service alarms for
each of the 4 cards, as shown in Figure System-7. Inserting the four E&M
cards will turn off the alarm condition.

5.

Figure System-8 shows the WAN Xconnect screen with the correctly
assigned timeslots.

System Operations

Cross-Connecting WAN Timeslots
After assigning user cards to timeslots, the remaining WAN bandwidth may be assigned
to pass-through connections between T1/E1 links.

Bus-Connect Model
In bus-connect mode, the choice of Mode from the WAN card will automatically
determine how WAN timeslot cross-connects are made. Whatever mode is selected
will apply to both T1 and E1 links. In the d-i mode, all timeslots on one T1/E1 link
that are not assigned to user ports will be cross-connected to the other link on a one-toone basis. In the term mode, no cross-connect circuits are possible. Note that if a
Model 8804 CPU is used, then a Dual WAN card in slot W3 can only be used in term
mode. W3 Does Not support voice cards 8212, 8220 and 8221.
If the Dual WAN card in slot W1 is optioned with one T1 port (DSX or CSU) and one
E1 port (CEPT), and if that card is set to operate in d-i mode, then the cross-connect
map used by the system for unassigned ports will be as shown in Table System-1.

Cross-Connect Model
Cross-connecting WAN timeslots with the cross-connect model is performed from the
Main screen. To access this function, select "X" from the Menu of Actions on the Main
screen. Choosing "Add" from the Menu of Actions provides the fields used to program
all of the "pass through" circuits in your network. Figure System-9 shows the "Add"
fields. Table System-2 lists the circuit parameters along with the possible and default
values.

Circuit Identification
A "circuit" is defined as a group of one or more DS0s that are cross-connected from one
WAN link to another. Each circuit can carry voice or data traffic, and each is given its
own name to facilitate cross-connect management within the system. The "CIRCUIT
ID" field allows the user to define and name individual pass-through circuits. The
default value is "new circuit" and can be changed to show any pertinent title for the
pass-through connection, although each circuit ID must be unique. The title can
contain up to fourteen letters or numbers, of upper and lower case, including spaces and
underscore (_), dash (-). In Figure System-10, the circuit is identified as SF01-NY01.
Warning: When cross-connecting multiple independent data DS0s (not a superrate
circuit) between WAN aggregates in a cross-connect system, you must program each
data DS0 cross-connect independently of the others. Note: Crossconnecting multiple
DS0s in v mode maintains DS0 integrity. Attempting to save time by cross-connecting
those independent data DS0s as one superrate circuit could cause data errors. This
limitation does not apply to voice DS0s.

Figure System-10. New Circuit Selection

W/U (WAN Unit)
The first WAN Unit column is the T1/E1 link from which the pass-through connection
begins. (Since these circuits are bi-directional, the concept of beginning or ending is
used for illustrative purposes only.) The options are all of the WAN cards and ports,
and the identification uses the same convention (w1-1, w1-2, etc.) seen earlier. If a
WAN card is not present in the W/U selected, an error message is generated. The
example shown in Figure System-11, shows the selection of WAN 1-1.

The first Timeslot/Band Width column shows the different timeslots from WAN 1-1
that will be assigned to this pass-through connection. Figure System-12 shows the
selection of timeslots 8-12 from WAN 1-1 assigned to the start of the connection. Any
number of timeslots from 1-24 would be acceptable for T1 operations and from 1-15
and 17-31 for E1 operations. The bandwidth is automatically assigned. Selection is
made using the space bar and the arrow keys. The arrow key moves from slot to slot
and the space bar toggles between selecting and deselecting the timeslot.

Figure System-12. The Timeslot/Bandwidth Options

Test (for Data Circuits)
The first Test column allows the user to select the test pattern to be applied to this
circuit in the direction of the first WAN link specified. Figure System-13 shows the
options which are selected by highlighting the choice and pressing the return key. The
choices are off (no testing), all 0 (all zeros), all 1 (all ones), m_oos (Multiplexer Out Of
Synchronization), 1:1 ("one to one" pattern where a 1 is followed by one zero), 1:7
("one to seven" pattern where a 1 is followed by seven zeros), lpbk (loopback), 300 Hz
(steady 300 cycle tone), 1kHz (steady 1000 cycle tone), and 3kHz (steady 3000 cycle
tone). When the circuit is saved, the system will send the selected pattern toward the
first end of the circuit on each DS0 to facilitate testing. When circuit testing is finished,
"Test" should be returned to the "off" position. The loopback (lpbk) option places the
circuit in loopback in the direction of the first WAN link specified.
If you are dealing with a voice cross-connect circuit (with or without signaling), test
capabilities are accessed from the WAN cross-connect screen. This feature is
discussed at the end of this section.

The second WAN Unit column is the T1/E1 link in which the pass-through connection
ends. The options are all of the WAN cards and ports. If a WAN card is not present in
the W/U selected, an error message is generated. The example shown in Figure
System-14, shows the selection of WAN 3-2.

TS/BW
The second Timeslot/Band Width column shows the different timeslots from WAN 3-2
that will be assigned to this pass-through connection. Figure System-14 shows the
selection of 5 timeslots from WAN 3-2 assigned to the end of the connection. Any
number of timeslots from 1-24 would be accepted for T1 operations and from 1-15 and
17-31 for E1 operations. The bandwidth is automatically assigned. Selection is made
using the space bar and the arrow keys. The arrow key moves from slot to slot and the
space bar toggles between selecting and deselecting the timeslot. The number of DS0s
assigned to this half of the cross-connect circuit must equal the number assigned to the
other. If not, the system will reject the connections and generate an error message.

Test (for Data Circuits)
The second Test column allows the user to select the test pattern to be applied to this

(loopback), 300 Hz (steady 300 Hz tone), 1kHz (steady 1000 Hz tone), and 3kHz
(steady 3000 Hz tone). When the circuit is saved, the system will send the selected
pattern toward the second end of the circuit on each DS0 to facilitate testing. When
circuit testing is finished, "Test" should be returned to the "off" position. The
Loopback (lpbk) option places the circuit in loopback in the direction of the first WAN
link specified.
If you are dealing with a voice cross-connect circuit (with or without signaling), test
capabilities are accessed from the WAN cross-connect screen. This feature is

Type
The Type column selects the mode of operation for the pass-through circuit. Figure
System-14 shows the selection of Type. The choices are v (voice) requiring no trunk
conditioning; v&s (voice with signaling) which will preserve A/B (robbed bit) signaling
on the selected timeslots and provide trunk conditioning; and d (data) which also
supports trunk conditioning.

System Operations

CNV
The Conversion (CNV) parameter allows the user to request that PCM companding and
signaling conversion be performed on this cross-connect circuit. Since these
conversions only apply to voice circuits, if the TYPE selected is data (d), then the only
acceptable value here is n/a. Similarly, if the TYPE selected is voice without signaling
(v), the system will only allow you to request PCM companding conversion. If the
TYPE is voice with signaling (v&s), then you can select any combination of
companding and/or signaling conversion.
If the TYPE is v or v&s, the system will first ask you to "Select PCM CONV:" for
defining the type of companding conversion you require. (See Figure System-18.) The
options are no companding conversion (none), convert the incoming A-law signal to
mu-law (A-mu) and convert the incoming mu-law signal to A-law (mu-A).
If the TYPE is v&s, the system will prompt you to "Select SIG CONV:" for selecting
the type of signaling conversion needed. (See Figure System-19.) The first option is
default signaling conversion (none) where a bit pattern of "0000" will automatically be
converted to "0001" in the T1 to CEPT direction.
The second option (ANSI-CCITT) will convert the incoming ANSI signaling to CCITT
signaling. The third option (CCITT-ANSI) convert the incoming CCITT signaling to
ANSI signaling. These two options are complementary (i.e. if either one is selected in
one direction, the other is automatically selected for the reverse direction). When
convert is selected then the TC field is used to select what type of conversion is used
from the TABS field on the interface card.
The fourth option (ABCD-ABAB) will convert the incoming CEPT signaling to T1
signaling for an ESF or D4 cross-connect. The fifth option (ABCD-AB01) will convert
the incoming T1 signaling to CEPT signaling for a ESF or D4 cross-connect. These
two options are complementary (i.e. if either one is selected in one direction, the other
is automatically selected for the reverse direction).
Because of space limitations in the CNV column on the screen, the system will display
a summary notation of the choices just made. The possible values are no (no
conversion), sig (signaling is converted, but not the PCM), pcm (PCM is converted, but
not the signaling) and p&s (both signaling and PCM are converted). Figure System-20
illustrates those options.

Function
Add allows you to program additional pass-through cross-connects in
the system. If mistakes are made during the add process, pressing the
up arrow or down arrow key will terminate this operation.
The uPdate action is initiated by pressing the "p" key. With this
command, you can change any of the parameters of a pass-through
connection. As shown in Figure System-22. Use the arrow keys to
highlight the area to be changed and close the transaction using the "S"
(Save) command.
The dElete action is initiated by pressing the "e" key. Use this
command to delete existing pass-through connections. As shown in
Figure System-21, the system will prompt you to delete the circuit, and
the "y" key must be pressed to complete the transaction.
The pgUp (page up) action is initiated by pressing the "u" key. Since
the system can handle many different cross-connect circuits, you may
exceed a single screen. New pages will be added automatically to
accommodate additional circuits. The page count feature at the top of
the screen shows you the current page and the total amount of crossconnect pages. Use this command to scroll up through the pages of
cross-connect information.

pgDn

The pgDn (page down) action is initiated by pressing the "d" key. This
action is similar to the pageUp command. Use this command to scroll
down through the pages of cross-connect information.
The View all action is initiated by pressing the "v" key. This action is
used to access the Broadcast screen discussed in a later section.
The Test Access Digroups (TADs) function is a remote test access for
data cross connects that pass through the system according to
publication TR-TSY-000343, Issue #1, June 1986. A test center can
access the Integrated Access Controller and assign a non-intrusive
testing circuit between the unit and the test center via another WAN
link. See the TADs section later in this chapter.
Pressing "m" (Main) will return the user to the main cross-connect
screen.

Figure System-22. The Updated WAN Card Screen

Using the Test Option for Voice Cross-Connects
Voice and data circuits differ in the way in which the test function is accessed. While
the user can set up test patterns on data circuits on the cross-connect screen from the
main screen, users testing voice circuits must use a subscreen of the WAN Xconnect
card screen. Figure System-23 shows the error message that appears when the user
attempts to access testing of voice circuits from the CPU Xconnect screen.

Figure System-23. Message on CPU Xconnect Screen
Figure System-24 shows the WAN Xconnect screen for the voice circuit used in this
example. Place the cursor over the selected circuit and press the "t" key to bring up the
Test Screen shown in Figure System-25. This screen splits the circuit into two parts
with your location as the midpoint. The first column of test parameters will apply to
that portion of the circuit on WAN 2-1, timeslot 13. The second column of test
parameters will apply to that portion of the circuit on WAN 2-2, timeslot 13.
Table System-4 lists the test parameters along with the possible and default values.

Tx ABCD
The Transmit ABCD bit parameter allows the user to observe the bit pattern being sent
on the transmit side of the line (mon) or to set a different pattern for testing that portion
of the circuit (set). Choosing set brings up a small four character window at the bottom
of the screen and allows the user to type in a new pattern of ones and zeros. Figure
System-26 shows a diagram of the process. When Tx ABCD for WAN 2-1 is set to
mon, the WAN 2-1 column reflects the ABCD bits being sent out on WAN 2-1. This
pattern should be identical to the Rx ABCD on WAN 2-2 (unless the conversion table is
used). When Tx ABCD for WAN 2-1 is set to set, the user supplies a bit pattern of four
1s and 0s for the new ABCD bits. The Rx ABCD stream from WAN 2-2 is broken at
circle #1, and the new pattern is inserted into the Tx ABCD stream. The same applies
for mon and set for WAN 2-2. The bit stream will be broken at circle #2.

System Operations

PATTERN
The Pattern parameter allows the user to choose a test pattern to be transmitted as PCM
data on the selected side of the circuit. The options are off, all 0 (zeros), all 1 (ones),
m_oos (multiplexer out of synchronization), 1:1 (a one followed by a zero and then
another one), 1:7 (a zero followed by a one and seven zeros, then another one), lpbk
(loopback), 300 Hz (300 Hz tone), 1kHz (1000 Hz tone) and 3kHz (3000 Hz tone).
Since the Tx ABCD only changes signaling bits, this option allows the user to choose
the test pattern. A different pattern can be sent on either side of the circuit.

MON Tx ABCD
The Monitor Transmit ABCD bit information field shows the bit pattern being
transmitted on the outbound circuit. It can be changed by using the set command. This
parameter is for information only.

MON Rx ABCD
The Monitor Receive ABCD bit information field allows the bit pattern being received
on the inbound circuit. This parameter is for information only, it is not changeable by
the user.

CONVERSION
The Conversion information field shows the user the conversion setting selected from
the cross-connect screen. The possible values are no (no conversion), sig (signaling is
converted, but not the PCM), pcm (PCM is converted, but not the signaling) and p&s
(both signaling and PCM are converted). This parameter is for information only, it is
not changeable by the user on this screen.

WAN STATE
The WAN State information field shows the current status of the port. The possible
values are stdby, actv, test (the operator is actively controlling the circuit), OOS (the
WAN port is Out of Service) and CGA (the WAN port assigned has a CGA alarm).
This parameter is for information only, it is not changeable by the user on this screen.

Broadcast
One of the special features of WAN timeslot assignment in cross-connect systems is the
ability to copy a data signal and send it to multiple locations without disturbing the
original circuit. This feature is called Broadcast (meaning multi-cast, not to be
confused with broadcast quality video).
An example of this feature would be a major company that transmits data lecture from
the corporate headquarters in Denver to the sales office in San Francisco. Sales offices
in Salt Lake City, Houston and Phoenix would like to be in the data lecture as well.
The master circuit (Denver to San Francisco) is a two-way circuit (i.e., both ends can
send and receive data). The other ends of the broadcast circuits (the sales offices in Salt
Lake City, Houston and Phoenix) can only receive the output of the Denver end of the
master circuit (i.e., they will not be able to take part in the discussion in “real time”).

The following series of figures shows how the process works.
Figure System-27 shows the main cross-connect screen. In this example, T1 circuits
connected at the Denver office go to San Francisco (w1-1), Houston (w1-2), Salt Lake
City (w2-1) and Phoenix (w2-2). This screen only shows the cross-connects made from
WAN cards to WAN cards, not User cards to WAN cards.

Figure System-27. Main Cross-Connect Screen
Broadcast circuits can be initiated, updated or deleted only from the broadcast screen.
To access the Broadcast option, press the "V" (View all) selection from the menu of
options and the All Circuits screen (Figure System-28) is displayed. In addition to the
WAN to WAN cross-connects, this screen also shows User card to WAN card timeslot
assignments for all WAN cards.
Because this screen shows all WAN timeslots that are either assigned to user cards or
cross-connected to other timeslots, it could be quite full.

Figure System-28. All Circuits Screen
In addition to the two WAN to WAN cross-connects shown in Figure System-28, an
HSU circuit from slot u4-1 to the San Francisco T1 circuit on WAN 1-1 and an HSU
circuit from slot u4-2 to Phoenix on WAN 2-2 are shown in Figure System-29.
To select the broadcast option, place the cursor over the User card circuit that will be
copied (in this case, it will be the Denver end of the Denver to San Francisco link on
WAN 1-1) and press the "b" (Broadcast) key from the menu of options. The screen
shown in Figure System-29 will show the dynamics of the first copy of that circuit.
Pressing the "Enter" key allows users to access and modify connection options.

Figure System-29. Add Broadcast Screen
In this example, the broadcast circuit is labeled "Lecture" for easier identification later
when the circuit will be disconnected.
Figure System-30 shows the selection of a second destination for the broadcast circuit.
In this example, that destination is Salt Lake City, which is accessed through WAN w21. The timeslot selection is shown in Figure System-31. Selecting "S" (Save) from the
Menu of Actions will save the parameters of the new circuit. Figure System-32 shows
the new circuit. Note that the circuit type is "b/d" (broadcast/data).
Similar actions will duplicate this circuit for the other destinations. Figure System-33
shows the completed circuits.
To disconnect the circuits when the program is finished, highlight the circuit to be
disconnected with the cursor and press the "e" key and the screen shown in Figure
System-34 will appear. Selecting "y" will permanently delete the copied circuit while
leaving the original circuit intact.

Figure System-34. Delete Broadcast Circuit

WAN Link to WAN Link
Circuits from a WAN link to a WAN link can also be duplicated from the broadcast
screen. The same procedure is used to establish multiple connections for WAN to
WAN circuits.
Back in Figure System-30, highlighting the WAN link circuit on slot w1-1 will allow
you to cross-connect duplicate information to any other WAN link needed.

Function
Bcast allows you to program additional broadcast cross-connects in the
system. If mistakes are made during the add process, pressing the up
arrow or down arrow key will terminate this operation.
The uPdate action is initiated by pressing the "p" key. With this
command, you can change any of the parameters of a broadcast
connection. Use the arrow keys to highlight the area to be changed
and close the transaction using the "s" (Save) command.
The dElete action is initiated by pressing the "e" key. Use this
command to delete existing broadcast connections. As shown in
Figure System-34 earlier, the system will prompt you to delete the
circuit, and the "y" key must be pressed to complete the transaction.
The pgUp (Page Up) action is initiated by pressing the "u" key. Since
the system can handle many different circuits, you may fill the screen
allotment for data. New pages will be added automatically to
accommodate additional circuits. The page count feature at the top of
the screen shows you the current page and the total amount of pages of
information. Use this command to scroll up through the pages of
cross-connect information.
The pgDn (Page Down) action is initiated by pressing the "d" key.
This action is similar to the pgUp command. Use this command to
scroll down through the pages of cross-connect information.
Pressing "m" (Main) will return you to the cross-connect screen.

Test Access Digroups (TADS)
The Test Access Digroups (TADS) is a remote test access for data cross connects that
pass through the system according to publication TR-TSY-000343, Issue #1, June 1986.
A test center can access the system and assign a non-intrusive testing circuit between
the unit and the test center via another WAN link. For the purposes of this discussion
on Test Access Digroups, the figures show a 64kbps data circuit between Fremont, CA.
and Jacksonville, FL. Figure System-35 shows the cross-connect screen with the data
circuits connected.

Pressing the "L" command from the Menu of Actions allows you to split the circuit
through the data test center equipment. New circuit information is added in the same
way as with the monitor circuit.
With the Split Circuit, the data test center splits the circuit and connects it to their
equipment. Unlike the Monitor test circuit, the Split test circuit is intrussive and all
transmit and receive data must pass through the equipment at the data test center.
Figure System-39 shows the TADS screen with a split circuit completed. It uses two

Terminate and Leave Access
The Terminate and Leave Access (TLA) circuit gives the data test center the capability
to terminate one or both directions of transmission on a circuit by inserting an
unassigned channel code (01111111) in the outgoing transmission path(s). The TLA
feature is useful in circuit provisioning to turn circuits up and down remotely, and in
testing multipoint circuits to isolate and remove noisy bridge legs from service.
Figure System-42 shows the TLA screen with the choice of Monitor (mon) or
Unassigned Channel Code (uca) to be applied to the highlighted circuit. (If TLA had
been applied to a Split circuit, the choices would have been spl or uca.)

System Operations

Signaling and Companding Conversion in Bus-Connect
Systems
User card ports may or may not have a signaling mode applied to them when assigned
to a timeslot. Typically, analog voice cards (i.e., E&M, FXO, FXS) will have their
analog signaling information converted to digital signaling bits which are then inserted
into the digital bitstream. Data card circuits (i.e., HSU, SRU, etc.), on the other hand,
do not require the system to perform any signaling processing or conversion.
Unlike DS0s terminating on voice or data cards in the system that will have controlled
signaling parameters, circuits that "pass through" your system must have signaling
assigned to them by the user. This ensures that the WAN cards either maintain existing
signaling patterns as in T1-T1 circuits or change and convert them for circuits going
from a T1 to an E1 environment.
In Figure System-43, timeslots 1-8 and 13-18 are connected to user cards and therefore
will have signaling automatically turned off or on by the system depending on the type
of user ports that are assigned to them. Of the pass-through connections on the other
timeslots, you can either select signaling or no signaling depending the type of
equipment or channel facility on which it is ultimately terminated. For voice circuits,
you would probably want to enable signaling, and for data equipment, you would
probably want to disable signaling (the default). Further, this screen allows you to
request that signaling conversion and/or companding conversion be performed on passthrough circuits.

Reference Guide v3.6

To change the signaling and/or companding options of a voice circuit on a WAN card
using the drop-and-insert mode, place the cursor over the timeslot you wish to change
and select I (sIgnaling) from the Menu of Actions. Table System-7 shows the matrix of
choices for the handling of signaling, signaling conversion and companding conversion.

Select SIG
TYPE
(no choice)
e&m, fxs,

(no choice)

The first option is Select Signaling. The choices are either yes or no, depending upon
the type of circuit passed through the system (voice or data). Whichever choice is
made, the system will then prompt you to select PCM companding conversion. The
choices for Select PCM CONV are none, A-mu (A-Law to Mu-Law, E1 to T1
conversion) and mu-A (Mu-Law to A-Law, T1 to E1 conversion).
On a normal data service, you would probably choose no and none. A voice circuit on
a T1-T1 "pass through" might require signaling enabled but not converted, so the
choices would be yes (to pass voice signaling through), and none (the PCM does not
have to be converted), and none (the signaling does not have to be converted).
If, for instance, you have an international voice circuit passed through your system to a
North American T1 circuit, you would probably need to have both signaling and PCM
conversion converted. Choosing yes for Select Signaling will bring up your Select
PCM CONV options, followed by a prompt to select the signaling conversion for this
circuit.
The first option is default signaling conversion (none) where a bit pattern of "0000" will
automatically be converted to "0001" in the T1 to CEPT direction.
The second option (ANSI-CCITT) will convert the incoming ANSI signaling to CCITT
signaling. The third option (CCITT-ANSI) converts the incoming CCITT signaling to
ANSI signaling. These two options are complementary (i.e. if either one is selected in
one direction, the other is automatically selected for the reverse direction).
The fourth option (ABCD-ABAB) will convert the incoming CEPT signaling to T1
signaling for an ESF or D4 cross-connect. The fifth option (ABCD-AB01) will convert
the incoming T1 signaling to CEPT signaling for a ESF or D4 cross-connect. These
two options are complementary (i.e. if either one is selected in one direction, the other
is automatically selected for the reverse direction).
If signaling conversion is enabled for that circuit, you will then be asked to Select SIG
TYPE. The choices are e&m, fxs, plar and fxo. After this final choice, the screen
updates the signaling and conversion information on that circuit.

Checking the Timeslot Map
Once the timeslots are selected and assigned, the list of all DS0 connections (the
timeslot map) can be viewed through the WAN card Xconnect screen for both busconnect and cross-connect systems. (In the bus-connect version, changes of signaling
status [trunk conditioning] can also be done from this screen [see previous section]).
You can see the results of your assignment selections by checking the timeslot map as
follows:
1. From the Main Screen, select the WAN card in slot W-1.
2. Type  to bring up the timeslot screen (see Figure System-45).
3. Selecting  for Main will return you to the WAN card screen.
4. Selecting  for Main again will return you to the Main screen.

Figure System-45. Timeslot Screen in T1 Operation
Figure System-46 shows the same example displayed on a bus-connect system using E1
connections in d-i mode. (Timeslot #16 will not be available for assignment on
either the HSU table or the voice card timeslots.) Like T1 operation in d-i mode,
unspecified timeslots are automatically assigned to corresponding slots on the other
WAN port on the same card.

DACOM Timeslot Renumbering
The WAN Card timeslot selection screen shown above can be modified for DACOM
format. The timeslot data will be translated into DACOM format using a new assigned
vendor code. This will allow the renumbering of timeslots so they will be displayed into
Korean format.
If Vendor Code indicates DACOM, then renumbered timeslots will be displayed using
the Korean format. Timeslots 1 through 15 will be unchanged. Timeslots 17 through 31
will be renumbered as 16 through 30, and timeslot 16 will be renumbered as 31.
Note: ONLY use this option to reassign the timeslots on the WAN Card to DACOM.
Otherwise, DO NOT change your vendor code.

Figure System-46. Timeslot Screen in E1 Operation

Recording the Configuration on Paper
After you set up your initial system configuration and define your timeslot map, take
the time to record this information on paper. Recording the initial configuration in a
logical manner will pay for itself if you have a problem later.
Record the information in any way that makes sense to you and your colleagues.
Whatever your approach, it is suggested that you also note the initial settings for each
card in copies of the T1 or E1 operation tables provided as Tables System-8 and -9.
Store all the initial configuration information in a safe place where anyone needing to
service the system can easily find it.

Redundant Operations

Introduction
The system can be configured with redundant features that will switch operations from
failed critical components to "backup" replacements with the minimum loss of service
possible in the event of equipment failure.
The four areas of redundant operations are the power system (load share), the CPU
card, the WAN card and the ADPCM network.

Power System
Each of the power supply components is designed to switch to alternative units (if
available) in the event the primary unit fails. Additionally, the defective unit will
create a system alarm upon failure to alert the operator of the condition so that suitable
diagnostic and repair work may be initiated. The units covered by these redundancy
parameters are:
•

8901 AC Power Supply

•

8902 DC Power Supply

•

8906 Ringing Generator (Master only, see below)

•

8907 DC Power Supply

Upon failure, the LED on the 8903 or 8905 AC to DC Power Converter will be turned
off but will not generate a system alarm (unless the system is equipped with the 8902
External Alarm card).
If the "Master" 8906 Ringing Generator fails, an alarm will be generated and the LED
will turn off. If a "slave" Ringing Generator fails, the LED will turn off but no alarm
will be generated by the system.
Figure RDNT-1 shows the main screen of a cross-connect system in which Power
Supply #1 (PS1) has failed. The Power Supply failure is noted in the alarm message in
the top right hand corner of the screen.

Figure RDNT-1. Redundant Power Systems (Two-Sided Chassis)

CPU Card
CPU Card redundancy is valuable to the user because of the criticality of the CPU card
to the operation of the entire system. CPU redundancy is supported in both crossconnect and enhanced bus-connect units using two 8801 or 8804 models respectively.
A CPU card installed in slot C2 will become the redundant mate of the one in slot C1, if
they are both of the same type.
Switching from one CPU card to the other is triggered by any one of the following
conditions:
•

A software command issued by the operator

•

Removal of the active CPU card

•

Failure or malfunction of the active CPU card

During a CPU redundancy switch over, disruptions to voice and data traffic are
momentary and traffic will recover automatically.
Figure RDNT-2 shows the Main screen of a cross-connect system. The CPU in slot C1
is active and the CPU in slot C2 is the redundant mate. When the command
"cpusWtch" is selected from the Menu of Actions, the system will prompt the user with
the yes/no question.
Figure RDNT-3 shows the same screen after the switch. The CPU card in slot C1 now
shows redundant and the CPU in slot C2 now shows as the active mate. Note: This
switch is intrusive and will cause an outage.

Figure RDNT-3. CPU Switchover (Front-Loading Chassis)

WAN Card
T1 and E1 WAN redundancy is supported in enhanced bus-connect systems (Model
8804 CPU) and in cross-connect systems (Model 8801 CPU). It is not supported in the
standard bus-connect systems (Model 8800 CPU).

(10-97)

Page 2-E-3

Redundant Operations

Reference Guide v3.6

In both cases, the user may define in software, one or more events that can trigger a
WAN redundancy switchover from among the following options:
•

A software command issued by the operator

•

The removal of the active WAN port or card

•

The failure or malfunction (OOS) of the active WAN port or card

•

CGA alarm declaration on the active WAN port or card

During a WAN redundancy switchover, disruptions to voice and data traffic are
momentary and traffic will recover automatically.

Enhanced Bus-Connect WAN Redundancy
In enhanced bus-connect systems, a single or dual WAN card that is installed in slot W2
automatically becomes the redundant mate of the WAN card in slot W1. Similarly, a
WAN card in slot W4 automatically becomes the redundant mate of the WAN card in
slot W3. This is known as 1x1 redundancy and a "Y-adapter" (Model 1239) is required
to bring the outputs of each pair of WAN ports onto the same facility. The "master"
WAN card and its redundant mate must be equipped with the same mix of DSX, CSU
or CEPT modules and those must be placed in the same positions on both cards. If an
incompatible WAN card is installed in a redundant slot, then the system will "reject"
that card. If a Dual WAN is used in "terminate" mode, only the failed WAN port will
switch to its redundant mate. If the Dual WAN card is programmed for "drop and
insert" mode, both ports will switch even if only one has failed.
Figure RDNT-4 shows the Main screen (status screen selected) of the enhanced busconnect system. In this example, the two ports on WAN-1 are paired with the two ports
on WAN-2, while the two ports on WAN-3 are paired with the two ports on WAN-4.
Figure RDNT-5 shows the main WAN card screen for the card in slot W3 with port 1
selected. The software command "sWitch" is selected from the choices in the Menu of
Actions and the system delivers the prompt shown in the same figure. Pressing "y" will
complete the transaction and the traffic on WAN port 3-1 will be switched to WAN port
4-1. The main screen (Figure RDNT-6) now shows WAN port 4-1 as the active port
and WAN port 3-1 as the redundant port.
Note: There are no internal test functions available for WAN #3 or #4.

Figure RDNT-6. RCON WAN Cards (Two-Sided Chassis)

Cross-Connect WAN Redundancy
In cross-connect systems, WAN redundancy requires the installation of a Dual WAN
card with Relays (Model 8014) in slot W4. That WAN card with Relays acts as the
redundant card for the WAN cards installed in slots W1 through W3 provided it is
equipped with matching DSX, CSU or CEPT plug-in modules and that the plug-in
modules are installed in the correct positions. This is known as 1xN redundancy and,
following a redundancy switchover, the relay module on the 8014 switches the output
of the redundant WAN card to the correct pins on the WAN connector of the Interface
card. Note that if a Model 8014 Dual WAN card with Relays is installed in slots W1,
W2 or W3, then it will function as a standard Dual WAN card. Also, if the plug-ins of
a Model 8014 installed in slot W4 do not match those of a WAN card in slot W1,
W2 or W3, then it cannot act as that card's redundant mate. Even though the
system will not reject the card, it will simply not switch even if the active WAN card
fails. Finally, if a standard WAN card is installed in slot W4, then WAN redundancy
cannot be supported by the system. In cross-connect systems redundancy
switchovers occur on a WAN card (not port) basis and the whole card must match
the redundant card in slot W4 for the switchover to occur. Note: In the 8014 there
must never be a physical T-1 connection to WAN 4 that is being used as a Redundant
WAN.
Figure RDNT-7 shows the main screen (status screen selected) of a cross-connect
system. In this example the two CSU ports in WANs 1, 2 and 3 are backed-up by the
two ports in W4.

ADPCM Card
This system can employ ADPCM cards that use voice compression technology to
effectively increase the digital voice transmission capabilities of voice cards (E&M,
FXS or FXO) or WAN links. See the ADPCM chapter in the Server Cards section for
complete technical details about the ADPCM card.
Each system allows one, two, or three ADPCM cards located in slots P1 through P3,
depending on slot availability. In systems with two or three ADPCM cards, any one of
the cards can be selected as the redundant backup. No restrictions exist about slot
order.
Figure RDNT-10 shows a console with three ADPCM cards. The ADPCM card in slot
P1 is highlighted. Pressing the "Enter" key will bring up the ADPCM main screen
shown as Figure RDNT-11.

Figure RDNT-12. The ADPCM Card Main Screen
Should either card in slots P2 or P3 fail for any reason, the entire voice compression
network will switch to the redundant card in slot P1. When the Out of Service
condition is repaired, the card in the slot that previously failed will become the
redundant card for the system.
The system does not have to have any of the ADPCM cards redundant. All three slots
(P1-P3) can be used for traffic on ADPCM voice networks.

CPU Card

Introduction
This section discusses the installation and operation of the CPU card. It describes the
three types of CPU Cards and includes the following main topics:
Ø CPU Card Settings
Ø Printing Alarms Remotely
Ø TCP/IP Network Management
Ø Network Statistics
Ø Routing

The CPU Card controls all operations of the system. One CPU Card is required for all
installations. Two Models 8801 or 8804 CPUs can be used for CPU redundancy.

8800 CPU Card
The 8800 is the base model CPU Card. It supports up to two T1 or E1 WAN ports (on
one WAN Card). The 8800 requires that you install the WAN Card in slot W1 and that
all channels be assigned to time slots on links W1-1 and W1-2. A system that uses an
8800 CPU card is said to operate in "standard bus-connect" mode. The 8800 CPU does
not support redundant operations.

8801 CPU Card
The 8801 CPU card supports complex applications requiring more than two WAN ports
and the ability to cross-connect DS0s between WANs. The 8801 supports up to four
WAN Cards for a total of eight T1 or E1 WAN ports and has a built-in cross-connect
module. A system that uses an 8801 CPU card is said to operate in "cross-connect"
mode. Two Model 8801 CPUs can be installed in slots C1 and C2 to achieve CPU
redundancy. The 8801 also supports 1xN WAN redundancy. (See the Redundant
Systems chapter.)

8804 CPU Card
The 8804 CPU supports two T1 or E1 WAN links in slot W1-1 and W 1-2 with a
redundant card (similarly configured) in slot W2. It supports another two T1 or E1
WAN links in slot W3-1 and W3-2 with a redundant card (similarly configured) in slot
W4. If the T1/E1 link in w1-1 fails for any reason, the system will automatically switch
to the similarly configured card in slot w2-1 (W1-2 would switch to W2-2 in the same
way).
Slot W3 can support either a Single or a Dual T1/E1 WAN card. If the T1/E1 link in
w3-1 fails for any reason, the system will automatically switch to the similarly
configured card in slot w4-1 (w3-2 would switch to w4-2 in the same way).

Reference Guide v3.6

Note that WAN ports in slot W3 can operate only in "terminate" mode and can
only support 8202, 8213 or 8215 HSU card ports and OCU-DP ports from an 8247
5 or 10-port OCU-DP card. No other voice or data ports can be assigned to the
WAN card in slot W3 in this mode.
A system that uses an 8804 CPU is said to operate in "enhanced bus-connect" mode.
Two Model 8804 CPUs can be installed in slots C1 and C2 to achieve CPU redundancy.
The 8804 also supports 1x1 WAN redundancy. (See the Redundant Systems chapter.)

Figure CPU-1. CPU Card Screen
The CPU screen has ten setting fields: Node ID, four passwords, System Contact
Person, System Location, System Phone Number, Alarm Sequence and Alarm Cutoff.
The Node ID must be unique within each user’s network for each unit. The
“Superuser” password level is reserved for use by factory personnel only.
The other three levels are referred to as "manager," "operator" and "viewer"
respectively. The user sets these values on the CPU card screen, shown in Figure CPU1. Each password can be up to 14 characters long (alphabetic and numeric only). Note
that passwords are case-sensitive. For more information about passwords, and changing
the settings on this card, refer to “Logging On” in the Basic Operations chapter.

Page 3-A-2

(10-97)

Reference Guide v3.6

CPU Card

The System Contact Person is the name of the person to contact.
The System Location is where the system resides.
The System Phone Number is the phone number used by a remote user to engage the
system in a VT-100 session (using either ISDN D channel dialing or the Remote
Integrated Terminal System described in the Interface chapter). Up to ten numeric
characters can be placed in this field.
The Alarm Sequence establishes how the sequence number for alarms is generated. If
this parameter is set to all, any alarm generated by the system will be assigned a
sequence number. If this parameter is set to report , only those alarms set to report will
be assigned a sequence number. See the Basic Operations chapter for additional
information on setting alarm reporting characteristics.
The Alarm Cut Off (ACO) option reports a status to the user based on the setting latch
(condition held) or cur (current condition).
The CPU screen also displays the status of each CPU (Active or Redundant), the type of
CPU installed and the version of the voice and host software.

Changing Passwords
Depending on the security procedures for your network, you may need to change
passwords frequently. The best passwords are at least 6 and no more than 12 characters
long, are not found in a dictionary, and contain both letters and numbers. Because the
system is case-sensitive, you can capitalize some of the letters in the passwords to give
you more possible combinations. Perform the following steps to change the system
passwords:
1.

Log on to the system at the Manager access level and select the CPU card
from the main screen.

2.

Highlight the password you want to change and press the  key.

3.

Type the new password (up to 14 characters, alphanumeric, case sensitive
(no spaces allowed)) over the old password and press the  key.

4.

Make sure the password appears as you want it (passwords are casesensitive) and save your changes.

Entering Values in Fields
To change the value in a field:

(10-97)

1.

Use the arrow keys to scroll to the field.

2.

Press the  key to open the entry area at the bottom of the screen.

3.

If the system offers a set of choices, use the arrow keys to scroll to your
choice and press  again.
If data entry is required, type in the data and press .

4.

When desired entries have been made press s (Save) to save the entries.

Printing Alarms Remotely
Often integrated access controllers are placed in unsupervised locations (equipment
closets, etc.). With no one present to detect alarms that might occur, the system
administrators have no way of knowing that the unit is not operating properly.
The basic solution to the Network Management problem is the Print Alarm feature.
Each system can be programmed to call a predetermined telephone number at specific
intervals and report the presence of selected system alarms. Alarms are chosen to print
remotely by selecting the Report option in the alarm filters (see Basic Operations
chapter).
The user can employ either an external modem (with faster transmission rates) or the
internal modem (2.4kbps) on many of the Interface cards to send system alarms to a
remote logging device such as a printer or personal computer. If using the internal
modem, the user should connect the remote device to a V.22 bis 2.4kbps asynchronous
modem set to auto-answer, eight data bits, one stop bit, and no parity. When the
modem connected to the remote logging device answers, the system sends the alarm
messages as a string of ASCII characters formatted with carriage returns and line feeds
and hangs up the call. More information on this process can be found later in this
chapter.
The network administrator can also call the phone number associated with the system
modem and initiate a two-way, interactive VT-100 session with the system to determine
the nature of the problem and dispatch technicians if necessary.
Another Network Management solution is the TCP/IP feature discussed later in this
chapter. If the TCP/IP network management system is active, the Print Alarm
feature will not operate.
Using the TCP/IP feature automatically converts alarm messages into SNMP traps for
forwarding to downstream NMS equipment.

Reference Guide v3.6

PRT ALARMS
The Print Alarms option sets parameters for alarm output to a remote device. The
system uses the modem on the Interface card to call a remote device or Network
Management System. The system sends the alarm information for all alarm filters set
to Report (see “Alarms” in the Basic Operations chapter). Set the Printout Alarms
setting to off to disable all external alarm-generated messages. The direct setting sends
all alarms reported since the last report cycle to a local device through the DB-9
computer port. The modem setting sends all alarms reported since the last report cycle
to a remote device through the modem port.
The remote device may be any asynchronous ASCII device which can accept lines of
text up to 80 characters long. It must support XON/XOFF flow control and be capable
of attaching to an asynchronous dial-up modem. Figure CPU-3 shows an OOS alarm
reported to a remote device.
The device’s modem must be compatible with CCITT Rec. V.22 bis and support
connections at 2.4kbps. Set the modem for auto answer mode. Both the device and
modem should be set for 8 data bits, 1 stop bit, and no parity.

PRT PHONE#
The Print Phone Number is the number the modem dials when sending alarms to the
remote device. The number may be up to 14 digits long.

PRT RETRY
The Print Retry field determines the number of time the system will wait between
attempts to redial the remote device. The retry interval can be from 1-60 minutes.

PRT ATTEMPTS
1.

The Print Attempts is the maximum number of times the system attempts
to contact the remote device before giving up. The number of attempts
can range from 1-99.

PRT MAJOR
The Print Major field is the maximum number of time the system will wait from the
occurrence of a major alarm until it places a call to the remote device to report it. The
interval-cycle can be from 1-500 seconds. All alarm reports designated as "Major"
(see “Alarms” in the Basic Operations chapter) will be reported at that time. For
example, if the user specifies an interval-cycle of 300 seconds (5 minutes), every major
alarm that occurs during a 5 minute period will be reported at the end of that cycle.
The Print Major interval-cycle starts from the most recent of:
1.
2.
3.

Page 3-A-6

The end of the last Major cycle (if no alarms occur).
When parameters are saved using the Save command from the Menu of
Actions.
40 seconds after the last alarm message is reported.

(10-97)

Reference Guide v3.6

CPU Card

PRT MINOR
The Print Minor field is the maximum number of time the system will wait from the
occurrence of a minor alarm until it places a call to the remote device to report it. The
interval-cycle can be from 1-32,000 seconds. All alarm reports designated as "Minor"
(see “Alarms” in the Basic Operations chapter) will be reported at that time. For
example, if the user specifies an interval-cycle of 3,600 seconds (60 minutes), every
minor alarm that occurs during a 60 minute period will be reported at the end of that
cycle.
The Print Minor interval-cycle starts from the most recent of:
1.

The end of the last Minor cycle (if no alarms occur).

2.

When parameters are saved using the Save command from the Menu of
Actions.

3.

40 seconds after the last alarm message is reported.

When the specified interval-cycle for major or minor alarms is reached, the system will
send a list of the accumulated alarms sorted by the elements below. To avoid
congestion, alarm reporting is limited at the remote device or Network Management
System to the first 40 lines of non-reported alarms. The system will then wait 40
seconds and send the next 40 lines, and continue sending in that way (i.e. 40 lines, wait
40 seconds) until finished with the entire list of non-reported alarms. Forty seconds
after the last alarm message is reported, the new interval-cycle starts.

ELEMENT 1-6
The elements of the alarm configuration (see the Basic Operations Chapter), alarm,
model, address, time, severity, number, or empty can be arranged in any order that is
most helpful for the user. For instance, the user might want the order of the alarm
configuration to be severity, time, model, address, alarm, and number, while another
might want the sequence to be model, time, alarm, address, severity, and number.
Elements 1-6 can order these variables in any way needed.
NO=Node_1
AK=7
NU=00038
AL=OOS
ML=8840

TCP/IP Network Management
This section presents another type of Network Management System supported by this
unit for diagnosing and reporting trouble at unsupervised locations. SNMP alarm traps
and TELNET configuration can transmit over this path. Both formats can use the 4kbps
FDL (Facility Data Link) on a T1 link using ESF format, the SA4 on an E1 link, a full
DS0 on a T1/E1 link, or the computer port of the Interface card using SLIP protocol.
If you do not understand the NMS concepts of IP addressing, SNMP, SLIP,
TELNET and Ping, please consult with your network administrator before
attempting to install or repair components presented in this section.
If the FDL is used to transmit and receive information, a Lucent Technologies DACSII
(6.1 or higher) or DACSII ISx (3.0 or higher) is used to convert the FDL/IP information
to a full DS0. (On a point-to-point circuit, a DACSII is not needed.)
If you have a small number of remote units to supervise, one of the Network
Management System options is to use a B7R (Bit-7 Redundant) card at the NMS site.
One through eight remote units send alarm information on the FDL/SA4 of a DS1 to
either a DACSII on eight individual DS0s and multiplex the contents into a single
38.4kbps asynch circuit using SLIP protocol for use by a communication server or
terminal server for routing to a Local Area Network. (See B7R card chapter.)
Using IP addresses, the network management center can communicate directly with the
affected unit, diagnose the problem, and dispatch a technician if necessary.
Figure CPU-4 shows how a typical system might be set up to make use of this feature.
This figure shows eight integrated access controllers (from different geographic
locations) reporting alarms through the TCP/IP interface to workstations at the network
site using the procedure mentioned above.

1. The user options depend upon the selection in the Default IP Port selection. All user
options are explained below.

HOST IP STATUS
The Host IP Status is the IP address status for this specific integrated access controller.

HOST IP ADDR
The Host IP Address is the IP address for this specific integrated access controller. If
the B7R is used for this NMS, the Port IP address must be the same as the one entered
in the ADDR field of that card.

HOST NETMASK
The Host Netmask is used to indicate how much of the IP address is used for host
addressing and how much is used for network addressing. If the B7R card is used for
this NMS, this address must be the same as the one entered in the NETMSK field of
that card.

DEFAULT IP PORT
The Default IP Port setting tells the CPU card where IP packets will be sent or received.
The options are off (to disable Network Management System), local (information will
be sent over the DB-9 computer serial port to NMS equipment), wan (information will
be sent over the WAN FDL or a DS0 [chosen on the WAN card main screen with
ESF/NMS RPT option]), or serv (information sent over WAN DS0s through the
Ethernet connection to the NMS equipment).
If this parameter is set to local, wan or serv the Print Alarms feature (mentioned in the
previous section) must be set to off. If local is chosen for this setting, the internal
modem will not operate.

Page 3-A-10

DEFAULT IP SLOT
The Default IP Slot options are determined by the choice of Default IP Port. If off or
local is selected for that parameter, this option will show n/a. If wan is selected, the
options for this parameter will show W1-W4 (the WAN card slot that transmits and
receives NMS information). If serv is selected, the options for this parameter are P1-P3
(the Server card slot that transmits and receives NMS information).

DEFAULT IP UNIT
The Default IP Unit options are determined by the choice of Default IP Port. If off or
local is selected for that parameter, this option will show n/a. If wan or serv is selected
above, the options for this parameter will be 1-2 (corresponding with the WAN or
Server port).

RPT1 IP ADDR
The RPT1 IP Address is the IP address of the first Network Management System host
running a SNMP trap server.

RPT1 COMMUN STR
The RPT1 Community String holds the community string for the first NMS host
running a SNMP trap server. The community string provides additional security by
rejecting messages that do not contain the correct string. There must be some entry in
this field to enable RPT1.

RPT2 IP ADDR
The RPT2 IP Address is the IP address of the second Network Management System
host running an SNMP trap server.

RPT2 COMMUN STR
The RPT2 Community String holds the community string for the first NMS host
running an SNMP trap server. The community string provides additional security by
rejecting messages that do not contain the correct string. There must be some entry in
this field to enable RPT2.

RPT3 IP ADDR
The RPT3 IP Address is the IP address of the third Network Management System host
running an SNMP trap server.

Routing
The system supports multi-point routing of Internet Protocol (IP) packets to either a
local Network Management System over the computer port or to a remote NMS over
the B7R card, timeslot #24 or the Facilities Data Link (FDL) of a T1 link. (For E1 links,
the information is sent on the B7R card, timeslot #31 or the SA4.)
If you want to use an entire timeslot (either 24 or 31) for remote NMS routing, no
action needs to be taken. If a B7R card is used or you want to use the FDL or SA4, an
additional selection must be made on the WAN card. For T1 links the selection is made
on the ESF/NMS RP parameter and on E1 links it is made on the COM/NMS RP
parameter. (See the WAN card and B7R card chapters for further information.)
All packets arriving on any of the optional paths or the local port will be treated by the
IP stack as follows:
•

If the packet's destination address matches that system's address, the packet is
processed locally.

•

If the address is not the same, the unit will search the routing table to find a remote
address that matches the destination of the packet.

•

If a match is not found for the packet, it is routed to the interface specified in the
DEF DEST field. If the default destination matches the interface the packet arrived
from, the packet is dropped.

All IP addresses between the Remote Start and Remote End addresses must go to the
same WAN link. If you are unclear about IP Addresses, please consult with your
Network Administrator.
Figure CPU-10 shows a typical routing application. Even though 24 integrated access
controllers are used in this example, the number of remote units is virtually unlimited
except for bandwidth and link-down considerations.

Figure CPU-10. Routing Feature Diagram
In the diagram above, 24 integrated access controllers will transmit alarm information
to an IP routing Controller (System 25) by the optional paths of separate WAN links.
The network administrator assigns IP addresses for each system on the TCP/IP screen of
each unit's interface card (PORT IP ADDR). System 20 is connected by any of the
optional paths to System 25 which supports NMS equipment (the communications
server) by either a local SLIP connection directly from the CPU card or any of the
optional paths of a WAN link. In this example, all alarms received by any of the 24
Controllers will be forwarded to Controller 25 on a single WAN link.
Each of the 24 reporting units use System 25's IP address as the RPT1 IP ADDR on the
TCP/IP screen of its interface card. First routing is initiated by the off/on command for
each sub-unit. The IP address for REM STRT is the lowest IP address of the sub-units
controlled by that port. The IP address for REM END is the highest IP address of the
sub-units controlled by that port. The local port is included to be able to transmit the IP
packets generated by the routing unit to the same destination. In most cases, the DEF
DEST of all units controlled by this router will be the same place (either the local port
or optional WAN paths to a distant location).
The column headings are associated with the incoming WAN link associated with the
IP location of the remote systems. For example, if you expect incoming information
from system #1 on WAN 1-1, you would assign the IP address for system #1 between
the REM STRT and REM END for WAN 1-1.
Figure CPU-11 shows the Routing screen and Table CPU-6 lists the options for that
screen.

ADPCM Card

Introduction
The 8871 ADPCM card is a plug-in resource card for the system. The card has 32 pairs
of voice compression engines that accept input directly from voice, SRU or BRI cards
in the same system unit or voice traffic on WAN links through the system. ADPCM
cards require a matching card at the other end to decompress the voice channels to
normal 64K operation. Except for SRU which uses h link to extract data from timeslot.
Each pair of compression engines utilize one 64Kbps DS0 for two compressed
channels. In Figure ADPCM-1 the eight numbers at the top of the screen represent the
first four pairs of compression engines. Each engine can compress 64Kbps voice traffic
to either 24Kbps, 32Kbps or 40Kbps (depending upon compression quality needed).
The rate of any DS0 is 64Kbps, so the sum of the compression rates for engine #1 and
#2 must equal that figure. If, for instance, you assign a 32Kbps circuit to engine #1,
engine #2 can only accept a 32Kbps circuit. A 40Kbps circuit can only be paired with a
24Kbps circuit and vice-versa.
The compression engines work in pairs. Engine numbers 1 and 2, 3 and 4, 5 and 6, 7
and 8, are paired. Each member of the pair must have the same ADPCM WAN and
ADPCM TS. Additionally, both members of the compression engine pair must be active
before either port will operate.
The ADPCM card can compress low speed asynchronous data transmission (19.2Kbps
or less) from an SRU port that will occupy a 24Kbps engine. Each data circuit must be
paired with a 40Kbps voice channel. It can also compress B channel voice traffic from
the BRI card without restriction of compression rates.
Each unit can have up to three ADPCM cards installed (two normal ADPCM cards and
one redundant card). See the Redundant Operations chapter for further information
about redundant ADPCM cards.
The ADPCM card supports Transition Signaling as defined by ANSI T1.302-1989 with
the exception of the Alarm bits. ANSI T1.302 specifies signaling at the 32Kbps
compression rate. The ADPCM card uses this scheme for 24Kbps and 40Kbps although
it is not included in the standard. Table ADPCM-1 summarizes the signals supported by
each transcoder data rate. User channel configuration must adhere to these
specifications.

STATE
The State setting determines whether the port is active or inactive. When assigning
ADPCM engine pairs for WAN traffic, set the State setting to stdby (standby) for ports
you are not using or have not yet configured. Set it to actv (active) for ports that are
ready for use.

Page 4-A-2

Reference Guide v3.6

ADPCM Card

Setting the State to rdnt (redundant) for any port on an unused card will cause that card
to act as the redundant back-up for all of the other ADPCM cards in that unit. Once a
card is designated as a redundant ADPCM card the only way it can be used for regular
ADPCM traffic is to change the state of the selected port back to either actv or stdby .
When assigning ADPCM engine pairs from user cards, changing the port from stdby to
actv and saving the selection information on the user card screen will cause the system
to automatically assign an ADPCM engine.
When the engine is assigned from a user card, no changes can be made from the
ADPCM card screen to any of the fields.

USER
The User setting identifies the User card and port connected to this engine. This is the
place where the ADPCM card will expect incoming (not compressed) voice, sub-rate
data or B channel traffic. If assigned from a voice card, SRU or BRI card port, this
selection will show the user slot and port number (i.e. u5-2 for the card in slot U5, port
#2). If you are assigning a WAN timeslot, this setting will show n/a.

WAN/SERV
The WAN/SERV setting identifies the incoming WAN or server link connected to this
engine. This is the place where the ADPCM card will expect incoming (not
compressed) voice. This option shows the choices: none, w1-1through w4-2 and MORE
on the first line of choices. If you select MORE it offers the choices of P1, P2, or P3.
Choose none if you are assigning from a voice card or SRU card port; choose from w11 - w2-4 if assigning from a WAN card, and P1-P3, if assigning from a server card.

TS
The Timeslot parameter selects the specific timeslot on the WAN link chosen in the
previous setting that the ADPCM card can expect incoming voice traffic. The options
are determined by the equipment on the WAN link selected in the previous setting. If
WAN 1-1 is equipped with either a CSU or DSX module, the options are 1-24. If a
CEPT module is installed on that link, the options are 1-15 and 17-31 . If you are
assigning from a voice card, SRU card or BRI card port, this setting will show n/a.

ADPCM W/S
The ADPCM W/S setting identifies the outgoing WAN link to which the engine is
connected. This option shows the choices: none, w1-1through w4-2. If you are
assigning either from a voice card, SRU or BRI card port or voice traffic from a WAN
timeslot, this setting will show w1-1 through w4-2. This is the WAN link to which the
ADPCM card will route outgoing (compressed) traffic.

ADPCM TS
The ADPCM Timeslot parameter selects the specific timeslot on the WAN link chosen
in the previous setting that the ADPCM card will send outgoing compressed traffic. The
options are determined by the equipment on the WAN link selected in the previous
setting. If WAN 1-1 is equipped with either a CSU or DSX module, the options are 124. If a CEPT module is installed on that link, the options are 1-15 and 17-31 .

Page 4-A-3

ADPCM Card

Reference Guide v3.6

TYPE
The Type parameter identifies the voice and signaling requirements for the incoming
circuit. The options are v (voice), v&s voice and (signaling) and trnsp (transparent).
The v setting is used when the input to the ADPCM channel is a 64Kbps channel and
inband signaling is not required. The v&s setting is used when the input to the ADPCM
channel is a 64Kbps voice channel and the ADPCM card must provide inband
signaling.
The trnsp setting allows the user to map the output of SRU ports to the ADPCM
channel. Sub-Rate Data will be clocked into the ADPCM channel at an input rate equal
to 24Kbps and then passed transparently (non-compressed) through the ADPCM card to
the appropriate WAN timeslot. This could be useful when the user has an odd number
of voice channels and wants to utilize the empty engine pair of the last ADPCM
channel.
B channel traffic from the BRI card also uses the trnsp Type setting but is not restricted
in its compression rates.
If the engine is assigned from a voice card, this selection will show v&s. If assigned by
an SRU or BRI card, it will show trnsp . It cannot be changed from this screen.

RATE
The Rate parameter identifies the compression requirements for the incoming circuit.
The options are 24K, 32K and 40K (the pair of engines must be equal to 64Kbps).
If this engine is assigned from a user card port, the selection will show the value that
was chosen on that port. It cannot be changed from this screen.

SIG MODE
The Signal Mode parameter identifies the type of signaling required for the incoming
circuit. If v&s was chosen in the Type setting, the options are e&m, fxs, plar and fxo. If
v or trnsp were chosen in the Type setting, the only option is n/a.
If this engine is assigned from a user card, the selections are uX-1 through uX-8. The
default is n/a.

CODING
The Coding parameter identifies the PCM format required for the incoming circuit. The
choices are u-law or a-inv .
If this engine is assigned from a voice or BRI card, this selection will show the value
that was selected for that port. If this engine is assigned from an SRU card, this
selection will show u-law . It cannot be changed from this screen.

If this engine is assigned from a voice card, this selection will show the value that was
selected on the voice card port. If assigned from an SRU or BRI card port, the field will

WAN Card

Introduction
This section discusses the WAN cards and the plug-in modules that define their
communications functions. It covers physical configuration of the plug-in modules and
their installation as well as the software configuration, monitoring and testing of the
cards after installation.
WAN cards manage the flow of data through your network. They are also the point of
T1/E1 termination and generate or receive clocking. Both CSU and DSX modules are
used to connect to T1 facilities operating at 1.544 Mbps. The CEPT module is used
internationally for connection to a 2.048 Mbps E1 facility.
WAN cards equipped with CSU or DSX modules will also act as the "near end"
termination point for Subscriber Loop Carrier (SLC96) facilities as outlined in
publication TR-TSY-000008, Issue 2, August 1987.
Additional information about WAN card functions is included in the Installation
chapter, System Operations chapter and Redundancy chapter.

811 DSX/CEPT Plug-in Module
The DSX/CEPT plug-in module supports either DSX or CEPT modes. It is mounted on
the WAN Card. DSX is a T1 operation and CEPT is an E1 operation. Jumper settings
on the module specify DSX or CEPT operation. Information about installing the
module and changing jumper settings is included in this chapter.

812 CSU Plug-in Module
The CSU plug-in module is required for Channel Service Unit (CSU) operation in a T1
environment. Like the 811, it is mounted on the WAN Card.

820 HDSL E1 Plug-in Module
The HDSL E1(High-bit-rate Digital Subscriber Line) module is a plug-in for the 8011
HDSL E1 WAN card. It provides transport for E1 rate (2.048 mbps) data over copper
cable without mid-span repeaters or conditioning.

8000 Single T1/E1 Link Card
The single T1/E1 Link Card is the basic WAN Card. It has a single port for DSX/CEPT
or CSU operation.

8010 Dual T1/E1 Link Card
The dual T1/E1 Link Card has two ports for either DSX/CEPT or CSU operation or a
combination of the two. The Dual T1/E1 Link Card will work with only one plug-in
module as long as the WAN port without the plug-in module remains in the standby
state. However, a CGA_RED alarm will be generated for that port.

8014 Dual T1/E1 Link Card (with Relays)
In Cross-Connect systems, the dual T1/E1 Link Card (with relays), when placed in slot
W-4, acts as a redundant card for up to three standard WAN Cards located in slots W-1,
W-2 and W-3. This is known as 1xN redundancy. The relay module on this card will
switch its output to the correct pins on the WAN connector on the Interface Card. If
placed in any other slot, it will behave like an ordinary WAN card.
Note: If the plug-ins of the Model 8014 installed in slot w4 do not match those of a
WAN card in slot w1, w2 or w3, then it cannot act as that card’s redundant mate.

8011 HDSL E1 WAN Card
The 8011 HDSL E1 WAN Card is a dual-port card that provides HDSL services by
incorporating the 820 HDSL E1 plug-in module.

811 WAN Module
When installing the 811 CSU/DSX module on the 8000 WAN or 8010 WAN, there are
situations in which the plastic standoffs do not allow the module to seat correctly on the
WAN board (see Figure WAN-1).

Figure WAN-1. Removal of Plastic Standoffs - 811 WAN Module

When assembling and installing the module on the WAN card, it is our advice that the
plastic standoffs be removed to eliminate the possibility of errors on the associated
T1 or E1 lines. For this reason, the plastic standoffs are no longer being supplied by
the manufacturer for new WAN modules.

Setting Jumpers for Balanced/Unbalanced E1 Operation
E1 links can be set either to be balanced or unbalanced by setting jumpers on the
DSX/CEPT Plug-in Module (811) or the 1183 external distribution panel, or both. (See
Table WAN-1 for information on which revisions of the DSX/CEPT Plug-in Module
have jumpers.) The 1183 and 118320 connector block mounts in place of the cover on
the 8916 and 891620 front-loading chassis (see Figure WAN-13) and connects to the
Interface Card via a 50-pin cable. Each BNC connector has its own jumper. The 1184
connector block mounts on the 8918xx chassis.

Balanced Operation
For balanced E1 operation, the jumpers on both the 1183 panel and each DSX/CEPT
Plug-in Module should be set to "balanced" prior to installation.

Unbalanced Operation
For unbalanced E1 operation, the jumpers should be set to "unbalanced" in one location
only, and set to "balanced" in all other cases. When multiple cards with jumpers are
installed, the unbalanced jumper should be set on the card nearest the E1 line.
When the 1183 or 1184 panel is present, it is considered nearest to the E1 line, and the
corresponding jumper on the rear of the panel would be set to "unbalanced" while all
other module jumpers would be set to "balanced."

Installing CSU, DSX/CEPT Modules (811, 812, 820)
Plug-in modules used to activate WAN cards must be installed prior to insertion of the
WAN card into the unit. Figure WAN-13 shows a diagram of the WAN card and the
correct placement of these modules. If, for example, your system had a T1 link (DSX)
and an E1 link (CEPT), you would receive two DSX/CEPT modules. Using Figure
WAN-14 as a guide, place the DSX module in the slot reserved for WAN 1-1 (reference
only, not shown this way on actual card). Insert the pins for TX in JP #10, while
simultaneously inserting the pins for RX in JP #9 and the 24-pin end connector pins in
JP #6. After changing the jumpers to convert the DSX module to CEPT, place the
CEPT module in the slot reserved for WAN 1-2. Insert the TX pins into JP #15, the RX
pins into JP #14, and the 24-pin end connector pins into JP #13.
The CSU module connectors are inserted in the same manner.

Valid options for Bus Connect systems are term and d-i. The only valid
option for Cross-Connect systems is xcon.

2.

These options are valid only if you have a CSU and the Line Code is ami.
If you have a CSU and the Line Code is b8zs, then this setting will default
to n/a. If you have a DSX module, then this setting will always default to
n/a.

3.

These options are valid only if you have a CSU. If you have a DSX
module, then the possible options are 0 (default), 133, 266, 399, 533, 655,
and csu.

4.

The settings for AIS/ALM vary greatly by the settings of other parameters.
A complete matrix of AIS/ALM settings is shown as Table WAN-4 later
in this chapter.

5.

If the format is d4 or slc96, the only option to appear will be none.

6.

If there is no redundant WAN card in the appropriate slot the only option
that will appear is n/a.

7.

Selection of GROUP is a two-step process. After identifying the group
number (1-4), the user must select the secondary group (A, B or C). A
which point TC ODR will then become available.

WAN Card

WAN Card Parameters
The following paragraphs describe the parameters for the DSU/DSX WAN cards shown
in Figure WAN-15 and Table WAN-2.

STATE
In standby state, the WAN port is electrically disconnected from the external network.
Set the State setting to standby (stdby) when setting up your WAN links, then change it
to active (actv) when starting normal operations.

MODE
In bus-connect systems, WAN cards have two possible modes of operation, Terminal
and Drop-and-Insert. Terminal (term) mode is for channel bank applications. All
timeslots must connect to a port on a user card or remain unconnected. Drop-and-Insert
(d-i) mode automatically connects all timeslots on WAN link #1 to the corresponding
timeslots on WAN link #2 of the same card. You can assign any or all of the timeslots
to voice and data ports by overriding the automatic setup. See the Systems Operations
chapter for more information about using these two modes, and about timeslot maps in
general. In cross-connect systems, the Mode automatically defaults to (xcon).

FORMAT
The Format setting specifies the framing to be used on the WAN link so that it matches
the framing used by your T1 carrier. Set the Format parameter based on the type of
framing your T1 carrier requires. If you are using an external Channel Service Unit
(CSU), the framing format must match that of the CSU. The options are d4 (normal
superframe), esf (extended superframe) and slc96 (subscriber loop carrier).
Table WAN-3 (on the next page) lists the DS0 time slots and the corresponding SLC
assignments (taken from TR-TSY-000008).

LINE CODE
The Line Code setting matches the coding used by your T1 interface to that used by
your T1 carrier or CSU. Set the Line Code setting based on the type of encoding your
T1 carrier uses. If you are using an external CSU, the line coding must match that of
the CSU. The options are ami and b8zs.

PULSE
For CSU modules configured for ami mode only, the user must also specify if the
system should ensure pulse density (also known as ones density) or if that responsibility
belongs to the attached customer equipment. In z15s mode, the system will monitor the
outbound data stream and will place a “1” in the 16th bit position whenever it detects
fifteen consecutive zeros. Obviously, this can lead to data corruption. In Transparent
mode (trnsp), the system will pass all incoming data transparently (the DTE must
provide 1s density). If the Line Code parameter for the CSU is b8zs, then Pulse will
default to trnsp. If the WAN link is equipped with a DSX plug-in, then this option will
automatically default to n/a.

LINE LEN
Use the Line Length setting to adjust the T1 signal strength to the distance that it must
travel before it encounters the next T1 device or repeater. For the DSX module, the
options are 133, 266, 399, 533, 655 feet or csu which is used to connect to the
equipment side of a co-located external CSU. In addition, there is an option called 0
that allows the DSX module to talk to the network side of a co-located external CSU
over a short-distance four-wire cable. For a CSU module, the three options are 0, 7.5
and 15.0 which define the amount of attenuation (in dB) that will be applied to the T1
signal before it is transmitted. Provisioning the circuit for 0 will result in the strongest
possible signal whereas a setting of 15.0 will generate the weakest possible signal.

SLIP LIM
Slip Limit defines how many bits of wander the T1 aggregate card will tolerate before
forcing a frame slip. The options are 126 and 138 bits which correspond to all old and
more recent versions of the relevant specification.

AIS/ALM
The AIS/ALM setting, allows the user to specify the type of “keep-alive” signal known
as AIS/ALM (Alarm Indication Signal/Alarm) that the system will generate on one
T1/E1 should the other fail. The AIS/ALM setting is dependent upon the format
selected for this WAN unit. Table WAN-4 shows AIS/ALM settings for Bus Connect
and Cross-Connect systems using the different FORMAT settings.

In Bus Connect and Redundant Bus Connect systems, the only option available for D4
framing is none (no AIS signal is to be generated). The options for ESF framing are
none, frm for a framed alarm signal and unfrm for an unframed alarm signal. The
options for SLC-96 framing are note (network office terminating equipment), orb16
(Office Repeater Bay - 16 frames) and orb13 (Office Repeater Bay - 13 frames).
In Cross-Connect systems, the options available for D4 framing are none (no AIS signal
is to be generated) and tcodr (transcoder operations). Selection of tcodr can only be
assigned after selection of the Group option. The options for ESF framing are none,
frm for a framed alarm signal and unfrm for an unframed alarm signal. The options
for SLC-96 framing are note (network office terminating equipment), orb16 (Office
Repeater Bay - 16 frames) and orb13 (Office Repeater Bay - 13 frames).

LINE LB
The Line Loopback setting controls looping of the full T1/E1 line back to the network,
as shown in Figure WAN-16. The options are off and on. When on, this setting allows
end-to-end testing of the line.

LOCAL LB
The Local Loopback setting controls looping of the full T1/E1 line back to the PCM
bus, as shown in Figure WAN-16. The options are off and on. When on, this setting
allows testing of local equipment.

The Channel Loopback setting allows you to select the type of local loopback for
individual DS0 channels or the WAN aggregate. A channel loopback loops a single
DS0 channel back towards the PCM bus (see Figure WAN-17) and cannot be used to
loop multiple DS0s or a portion of a DS0. Refer to user cards for other loopback
options which may allow you to loop part of a channel or multiple channels.
The loopback can be off or clear (clr). “Clear” means that the entire 64kbps clear
channel will be looped back, but without the Robbed Bit Signaling (RBS), if any, that is
embedded in this channel.

LB ADDR
The Loopback Address setting, in conjunction with the Channel Loopback setting,
specifies which channel is to be looped back. Only one channel may be looped back at
any one time for each T1 link. The valid selections for T1 lines are 1-24.

LB GEN
The Loopback Generate setting generates in-band diagnostic codes that are sent to the
remote equipment These codes are ANSI T1.403 compatible with DS1 networks and
allow you to command a latching loopback at remote DS1 equipment. The options are
off, llb (Local Loopback), plb (payload Loopback [when the entire signal, excluding
the framing bit, is looped back]) and nlb (Network Loopback).

LB DET
This option allows the card to detect DS1 channel loopbacks. When set to off, no T1
loopbacks can be detected. When set to on, T1 loopbacks will be detected and
maintained until a loop down is detected. The with/time-out (w/to) is the same as on
except that if no loop down is detected after 10 minutes, the loopback will selfterminate.

Reference Guide v3.6

ESF/NMS RP
This setting specifies the format in which performance statistics for the T1 link will be
gathered and stored in the system. In ESF mode, these performance statistics are
accessible to the carrier over the Facilities Data Link (FDL) as well as to you through
the user interface. The options are none, at&t, ansi, both, c-fdl and c-b7r. The at&t
option means that the statistics are gathered in accordance with AT&T Publication
54016 whereas the ansi option means that the ANSI T1.403 specification will be used.
You can also specify that the information should be stored in both AT&T and ANSI
modes simultaneously by selecting both. Performance statistics are also available for
D4 formatted T1 lines. See the section on T1 Performance Monitoring in this chapter
for more detailed information on this topic.
The choice of c-fdl disables telco-side capability to access performance monitoring
information. The c-fdl option sends and receives network management information
over the facility data link. The c-b7r option sends and receives the same information
over timeslot #24 on the WAN link highlighted.

EER THRHD
The Excessive Error Rate Threshold selects the error rate at which an alarm is declared.
This setting interacts with the EER setting in the Alarm Filters of your system. (See
Basic Operations chapter.) The options are 10e-4 through 10e-9 or none.

RDNT RULES
The selection of Redundancy Rules will define the method of determining what event
will trigger a WAN port to switch to its redundant mate. The options are none, OOS or
CGA. See the Redundancy Chapter for more information about redundant WAN
operations. If there is no redundant WAN card in the appropriate slot or there is an
ISDN or ADPCM card in the system, the only option that will appear is n/a.

GROUP
The Group setting identifies a method of link-fail alarm propagation from upstream
trunks to downstream tributaries when the system is configured for transcoder.
Selection of group is a two-step process. After identifying the group number (1-4), the
user must select the secondary group (A [child group], B [child group] or C [parent
group]).
Figure WAN-18 shows two Integrated Access Controllers with "parent-child"
groupings. Child groups are designated as "A" and "B." Parent groups are designated
"C." At this time TCODR may be turned on if alarms are to be propagated to distant
end.

Figure WAN-18. Using WAN Groups

For the purposes of this discussion, the WAN links between the Device and the
Integrated Access Controller (A, B, A1, and B1) will be called “tributaries” and the
WAN link between the two Controller Units (C and C1) will be referred to as a “trunk.”
In the normal condition (no WAN groups selected), a failure on any of the tributaries
supplying Device #1 would be reported at Integrated Access Controller #1 and Device
#1 only. A failure of the trunk (C to C1) would be reported at Controller #1 and #2
only.
When Groups are created at both systems, a trunk failure (C to C1) will inform all of
the associated tributaries (A and B, A1 and B1) of that condition.
When Groups are used in conjunction with the Network Management option
(mentioned earlier) and the AIS/ALM is set to tcodr, a failure of any of the tributaries
will propagate the failure through the trunk to the associated tributary at the other end
(A to A1 or B to B1).
The following notification procedure is followed:
1.

A Loss of Signal, Loss of Frame, Error Rate Exceeded or AIS failure of
the transmit leg of W1-1(A) between Device #1 and Integrated Access
Controller #1 occurs.

2.

Controller #1 detects the failure on the receive leg and declares an alarm
for W1-1(A).

3.

Controller #1 sets the A Bit (Yellow Alarm) in the transmit leg of W11(A). Device #1 detects this condition and knows not to use W1-1(A).

4.

Controller #1(C) sends an alarm message to Controller #2 (C1) that W11(A) is either CGA_RED or AIS.

5.

Controller #2 sets the transmit leg of W3-1(A1) into AIS (CGA_RED).
Device #2 detects this condition and knows not to use W3-1(A1).

When the original failure is corrected, the alarm is also cleared for downstream
tributaries.

Cross-Connect (XCON)
The Cross-Connect (Xcon) command in the Main WAN screen allows you to view the
Cross-Connections that have been set up in the system. Highlight one of the WANs on
the card and type x (Xcon) to select Cross-Connect. Either an E1 screen (Figure WAN19) or a T1 screen (Figure WAN-20) will appear, depending upon the WAN
highlighted. This is a display-only screen. Timeslot and cross-connect configuration
are discussed in the System Operations chapter of this manual.

Figure WAN-20. T1 Cross-Connect Display

Performance Monitoring
Performance monitoring is supported on all WAN aggregates. The performance
monitoring screen is accessed by typing the p (Perf) command from the WAN card
main screen Menu of Actions. Performance statistics are accumulated for 15 minute
increments that include the current period and the previous 96 periods that are accessed
by the pgUp and pgDn commands from the Menu of Actions.
In the T1 environment, an error is defined as any CRC6, Controlled Slip or Out of
Frame error for "esf" format and any Bipolar Violation (BPV), Controlled Slip or Out of
Frame error for the "d4" format. In the E1 environment, an error is defined as any
CRC4, Controlled Slip or Out of Frame error.
Figure WAN-21 shows the T1 performance monitoring screen (the E1 screen is similar
except for the Menu of Actions). The performance statistics are gathered and displayed
in fifteen-minute intervals. Periods when no seconds have accumulated are represented
by lines in each of the columns. Table WAN-8 identifies the error conditions.
Two sets of registers accumulate performance data for T1 WAN links. The user
registers and the network registers are driven by the same errored events. However,
they can be cleared at separate times. The user may view both the user and network
registers but may only clear the user registers. The network has access to only the
network registers and can clear only network registers. E1 WAN links have only one
set of registers.
Table WAN-9 shows the Menu of Actions for the Performance Monitoring Screen.

Parameter

Display

ES

Errored Seconds (ES) registers the number of seconds with one or more CRC6
(ESF), BPV (D4) or CRC4 (E1) errors, OR one or more OOFs, OR one or more
Controlled Slips.

UAS

Unavailable Seconds (UAS) shows the number of seconds during which service is
unavailable. An unavailable signal state is declared after ten consecutive
Severely Errored Seconds (SESs) are logged. An unavailable state is cleared after
ten consecutive non-Severely Errored Seconds are logged. Unavailable Seconds
are also accumulated if the card has an out-of-service (OOS) condition.

SES

A Severely Errored Second (SES) is any second with 320 or more CRC6 (ESF),
BPV (D4) or CRC4 (E1) errors, OR one or more OOF errors.

BES

A Bursty Errored Second (BES) is any second with more than one and less than
320 CRC6 (ESF), BPV (D4) or CRC4 (E1) errors.

LOFC

The Loss of Frame Count (LOFC) is the accumulation of Loss Of Frame (LOF)
conditions. LOF is declared after 2.5 seconds of continuous Loss Of
Synchronization (LOS) or Out-Of-Frame (OOF) condition. LOF is cleared after
no more than fifteen consecutive seconds without an LOS or OOF condition.

SLIP

A Slipped Second contains one or more Controlled Slips. A Controlled Slip is the
deletion or replication of a DS1/E1 frame by the receiving equipment.

DM

A Degraded Minute (DM) is any minute during the reporting period that contains
more than 10-6 errors as described in CCITT G.821. The count for this field is 115 rather than 1-900 for the other fields.

STATUS

Status displays error codes for conditions that occur during a fifteen minute
interval. Identifying codes are displayed at the bottom of the screen. Values are Y
(Yellow Alarm received), N (No Signal), T (Test Mode - line loop, local loop,
payload loop or standby), L (Loss of Synchronization - 2 out of 4 frame bits in
error), O (Out of Service), B (Bipolar Violation) and E (Excessive Error Rate).

BERT
Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected WAN port. The patterns that can be selected are off, mark (all ones),
space (all zeros), 1:1 (one-zero-one-zero), 1:7 (zero-one-6 zeros), 3:24 (3 ones-24
zeros), qrss (quasi-random pseudo signal), lp-up (which sends a T1 loop-up code to the
remote end) and lp-dn (which sends a loop-down code to the remote end). Loop-up (lpup) and loop down (lp-dn) codes are not supported for CEPT WANs.

SYNC
Synchronization (SYNC) displays yes if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test
equipment, no if it has not.

BE
Bit Error (BE) displays the total number of bit errors logged.

ES
Errored Seconds (ES) displays the total number of seconds in which errors were
detected.

SES
Severely Errored Seconds (SES) shows the total number of seconds in which the bit
error rate exceeded one bit per thousand (1 x 10-3).

(10-97)

Page 5-A-25

WAN Card

Reference Guide v3.6

CSES
Consecutive Severely Errored Seconds (CSES) is triggered by the occurrence of ten
consecutive Severely Errored Seconds. Once triggered, the CSES field will increment
(by one) for each elapsed second until the system logs ten consecutive non-Severely
Errored Seconds.

OSS
Out of Synchronization Seconds (OSS) shows the number of seconds that the BRI
BERT has been out of synchronization.

BER
Bit Error Rate (BER) shows the rate at which errors are being logged. BER equals the
number of bit errors (BE) divided by the total number of bits transmitted during the test.

ELAP
Elapsed time (ELAP) is the total number of seconds elapsed during the test.

LB STATE
The Loopback State indicates that a loopback from a remote device is both present and
operational. The field will show pl-lb (payload loop-back) when the entire signal,
excluding the framing bit, is looped back. The field will show l-lb (line loop-back)
when the entire signal is looped back. It will show none if the WAN port is not in
loopback.

STATE
Leave the card in standby (stdby) when setting up your WAN links; then change it to
active (actv) when starting normal operations.

MODE
In bus-connect systems, WAN cards have Terminal (term) and Drop-and-Insert (d-i)
modes of operation. In Terminal mode, used for channel bank applications, all
timeslots must connect to a port on a user card or remain unconnected. Drop-andInsertmode automatically connects all timeslots on WAN link #1 to the corresponding
timeslots on WAN link #2 of the same card. You can assign any or all of the timeslots
to voice and data ports by overriding the automatic setup. See the Systems Operations
chapter for more information about using these two modes, and about timeslot maps in
general. In cross-connect systems, Mode automatically defaults to xcon, the only
available option.

FRAME
Selects frame types: Cyclic Redundancy Check, 4th level (crc) or Dual Frame (d-frm).

TS16
Selects signaling usage of slot 16: Channel Associated Signaling (cas), Common
Channel Signaling (ccs) or No Signaling (nos). In the CAS and CCS, timeslot 16 is
used to carry signaling information for all channels on the E1. If nos is selected, then
timeslot 16 becomes available for user data.

Page 5-A-28

(10-97)

Reference Guide v3.6

WAN Card

EVEN BIT
Setting the Even Bit parameter for inv causes the system to invert every even bit in
every DS0 timeslot, insuring ones-density. This option should be used only if the entire
E1 stream is composed of PCM voice.

AIS/ALM
Specifies the type of “keep-alive” signal known as AIS/ALM (Alarm Indication
Signal/Alarm) that the system will generate on one E1 should the other fail. AIS/ALM
will show none until the GROUP is selected

LINE LB
Controls looping the full E1 line back to the network. On enables, off disables end-toend testing of the line.

LOCAL LB
Controls looping the full E1 line back to the PCM bus. The options are off and on. On
allows testing of local equipment; off disables testing. The system generates a “Keep
Alive - Type 1” pattern on the E1 line.

CH LB
Enables individual DS0 channel loopback toward the PCM bus (see Figure WAN-16
earlier in this chapter). A channel loopback loops a single DS0 channel and cannot be
used to loop multiple DS0s or a portion of a DS0. Refer to user cards for other
loopback options which may allow you to loop part of a channel or multiple channels.
Clr enables, off disables loopback.

LB ADDR
The Loopback Address specifies which channel is to be looped back in the Channel
Loopback. Valid selections for E1 lines are 0-31. Do not loop timeslot 16 unless the
E1 interface is in no signaling (nos) mode.

LB GEN
LB GEN generates in-band diagnostic codes that are sent to the remote equipment
These codes are compatible with DDS networks and allow you to command a latching
loopback at remote DDS equipment. The options are off, llb (Local Loopback), plb
(payload Loopback) and nlb (Network Loopback).

COM/NMS
Communications/Network Management System Report tells the system where to send
TCP/IP packets from the NMS configuration selected on the Interface card. The
options are none (no NMS), c-sa4 (use SA4 channel for NMS information) and c-b7r
(send NMS information to a B7R card on timeslot 31).

Reference Guide v3.6

EER THRHD
Excessive Error Rate Threshold selects the error rate at which an alarm is declared.
This setting interacts with the EER setting in the Alarm Filters of your system. (See
Basic Operations chapter.) The options are 10e-4 through 10e-9 or none.

RDNT RULES
Redundancy Rules define the method of determining what event will trigger a WAN
port to switch to its redundant mate. The options are none, OOS or CGA. See the
Redundancy Chapter for more information about redundant WAN operations. If there
is no redundant WAN card in the appropriate slot, or there is an ISDN or ADPCM card
in the system, the only option that will appear is none.

GROUP
Group identifies a path of link-fail alarm propagation from upstream trunks to
downstream tributaries. Selection of group is a two-step process. After identifying the
group number (1-4), the user must select the secondary group (A [child group], B [child
group] or C [parent group]). The group setting is normally used for transcoder
applications.

Cross-Connect (XCON)
The Cross-Connect (Xcon) command in the E1 HDSL WAN Main WAN screen allows
you to view the Cross-Connections that have been set up in the system. Functionality
and screens are the same as those for the WAN cards (CEPT) discussed earlier in this

Performance Monitoring
Performance monitoring for the HDSL E1 WAN card is essentially the same as for the
T1 WAN, except that only a single set of registers is used. Therefore only the
Clearregs command appears in the menu of actions, as shown in Figure WAN-25.

Figure WAN-27. Typical HDSL Performance Monitoring Screen
(local 15-minute interval)
The above screen shows the number of error conditions detected in loops 1 and 2 (local
or remote), in either 15-minute or 24-hour increments. This allows for four different
possible displays:
•

15-minute intervals, Local Loop (default)

•

15-minute intervals, Remote Loop

•

24-hour intervals, Local Loop

•

24-hour intervals, Remote Loop

You can alternate between screens by selecting from the actions at the bottom of the
screen. When 15-minute intervals are active, pressing “h” (24 Hr) switches to 24-hour
intervals (see Figure WAN-25). Pressing “i” (15 mIn) in the 24-hour interval mode
switches to 15-minute intervals. Similarly, pressing “e” (rEmote) from the Local screen
switches to the Remote screen, and pressing “l” (Local) from the Remote screen
switches to the Local screen.

The only difference between the 15-minute and 24-hour interval screens is the historical
time periods shown on the left side of the screen. In 24-hour intervals, seven historical
time periods appear, corresponding to the activity over the past seven twenty-four hour
monitoring periods, providing one week of historical monitoring data. (Note that these
will be blank if monitoring has just started.)
In 15-minute intervals, 12 historical time periods are shown on the left side of the
screen. By selecting 'D' (pgDn) from the Menu of Actions, the user can view historical
time periods 13 through 24. Pressing 'D' again will display historical time periods 25
through 32. These periods correspond to the activity over the past thirty-two 15-minute
monitoring periods, thus providing eight hours of historical data.

Introduction
The interface card provides all communications connections to the system. This section
discusses general Interface Card information, as well as specific settings for the
Interface Card.
All Interface cards must be installed in the IF slot on all chassis.

8920 Interface Card
The 8920 Interface Card has communications, control and network interface ports (see
Figure Interface-1). It features an internal modem that facilitates remote
communication with the system unit. The 8920 has a DB9 (DTE-male) serial port for
network management and two RJ48 jacks that connect to the node port for alarm
notification and VT-100 control terminal port. Additionally, an RJ11 jack is available
for the modem port. The 8920 supports eight T1 or E1 WAN links.

Interface Card Ports and Functions
The Interface card controls many critical functions in the system. It provides interfaces
to external control devices, terminates all T1 and E1 WAN links, and holds the
nonvolatile RAM and the internal modem. Table Interface-1 lists the interface ports
and functions. Figure Interface-6 shows the component layout and labels the ports. See
the Pinouts chapter for electrical specifications and pin assignments.

Internal Modem
The internal modem is an asynchronous CCITT V.22 bis modem. It allows remote
access to the terminal interface and automatic logging of alarm messages to a remote
device. Table Interface-2 lists the parameters and rating specifications of the internal
modem.

Logging On Remotely
Normally a local network operator uses a VT-100 terminal to directly access the
terminal interface. But where central control or service access is required, the internal
modem provides an access method to the terminal interface from a remote location. .
The modem automatically answers any incoming calls. The modem communicates at
2.4kbps using 8 data bits, one stop bit and no parity
To initiate a call, the remote operator dials in using a VT-100 compatible terminal. The
remote operator can press the  key to display the log-on screen. After entering
a valid password, the remote operator has complete access to the terminal interface as
described in the Basic Operations chapter.
To disconnect, the remote operator logs off and hangs up the line. The modem
automatically resets and waits for another call.
If an operator is logged on to the system with a local terminal when a modem call is
received, he will automatically be logged off the system and will not be able to restore
local access until the modem connection is broken.

Page 6-A-7

Interface Card

Reference Guide v3.6

Using the Node Port
The node port allows the system to report ACO (Alarm Cutoff) alarms to an external
system to alert the operator to critical situations. Using the ACO function, (see Basic
Operations chapter), keeps the alarm active until manually cleared from the terminal.
The node port uses an RJ48 connector. Pins 3, 4 and 5 form an RS485 compatible ccontact closure that can be used to report ACO alarms to an external system. Pins 1, 2,
6 and 7 are reserved for future use. Pin 8 is a ground.
Connecting the ACO alarm interface to an external alarm device (such as a buzzer or
light) alerts you to problems with the system. Figure Interface-7 shows a possible
configuration connecting a unit to a generic external alarm system. The nominal input
is 5V and the short-circuit current is 250mA. See the Pinouts chapter for pin
assignments.
The alarm interface is activated by the ACO setting discussed in the Basic Operations
chapter. This will activate the device when a designated alarm occurs. The Basic
Operations chapter fully discusses conditions and settings necessary to enable this
feature.

PRIMARY CLK
The Primary Clock provides all internal timing for the system. Two clock sources are
possible: a network source or the internal crystal oscillator.
A network clock source provides the best Primary Clock source. If you use a network
clock source, you must specify the WAN link to which the clock source is connected;
for example, w1-1. A WAN clock source will be either 1.544 or 2.048 Mbps depending
on whether you are using a T1 or E1 line and must be accurate to ±50 parts per million
(or ±50 x 10-6).

(10-97)

Page 6-A-9

Interface Card

Reference Guide v3.6

Alternatively, the system can generate a clock from its own crystal. If you select int,
the crystal provides the clock source for this unit. The stability of this Stratum 4 clock
is ±25 parts per million (or ±25 x 10-6). If you use the system internal crystal as a clock
source, all other devices attached to the network should derive their clocking from the
internal clock as well. The Primary Clock can be set to external (ext), but this feature
is not supported in this release.

SECONDARY CLK
Should the Primary Clock signal fail, the system automatically reverts to the defined
Secondary Clock source. This source may also be a WAN link or the internal crystal.
Although a secondary clock source is not required, good network design dictates that
you have a backup if one is available. This clock cannot be external. Selection of ext
will generate an error message.

EXTERNAL CLK
Reserved for future use.

CURRENT CLK
The current clock shows the clock now in operation. This field is not accessible by the
user.

Signaling Conversion Tables
The Signaling Conversion Tables are especially useful when cross-connecting a T1
(ANSI) voice circuit to E1 (CCITT). Changing the ABCD signaling bits to facilitate
proper signaling between the two carrier types may be necessary for proper system
operation.
All types of voice circuits (E&M, FXS, FXO and PLAR) can access the ABCD
Signaling Bit Conversion Tables for changes to their respective patterns.
The user can accept the default bit pattern changes or manually override those settings
and choose a different bit pattern and insert it into the table. Figure Interface-9 shows
the Conversion Tables accessed by pressing the "B" (taBs). Each voice circuit type is
represented by two columns corresponding to CCITT to ANSI (C->A) and ANSI to
CCITT (A->C) conversion of ABCD bits.

For instance, an E&M circuit in the "0101" state will send "0101" from the CCITT end
of the circuit and the ANSI end would receive "1111" Conversely, the same state
would be sent as "1111" from the ANSI end and received at the CCITT end as "0101."
Either receive bit pattern can be manually overridden by the user.
The E&M portion of the conversion table is also used for DN, PLAR-D3, DPO and

Remote Terminal System (RTS)
The Remote Terminal System (RTS) is a special application for users using microwave
transmission. Using communication software, a user can log into any number of
different systems from a single control station (PC, MAC, Sun, or HP Workstation) to
download alarm information, change card settings, and perform maintenance.
Systems are connected from the Interface card’s COM port to a wireless control
network through the RS232 input on one of the four service channels on the wireless
network. The Control Station (PC) is connected to pin #2 out and #3 in. Each of the
integrated access controllers is connected to RS232 pin #2 in and pin #3 out.
The actual number of the systems that can be connected together is determined by the
amount of different numbers that can fit in the “SYS PH#” field in the CPU sub menu.
The CPU sub menu is accessed by selecting a CPU through the user interface and
pressing the  key.

Identification
Each system has a unique identification number on the integrated access controller
network (phone number). The unique identification number is used to determine which
Controller can be accessed remotely on a serial line. The identification number for
each console needs to be entered in the “SYS PH#” field in the CPU sub menu. No two
systems can have the same number in the “SYS PH#” on the same network. If that field
is the same on more than one integrated access controller, race conditions will occur.
Therefore each console on a single network must have an individual number in the
“SYS PH#” field.
The identification numbers for the integrated access controllers cannot be entered
through a control station. This safeguard is provided to ensure a reliable connection
between a control station and an integrated access controller. Attempts to change an
identification number of a system remotely will be denied.

Interface Card

Network Priorities
All integrated access controllers on the wireless network have equal priorities. Because
of this equality, no Controller can interrupt a remote session between another Controller
and a control station. This is why the control station always initiates all communication
on the RTS network.

Intra-Network Communications
Integrated access controllers cannot communicate with each other. Communication on
the network is only between the control station and a single Controller. Since the
communications on the network of integrated access controllers is always initiated by
the control station, the Controller systems cannot communicate with each other.

The PC associated with integrated access controller #34 can engage any of the two
other units by using "AT" commands from the communications software used. If a
local VT-100 is active at any of the remote locations, the user will be logged off and the
master PC will control the system unit. When the master PC logs off, the local user
will be able log into the unit again. Connections at all units are done through the DB9
computer port.

Terminal Security
No user may log into any integrated access controller on the network without knowing
the individual password of each system.

External Alarm Cards

Introduction
The External Alarm card performs two alarm-notification functions. The "Switch/Act
On" (outbound) function allows the system to report internal alarms to external devices
such as buzzers, bells or lights. The "Sensor/Trig On" (inbound) function allows
externally generated alarms to be reported to the system through sensors that are located
on the card.
This chapter discusses the three External Alarm cards available for use with the
integrated access system: the 8401, 8402, and 8403. Only one External Alarm card may
reside in the integrated access system at a time. The 8401 and 8402 offer 4 and 3
inbound and outbound alarm circuits, respectively, and have a similar architecture.
They will be discussed together at the start of the chapter. The 8403, which offers
additional capabilities (28 inbound and 14 outbound), is discussed at the end of the
chapter.

8401 External Alarm Card
The 8401 External Alarm card supports four (4) outbound switches and four (4)
inbound sensors. The outbound switches are used to report internal alarms to external
devices by triggering form-C contact closures (120VAC - 0.5A), and the inbound
sensors are used to bring foreign alarm indications into the system. External alarms that
are reported by a sensor are listed in the alarm history file.

8402 External Alarm Card
The 8402 External Alarm card supports three (3) outbound switches and three (3)
inbound sensors. This card is similar to the 8401 except the fourth alarm port can only
be used as an outbound alarm to show that the system’s power unit has failed. This
card would be especially helpful when used in locations where loss of power to any of
the units would be a critical problem.
A -48VDC power source is required with this card. It may be provided by the 8905
Converter or from an external source.

IMPORTANT NOTE
To enable the reporting of alarms originating from sensors the SENSOR variable in the
Alarm Filters menu must be set to report (see “Filters” in Chapter 2C, “Basic
Operations”). From the system Main Menu, select Alarms, and choose Filters to
display a menu of alarm filters shown below. Use the arrow keys to highlight the first
column of the SENSOR line. Press  to display the options ignore, log, and
report. The option chosen here will act as the highest level option for all alarm card
sensors. If this variable is set to ignore, any alarm conditions from the alarm sensors
will be ignored, even if individual sensors are set to report at the alarm card.
Likewise, if this variable is set to log, all of the sensors on the alarm card that are set to
anything but ignore will be logged, but not reported. For this reason, it is crucial that
the SENSOR Alarm Filter be set to report.

8403 External Alarm Card
Introduction
The 8403 External Alarm Card supports 28 sensor inputs and 14 external device ports.
Of the 14 external device controls, 8 are Form C contacts (normally open or closed
based on user configuration), 4 are Form A contacts (normally open), and 2 are Form B
contacts (normally closed).
In addition, the card provides an FXS type telephone interface (RJ-11 jack, loop start
only, no ringer interface) and an on-board piezoelectric buzzer with either internally
generated and customer-selected alarm sounds or sounds transmitted by the network.
In the on-hook condition, ring signaling turns on the buzzer with either a locally stored
ringback pattern or a network-provided signal. In the off-hook conditions, voice output
of the transcoder is routed to the transformer. In an alarm condition, if the sound option
is enabled, a 3,000 Hz signal is routed to the buzzer.
All sensor inputs are current loop type (4-20 ma current detection). All sensors can be
either active (surge protection only) or optically isolated passive current detectors.
Active sensors can be powered by either the network battery (-48 VDC) or by the main
power supply (+12VDC).
The 8403 External Alarm Card is shown in Figure Alarm-3, emphasizing the positions
of switches and jumpers used to configure the card. All switches and jumpers should be
set prior to installation.

External Alarm Cards

SW. CTRL
This variable indicates the initial state of the switch. The possibilities are off (which
unconditionally turns the switch off), on (which unconditionally turns the switch on) or
act_on (which relies on the state of the switch). The default value is off.
As noted above, 12 of the switches are Form C (which may be either open or closed),
one is Form A (always open), and one is Form B (always closed).
In the event of system power failure, switch #1 can be used as a fail-safe switch to
activate a device that notifies the user. In order for this to occur, a jumper must be set
on jumper pair JP63. located towards the center of the card. The contact for switch #1
will close if the system loses power, establishing a circuit that can be used to power an
external warning device. The current source must be provided by the external device.

ACT ON
This parameter defines the condition that will cause the switch to trigger. The user can
program each alarm switch to trigger on info, minor, major, or crit alarms.
Alternatively, the switch trigger can also be assigned to a particular sensor. When
sensor is selected, SENSOR # allows the user to indicate the number of the sensor that
will trigger the alarm. The default value is major.

SENSOR #
When the ACT ON field is set to sensor, the user can input a value from 1 to 28,
indicating the number of the sensor that will trigger the switch. The default value is
n/a.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the State setting to stdby (standby) for
ports you are not using or have not yet configured. Set it to actv (active) for ports that
are ready for use. The default value is stdby.

Page 6-B-10

(10-97)

Reference Guide v3.6

External Alarm Cards

WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for
all ports on the same card to be assigned to the same WAN link, or to contiguous time
slots on a WAN link. The default value is none.

TS
The TS setting identifies the time slot on the WAN link to which this port is assigned.
Values range from 1-24 for T1 links and 1-31 for E1 links. Time slot 16 is not
available on E1 links that are programmed for cas or ccs signaling. For a display of the
available time slots, refer to your cross-connect map for the WAN link; see the System
Operations chapter for information about viewing cross-connect maps. The default
value is n/a.

MODE
The Mode setting should be determined by the type of equipment to which you are
connecting the port. All options use two-wire balanced connections. The fxs (Foreign
Exchange Station) option allows you to connect a telephone to the system.
The plar (private line automatic ringdown) option provides point-to-point unswitched
connections between two telephone sets. This configuration is usually not attached to
an exchange or switch; rather, it provides a “hot line” between two locations.

TYPE
The Type setting matches the signaling behavior of the FXS equipment and the remote
switch. The loop (Loop Start) option, which is used with POTS stations and simple
PBX trunks, is only available when the MODE setting is fxs. If the MODE setting is
plar, then the TYPE options are d3-m1, d4-m1, d3-m2, d4-m2, d3-m3, and d4-m3.
Caution: Before activating this port, verify the behavior expected by both the station
equipment and the remote central office equipment and ensure that you have the system
properly configured.

Rx TLP
The Receive Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are decoded to analog signals. To increase the
signal level, set the Rx TLP setting to a positive number (i.e., the larger the number, the
more gain is added). To decrease the signal level, set the Rx TLP setting to a negative
number (i.e., the more negative the number, the more the signal level is decreased). For
example, an incoming signal at -5 dBm can be increased to -3 dBm by setting Rx TLP
to +2 dB. Acceptable values range from -10.0 dB to +2.0 dB. The default value is 5.0.

(10-97)

Page 6-B-11

External Alarm Cards

Reference Guide v3.6

Tx TLP
The Transmit Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are received from the local analog port and
before they are encoded to digital PCM signals. To increase the signal level, set the Tx
TLP setting to a negative number (i.e., the more negative the number, the more gain is
added). To decrease the signal level, set the Tx TLP setting to a positive number (i.e.,
the more positive the number, the more the signal level is decreased). For example, an
incoming signal at -5 dBm can be increased to -2 dBm by setting Tx TLP to -3 dB.
Acceptable values range from -10.0 dB to +5.0 dB. The default value is +2.0.

CODING
The Coding setting sets the PCM companding method used for a port. In general, in the
T1/North American environment use µ-law coding. In the E1/International
environment, use a-inv (inverted A-law) or a-law coding; a-inv provides greater 1s
density than a-law. The coding default is determined by the type of card in the WAN
port you select. The default value is u-law (Note: On the system screens, "u" is used in
place of "µ" because of ASCII character limitations, but should be read as "mu-law.").

RINGBK
The ringback setting specifies whether a ringback tone is generated by the system and
sent towards the network. This option should be turned on when the network does not
provide an audible ringing tone to the calling party. The default value is off.

Onboard Buzzer
The 8403 alarm card contains an onboard buzzer for audible alarms. The buzzer can be
set to activate when a particular sensor signals an alarm condition. The buzzer volume
is set by a control dial marked "VOL," which can be adjusted using a small screwdriver.

US/Euro Jumper
The card may be set either to US or European configuration by moving a jumper
located on J64. Setting the jumper on the left two pins establishes US configuration.
On the right two pins, the jumper is configured for European voltage. This property
should match the configuration of your particular chassis, or the card will not operate
properly. The factory default is US position.

External Alarm Cards

Reference Guide v3.6

Voltage Control Switches
Switches S1 and S2 are used to control the voltage supplied to each group of active
sensors. When either of these switches are set to "SYS," the board supplies ±12vDC
system power to the sensor group specific to that Amphenol connector. When either of
the switches are set to "BAT," the board supplies telco power to the sensors in that
group.
The switches can be set individually (meaning one can be set to "SYS" and the other to
"BAT") but doing so will affect all 14 sensors in the respective group.
Switch S1 controls the sensors on the J3 (lower) connector, while Switch S2 controls
the sensors on the J4 (upper) connector.
The factory default for these switches is SYS.

Alarm Sensor Jumpers
Each sensor relates to a pair of jumpers on the board, which controls whether the sensor
is powered from the card (active mode) or from an external device (passive mode).
Passive mode provides 2500V isolation. Figure Alarm-6 displays these options.

sensors on the upper Amphenol connector (J4), while the lower group is associated with
the sensors on the lower Amphenol connector (J3).

Figure Alarm-7. Jumper Pair (Active Mode).
Note: All jumper pairs are set by factory default to active mode.
The default setting, as shown above, is active mode, in which the sensors are powered
by the card. This setting provides surge protection for the sensors.
To set the jumper pair to passive mode, users must remove both jumpers and then insert
a single jumper across the pair, as shown in Figure Alarm-8. The other jumper should
be stowed on one of the unused pins. (The pairs are set at an angle so that the extra
jumper will not fit across the outside pins.) This provides full isolation (to 2500V) for
the sensor.

E&M Card

Introduction
E&M cards manage the flow of voice traffic over the network. The E&M card
translates an analog signal to a digital bitstream at the local system and digital to analog
at the remote system. E&M signaling types I, II, IV and V are supported. Each card
controls four or eight units or channels. Normal E&M, Transmission Only and E&MR2
modes are supported. E&M cards can use voice-compression features of the ADPCM
server card.

8118 E&M Card
The 8118 is a 4-wire 600 Ω E&M/TO card with eight ports. This card has the same
extended range feature as the 8115. All normal E&M features are supported by this
card.

8119 E&M Card
The 8119 is a 4-wire 600 Ω E&M/TO card with eight ports. This card has an extended
TX TLP range (-17.5 to +14.5dB) to support dedicated 4-wire modem applications (this
is especially important for data transmission speeds of 19.2kbps or higher). This card
supports all normal E&M features.

UL Statement
OPERATION OF THIS INTERFACE IS LIMITED TO
INTRA-BUILDING CONNECTIONS ONLY

In addition to the cards shown above, whose operation will be discussed in this chapter,
the following discontinued models are supported by v3.6 software:

8104 E&M Card

E&M Card Settings
E&M voice cards require hardware and software setup. Each E&M card has four
switches (see Figure E&M-1), labeled S1 through S4, that control the type of E&M
signaling the card uses. All ports on a card must use the same type of signaling. Table
E&M-1 defines the switches.

NOTES
1.

Time slot 16 is not available if the port is assigned to an E1 WAN link
whose TS 16 is programmed for cas or ccs.

2.

The default is sl-1 if the mode selected is e&mR2 or R2mod.

3.

Extended settings for 8119 card are -17.5 to +14.5dB.

4.

The default is a-inv for E1 and µ-law for T1.

5.

Only the 8108 E&M card (which provides a two-wire interface) supports
the HYBRID parameter.

6.

Choosing a RATE other than 64K allows the user to select an ADPCM
slot.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the state setting to standby (stdby) for
ports you are not using or have not yet configured. Set it to active (actv) for ports that
are ready for use.

WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for
all ports on the same card to be assigned to the same WAN link, or to contiguous time
slots on a WAN link.

(10-97)

Page 7-A-5

E&M Card

Reference Guide v3.6

TS
The TS setting identifies the time slot on the WAN link to which this port is assigned.
Values range from 1-24 for T1 links and 1-31 for E1 links. Time slot 16 is not
available for E1 links that are programmed for cas or ccs signaling. For a display of the
available time slots, refer to your cross-connect map for the WAN link selected. (See
the System Operations chapter for information about viewing cross-connect maps.)

MODE
The Mode setting specifies if the port uses E&M (e&m) signaling or if it operates in
Transmission Only (to) mode. Use to mode if connecting to four-wire dedicated-line
modems that do not require E&M signaling. The signaling type for all eight ports on an
E&M card is selected by setting hardware switches S1 through S4 as described earlier
in this chapter. Select e&m if you want standard Type I, II IV or V signaling. Select
e&mR2 for symmetrical R2 signaling from either the digital or analog side. R2mod
provides modified R2 signaling for Motorola paging terminal equipment.

R2 TYPE
The R2 Type setting is reserved for future use. The value of n/a is unchangeable by the
user. Signaling type for all eight E&M ports on a card is selected by setting hardware
switches S1-S4 as described earlier. If the Mode selected for the port is e&mR2, then
the R2 Type will automatically default to sl-1.

Rx TLP
The Receive Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are decoded to analog signals. To increase the
signal level, set the Rx TLP setting to a positive number (i.e., the larger the number, the
more gain is added). To decrease the signal level, set the Rx TLP setting to a negative
number (i.e., the more negative the number, the more the signal level is decreased). For
example, an incoming signal at -5 dBm can be increased to -2 dBm by setting Rx TLP
to +3 dB. Acceptable values range from -16.3 dB to +7.5 dB.

Tx TLP
The Transmit Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are received from the local analog port and
before they are encoded to digital PCM signals. To increase the signal level, set the Tx
TLP setting to a negative number (i.e., the more negative the number, the more gain is
added). To decrease the signal level, set the Tx TLP setting to a positive number (i.e.,
the more positive the number, the more the signal level is decreased). For example, an
incoming signal at -5 dBm can be increased to -2 dBm by setting Tx TLP to -3 dB.
Acceptable values for the extended range 8119 E&M Card comprise -17.5 dB to +14.5
dB. Acceptable values for normal range E&M Cards comprise -16.5 dB to +7.3 dB.

(10-97)

Reference Guide v3.6

E&M Card

CODING
The Coding setting sets the PCM companding method used for a port. In general, in the
T1/North American environment use µ-law coding. In the E1/International
environment use a-law or a-inv (inverted A-law) coding; a-inv provides greater 1s
density than a-law. The coding default is determined by the type of card in the WAN
port you select.

TC CGA
The Trunk Conditioning during Carrier Group Alarm setting defines whether the E&M
port should be placed in idle or busy mode upon declaration of a Carrier Group Alarm
(CGA) on the WAN link to which the port is assigned. The TC CGA setting has no
effect on Transmission Only (to) circuits.
In most cases, you should set this parameter to busy. If a call is in progress when the
CGA alarm is received, the system will hold the call for two seconds, drop it and then
busy out the port to the attached PBX for the duration of the alarm. Once the alarm
clears, the system will automatically place the port back in idle mode thereby making it
available to the attached PBX.

LB
The LB setting sets the loopback for this circuit to off, digital (dgtl), or analog (anlg).
Figure E&M-3 illustrates the loopback options.

Reference Guide v3.6

PATTRN
The Pattern setting sets the outgoing test pattern, generated by the system, that is sent to
the selected port. A different pattern can be set for each port. The none option disables
sending a test pattern. The D-mW (Digital milliwatt) option sends a 1 kHz tone at 0.0
dBm. The setting of the Rx TLP setting affects the D-mW signal level. The quiet
option places a 600Ω termination on the line so that no analog signal is sent.

HYBRID
Available for the two-wire 8108 E&M card only, the Hybrid option assigns a three byte
pattern to define the adjustment for return loss (similar to Build Out Capacitors). The
default, set1, balances to the ideal termination of 900Ω @ 2.15mF. The other settings
are reserved for future use.

SIG CONV
The Signaling Conversion parameter allows the user to change the ABCD signaling bits
from CCITT (E1) to ANSI (T1) standards. This conversion is completed regardless of
the type of WAN aggregate (CSU/DSX or CEPT) to which it is attached.
The options are off (which means that ANSI signaling is used) and on (which converts
transmit signaling from ANSI to CCITT format according to the Interface Card
Conversion Table for E&M signaling, and also converts receive signaling from CCITT
to ANSI).

RATE
The Rate parameter allows the user to utilize the voice compression capabilities of the
ADPCM server card. If that card is not present in the system, changes cannot be made
to this setting. The 64K option (default) does not use ADPCM resources (it is the
normal operation rate for voice circuits).
ADPCM voice channels are assigned in pairs by designating two voice ports (E&M,
FXO or FXS) to the same WAN link and timeslot and selecting rate settings for the pair
that add up to 64kbps (i.e. [24K,1+40K,2],[ 32K,1+32K,2] and [40K,1+24K,2]). The
numeral 1 after the rate setting assigns that portion of the voice port pair to the odd side
of the ADPCM pair. The numeral 2 after the rate setting assigns that portion of the
voice port pair to the even side of the ADPCM pair.
For more information about voice port assignments to the ADPCM card, please consult
the ADPCM section of the manual.

ADPCM
The ADPCM parameter lets the user choose which ADPCM card to which this E&M
port is assigned. The default setting is n/a and only changes when a Rate smaller than
64k is selected (see above). The user is then allowed to select which ADPCM card to
use for the port (assignment is made by chassis slot number). The options are P1, P2
and P3.

The Test parameter shows if the port is in test mode or not. Inactive ports and ports
that are assigned to inactive WANs will show a test status of n/a. The test status
options for active ports are off and on.

Tx ABCD
The Transmit ABCD setting allows the user to either monitor the status of the ABCD
signaling bits being transmitted towards the network or set a specific ABCD pattern for
testing the transmit side of the circuit. The options for this field are mon (monitor) or
set. Choosing set will bring up a four digit field for you to input the ABCD pattern you
want to transmit. Any four digit combination of ones and zeros is acceptable for this
setting.

Rx ABCD
The Receive ABCD setting allows the user to either monitor the status of the ABCD
signaling bits being received from the network or set a specific ABCD pattern for
testing the receive side of the circuit.
The options for this field are mon (monitor) or set. Choosing set will bring up a four
digit field for you to input the ABCD pattern you want to receive. Any four digit
combination of ones and zeros is acceptable for this setting. The Rx ABCD bits cannot
be set in bus-connect systems and the only option is mon (monitor).

E-lead
The E-lead setting allows the user to either monitor or set the E lead. The options for
this field are mon (monitor) or set. Choosing set will bring up the options off (which
drops the E lead) and on (which raises the E lead).

TO USER
In cross-connect systems only, the To User parameter allows you to break the circuit
and send a test tone on the user side of the system. The options for this field are PCM,
300Hz, 1 kHz, 3 kHz and quiet. Selecting PCM means that you do not want to inject
a tone toward the user and that the PCM signal received from the network should
continue to be sent to the user port in the normal manner.
This parameter is not supported in bus-connect systems and will always appear as n/a.

TO NTWK
In cross-connect systems only, the To Network parameter allows you to break the
circuit and send a test tone on the network side of the system. The options for this field
are PCM, 300Hz, 1 kHz, 3 kHz and quiet. Selecting PCM means that you do not
want to inject a tone toward the network and that the PCM signal received from the user
port should continue to be sent to the network in the normal manner.

FXS Card

Introduction
Foreign Exchange Station Cards manage the flow of FXS voice traffic over the
network. The FXS card translates an analog signal to a digital bitstream at the local
system and digital to analog at the remote system.
All cards have a two-wire interface that supports Foreign Exchange Station, Private
Line Automatic Ringdown, Foreign Exchange Software Defined Network, Dial Pulse
Originating and Wink operations. FXS cards can use the voice-compression features of
the ADPCM server card.
FXS Cards also support digital to analog conversion as outlined in TR-TSY-000008 for

NOTES
1.

Time slot 16 is not available if the port is assigned to an E1 WAN link
whose TS 16 is programmed for cas or ccs.

2.

These options are only valid if the Mode selected is fxs or wink. If the
Mode is fxsdn, then the Type options are the same as above with the
addition of fgd and boa. If the Mode is plar, then the Type options are d3
or d4. If the Mode is dpo, then the Type setting will automatically default
to dpo.

3.

The default is a-inv for E1 and µ-law for T1. These values will change
depending upon the WAN link selected.

4.

Choosing RATE other than 64k allows the user to select an ADPCM slot.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the State setting to standby (stdby) for
ports you are not using or have not yet configured. Set it to active (actv) for ports that
are ready for use.

WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for
all ports on the same card to be assigned to the same WAN link, or to contiguous time
slots on a WAN link.

(10-97)

Page 7-B-3

FXS Card

Reference Guide v3.6

TS
The TS setting identifies the time slot on the WAN link to which this port is assigned.
Values range from 1-24 for T1 links and 1-31 for E1 links. Time slot 16 is not
available on E1 links that are programmed for cas or ccs signaling. For a display of the
available time slots, refer to your cross-connect map for the WAN link; see the
Operations chapter for information about viewing cross-connect maps.

MODE
The Mode setting should be determined by the type of equipment to which you are
connecting the port. All options use two-wire balanced connections. The fxs (Foreign
Exchange Station) option allows you to connect the system to a 2 way (both inbound
and outbound calls) PBX trunk or a key system trunk. The system requires a ringing
generator for this option. The fxsdn (Foreign Exchange Software Defined Network)
option provides access to new services offered by advanced networks from many major
carriers. The system requires a ringing generator for this option. The wink option uses
the same type of signaling as fxsdn and provides a 150MS delay, then a 200MS "wink"
back to the central office when the FXS card sees an off-hook condition from the
central office. The system requires a ringing generator for this option.
The plar (private line automatic ringdown) option provides point-to-point unswitched
connections between two telephone sets. This configuration is usually not attached to
an exchange or switch; rather it provides a “hot line” between two locations. The unit
requires a ringing generator for this option.
The dpo (Dial Pulse Originating) option allows the unit to attach to out-going one-way
trunks from a PBX, key system, or a telephone set. This option is very similar to the
fxs option; however, the system does not require a ringing generator.
The slc96 (Subscriber Loop Carrier 96) option allows the unit to attach to out-going
one-way trunks from a PBX, CENTREX, key system, or a telephone set to a SLC96
channel. The slc96 mode must be active on the WAN card selected.

TYPE
The Type setting matches the signaling behavior of the FXS equipment and the remote
switch. Use the loop (Loop Start) option with POTS stations and simple PBX trunks.
Use the lp-fd (Loop Start - Forward Disconnect) option with automated answering
equipment. Use the gs (Ground Start) option with two-way PBX trunks because it helps
to prevent glaring or call collisions. Use the gs-i (Ground Start Immediate) option for
equipment requiring fast-response time to the station or PBX. Use the gs-a (Ground
Start Automatic) option for equipment requiring fast-response time to the central office.
The selection you choose must match the behavior of both the station equipment and
the remote central office or PBX equipment.
If you selected the fxsdn mode, the choice of fgd is offered to make the circuit
compatible with Feature Group "D" high-speed modem services that require special
software. An additional choice of boa (bill on answer) sends a signal back to the office
when the customer answers the phone to start billing for the call.

Page 7-B-4

(10-97)

Reference Guide v3.6

FXS Card

If you selected the plar option for the Mode of this port, then the two options that are
supported under Type are d3 and d4 which meet the pre-1988 and post-1988
specifications for PLAR circuits. If you selected dpo as the Mode, the Type will
automatically default to dpo.
If slc96 is selected for Mode, the two options supported are sp (single party) and uvg
(universal voice grade).
Caution: Before activating this port, verify the behavior expected by both the station
equipment and the remote central office equipment and ensure that you have the system
properly configured.

Rx TLP
The Receive Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are decoded to analog signals. To increase the
signal level, set the Rx TLP setting to a positive number (i.e., the larger the number, the
more gain is added). To decrease the signal level, set the Rx TLP setting to a negative
number (i.e., the more negative the number, the more the signal level is decreased). For
example, an incoming signal at -5 dBm can be increased to -3 dBm by setting Rx TLP
to +2 dB. Acceptable values range from -10.0 dB to +2.0 dB.

Tx TLP
The Transmit Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are received from the local analog port and
before they are encoded to digital PCM signals. To increase the signal level, set the Tx
TLP setting to a negative number (i.e., the more negative the number, the more gain is
added). To decrease the signal level, set the Tx TLP setting to a positive number (i.e.,
the more positive the number, the more the signal level is decreased). For example, an
incoming signal at -5 dBm can be increased to -2 dBm by setting Tx TLP to -3 dB.
Acceptable values range from -10.0 dB to +5.0 dB.

CODING
The Coding setting sets the PCM companding method used for a port. In general, in the
T1/North American environment use µ-law coding. In the E1/International
environment use a-law or a-inv (inverted A-law) coding; a-inv provides greater 1s
density than a-law. The coding default is determined by the type of card in the WAN
port you select.

TC CGA
The Trunk Conditioning during Carrier Group Alarm setting defines whether the FXS
port should be placed in idle or busy mode upon declaration of a Carrier Group Alarm
(CGA) on the WAN link to which the port is assigned. In most cases, you should set
this parameter to busy. If a call is in progress when the CGA alarm is received, the
system will hold the call for two seconds, drop it and then busy out the port to the
attached PBX for the duration of the alarm. Once the alarm clears, the system will
automatically place the port back in idle mode thereby making it available to the
attached PBX.

PATTR
The Pattern setting sets the outgoing test pattern for this analog port. The pattern,
generated by the system, is sent to the selected port. A different pattern can be set for
each port. The none option disables sending a test pattern. The D-mW (Digital
milliwatt) option sends a 1 kHz tone at 0.0 dBm. The setting of the Rx TLP setting
affects the D-mW signal level. The quiet option places a 900Ω termination on the line
so that no analog signal is sent.

HYBRID
The Hybrid option assigns a three byte pattern to define the adjustment for return loss
(similar to Build Out Capacitors). The default, set1, balances to the ideal termination
of 900Ω @ 2.15mF in the case of the 8124 and 8128 cards 600Ω @ 2.15mF in the case
of the 8125 and 8129 cards. The other settings are reserved for future use.

RINGBK
The ringback setting specifies whether a ringback tone is generated by the system and
sent towards the network. The options are off and on. This option should be turned on
when the network service does not provide an audible ringing tone to the calling party.

FXS Card

SIG CONV
The Signaling Conversion parameter allows the user to change the ABCD signaling bits
from CCITT (E1) to ANSI (T1) standards. This conversion is completed regardless of
the type of WAN aggregate (CSU/DSX or CEPT) to which it is attached.
The options are off (which means that ANSI signaling is used) and on (which converts
transmit signaling from ANSI to CCITT format according to the Interface Card
Conversion Table for FXS signaling, and also converts receive signaling from CCITT
to ANSI).

RATE
The Rate parameter allows the user to utilize the voice compression capabilities of the
ADPCM server card. If that card is not present in the system, changes cannot be made
to this setting. The 64k option (default) does not use ADPCM resources (it is the
normal operation rate for voice circuits).
ADPCM voice channels are assigned in pairs by designating two voice ports (E&M,
FXO or FXS) to the same WAN link and timeslot and selecting rate settings for the pair
that add up to 64kbps (i.e. [24k,1+40k,2],[ 32k,1+32k,2] and [40k,1+24k,2]). The
numeral 1 after the rate setting assigns that portion of the voice port pair to the odd side
of the ADPCM pair. The numeral 2 after the rate setting assigns that portion of the
voice port pair to the even side of the ADPCM pair.
For more information about voice port assignments to the ADPCM card, please consult
the ADPCM section of the manual.

ADPCM
The ADPCM parameter lets the user choose which ADPCM card to place this E&M
port. The default setting is n/a and only changes when a Rate smaller than 64k is
selected (see above). The user is then allowed to select which ADPCM card to use for
the port (assignment is made by chassis slot number). The options are P1, P2 and P3.

The Test parameter shows if the port is in test mode or not. Inactive ports and ports
that are assigned to inactive WANs will show a test status of n/a. The test status
options for active ports are off and on.

Tx ABCD
The Transmit ABCD setting allows the user to either monitor the status of the ABCD
signaling bits being transmitted towards the network or set a specific ABCD pattern for
testing the transmit side of the circuit. The options for this field are mon (monitor) or
set. Choosing set will bring up a four digit field to input the ABCD pattern you want to
transmit. Any four digit combination of ones and zeros is acceptable for this setting.

Rx ABCD
The Receive ABCD setting allows the user to either monitor the status of the ABCD
signaling bits being received from the network or set a specific ABCD pattern for
testing the receive side of the circuit. The options for this field are mon (monitor) or
set. Choosing set will bring up a four digit field for you to input the ABCD pattern you
want to receive. Any four digit combination of ones and zeros is acceptable for this
setting. The Rx ABCD bits cannot be set in bus-connect systems and the only option is
mon (monitor).

T-R-CNTL
The Tip and Ring Control setting allows the user to either monitor (mon) or set (set) the
state of the Tip and Ring leads of an FXS port. Choosing set will bring up the
following options (b=battery, o=open, g=ground):

NOTES
1. Time slot 16 is not available if the port is assigned to an E1 WAN link whose TS 16
is programmed for cas or ccs.
2. These options are only valid if the Mode selected is fxo, or fxodn. If the mode is
dpt, then the Type options are dpt (default), R2 or i-R2. If the Mode is mrd, then
the Type setting will automatically default to mrd.
3. The default is a-inv for E1 and m-law for T1. These values will change depending
upon the WAN link selected.
4. These settings should be used with fxodn and dpt modes only.
5. Choosing a RATE other than 64k allows the user to select an ADPCM slot.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the State setting to standby (stdby) for
ports you are not using or have not yet configured. Set it to active (actv) for ports that
are ready for use.

WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for
all ports on the same card to be assigned to the same WAN link, or to contiguous time
slots on a WAN link.

TS
The TS setting identifies the time slot on the WAN link to which this port is assigned.
Values range from 1-24 for T1 links and 1-31 for E1 links. Time slot 16 is not
available on E1 links that are programmed for cas or ccs signaling. For a display of the
available time slots, refer to your cross-connect map for the WAN link. See the System
Operations chapter for information about defining cross-connect maps.

MODE
The Mode setting should be determined by the type of equipment to which you connect
the port. All options use two-wire balanced connections. The fxo (Foreign Exchange
Office) option allows you to connect the system to a 2 way PBX trunk (both inbound
and outbound calls) or a key system trunk. The fxodn (Foreign Exchange Office Defined Network) option provides access to new services offered by advanced networks
from many major carriers. The dpt (Dial Pulse Terminating) option allows the unit to
attach to incoming one-way trunks from a PBX, key system, or a telephone set. This
option is similar to the fxo option.

(10-97)

Page 7-C-3

FXO Card

Reference Guide v3.6

The mrd (manual ringdown) option provides point-to-point unswitched connections
between two telephone sets. This configuration is usually not attached to an exchange
or switch; rather it provides a “hot line” between two locations. The system requires
hardware changes and a ringing generator for this option (see instructions later in this
chapter).

SIGNAL
The Signal setting matches the signaling behavior of the FXO equipment and the
remote switch. Use the loop (Loop Start) option with telephone sets and simple PBX
trunks. Use the gs (Ground Start) option with two-way PBX trunks because it helps to
prevent glaring or call collisions. Use the lp-fd (Loop Start - Forward Disconnect)
option with automated answering equipment. The R2 option is provided for a CCITT
R2 interface. The selection you choose must match the behavior of the station
equipment and the remote central office or PBX equipment.
If you selected the dpt option for the Mode of any port, then the three options that are
supported under Type are dpt for standard Dial Pulse Termination signaling used in
North America, R2 for CCITT signaling used internationally and i-R2 (immediate R2)
which provides immediate seizure acknowledgment to the network. If you selected
mrd as the Mode, then Type will automatically default to mrd.
Caution: Before activating a port, verify the behavior expected by both the station
equipment and the remote central office equipment and ensure that you have the system
properly configured.

Rx TLP
The Receive Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are decoded to analog signals. To increase the
signal level, set the Rx TLP setting to a positive number (i.e., the larger the number, the
more gain is added). To decrease the signal level, set the Rx TLP setting to a negative
number (i.e., the more negative the number, the more the signal level is decreased). For
example, an incoming signal at -5 dBm can be increased to -3 dBm by setting Rx TLP
to +2 dB. Acceptable values range from -10.0 dB to +2.0 dB.

Tx TLP
The Transmit Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are received from the local analog port and
before they are encoded to digital PCM signals. To increase the signal level, set the Tx
TLP setting to a negative number (i.e., the more negative the number, the more gain is
added). To decrease the signal level, set the Tx TLP setting to a positive number (i.e.,
the more positive the number, the more the signal level is decreased). For example, an
incoming signal at -5 dBm can be increased to -2 dBm by setting Tx TLP to -3 dB.
Acceptable values range from -10.0 dB to +5.0 dB.

Reference Guide v3.6

FXO Card

CODING
The Coding setting sets the PCM companding method used for a port. In general, in the
T1/North American environment use m-law coding. In the E1/International
environment use a-law or a-inv (inverted A-law) coding;
a-inv provides greater 1s density than a-law. The coding default is determined by the
type of card in the WAN port you select.

TC CGA
The Trunk Conditioning during Carrier Group Alarm setting defines whether the FXO
port should be placed in idle or busy mode upon declaration of a Carrier Group Alarm
(CGA) on the WAN link to which the port is assigned. In most cases, you should set
this parameter to busy. If a call is in progress when the CGA alarm is received, the
system will hold the call for two seconds, drop it and then busy out the port to the
attached PBX for the duration of the alarm. Once the alarm clears, the system will
automatically place the port back in idle mode thereby making it available to the
attached PBX.

LB
The Loopback setting sets the loopback for this circuit to off, digital (dgtl), or analog
(anlg). Figure FXO-2 illustrates the loopback options.

PATTRN
The Pattern setting sets the outgoing test pattern for this analog port. The pattern,
generated by the system, is sent only to the currently selected port. The none option
disables sending a test pattern. The D-mW (Digital milliwatt) option sends a 1 kHz
tone at 0.0 dBm. The Rx TLP setting affects the D-mW signal level. The quiet option
places a 900Ω termination on the line so that no analog signal is sent.

HYBRID
The Hybrid option assigns a three byte pattern to define the adjustment for return loss
(similar to Build Out Capacitors). The default, set1, balances to the ideal termination
of 900Ω & 2.15mF, in the case of the 8134 and 8138 cards and to 600Ω @ 2.15mF, in
the case of the 8135 and 8139 cards. The other settings are reserved for future use.

WK DLY
The Wink Delay setting allows the user to set the wink delay time. The options are
units of 100 milliseconds. Settings are 1-99 (100 milliseconds to 9.9 seconds). The
Wink Delay and Wink options are applicable to CCITT systems for determining the
delay of the R2 state machine. They should only be used with modes fxodn and dpt
(R2 and i-R2).

WINK
The Wink setting allows the user to set the wink duration time. The options are units of
100 milliseconds. Settings are 1-99 (100 milliseconds to 9.9 seconds). This option is
only applicable with modes fxodn and dpt (R2 and i-R2).

SIG CONV
The Signaling Conversion parameter allows the user to change the ABCD signaling bits
from CCITT (E1) to ANSI (T1) standards. This conversion is completed regardless of
the type of WAN aggregate (CSU/DSX or CEPT) to which it is attached. The options
are off (which means that ANSI signaling is used) and on (which converts transmit
signaling from ANSI to CCITT format according to the Interface Card Conversion
Table for FXO signaling, and also converts receive signaling from CCITT to ANSI).

RATE
The Rate parameter allows the user to utilize the voice compression capabilities of the
ADPCM server card. If that card is not present in the system, changes cannot be made
to this setting. The 64k option (default) does not use ADPCM resources (it is the
normal operation rate for voice circuits).

Page 7-C-6

(10-97)

Reference Guide v3.6

FXO Card

ADPCM voice channels are assigned in pairs by designating two voice ports (E&M,
FXO or FXS) to the same WAN link and timeslot and selecting rate settings for the pair
that add up to 64kbps (i.e. [24k,1+40k,2],[ 32k,1+32k,2] and [40k,1+24k,2]). The
numeral 1 after the rate setting assigns that portion of the voice port pair to the odd side
of the ADPCM pair. The numeral 2 after the rate setting assigns that portion of the
voice port pair to the even side of the ADPCM pair.
For more information about voice port assignments to the ADPCM card, please consult
the ADPCM section of the manual.

ADPCM
The ADPCM parameter lets the user choose the ADPCM card on which to place this
FXO port. The default setting is n/a and only changes when a Rate smaller than 64k is
selected (see above). The user is then allowed to select which ADPCM card to use for
the port (assignment is made by chassis slot number). The options are P1, P2 and P3.

the A, B, C and D signaling bits of all FXO circuits on that card. In cross-connect
systems only, the test option also allows the user to apply test patterns and tones
towards the user and network sides of the system.

The Signaling Monitor feature works with the user card alarm system (see Basic
Operations section) to detect excessive signaling bit transitions. The system will
generate alarms if the number of transitions of any signaling bit in transmit or receive
direction for an active port exceeds 255 in any four second interval. The options are off
and on, and they are toggled using the G command in the Menu of Actions.

TEST
The Test Parameter shows if the port is in the test mode or not. Inactive ports and ports
that are assigned to inactive WANs will show a test status of n/a. The test status
options for active ports are off and on.

Tx ABCD
The Transmit ABCD setting allows the user to either monitor the status of the ABCD
signaling bits being transmitted towards the network or set a specific ABCD pattern for
testing the transmit side of the circuit. The options for this field are mon (monitor) or
set. Choosing set will bring up a four digit field for you to input the ABCD pattern you
want to transmit. Any four digit combination of ones and zeros is acceptable for this
setting.

Rx ABCD
The Receive ABCD setting allows the user to either monitor the status of the ABCD
signaling bits being received from the network or set a specific ABCD pattern for
testing the receive side of the circuit. The options for this field are mon (monitor) or
set. Choosing set will bring up a four digit field for you to input the ABCD pattern you
want to receive. Any four digit combination of ones and zeros is acceptable for this
setting. The Rx ABCD bits cannot be set in bus-connect systems and the only option is
mon (monitor).

T-R-CNTL
The Tip and Ring Control setting allows the user to either monitor (mon) or set (set) the
state of the Tip and Ring leads of an FXO port. Choosing set will bring up the
following options:
loop

the Tip and Ring leads are tied together

open

the Ring lead is not connected to either the Tip or to ground

TO USER
In cross-connect systems only, the To User parameter allows you to break the circuit
and send a test tone toward the user side of the system. The options for this field are
PCM, 300Hz, 1 kHz, 3 kHz and quiet. Selecting PCM means that you do not want to
inject a tone toward the user and that the PCM signal received from the network should
continue to be sent to the user port in the normal manner.
This parameter is not supported in bus-connect systems and will always appear as n/a.

card from its slot and connect shorting jumpers (ordered separately) vertically from #1
to #2 on both sets of pins next to the front edge of the card as shown in Figure FXO-4.
The numbers (#1 and #2) are not stenciled on the card, but they are shown here to
clarify the procedure.
Ports can be set individually for the mrd feature, but once set, remain in the mrd mode
until the jumpers are removed. This information is repeated in the Installation chapter.

FXS Coin Card

Introduction
This chapter provides connector pinout, configuration, and troubleshooting information
for the Foreign Exchange - Station (FXSC) Coin Voice Cards.
These cards manage the flow of FXS voice traffic over the network. Each card encodes
analog (voice, VF) signals to a digital bitstream at the local system for transmission
over a T1 or E1 network. It also decodes the digital signals to analog at the remote
system.
Each FXS coin card has two-wires interfaces that support FXS, Private Line Automatic
Ringdown (PLAR), Foreign Exchange Station-Defined Network (FXSDN), Dial-Pulse
Originating (DPO), and Wink-start operations. The FXS cards also can use the voicecompression features of an ADPCM card.

8149 FXS Coin Card
The 8149 FXS Coin Card has six ports and two wires, providing a 600-ohm terminating
impedance. The card consists of backplane interface circuitry, serial EEPROM for card
identification and adjustment parameters storage, metering pulse interface extension
between Coin Box Office (CO) and coin phone on the side of the coin phone, and six
voice line interface circuits. Each line interface circuit consists of a codec, a hybrid
circuit.

FXS Coin Card Settings
External Card Connectors and Pinouts
Refer to the Pinout Chapter in this manual.

Card Jumper/Switch Settings
The FXS Coin Card does not have any jumpers or switches on its motherboard.

Installing the FXS Coin Card
Install the FXS Coin Card in any user card slot. These slots are U1 to U8 on the twosided chassis and front-loading chassis with power supplies on top, or P1 to P4 and W1
to W4 on the front-loading chassis with power supplies on the side.

NOTES

(10-97)

1.

Choosing wan allows you to choose a WAN port (w1-1 through w4-2).

2.

Time slot 16 is not available if the port is assigned to an E1 WAN link whose time
slot 16 is programmed for CAS or CCS.

Page 7-D-3

FXS Coin Card

Reference Guide v3.6

3.

The default is a-inv for E1 and u-law for T1. These values will change depending
upon the WAN link selected.

4.

The default (set1) is the only active option. It balances to the ideal termination of
600 ohms + 2.15 uF. The other settings are reserved for future use.

5.

Choosing a Rate other than 64K allows you to select an ADPCM.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the State setting to stdby (standby) for
ports that are not to be used or that have not yet been configured. Set it to actv (active)
for ports that are ready for use.

WAN
The WAN setting identifies the WAN link assigned to this port. If you choose wan, you
also must select the desired port (w1-1 through w4-2) of a WAN card for transmission
over a T1 or E1 link. This can be an ATM or FRS card, which resides in chassis slot
P1, P2, or P3. You must then choose a logical port on that card. The user option is not
used.
It is not necessary to assign all ports of the same FXS coin card to the same WAN link,
or to contiguous time slots on a WAN link.

TS
The TS setting identifies the time slot on the WAN link to which this port is assigned.
Values range from 1 to 24 for T1 links and 1 to 31 for E1 links. Time slot 16 is not
available on E1 links that are programmed for cas or ccs signaling. For a display of the
available time slots, refer to the cross-connect map for the WAN link; see the
Operations chapter for information about viewing cross-connect maps.

MODE
The Mode setting should be determined by the type of equipment to which the user is
connecting the port. All options use two-wire balanced connections. The fxsc (Foreign
Exchange Station-Coin) option allows users to connect the system to a two-way (both
inbound and outbound calls) PBX trunk or a key system trunk.

TYPE
The Type setting matches the signaling behavior of the FXSC equipment and the
remote switch. These settings are hf-a1 (high frequency - 12kHz), hf-a2 (high
frequency - 16kHz), hf-cb (high frequency-clear back), rb-a1 (reverse battery-answer
1), rb-a2 (reverse battery-answer 2), and rb-cb (reverse battery-clear back).

Page 7-D-4

(10-97)

Reference Guide v3.6

FXS Coin Card

Rx TLP
The Receive Transmission Level Point (TLP) setting controls the amount of gain or loss
added to the incoming signal after it is decoded to analog. To increase the signal level,
set the Rx TLP setting to a positive value (i.e., the larger the number, the more gain is
added). To decrease the signal level, set the Rx TLP setting to a negative value (i.e., the
more negative the number, the more the signal level is decreased). For example, an
incoming signal at -5 dBm can be increased to -3 dBm by setting Rx TLP to +2 dB.
The Rx TLP range is -10.0 dB to +2.0 dB.

Tx TLP
The Transmit TLP setting controls the amount of gain or loss added to a voice signal
from the CPE before it is encoded to digital PCM. To increase the signal level, set the
Tx TLP setting to a negative value (i.e., the more negative the number, the more gain is
added). To decrease the signal level, set the Tx TLP setting to a positive value (i.e., the
more positive the number, the more the signal level is decreased). For example, an
incoming signal at -5 dBm can be increased to -2 dBm by setting the Tx TLP to -3 dB.
The Tx TLP range is -10.0 dB to +5.0 dB.

CODING
The Coding setting sets the PCM companding method used for a port. Generally, the
North American T1 environment uses m-law coding, and the International E1
environment uses a-law or a-inv (inverted A-law) coding. The a-inv setting provides a
higher ones density than a-law. The default coding setting is determined by the type of
associated WAN card.

TC CGA
The Trunk Conditioning during Carrier Group Alarm setting defines whether the FXS
port should be forced idle or busy upon declaration of a Carrier Group Alarm (CGA) on
the WAN link to which the port is assigned. In most cases, you should set this
parameter to busy. If a call is in progress when the CGA alarm is received, the system
will hold the call for two seconds, drop it, and then busy out the port to the attached
PBX for the duration of the alarm. Once the alarm clears, the system will automatically
place the port back in the idle mode, making it available to the PBX.

LB
The Loopback field lets you loop the port back toward the network and far end. The
dgtl (digital) loopback sends the incoming digital DS0 signal back to the far end
without decoding it. The anlg (analog) loopback sends the decoded analog signal back
to the far end after decoding and then re-encoding it. Figure FXSC-2 shows the
loopback options, which allow you to test and troubleshoot the FXS card. To disable a
loopback, set this field to off.

PATTRN
The Pattern field selects an outgoing test pattern for the current card port. The test
pattern is generated by the system and sent to the selected port. You can select a
different pattern for each port. The none option disables the test pattern. The D-mW
(Digital milliwatt) option sends a 1 kHz tone at 0.0 dBm. The setting of the Rx TLP
setting affects the D-mW signal level. The quiet option places a 600-ohm termination
on the line so that no analog signal is sent (idle mode).

HYBRID
The Hybrid option assigns a three byte pattern to define the adjustment for return loss
(similar to Build Out Capacitors). The default, set1, balances to the ideal termination of
600 ohms + 2.15 uF. The other settings are reserved for future use.

RINGBK
The ringback setting specifies whether a ringback tone is generated by the system and
sent towards the network. Turn this option off when the network service does not
provide an audible ringing tone to the calling party.

RATE
The Rate parameter allows you to use the voice compression capabilities of an ADPCM
card. If that card is not present in the system, the Rate stays at 64k and cannot be
changed. The 64k option is the normal encoding/decoding rate for voice circuits.

Page 7-D-6

(10-97)

Reference Guide v3.6

FXS Coin Card

ADPCM voice channels are assigned in pairs by designating two voice ports (E&M,
FXO, or FXS) to the same WAN link and timeslot, and selecting rate settings for the
pair that add up to 64 kbps. The following combinations are possible:
24K,1+40K,2 (24 kb coding on one side of the time slot and 40 kb coding on the other
side of the same time slot)
32K,1+32K,2 (32 kb encoding on each side of a time slot)
40K,1+24K,2 (40 kb coding on one side of the time slot and 24 kb coding on the other
side)
Number 1 after the rate setting assigns that portion of the voice port pair to the odd side
of the ADPCM pair. Number 2 after the rate setting assigns that portion of the voice
port pair to the even side of the ADPCM pair.
For more information about voice port assignments to an ADPCM card, please consult
Chapter 7A of this guide.
The number 1 after the rate setting assigns that portion of the voice port pair to the odd
side of the ADPCM pair. The number 2 after the rate setting assigns that portion of the
voice port pair to the even side of the ADPCM pair.
For more information about voice port assignments to the ADPCM card, please consult
the ADPCM section of the manual.

ADPCM
The ADPCM parameter lets the user choose which ADPCM card to place this E&M
port. The default setting is n/a and only changes when a Rate smaller than 64k is
selected (see above). The user is then allowed to select which ADPCM card to use for
the port (this assignment is made by chassis slot number). The options are slots P1, P2,
and P3.

Test Screen
The Test option facilitates testing and maintenance by allowing you to monitor and set
the status of the analog interface leads, and to monitor or set the value of the A, B, C,
and D signaling bits of all FXS circuits on that card. In cross-connect systems, the test
option also allows you to apply test patterns and tones towards the user and network
sides of the system.
Figure FXSC-3 shows the FXS Coin Card Test Screen parameters, Table FXSC-3 lists
some actions you can perform from this screen, and Table FXSC-4 shows the settings
for each parameter.

SIG MON
The Signaling Monitor feature works with the user card alarm system (see Chapter 3-A)
to detect excessive signaling bit transitions. The system will generate alarms if the
number of transitions of any signaling bit in transmit or receive direction for an active
port exceeds 255 in any four second interval. The options are off and on, and they are
toggled by pressing “g” (siGmon command) in the Test Screen.

TEST
The Test parameter shows if the port is in test mode or not. Inactive ports and ports that
are assigned to inactive WANs will show a test status of n/a. The test status options for
active ports are off and on.

Tx ABCD
The Transmit ABCD setting allows you to either monitor the status of the ABCD
signaling bits being transmitted towards the network or set a specific ABCD pattern for
testing the transmit side of the circuit. The option for this field is mon (monitor).

Rx ABCD
The Receive ABCD setting allows the user to either monitor the status of the ABCD
signaling bits being received from the network or set a specific ABCD pattern for
testing the receive side of the circuit. The option for this field is mon (monitor).

T-R-CNTL
The Tip and Ring Control setting allows you to mon (monitor) the state of the Tip and
Ring leads of an FXS port:
RbTo (-48V is applied to the Ring lead and the Tip lead is open)
TbRo (-48V is applied to the Tip lead and the Ring lead is open)
RbTg (-48V is applied to the Ring lead and the Tip lead is grounded)
TbRg (-48V is applied to the Tip lead and the Ring lead is grounded)

TO USER
In cross-connect systems only, the To User parameter allows you to break the circuit
and send a test tone on the user side of the system. The options for this field are PCM,
300Hz, 1kHz, 3kHz, and quiet. Choose PCM if you do not want to inject a tone
toward the CPE. In this case, the PCM signal received from the network is still sent to
the CPE in the normal manner.

signaling bits that are received from the network. If RX ABCD in the top half of the
screen is changed via the set function mentioned above, and the settings are saved by
the Save command in the Menu of Actions, the new bit pattern chosen will be reflected
here.

T-R-CNTL
The Tip and Ring Control informational field shows the current status of the Tip and
Ring leads of the FXS port from the perspective of the system. The possible values are
as follows
(b = battery, o = open, g = ground):
RbTo (-48V is applied to the Ring lead and the Tip lead is open)
TbRo (-48V is applied to the Tip lead and the Ring lead is open)
RbTg (-48V is applied to the Ring lead and the Tip lead is grounded)
TbRg (-48V is applied to the Tip lead and the Ring lead is grounded)
ring (the ringing voltage is applied between Tip and Ring)

T-R-STAT
The Tip and Ring Status informational field describes what the attached device is doing
with the Tip and Ring leads of the FXS port. The possible values are:
loop (attached device is connecting Tip and Ring together)
rgnd (the Ring lead is grounded by the attached device)

FXO Coin Card

Introduction
The Foreign Exchange Office Coin Card manages the flow of FXOC voice traffic over
the network. The FXOC card translates an analog signal to a digital bitstream at the
local system and digital to analog at the remote system. All FXOC cards have a twowire interface and support Foreign Exchange Office functions, Manual Ringdown,
Foreign Exchange Defined Network and Dial Pulse Terminating operations. FXOC
cards can use the voice-compression features of the ADPCM resource card.

8159 FXO Coin Card
The 8159 FXO Coin Card has eight ports and two wires, providing a 600-ohm
terminating impedance. The card consists of backplane interface circuitry, serial
EEPROM for card identification and adjustment parameters storage, metering pulse
interface extension between Coin Box Office (CO) and coin phone on the CO side, and
eight voice line interface circuits. Each line interface circuit consists of a codec, a
hybrid circuit (2 to 4 wire converter), line feed circuitry and relays to control modes of
operation.

FXO Coin Card Settings
External Card Connectors and Pinouts
Refer to the Pinout Chapter in this manual.

Card Jumper/Switch Settings
Setting or resetting jumpers is necessary for conversion of individual ports on the
FXOC card to mrd (Manual Ringdown) mode. To make this conversion, remove the
FXOC card from its slot and connect shorting jumpers (ordered separately) vertically
from #1 to #2 on both sets of pins next to the front edge of the card as shown in Figure
FXOC-1. The numbers (#1 and #2) are not stenciled on the card, but they are
shown here to clarify the procedure.
Ports can be set individually for the mrd feature, but once set, remain in the mrd mode
until the jumpers are removed. This information is repeated in the Installation chapter.

1.

Choosing wan allows you to choose a WAN port (w1-1 through w4-2). The user
option is not used.

2.

Time slot 16 is not available if the port is assigned to an E1 WAN link whose TS
16 is programmed for cas or ccs.

3.

The default is hf-a1.

4.

The default is a-inv for E1 and m-law for T1. These values will change depending
upon the WAN link selected.

(10-97)

Reference Guide v3.6

FXO Coin Card

5.

The default, set1, is the only active option. It balances to the ideal termination of
600 ohms +2.15uF. The other settings are reserved for future use.

6.

Choosing a Rate other than 64K allows you to select an ADPCM slot.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the State setting to stdby (standby) for
ports you are not using or have not yet configured. Set it to actv (active) for ports that
are ready for use.

WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for
all ports on the same card to be assigned to the same WAN link, or to contiguous time
slots on a WAN link.

TS
The TS setting identifies the time slot on the WAN link to which this port is assigned.
Values range from 1-24 for T1 links and 1-31 for E1 links. Time slot 16 is not available
on E1 links that are programmed for cas or ccs signaling. For a display of the available
time slots, refer to your cross-connect map for the WAN link.

MODE
The Mode setting should be determined by the type of equipment to which you connect
the port. All options use two-wire balanced connections. The fxoc (Foreign Exchange
Office Coin) option allows you to connect the system to a 2 way PBX trunk (both
inbound and outbound calls) or a key system trunk. The fxodn (Foreign Exchange
Office - Defined Network) option provides access to new services offered by advanced
networks from many major carriers. The dpt (Dial Pulse Terminating) option allows
the unit to attach to incoming one-way trunks from a PBX, key system, or a telephone
set. This option is similar to the fxoc option.
The mrd (manual ringdown) option provides point-to-point unswitched connections
between two telephone sets. This configuration is usually not attached to an exchange
or switch; rather it provides a “hot line” between two locations. The system requires
hardware changes and a ringing generator for this option (see instructions later in this
chapter).

SIGNAL
The Signal setting matches the signaling behavior of the FXOC equipment and the
remote switch. These settings are hf-a1(high frequency - 12kHz), hf-a2 (high frequency
- 16kHz), hf-cb (high frequency-clear back), rb-a1 (reverse battery-answer 1), rb-a2
(reverse battery-answer 2), and rb-cb (reverse battery-clear back).

(10-97)

Page 7-E-5

FXO Coin Card

Reference Guide v3.6

Rx TLP
The Receive Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are decoded to analog signals. To increase the
signal level, set the Rx TLP setting to a positive number (i.e., the larger the number, the
more gain is added). To decrease the signal level, set the Rx TLP setting to a negative
number (i.e., the more negative the number, the more the signal level is decreased). For
example, an incoming signal at -5 dBm can be increased to -3 dBm by setting Rx TLP
to +2 dB. Acceptable values range from -10.0 dB to +2.0 dB.

Tx TLP
The Transmit Transmission Level Point setting controls the amount of gain or
attenuation added to signals after they are received from the local analog port and
before they are encoded to digital PCM signals. To increase the signal level, set the Tx
TLP setting to a negative number (i.e., the more negative the number, the more gain is
added). To decrease the signal level, set the Tx TLP setting to a positive number (i.e.,
the more positive the number, the more the signal level is decreased). For example, an
incoming signal at -5 dBm can be increased to -2 dBm by setting Tx TLP to -3 dB.
Acceptable values range from -10.0 dB to +5.0 dB.

CODING
The Coding setting sets the PCM companding method used for a port. Generally, the
North American T1 environment uses m-law coding. The International E1 environment
uses a-law or a-inv (inverted A-law) coding, and a-inv provides a higher ones density
than a-law. The coding default is determined by the type of card in the WAN port you
select.

TC CGA
The Trunk Conditioning during Carrier Group Alarm setting defines whether the FXOC
port should be placed in idle or busy mode upon declaration of a Carrier Group Alarm
(CGA) on the WAN link to which the port is assigned. In most cases, you should set
this parameter to busy. If a call is in progress when the CGA alarm is received, the
system will hold the call for two seconds, drop it and then busy out the port to the
attached PBX for the duration of the alarm. Once the alarm clears, the system will
automatically place the port back in idle mode thereby making it available to the
attached PBX.

LB
The Loopback setting sets the loopback for this circuit to off, dgtl (digital), or anlg
(analog). Figure FXOC-3 illustrates the loopback options.

PATTRN
The Pattern setting sets the outgoing test pattern for this analog port. The pattern,
generated by the system, is sent only to the currently selected port. The none option
disables sending a test pattern. The D-mW (Digital milliwatt) option sends a 1 kHz
tone at 0.0 dBm. The Rx TLP setting affects the D-mW signal level. The quiet option
places a 900Ω termination on the line so that no analog signal is sent.

HYBRID
The Hybrid option assigns a three byte pattern to define the adjustment for return loss
(similar to Build Out Capacitors). The default, set1, balances to the ideal termination
of 900Ω @ 2.15mF, in the case of the 8134 and 8138 cards and to 600Ω @ 2.15mF, in
the case of the 8135 and 8139 cards. The other settings are reserved for future use.

RATE
The Rate parameter allows you to utilize the voice compression capabilities of the
ADPCM resource card. If that card is not present in the system, changes cannot be
made to this setting. The 64K option (default) does not use ADPCM resources (it is the
normal operation rate for voice circuits).
ADPCM voice channels are assigned in pairs by designating two voice ports (E&M,
FXOC or FXS) to the same WAN link and timeslot and selecting rate settings for the
pair that add up to 64Kbps (i.e., [24K,1+40K,2],[ 32K,1+32K,2] and [40K,1+24K,2]).
The numeral 1 after the rate setting assigns that portion of the voice port pair to the odd
side of the ADPCM pair. The numeral 2 after the rate setting assigns that portion of the
voice port pair to the even side of the ADPCM pair.

(10-97)

Page 7-E-7

FXO Coin Card

Reference Guide v3.6

For more information about voice port assignments to the ADPCM card, please consult
the ADPCM section of the manual.

ADPCM
The ADPCM parameter lets you choose the ADPCM card on which to place this FXO
port. The default setting is n/a and only changes when a Rate smaller than 64k is
selected (see above). You can then select which ADPCM card to use for the port
(assignment is made by chassis slot number). The options are P1, P2, and P3.

Test Screen
The Test option facilitates testing and maintenance by allowing the user to monitor and
set the status of the analog interface leads as well as monitoring and setting the value of
the A, B, C and D signaling bits of all FXOC circuits on that card. In cross-connect
systems only, the test option also allows the user to apply test patterns and tones
towards the user and network sides of the system.
Figure FXOC-4 shows the FXO Coin Card Test parameters and Table FXOC-4 shows
the settings for each.

SIG MON
The Signaling Monitor feature works with the user card alarm system (see Basic
Operations section) to detect excessive signaling bit transitions. The system will
generate alarms if the number of transitions of any signaling bit in transmit or receive
direction for an active port exceeds 255 in any four second interval. The options are off
and on, and they are toggled using the G command in the Menu of Actions.

TEST
The Test Parameter shows if the port is in the test mode or not. Inactive ports and ports
that are assigned to inactive WANs will show a test status of n/a. The test status
options for active ports are off and on.

Tx ABCD
The Transmit ABCD setting allows you to either monitor the status of the ABCD
signaling bits being transmitted towards the network or set a specific ABCD pattern for
testing the transmit side of the circuit. The option for this field is mon (monitor).

Rx ABCD
The Receive ABCD setting allows you to either monitor the status of the ABCD
signaling bits being received from the network or set a specific ABCD pattern for
testing the receive side of the circuit. The option for this field is mon (monitor). The
Rx ABCD bits cannot be set in bus-connect systems and the only option is mon
(monitor).

T-R-CNTL
The Tip and Ring Control setting allows you to only monitor mon the state of the Tip
and Ring leads of an FXO port.

TO USER
In cross-connect systems only, the To User parameter allows you to break the circuit
and send a test tone toward the user side of the system. The options for this field are
PCM, 300Hz, 1 kHz, 3 kHz and quiet. Selecting PCM means that you do not want to
inject a tone toward the user and that the PCM signal received from the network should
continue to be sent to the user port in the normal manner.
This parameter is not supported in bus-connect systems and will always appear as n/a.

TO NTWK
In cross-connect systems only, the To Network parameter allows you to break the
circuit and send a test tone toward the network side of the system. The options for this
field are PCM, 300Hz, 1 kHz, 3 kHz and quiet. Selecting PCM means that you do
not want to inject a tone toward the network and that the PCM signal received from the
user port should continue to be sent to the network in the normal manner.
This parameter is not supported in bus-connect systems and will always appear as n/a.

Tx ABCD
The Transmit ABCD setting allows you to either monitor the status of the ABCD
signaling bits being transmitted towards the network or set a specific ABCD pattern for
testing the transmit side of the circuit. The options for this field are mon (monitor) or
set. Choosing set will bring up a four digit field for you to input the ABCD pattern you
want to transmit. Any four digit combination of ones and zeros is acceptable for this
setting.

HSU Card

Introduction
HSU cards allow you to connect high speed data terminal equipment (DTE) and data
communications equipment (DCE) to WAN links, server cards (ADPCM) or another
HSU card.

8202 High-Speed Unit Card
The 8202 HSU Card supports two RS530/RS449 data ports. It can also support V.35
and RS232 data through the use of the appropriate Personality Module (See the end of
this chapter for instructions on the personality modules).

8203 High Speed Unit Card
The 8203 HSU Card supports two ANSI/EIA/TIA-530 ports. Each of the two ports can
be configured to operate as DCE or DTE at data rates from 56 Kbps to 2.048 Mbps.

8212 High-Speed Unit Card
The 8212 HSU Card supports two V.35 data ports.

8214 High-Speed Unit Card V.35 Trunk / User
The 8214 HSU Card supports two V.35 data ports. Each of the two ports can be
configured to operate as DCE or DTE at data rates from 56 Kbps to 2.048 Mbps in
56Kbps or 64 Kbps steps.

8215 High-Speed Unit Card
The 8215 HSU Card supports four RS530 or V.35 data ports. The selection of RS530
or V.35 is made on a port-by-port basis using on-board switches (see Installation
chapter). It can also support RS232 data at 56kbps through the use of the 1252 and
1253 Personality Modules and 1240 cable adapter (See the end of this chapter for
instructions on using the personality modules).
Caution: When using modes without B8ZS and Pulse set to transparent, HSU card
ports assigned to multirate circuits greater than or equal to 4x64kbps must have
DTE connected to the port prior to activation. Failure to attach DTE will cause a
false carrier alarm. Using Alternate Channel AMI will avoid this problem.

HSU Card Settings
Figure HSU-1 shows the high-speed data unit (HSU) screen. Table HSU-1 lists the
settings controlled on this screen along with their possible and default values.

options are off and on.

4.

This is an information-only field, there are no user selections.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy time slots on a WAN link. Set the State setting to standby (stdby) for
ports you are not using or have not yet configured. Set it to active (actv) for ports that
are ready for use. The control leads assume the status shown in Table HSU-2 for the
different states.

WAN/SRV
The WAN/SERVER setting identifies the card to which the output of this port is
directed. If wan is chosen, the data from this port will be directed to a WAN port (the
options are w1-1 through w4-2).

MODE
This parameter allows you to identify how the HSU port appears to the device on the
other end of the circuit. The dce option causes the port to be recognized as a DCE (data
circuit-terminating equipment) device. The dte option causes the port to be recognized
as a DTE (data terminal equipment) device.
Note that the choices appearing for some of the parameters that follow will depend on
whether you choose dce or dte as the Mode. Those parameters and their available
settings are described below.

TS
The TS (time slot) setting identifies the time slots on the WAN link when wan is
selected in the previous setting. Unlike the other user cards, the HSU card can use
many time slots on a single WAN port to create a super-rate circuit for an individual
HSU port. One or all DS0s on a single T1/E1 link can be assembled for use by the HSU
port according to the speed requirements of the DTE.
Values range from 1-24 for T1 links and 1-31 for E1 links. Time slot 16 is not
available for E1 links that are programmed for cas or ccs signaling. Figure HSU-4
shows the display when table is selected. Using the space bar to select and deselect the
time slot, this example shows time slots 11-16 on WAN 1-1 assigned to this port. Time
slot assignments do not need to be contiguous.

Figure HSU-4. HSU Table Option

RATE
The Rate setting allows you to select the bandwidth for all time slots assigned to this
port. Choices are 56k or 64k. This choice, multiplied by the number of time slots
assigned to the port define the port speed.

Tx CLOCK
The Transmit Clock setting identifies the clock source for the transmit data (SD)
stream. The internal (int) option requires the DTE to synchronize its transmitted data
with the clock on the SCT leads. The external (ext) option requires the DTE to
synchronize the transmitted data with the clock on the SCTE leads.
Use the external option with a long V.35 cable to make sure the data and clock are in
phase when they arrive at the system. The DTE must loop back the clock on the SCT
leads to the SCTE leads. If the external option is selected and the system does not
detect a clock on the SCTE leads, then the HSU automatically generates a clock
internally. If this clock is not synchronized with the data, then the CLK PLRTY can be
changed to attempt to synchronize.

HSU Card

CLOCK PLRTY
The Clock Polarity setting provides another way to compensate for long V.35 cables in
those cases where the DTE equipment does not provide SCTE. When using inverted
(inv) mode, the relationship between clock and data is altered to compensate for the
long cable distance that the signals must travel. The other option, normal (norm),
means that the relationship between clock and data is left unchanged. If you use
inverted (inv) Clock Polarity, set the Transmit Clock (Tx CLK) to (int).

DATA PLRTY
The Data Polarity option allows you to invert all bits in the transmitted data stream.
The default, normal (norm), means that the data is left untouched while inverted (inv)
means that all bits will be inverted. This can be helpful in ensuring ones density on T1
links when the data is known to contain long strings of zeros. By inverting those zeros,
you reduce the likelihood that the composite T1 stream will not meet the ones density
requirement. Both systems must have this parameter set to the same option.

CTS
The Clear To Send setting controls when a CTS signal is sent. Some DTE equipment
must receive a CTS signal before transmitting data. Change the CTS setting to
permanent (perm) to make the CTS signal always High or on. The remote-local
(rlocal) option allows RTS to control both the CTS of the local equipment and RLSD
of the remote DTE equipment.
Set the CTS setting to ignore (ignor) to make the CTS signal always Low or off. The
CTS signal is always High (enabled) when the port is in standby state, regardless of the
CTS setting. Set the CTS setting to local (locl) to make the CTS signal follow the RTS
signal from the local DTE.

CTS DELAY
The Clear To Send Delay setting delays the changes in the CTS signal in local mode.
Enter the value that you need in milliseconds. The options are 0, 30, 60, and 100 ms.
If you do not know what value you need, start with 0 ms and increase the value if you
experience problems. The CTS setting must be set to local before the CTS Delay setting
has any effect.

LB
The dte option loops back data to the local DTE device. It tests the local cabling and
most of the circuitry in the HSU card (see Figure HSU-5).

LB GEN MODE
The Loopback Generation Mode setting defines the type of in-band loop-up and loopdown codes that will be sent to the remote equipment. Three industry-standard codes
are supported: dds, which will send a DDS-compatible latching loopback code in each
of the DS0s that make up the circuit; v.54, which is compatible with CCITT V.54
standard and ft1, which is compatible with ANSI Fractional T1 standard. The final
option, perf (performance monitoring), activates an 8kbps performance monitoring
channel (isolated from the total bandwidth of the circuit) that collects end-to-end
performance statistics from a local HSU card to a remote HSU card. (See Performance
Monitoring section later in this chapter.)

LB GEN
If you selected v.54, ft1 or perf in the previous setting, the Loopback Generation
setting allows you to send a loop-up command (on) or a loop-down command (off). If
you selected dds as the Loopback Generation Mode, then this setting allows you to
define the type of DDS loopback that you wish to generate. The four options are ocu
(Office Channel Unit), dsu (Data Service Unit), csu (Channel Service Unit) and ds0 (a
full 64kbps loopback). Figures HSU-7, -8, and -9 illustrate where the loopbacks will
take place. You can also turn all DDS remote loopbacks off.
Loop-up or loop-down commands cannot be implemented for two ports on the same
card simultaneously. The user must finish all loopback operations on one port before
attempting to perform any loopback operations on another port.

LB DET
Depending on the selection you made for Loopback Generation Mode above, the HSU
port will respond to any of the loopback codes generated by a remote system. The
Loopback Detection setting does not affect local loopback commands from the local
control terminal.
The off option causes the system to ignore remote loopback commands. The on option
causes the system to monitor ports for loopback commands from the remote equipment,
but only in the format selected in LB GEN MODE. If the system detects a loopback
code, it loops the data back until the remote equipment releases the loopback. The with
time-out (w/to) option is the same as the on option, except that after ten minutes the
system automatically releases loopbacks initiated by the remote equipment.

EER
The Excessive Error Rate parameter is only available on the 8213 HSU card. This
option selects the error rate at which an alarm is declared. If the number of errors
exceeds the value set by this option an "E" will be placed in the Status Column of the
Performance Monitoring screen. The options are 10e-4 through 10e-9 or none.

On the model 8215 HSU only, selection of BERT pattern ds0 will display another set of
BERT patterns. Additional nonlatching loopback patterns are ff (1111-0000), 7e (01111110), 32 (0011-0010), 40 (0100-0000), ocu-a (ocu-alternating byte), csu-a (csualternating byte), dsu-a (dsu-alternating byte), csu1a (csu - one repeater - alternating
byte) and csu2a (csu - two repeaters - alternating byte). The results of the alternating
patterns (ocu-a, csu-a, dsu-a, csu1a and csu2a) will display on the test screen.

CTS
The Clear To Send (CTS) option allows you to define whether the CTS control lead
should be held high (on) or low (off). Selecting either on or off will override the
selection made in the HSU Card screen. The third option is normal (norm) which
means that CTS will operate in the mode selected in the HSU Card screen.

RLSD
The Receive Level Signal Detect (RLSD) option allows you to define whether the
RLSD control lead is held high (on) or low (off). The third option is normal (norm)
which means that RLSD will behave as described in Table HSU-2.

DSR
The Data Set Ready (DSR) option allows you to define whether the DSR control lead
should be held high (on) or low (off). The third option is normal (norm) which means
that DSR will behave as described in Table HSU-2.

SYNC
The Synchronization (SYNC) field tells you if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test
equipment. This is an information-only field, there are no user-selectable parameters.

BE
The Bit Error field shows the total number of bit errors logged. This is an informationonly field, there are no user-selectable parameters.

ES
The Errored Seconds field shows the total number of seconds in which any errors were
detected. This is an information-only field, there are no user-selectable parameters.

SES
The Severely Errored Seconds (SES) field shows the total number of seconds in which
the bit error rate exceeded one bit per thousand (1 x 10-3). Since this is an informationonly field, there are no user-selectable parameters.

(10-97)

Reference Guide v3.6

CSES
The Consecutive Severely Errored Seconds (CSES) field is triggered by the occurrence
of ten consecutive Severely Errored Seconds. Once triggered, the CSES field will
increment (by one) for each elapsed second until the system logs ten consecutive nonSeverely Errored Seconds. This it an information-only field there ore no user-selectable
parameters.

OSS
The Out of Synchronization Seconds field shows the number of seconds that the HSU
BERT has been out of synchronization. This is an information-only field, there are no
user-selectable parameters.

BER
The Bit Error Rate (BER) field shows the rate at which errors are being logged. The
system calculates BER by dividing the number of bit errors (BE) by the total number of
bits transmitted during the test. This is an information-only field, there are no userselectable parameters.

ELAP
The Elapsed time setting shows the running tally of the total number of seconds during
the test. This is an information-only field, there are no user-selectable parameters for
this option.

RTS
The Request To Send (RTS) field shows the current status of the RTS control lead. The
two values that can be displayed are "on" and "off." This is an information-only field,
there are no user-selectable parameters for this option.

DTR
The Data Terminal Ready (DTR) field shows the current status of the DTR control lead.
The two values that can be displayed are "on" and "off." This is an information-only
field, there are no user-selectable parameters for this option.
The DTR field will always show "on" for the 8212 HSU card (Revision A and earlier)
but it will toggle between "off" and "on" all other HSU cards.

LB ST
The Loopback State field indicates, whether there are any remotely-initiated loopbacks
currently active on the HSU port. This field will display both latching and non-latching
loopbacks that are initiated from a remote device via in band loop-up codes. In
addition to "none," the six messages that can be displayed in that field are "l-ocu," "ldsu" and "l-csu" for latching loopbacks, and "ocu," "dsu" and "csu" for non-latching
loopbacks. This is an information-only field, there are no user-selectable parameters
for this option.

Setting On-board Option Switches
Setting Switches on the 8215 HSU Card
Setting or resetting switches is necessary for conversion of the operation of all four
ports on the 8215 HSU card from RS-530 to V.35. To make this conversion, remove
the HSU card from its slot and toggle the slide switches between RS530 and V.35 as
shown in Figure HSU-11.
Ports can be set individually for either RS530 or V.35 operation features, but once set,
remain in that mode until the slide switches are reset. This information is repeated in
the Installation chapter.

Using the 1251, 1252 and 1253 Personality Modules
When using the 8202, and 8215 HSU cards, you may wish to connect the RS530 output
to V.35 (for the 8202) or RS232 equipment (for the 8202, and 8215). The 1251 (V.35),
1252 (RS232) and 1253 (RS232-E) Personality Modules were developed to assist in this
process. Shaped like a "gender changer," these modules plug into the female DB-25
port connector on the HSU card and then attach via a male cable connector to the other
equipment. For RS232 operation, the recommended length of cables should be less
than 25' and the speed no greater than 56kbps.

Introduction
8220 Sub-Rate Data Card
Each 8220 Sub-Rate Data card allows you to connect up to 10 low and medium speed
(300bps-38.4Kbps) data equipment to the system. Since an SRU port does not require a
complete 64Kbps time slot, the Sub-Rate card allows you to multiplex a number of
devices into a single, subdivided time slot on a WAN card. SRU card ports can also be
multiplexed with voice traffic on an ADPCM engine.
Each port can receive timing from either the DTE device or the system clock. If the
DTE supplies the transmit clocking, it must be synchronized with the system clocking
source.

SRU Card Settings
Figure SRU-1 shows the sub-rate data unit (SRU) screen. The ten ports correspond to
the ten RJ-48C connectors on the back of the card. Table SRU-1 lists the settings
controlled on this screen along with their possible and default values. Note: BCON
Systems will not allow same timeslot on two different WANS to reside on same SRU
Card, XCON will allow this.

NOTES
1. Time slot 16 is not available if the port is assigned to an E1 WAN link whose TS 16
is programmed for cas or ccs.
2. Speeds of .3, 1.2 and 14.4 are not supported for synchronous channels (except 14.4
sync with Frame of adpcm, hlink or nlink).
3. Communication Configuration is a three step process. This field will show n/a when
sync is chosen for the INTF option.
4. Majority Error Correction is a two step process. The user will see only choices off
and on. When on is chosen the other alternatives will appear.

STATE
The State setting determines whether the port is active or inactive. Set the State setting
to standby (stdby) for ports you are not using or have not yet configured. Set it to
active (actv) for ports that are ready for use. The control leads assume the status shown
in Table SRU-2 for the different states.

WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for
ports on the same card to be assigned to the same WAN link, or to contiguous time slots
on a WAN link.

TS
The Time Slot setting identifies the time slot on the WAN link to which this port is
connected. Values range from 01-24 for T1 links and 01-31 (excluding #16 in cas or
ccs mode) for E1 links. The Sub-Rate card can further subdivide the WAN time slot
into smaller segments for transmission of low speed data. Each WAN time slot can be
further divided into a maximum of 20 2.4Kbps time slots (see Figure SRU-2).

FRAME
The Frame setting allows you to define the sub-rate format that the port will use and to
set the usable space allotted to each WAN time slot. The choices are DSO-A (a) that
allows one sub-rate time slot, DSO-B with a limit of five sub-rate time slots (b-5),
DSO-B with a limit of ten sub-rate time slots (b-10) and DSO-B with a limit of twenty
sub-rate time slots (b-20). Figure SRU-2 shows the DS0-A and DS0-B framing sub-rate
time slot interaction. In b-20 frame, two or more SRU cards can be configured to
occupy the same WAN time slot.
Additional choices include x.50 (an ITU standard), adpcm (used to multiplex sub-rate
data on an ADPCM card) and hlink (a proprietary format used when far end of the
circuit has an ADPCM card while the near end does not). The adpcm frame uses a
24Kbps portion of the ADPCM engine. (See the ADPCM chapter for information on
using the ADPCM engines.)

RATE
The Rate setting allows you to select the rate in thousands of bits per second (kbps) for
transmission of data. The selection will change depending upon the framing mode and
interface selected.
In no case can the maximum total bandwidth of any SRU card exceed 115.2Kbps.
The maximum bandwidth of the SRU card depends upon the mode of operations for
each port. The maximum bandwidth for the sync Interface setting is 115.2Kbps and the
host will not allow more than this to be assigned.
The maximum bandwidth for async and v.14 is harder to compute because the
computation depends upon the amount of data being sent.

At a minimum, async ports have a multiplication factor of 1.2 times a sync port and
v.14 has a multiplication factor of 1.6 times that of a sync port. Using the Delay
Optimization feature will also degrade the maximum bandwidth by a factor of 1.5 times
the maximum bandwidth figure.
These computation factors suggest a maximum of 96Kbps (96Kbps x 1.2 = 115.2Kbps)
for async ports and 72Kbps (72Kbps x 1.6 = 115.2Kbps) for v.14 ports be used.
However, due to the nature of async and v.14 data transmission, we do not enforce
these limits because the user will not be transmitting data at the full rate. The Delay
Optimization feature will also degrade the maximum bandwidth by a factor of 1.5 times
the total bandwidth. BERT adds another 2x multiplication factor to the data rates
shown above.

Figure SRU-2. Time Slot Integration

SR TS
The Sub-Rate Time Slot (SR TS) indicates the sub-rate position within the DS0 time
slot that the port will occupy (see Figure SRU-2). If a framing is selected, only one
sub-rate time slot is supported and the SR TS setting will default to 1. If b-5 framing is
selected, then the sub-rate time slots available are 1-5. If b-10 framing is selected, then
the sub-rate time slots available are 1-10. If b-20 framing is selected, then the sub-rate
time slots available are 1-20. Portions of sub-rate time slots can be assigned to any
SRU port from any SRU card within the system (see Example later in this chapter). If
adpcm or hlink are chosen for the frame parameter, this field will show n/a.
In b-5 framing, if circuits with speeds greater than 9.6Kbps are assigned to the sub-rate
time slot, adjacent sub-rate time slots must be available to accommodate their size. A
19.2Kbps circuit would occupy two contiguous sub-rate time slots (leaving space for up
to three 9.6Kbps circuits) and a 38.4Kbps circuit would occupy four contiguous sub-rate
time slots (leaving space for one 9.6Kbps circuit).
The SR TS number selected will be the first segment occupied by this circuit. If a
28.8Kbps circuit occupies three segments of the b-5 frame, selecting SR TS #1 will
assign it to segments 1, 2 and 3. Segments 4 and 5 may be assigned either
independently to 9.6 (or less)Kbps circuits in SR TS #4 and #5 or combined for a
19.2Kbps circuit assigned to SR TS #4.

SRU Card

If a circuit exceeds the slots necessary to accommodate it, such as a 38.4Kbps circuit to
SR TS #3 in b-5 framing, the message, "Invalid SR TS," will be displayed. If a circuit
requires more space than the SR TS has available, such as having a 38.4Kbps circuit in
SR TS #1 and then attempting to assign a 19.2Kbps circuit to SR TS #4, the message
"SR TS overlapping," will be displayed.
The number of sub-rate timeslots available for x.50 will depend upon the Rate selected.
If the 2.4 Rate is selected, the number available will be 20. If the 4.8 Rate is selected,
the number available will be 10. If the 9.6 Rate is selected, the number available will
be 5. When multiplexing different rate circuits on the same timeslot, the following
formula is necessary to compute the position in the sub-rate timeslot: a 9.6 circuit will
occupy slots n, n+5, n+10 and n+15; a 4.8 circuit will occupy slots n and n+10; a 2.4
circuit will occupy slots n (where n = the timeslot selected).

INTF
The Interface setting allows you to choose the protocol necessary for the terminal
associated with this port. The choices are Asynchronous (asyn), Synchronous (sync)
and v.14 (v.14). If Synchronous transmission is selected, the choices for STOP, DATA
and PAR will show as not applicable (n/a).
Both asyn and v.14 options provide asynchronous to synchronous conversion. The v.14
option is an industry standard which will allow the SRU card to interoperate with many
DSUs. The asyn option is a streamlined proprietary algorithm which will increase the
performance of the SRU card.

COM CF
The Communication Configuration setting is a three step process that allows the user to
choose the Data bits, Stop bits and Parity settings. The Data setting allows you to
change the bits-per-byte number depending upon the type of terminal associated with
this particular port. The options are 8, 7, 6, 5.
The second option allows you to select the number of Stop bits that check data
sampling for the terminal associated with this port. The choices are 1 and 2.
The third choice is the Parity setting that changes the data parity for the terminal
associated with this particular port. The options are none, odd, even, space and mark.

CTS
The Clear To Send setting allows you to define how the port should respond to receipt
of Request to Send (RTS) from the attached equipment. This setting also allows you to
change the delay time (in milliseconds) from when the SRU receives the RTS until it
issues the CTS. The local option allows RTS to control CTS. The remote-local options
allows RTS to control both the CTS of the local equipment and RLSD of the remote
equipment. The options are permanent (perm), local - immediate (l0), local -30 mS
(l30), local -60 mS (l60), local -100 mS (l100), remote/local - immediate (rl0),
remote/local - 30 mS (rl3), remote/local - 60 mS (rl6), remote/local - 100 mS (rl10)
and off.

TX CLK
The Transmit Clock setting allows the user to select the clocking source for this port.
The options are n/a, if async INTF is chosen and internal (int), if sync INTF is chosen.
The int setting uses the system for the clock source and the ext setting allows the DTE
to generate the transmit clocking information.

LB
The Loopback setting allows you to activate local loopbacks on the SRU. The settings
are off, toward the DTE (dte) and toward the network (net). Figure SRU-3 shows a
diagram of the two loopback conditions.

LB GEN
The Loopback Generate setting generates in-band diagnostic codes that are sent to the
remote equipment These codes are compatible with DDS networks and allow you to
command a latching loopback at remote DDS equipment. You can start loopbacks at
the remote ocu (Office Channel Unit), the dsu (Data Service Unit) or the csu (Channel
Service Unit). Figures 8B-4, 8B-5 and 8B-6 show the loopback locations. You can
also turn all of the loopbacks off. This field will show n/a if adpcm or hlink are
chosen for the FRAME parameter.
Loop-up or loop-down commands cannot be implemented for two ports on the same
card simultaneously. The user must finish all loopback operations on one port before
attempting to perform any loopback operations on another port.

LB DET
The Loopback Detection setting determines how the SRU Card will respond to latching
and non-latching loopback commands from remote equipment. The SRU reacts only to
the in-band DDS format loopback commands for OCU Loop, CSU Loop, and DSU
Loop. The Loopback Detection setting does not affect local loopback commands from
the local control terminal.
The (on) option causes the SRU Card to monitor ports for DDS format loopback
commands from the remote equipment. If the SRU Card detects a loopback command,
it loops the data back until the remote equipment sends a stop loopback command. The
with time-out (w/to) option is the same as the on option, except that after ten minutes
the SRU Card automatically releases loopbacks commanded by the remote equipment.
The off option causes the SRU Card to ignore all remote loopback commands. This
field will show n/a if adpcm or hlink are chosen for the FRAME parameter.

Reference Guide v3.6

DL OPT
Delay Optimization decreases the end-to-end delay time for applications that require
lower delay time. The options are off and on.
The cost for using Delay Optimization is a decrease in total bandwidth for the card by a
factor of 1.5. For example, a user that has 10 ports using the sync Interface will have
115.2Kbps maximum bandwidth available. If delay optimization is used on all 10
ports, the maximum bandwidth available will be 76.8Kbps.

ADPCM
If adpcm is chosen for the FRAME parameter, this field will allow the user to select the
ADPCM card to direct this traffic. The options are P1, P2 or P3. These are the
communications server card slot designations that are stamped on the chassis. If any
other option is selected this field will show n/a.

MAJ EC
The Majority Vote Error Correction parameter is available for ports using DSOA
framing and having speeds of 9.6Kbps and lower. Option selection is done in a two
step operation. The initial options are off and on. If the on option is chosen, a new set
of options will appear at the bottom of the screen.
The new options are used to select the error threshold, above which the card will
generate an alarm. The choices are none, 10e-3, 10e-4, 10e-5, 10e-6 and 10e-7. While
the majority vote algorithm is capable of correcting error rates in excess of 10e-3, the
Excessive Error Rate alarm is designed to give system administrators advanced notice
of problems before users detect them. Table SRU-3 shows the bit error rates for
Majority Vote error correction.

Examples
Figure SRU-7 shows some of the ways SRU cards can be used to network low-speed
data using the DS0-A and DS0-B framing. In this diagram, five SRU Cards are
connected to eight WAN time slots, on one WAN port, on one WAN card (many
combinations of cards/ports/time slots are possible). Each SRU card is separated to
show the ten ports on each card. Each port is assigned to a low-speed data device and
the transmission speed of that device is shown in the center of the SRU port. The
diagram sometimes shows only one connection to eliminate unnecessary lines in the
diagram. Each port is a direct connection and will not support interchange of data
transmission between ports.
The first time a WAN card/port/time slot is used, the framing selected on the SRU port
will segregate that WAN time slot into SRU time slots. Once selected, those SRU TSs
will apply to all ports assigned to that WAN time slot.
Once the framing is selected for the WAN card/port/time slot, low-speed data devices
can be arranged and selected on the SRU card settings to maximize the system
capabilities.
In this example, the first port on SRU #1 assigned a framing to WAN 1-1, TS 1, and
selected a 38.4Kbps device for its use. The second port has b-5 framing to WAN 1-1,
TS 2. Of the five SRU time slots on that WAN time slot, the first three are used to
support a 28.8Kbps device (three 9.6Kbps contiguous SRU time slots). The 9.6Kbps
device on SRU #1 port #3 occupies the fourth SRU time slot and another 9.6Kbps from
SRU #3, port #10, is placed in the fifth slot.
WAN 1-1, TS 3 was segregated into ten SRU time slots by the selection of b-10
framing that supports either .3, 1.2, 2.4 or 4.8Kbps transmission. Six 4.8Kbps ports are
assigned to the first six SRU time slots. The diagram shows only one connection to
eliminate unnecessary lines in the diagram. The six ports are six direct connections
and will not support interchange of data transmission. The other four SRU time slots
are used by ports 1-4 on SRU #4. Again, the single line does not imply interexchange.

(10-97)

Page 8-B-9

SRU Card

Reference Guide v3.6

WAN 1-1, TS 4 has b-20 framing and will support up to twenty .3, 1.2 or 2.4Kbps
circuits from two (or more) SRU cards. In this example, SRU #1, port #10 is assigned
to SRU TS #1, SRU #2, ports 1-10 are assigned to SRU TS 2-11. The nine SRU time
slots left are used by SRU #3, ports 1-9. As mentioned earlier, SRU #3, port #10 is a
9.6Kbps circuit assigned to WAN 1-1, TS 2, SRU time slot #5. WAN 1-1, TS 5, has a
framing. Only one device can transmit data in this SRU time slot. In this example, a
2.4Kbps circuit was assigned to SRU #4, port #5.
WAN 1-1, TS 6 has b-5 framing, so five SRU time slots are available. The first two
9.6Kbps slots are used by a 19.2Kbps circuit on SRU #4, port #6, while the other three
are used by 9.6Kbps circuits on SRU #4, ports 7-9.
WAN 1-1, TS 7 has the same characteristics as TS 6, except that the first SRU time slot
is used by a 9.6Kbps circuit on SRU #4, port #10, SRU time slots 2-4 are assigned to
the single 28.8 port on SRU #5. WAN 1-1, TS 8 was designated as b-10 framing and
the first eight SRU time slots are associated with the 2.4 and 4.8Kbps circuits on SRU
#5, ports 3-10.

BERT
Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected SRU port. The patterns that can be selected are off, mark (all ones),
space (all zeros), 1:1 (one-zero-one-zero), 1:7 (one-7 zeros-one-7 zeros), 511 (511 test
pattern) and 2047 (2047 test pattern).

DIR
The Direction (DIR) setting allows you to specify where the BERT test signal should be
directed. The first option is net (network) which means that the test signal will be
transmitted through the system toward the Wide Area Network (WAN). The user
option means that the signal will be directed toward the attached DTE device over the
RS232 interface.

CTS
The Clear To Send (CTS) option allows you to define whether the CTS control lead
should be held high (on) or low (off). Selecting either on or off will override the
selection made in the SRU Card screen. The third option is normal (norm) which
means that CTS will behave as described in Table SRU-2.

RLSD
The Receive Level Signal Detect (RLSD) option allows you to define whether the
RLSD control lead should be held high (on) or low (off). The third option is normal
(norm) which means that RLSD will behave as described in Table SRU-2.

SYNC
The Synchronization (SYNC) field tells you if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test
equipment. Since this is an information-only field, there are no user-selectable
parameters.

BE
The Bit Error field shows the total number of bit errors logged. Since this is an
information-only field, there are no user-selectable parameters.

ES
The Errored Seconds field shows the total number of seconds in which any errors were
detected. Since this is an information-only field, there are no user-selectable
parameters.

Page 8-B-13

SRU Card

Reference Guide v3.6

SES
The Severely Errored Seconds (SES) field shows the total number of seconds in which
the bit error rate exceeded one bit per thousand (1 x 10-3). Since this is an informationonly field, there are no user-selectable parameters.

CSES
The Consecutive Severely Errored Seconds (CSES) field is triggered by the occurrence
of ten consecutive Severely Errored Seconds. Once triggered, the CSES field will
increment (by one) for each elapsed second until the system logs ten consecutive nonSeverely Errored Seconds. Since this it an information-only field there are no userselectable parameters.

OSS
The Out of Synchronization Seconds field shows the number of seconds that the SRU
BERT has been out of synchronization. Since this is an information-only field, there
are no user-selectable parameters.

BER
The Bit Error Rate (BER) field shows the rate at which errors are being logged. The
system calculates BER by dividing the number of bit errors (BE) by the total number of
bits transmitted during the test. Since this is an information-only field, there are no
user-selectable parameters.

ELAP
The Elapsed time setting shows the running tally of the total number of seconds during
the test. Since this is an information-only field, there are no user-selectable parameters
for this option.

RTS
The Request To Send (RTS) field shows the current status of the RTS control lead. The
two values that can be displayed are "on" and "off." Since this is an information-only
field, there are no user-selectable parameters for this option.

SR OSS
The Subrate Out of Synchronization Seconds (SR OSS) field shows how many seconds
in which there was a Subrate framing loss. Since this is an information-only field, there
are no user-selectable parameters for this option.

SRU Card

LB ST
The Loopback State (LB ST) field indicates whether there are any remotely-initiated
loopbacks currently active on the SRU port. This field will display both latching and
non-latching loopbacks that are initiated from a remote device via in-band loop-up
codes. In addition to "none," the six possible messages that can be displayed in that
field are "l-ocu," "l-dsu" and "l-csu" for latching loopbacks, and "ocu," "dsu" and "csu"
for non-latching loopbacks. Since this is an information-only field, there are no userselectable parameters for this option.

EER
The Excessive Error field will display the computed the DS0 error rate for each port
where that option was selected. The Majority Error Rate will be computed based on the
integration period for the selected threshold. For example, if the 10e-4 threshold was
selected, the integration would be ten seconds.

OCU-DP Cards

Introduction
The OCU-DP (Office Channel Unit–Data Port) is used to interface directly to Data
Service Units (DSUs)/Channel Service Units (CSUs) supporting data traffic up to and
including 64kbps. A four-wire circuit can connect the OCU-DP card to a DSU/CSU
that can be located up to four miles away. In Switched 56kbps mode, users access the
network on an as-needed basis by dial-up commands. The system must be equipped to
provide -48VDC power to fully support the functionality of the OCU-DP card.

8249 OCU-DP Card
The 8249 OCU-DP card supports two ports, each of which may be connected to a
DSU/CSU operating at 64kbps, 56kbps, Switched 56kbps, 19.2kbps, 9.6kbps, 4.8kbps
or 2.4kbps. Secondary channel operation is supported from 2.4 to 56kbps.

8247 OCU-DP Card
The 8247 OCU-DP card supports ten ports, five of which require installation of the 845
child card to become operational. The 8247 supports all the features and functions of
the 8249 two-port OCU-DP card with the following exceptions:
•

BCH Error correction is not supported

•

Performance monitoring is not supported

•

Operation in CSU mode is not supported

845 OCU-DP Child Card
The 845 OCU-DP Child Card is a piggy-back addition to the 8247 OCU-DP card that
activates the additional five data ports on the 8247.

8248 OCU-DP Card
The 8248 OCU-DP card is an older version of the 8247 OCU-DP that supports five
ports with the installation of the 845 child card.

OCU-DP Card

NOTES
1. The maj-v option is supported on all cards if the Rate is 2.4, 4.8 or 9.6. The bch
option is supported only if the Rate is 19.2 , 56k or 64k in systems using the 8800
and 8804 CPU Cards or the Rate is 19.2 with systems using the 8801 CPU Card.
Error Correction is not supported if the Rate is sw56k. BCH Error Correction is not
supported on the 5-port and 10-port OCU-DP card.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the state setting to standby (stdby) for
ports you are not using or have not yet configured. Set it to active (actv) for ports that
are ready for use.

WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for
all ports on the same card to be assigned to the same WAN link, or to be assigned to
contiguous time slots on a WAN link.

TS
The TS setting identifies the time slot on the WAN link to which this port is connected.
Values range from 01 to 24 for T1 links and 01 to 31 (excluding TS 16 in cas or ccs
mode) for E1 links. For a display of the available time slots, refer to your cross-connect
map for the WAN link; see the Operations chapter for information about viewing crossconnect maps.

FRAME
The Frame setting allows you to set up the framing of the DS0 to which the OCU-DP
port is connected. The choices, as diagrammed in Figure OCU-2, are DSO-A (a), DSOB with a limit of five ports (b-5), DSO-B with a limit of ten ports (b-10), DSO-B with a
limit of twenty ports (b-20).

RATE
The Rate setting identifies the highest data transmission rate for the OCU-DP port.
Values are 2.4, 4.8, 9.6, 19.2, 56k, 64k and sw56k (switched 56kbps). See Figure
OCU-2.

(10-97)

Page 8-C-3

OCU-DP Card

Reference Guide v3.6

SR TS
The Sub-Rate Time Slot (SR TS) indicates the sub-rate position within the DS0 time
slot that the port will occupy (see Figure OCU-2). If a framing is selected, only one
sub-rate time slot is supported and the SR TS setting will default to 1. If b-5 framing is
selected, then the sub-rate time slots available are 1-5. If b-10 framing is selected, then
the sub-rate time slots available are 1-10. If b-20 framing is selected, then the sub-rate
time slots available are 1-20.
In b-5 framing, if circuits with speeds greater than 9.6kbps are assigned to the sub-rate
time slot, adjacent sub-rate time slots must be available to accommodate their size. A
19.2kbps circuit would occupy two contiguous sub-rate time slots (leaving space for up
to three 9.6kbps circuits from other OCU-DP cards and ports).
The SR TS number selected will be the first segment occupied by this circuit. If a
19.2kbps circuit occupies two segments of the b-5 frame, selecting SR TS #1 will
assign it to segments 1 and 2. Segments 3, 4 and 5 may be assigned either
independently to 9.6kbps (or less) circuits from other OCU-DP cards.
If a circuit is assigned that exceeds the slots necessary to accommodate it, such as a
19.2kbps circuit to SR TS #5 in b-5 framing, the message, "Invalid SR TS," will be
displayed. If a circuit requires more space than the SR TS has available, such as a
having a 19.2kbps circuit assigned to SR TS #1, a 19.2kbps circuit assigned to SR TS
#3 and then attempting to assign a 19.2kbps circuit to SR TS #4, the message "SR TS
overlapping," will be displayed.

MODE
The Mode setting options are ocu and csu. You should select ocu (which is by far the
more common) whenever the OCU-DP port is attached to a CSU/DSU over a 4-wire
circuit. In that mode, the OCU-DP port will generate the necessary sealing current and
the CSU/DSU will terminate it. The csu mode should not be used unless you have two
back-to-back OCU-DP ports. In that case, to achieve proper orientation and sealing
current, one of two OCU-DP ports should be configured for ocu mode and the other for
csu mode. The csu mode is not supported on the 5-port and 10-port OCU-DP card.

(10-97)

Reference Guide v3.6

OCU-DP Card

ERR COR
The Error Correction setting provides for different methods of error correction
depending upon the Rate selected. The default ERR COR setting is off. When sub-rate
speeds of 9.6k or less are chosen in the Rate setting, the Error Correction setting of
maj-v (majority vote) is available. Using the majority vote option allows the system to
do error-polling and decision-making based upon the repeated bit pattern.
The bch error correction is available for rates of 19.2, 56k and 64k on the 8800 and
8804 CPU Cards or a 19.2 rate on the 8801 CPU Card. Using bch with either 56k or
64k requires an additional WAN timeslot to carry the error correction information. The
WAN timeslot selected must be larger than the one chosen in the TS option (e.g., if
timeslot #17 is chosen for TS, the timeslot used for error correction must be #18-24 for
T1 systems and #18-31 for E1 systems).
Error Correction is not supported on the 5-port and 10-port OCU-DP card.

SECOND
Secondary channel allows the CSU/DSU to establish a separate lower speed data circuit
with the OCU-DP port. When synchronized, this special circuit can be used for testing
and maintenance of the main circuit or for the transmission of other low-speed data.
The settings are on and off.
The secondary channel is transported in the 8th bit position of the DS0 to which the
OCU-DP is assigned. The following chart shows the secondary channel rate associated
with the various primary port rates supported on the OCU-DP card. For a further
description of the secondary channel function refer to Pub 62310 and TA TSY 000077
and TA TSY 000083.

USER LB
The User Loopback (USER LB) is a specialized code conversion function that is only
relevant in Taiwan and some other countries in the Far East. The two options are d and
o, neither of which has any effect in North America.

LB
The OCU-DP card supports three Loopback options that act on the card itself. The dte
option loops the 4-wire analog interface of the OCU-DP port towards the attached
CSU/DSU. It is used to test the local cabling and the analog drivers in the OCU-DP
card (see Figure OCU-3).

(10-97)

The network A (net-a) option loops the 4-wire OCU-DP interface towards the network.
It is used to test all of the OCU-DP card circuitry, the system common equipment, the
WAN link card, the remote equipment, and the WAN line between the two sites (see
Figure OCU-4).
The network D (net-d) option puts a loopback towards the network at the point where
the OCU-DP card interfaces with the system bus. It serves to separate the OCU-DP
card circuitry from the system common equipment, the WAN link card, the remote
equipment, and the WAN line between the two sites (see Figure OCU-5).

The Loopback Generate settings initiate various in-band diagnostic codes sent to the
remote equipment. These codes are compatible with DDS networks and allow you to
command a latching loopback at remote DDS equipment. The ds0-n loopback loops
the analog interface of the remote OCU-DP device back towards the network for
circuits using the 64k Rate. The ocu-n loopback loops the analog interface of the
remote OCU-DP device back towards the network for circuits using the 56k or less
Rates. The csu-n loopback loops the 4-wire interface of the remote CSU/DSU device
back towards the network. A 48V converter is required for this loopback.

The csu-u loopback loops the 4-wire interface of the local CSU/DSU device towards
the network. Figures OCU-6, -7, and -8 show the loopback locations. You can also
turn all remote loopbacks off.
Loop-up or loop-down commands cannot be implemented for two ports on the same
card simultaneously. The user must finish all loopback operations on one port before
attempting to perform any loopback operations on another port.

Figure OCU-8. OCU Remote Loopback (csu-u option)

LB DET
The Loopback Detection setting determines how the system responds to latching and
non-latching loopback commands from remote equipment. The OCU-DP reacts only to
the in-band DDS format loopback commands for Channel Loop, OCU Loop, and DSU
Loop. The Loopback Detection setting does not affect local loopback commands from
the local control terminal. The settings are off, on and w/to (on with time out).
The off option causes the system to ignore all remote loopback commands. The on
option causes the system to monitor for DDS format loopback commands from the
remote equipment. If the system detects a loopback command, it loops the data back
until the remote equipment sends a stop loopback command. The with time-out (w/to)
option is the same as the on option, except that after ten minutes the system
automatically releases loopbacks commanded by the remote equipment.
When using the OCU-DP port for a clear-channel, 64kbps circuit in DS0A mode, you
should set the loopback detection to off to prevent unintentional loopback activation.

BERT
Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected OCU-DP port. The patterns that can be selected are off, mark (all
ones), space (all zeros), 1:1 (1010), 1:7 (0100-0000), 511 (511 test pattern), 2047 (2047
test pattern) and qrss (quasi-random pseudo signal).

DIR
The Direction (DIR) setting allows you to specify where the BERT test signal should be
directed. The first option is net (network) which means that the test signal will be
transmitted through the system toward the Wide Area Network (WAN). The user
option means that the signal will be directed toward the attached CSU/DSU device over
the 4-wire interface.

DATA
The DATA setting specifies whether the BERT test signal should be connected to the
Primary (pri) or the Secondary (sec) channel of the OCU-DP port. If there is no
Secondary channel associated with the OCU-DP port, then the only option available is
pri.

SYNC
The Synchronization (SYNC) field tells you if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test
equipment. Since this is an information-only field, there are no user-selectable
parameters.

BE
The Bit Error field shows the total number of bit errors logged. Since this is an
information-only field, there are no user-selectable parameters.

ES
The Errored Seconds field shows the total number of seconds in which any errors were
detected. Since this is an information-only field, there are no user-selectable
parameters.

SES
The Severely Errored Seconds (SES) field shows the total number of seconds in which
the bit error rate exceeded one bit per thousand (1 x 10-3). Since this is an informationonly field, there are no user-selectable parameters.

CSES
The Consecutive Severely Errored Seconds (CSES) field is triggered by the occurrence
of ten consecutive Severely Errored Seconds. Once triggered, the CSES field will
increment (by one) for each elapsed second until the system logs ten consecutive nonSeverely Errored Seconds. Since this it an information-only field there ore no userselectable parameters.

OSS
The Out of Synchronization Seconds field shows the number of seconds that the OCUDP BERT has been out of synchronization. Since this is an information-only field,
there are no user-selectable parameters.

BER
The Bit Error Rate (BER) field shows the rate at which errors are being logged. The
system calculates BER by dividing the number of bit errors (BE) by the total number of
bits transmitted during the test. Since this is an information-only field, there are no
user-selectable parameters.

ELAP
The Elapsed time setting shows the running tally of the total number of seconds during
the test. Since this is an information-only field, there are no user-selectable parameters
for this option.

4W DDS
The 4-wire DDS setting shows if the 4-wire interface is both present and operational.
The field will show norm if the interface is connected or nos for No Signal.

OCU-DP Error Correction and Performance Monitoring
If "majority vote" or "BCH" error correction is enabled on the two-port OCU-DP card,
then the system will support performance monitoring of the data traffic. The
performance monitoring screen is accessed by selecting one of the two ports from the
OCU-DP card main screen and typing "p." Error correction and performance
monitoring are not supported on the 5-port and 10-port OCU-DP card.
If the BCH method of error correction is selected, then the OCU-DP card will monitor
the data traffic coming in from the T1 network and use the BCH polynomial values that
accompany the data to log the number of errors and to attempt to correct such errors.
Any data errors that are observed are considered "input" data errors and contribute to
the input error statistics such as Input Errored Seconds (IES), Input Severely Errored
Seconds (ISES) and Input Consecutive Severely Errored Seconds (ICSES). Depending
upon the severity of the input errors, the BCH algorithm may be able to correct the data
prior to transmitting it over the four-wire DDS circuit. If an error is so severe that it
cannot be corrected, then it will also be logged as an "output" data error and will
increment the Output Errored Seconds (OES), Output Severely Errored Seconds (OSES)
and Output Consecutive Severely Errored Seconds (OCSES) counters.
If the majority vote method of error correction is selected, then the OCU-DP card will
monitor the data traffic coming in from the T1 network and use the majority vote
algorithm to determine if any data errors have occurred. Any data errors that are
observed are considered "input" data errors and contribute to the input error statistics
such as Input Errored Seconds (IES), Input Severely Errored Seconds (ISES) and Input
Consecutive Severely Errored Seconds (ICSES). Since the majority vote algorithm
assumes that it can correct any data input errors, the "output" data error category has no
meaning in this context. Consequently, the Output Errored Seconds (OES), Output
Severely Errored Seconds (OSES) and Output Consecutive Severely Errored Seconds
(OCSES) fields do not apply to the majority vote mode.
Figure OCU-10 shows the OCU-DP performance monitoring screen. Performance
statistics covering the previous twenty-four hours are available and are totaled-up at the
bottom of the screen.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy time slots on a WAN link. Set the State setting to standby (stdby ) for a
port you are not using or have not yet configured. Set it to active (actv ) for a port that
is ready for use.

PRT TYPE
The Port Type identifies the type of interface expected for this port. The selections are
frad and conc. If frad is selected, the rs232 or serv is the usual input source. If conc is
selected then wan is the usual input source.

SRC
The Source parameter allows the user to select the type and source of data input to that
port. The options are wan, serv and rs232 . If rs232 is selected, the card will expect
direct transmission of data through the corresponding RS232 input port (i.e. the eight
numbers at the top of the screen are also associated with the eight user ports on the back
of the card).
The User card is set up as four groups of two ports each (1-2, 3-4, 5-6, 7-8 and 9-10).
These ports are considered pairs so that if rs232 is selected for port #1, port #2 will also
require RS232 input.

FRAD Card

TS
The Timeslot (TS) setting identifies the time slot on the WAN link to which the Frame
Relay port is connected. Highlight the table option and press the "Enter" key. At the
bottom of the screen, the system will display the time slots that can be assigned to the
WAN link selected in the previous selection (i.e. if w1-1 is chosen and the SRC option
is either CSU or DSX, 24 timeslots will show available for assignment, if w1-1 is
CEPT, 30 timeslots will show available for assignment). Only one timeslot can be
selected for each Frame Relay port.

RATE
The Rate parameter is user selectable depending upon the SRC and the Format settings.
If frad and rs232 is selected, the options (in Kbps) are 2.4 to 38.4. Since these ports are
considered pairs, if rs232 is selected above for port #3, port #4 will also have choices
for 2.4 to 38.4Kbps rates.
If conc is selected the rate parameter selection options will be 56k and 64k

DLCI
The Data Link Connection Identifier (DLCI) identifies the frame's logical connection
within the Frame Relay port. This number is assigned by the carrier. The options are 16
through 991.

vendor, is necessary to enable the external clock.)

LB
The Loopback (LB) setting allows you to activate a number of different loopback
options for RS232 (Figure FRAD-2). The off option is the default setting. The dte
(DTE) loops data from the local DTE back to itself through the local FRAD card. The

DS0-DP Card

Introduction
The 8254 DS0 Data Port/G.703 Contradirectional/Codirectional Data Unit (DS0DP/G.703) is a plug-in user card for the system. The DS0-DP/G.703 provides a 64kbps
interface to a DS0 of a T1/E1 network. Since the byte alignment of the 64kbps data
stream to the DS0 is essential, the interface provides a 64kbps bit clock and a 8KHz
byte clock in the DS0-DP mode, and a composite clock/data signal in the G.703 mode.

DS0-DP Card Settings
Figure DS0-1 shows the DS0-DP screen. Table DS0-1 lists the settings controlled on

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the state setting to standby (stdby) for
ports you are not using or have not yet configured. Set it to active (actv) for ports that
are ready for use.

WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for
all ports on the same card to be assigned to the same WAN link, or to contiguous time
slots on a WAN link.

TS
The TS setting identifies the time slot on the WAN link to which this port is assigned.
Values range from 1-24 for T1 links and 1-31 (excluding time slot 16 in cas or ccs
mode) for E1 links. For a display of the available time slots, refer to your cross-connect
map for the WAN link; see the Operations chapter for information about viewing crossconnect maps.

MODE
This option displays the selection of modes. In ds0dp mode, the port will provide a
common bit and byte clock to be used by the attached DTE device for both receive and
transmit. When one port is set to ds0dp all other ports will default to the DS0-DP mode
as well. Similarly, when one port is changed to one of the G.703 modes (Codirectional
or Contradirectional), any port set for the DS0-DP mode will default to the
Contradirectional mode. The contr selection configures the port for the
Contradirectional mode. In this mode, the card supplies both the transmit and receive
clocks to the DTE. The codir selection configures the port for the Codirectional mode.
In this mode, the clocks and data make up a composite signal. The clocks must be
derived from the data.

Page 8-E-2

(10-97)

Reference Guide v3.6

DS0-DP Card

CLK
This option allows the selection of the desired clocking mode when in the DS0-DP
mode. When set to int, the card generates the bit and byte clocks to the DTE. When set
to ext, the card receives the bit and byte clocks from the attached device. All ports must
have the same clock setting, therefore, when one port is changed, all ports are changed.
When a G.703 mode is selected, this option defaults to n/a.

LB
This option allows the user to set local loopbacks. The off option is for no loopbacks.
The dte selection loops data towards the DTE. The net option loops data towards the
network.

LB GEN
This option allows the user to set local loopbacks. The off option is for no loopbacks.
The other options (ocu, dsu, csu, ds0) force the card to send the appropriate DDS
latching loopback code towards the remote end. This option will only function in the
DS0-DP mode.

LB DET
This option allows the card to detect DDS latching loopbacks. When set to off, no
loopbacks can be detected. When set to enab, loopbacks will be detected. When a
loopback is detected, it will be maintained until a loop down is detected. w/to is the
same as enab except that if no loop down is detected after 10 minutes, the loopback
will self-terminate. This option only functions in the DS0-DP mode.

B7R Card

Introduction
The B7R Data card enables the system to accept network management information
from each of eight separate DS0s and multiplex them into a single 38.4kbps
asynchronous bitstream running the Serial Line Interface Protocol (SLIP). (See the
Network Management section of the CPU card chapter.)

8228 Bit-7-Redundant (B7R) Card
The 8228 B7R Card will multiplex up to eight B7R formatted data channels from eight
different DS0s. This card has a separate maintenance and testing channel (port #9) and
a single aggregate channel (port #10) to redirect information from the DS0s to the
single RS232 connector on the back of the card.
Figure B7R-1 shows the part the B7R card plays in the Network Management System.
SNMP alarm traps and TELNET configuration run over this path. Both formats can use
the 4kbps FDL (Facility Data Link) on a T1 link using ESF format, a full DS0 on a T1
link or the computer port of the Interface card using SLIP protocol.
If the FDL is used to transmit and receive information, a DACSII (6.1 or higher) must
be used to convert the FDL/IP information to a full DS0. (On point-to-point circuits, a
DACSII is not needed.) A B7R card is used at the NMS site to multiplex the contents
of eight DS0 circuits into a single 38.4kbps asynchronous circuit using SLIP protocol
for use by a communication server or terminal server for routing to a Local Area
Network.

Reference Guide v3.6

B7R Card

3. The IP address of ports #1-8 must match the IP address assigned to the remote
system on that DS0. Port #9 does not require an IP address because it is a debug
port.
4. Ports #1-8 share the same subnetwork mask, and the subnet address for ports #1-8
must be different from the one used for port #10.

STATE
The State setting determines whether the port is active or inactive. Set the State setting
to standby (stdby) for ports you are not using or have not yet configured. Set it to
active (actv) for ports that are ready for use. Port #9 is used for debug purposes and is
normally in the stdby position.

WAN
The WAN setting identifies the WAN link that carries the data for this B7R port (either
from the DACS or directly from the WAN link). The choices for this setting are w1-1
through w4-2. Ports #9 and #10 do not require input from WAN links, therefore this
field shows n/a for these ports.

TS
The TS (timeslot) setting identifies the timeslot on the WAN link carrying data for the
B7R port (either from the DACS or directly from the WAN link). Acceptable values
for this field are 01-24 for a T1 link or 01-15 and 17-31 for an E1 link.
Generally, timeslots are assigned sequentially. For example, card #1 would be assigned
to ports 1-8, card #2 to ports 9-16 and card #3 would be assigned to ports 17-24, but
this is not required.

RATE
The Rate setting allows you to select the rate in thousands of bits per second (kbps) for
transmission of data. The rate of ports #1-8 are preset to 4kbps. The rate of port #9 is
preset to 9.6kbps. The options for port #10 are 9.6, 19.2, 28.8 and 38.4. Since the
combined output of ports #1-8 are 32kbps, port #10 should be set to 38.4 to
accommodate a full system.

COM CF
The Communication Configuration setting is not applicable for ports #1-8 and the n/a
value cannot be changed. Ports #9-10 can be changed in a three step procedure that
selects the data bits, parity and stop bits. The default values are 8, N, 1.

Page 8-F-3

B7R Card

Reference Guide v3.6

CTS
The Clear To Send setting selects an option that will allow hardware handshaking with
the terminal server and the B7R card when enabled for port #10. Since it is not
applicable for ports #1-8, the n/a value cannot be changed. Ports #9-10 can be
changed. The values for this setting are off and on.
All cabling must be terminated before activating the CTS feature.

ADDR
The Address setting defines the IP address for each Integrated Access Controller
associated with the first eight ports and port #10. Port #9 does not require an IP address
and cannot be changed from the n/a setting. This address must be the same as the
address used in the PORT IP ADDR field on the Interface card of the system with
which it is associated for ports #1-8. The IP address for port #10 is a unique address for
each B7R card and must be on a different network than ports #1-8. This allows the user
to "ping" each B7R card itself for system diagnostics.

NETMSK
The Network Mask setting defines the single subnet mask address for each system
associated with the first eight ports and a different subnet mask for port #10. A change
of subnet mask for any of the first eight ports will change all of the ports. Port #9 does
not require a subnet mask and cannot be changed from the n/a setting. This address
must be the same as the address used in the NETMASK field on the Interface card of
the system with which it is associated for ports #1-8.

The Basic Rate Interface (BRI) user card offers non-switched connectivity to sites
located up to 18,000 feet from the system location. Factors such as wire gauge, bridge
tap and loading patterns are described in ANSI T1.601-1992 specifications. The 8260
and 8261 BRI cards are equipped with eight (8) “U” interfaces, each of which can carry
one BRI, 2B+D channel, providing either two 64Kbps or one 128Kbps bearer channels
per interface.
The 8262 four-wire BRI card supports the “S” and “T” interfaces. The connection
distances for this card are largely dependent on the number of devices connected to the
card.

8260 BRI Card
The 8260 BRI Card has software selectable mode operations of LT and NT. The 8260
supports up to eight leased or BRI terminal extension (brite) applications. The 8260
does not support sealing current and does not provide any DC termination.

8261 BRI Card
The 8261 BRI Card has all of the functionality of the 8260. Switching between the LT
and NT modes requires both making a menu selection and changing jumper connections
on the card (see Figure BRI-14). The 8261 supports sealing current of 7.5mA or
15.0mA for a number of different times and duration.
To activate sealing current, set the jumpers on the card to the desired position (see
Figure BRI-15 for jumper locations) also set SEAL CURR to on (see Figure BRI-2).
The Sealing Current screen (see Figure BRI-3) provides for setting the start time,
duration, and repeat interval.
This card is shipped with jumpers attached that make the automatic default for the card
LT and 15mA sealing current. (Sealing current is not applicable in NT mode.)
The 8260 and 8261 are very similar in operation and will be discussed together at the
start of the chapter. The 8262 BRI Card is sufficiently different that its screen and
operation information is included separately.

8262 BRI Card
The 8262 BRI Card is designed to support “S/T” 4-wire interface applications. It also
supports both internal and external phantom power arrangements. Jumpers are
available to select termination’s on the receive and transmit sides individually.

BRI Circuit Applications
Figure BRI-1 shows the difference between the two circuit types, Leased line (lease)
and BRI Terminal Extension (brite). The leased circuit can be any standard 2B1Q (U
interface) NTU device that supports "nailed-up" (1 or 2 B channels) connections with
no D channel signaling. The brite mode supports switched connectivity to ISDN
capable switches and D channel signaling on either a full DS0 or multiplexed 4:1 on a
single DS0.
For both examples, B channels carrying voice traffic on the BRI card can be
compressed through the ADPCM card to extend the user's resources (see Conversion
section). The only limitation on BRI traffic is that NTUs or NT1s must be located less
than 18,000 feet from the system unit.

SRV functions will be activated in a future release.

STATE
The State setting determines whether the port is active or inactive. An inactive port
does not occupy a time slot on a WAN link. Set the State option to standby (stdby) for
ports you are not using or have not yet configured. Set it to active (actv) for ports that
are ready for use.

TERMINATION
The 8260 and 8261 Terminal setting shows if the port is acting as a line termination
(lt) or a network termination (nt). Generally, the line termination resides at the local
central office, while the network termination is located at the customer location.
Changing the termination from nt (the default) to lt on the 8261 BRI card requires
changing jumper settings on the card itself. Instructions for this conversion are
included at the end of this chapter.

Page 8-G-4

(10-97)

Reference Guide v3.6

BRI Card

TYPE
The Type setting determines the type of BRI connection for this port. The options
available are lease (a permanent circuit), brite (BRI Terminal Emulation), iw
(interworking) and ntu_l (Network Terminating Unit - Lease, 8260 and 8261 only).
If ntu_l is selected, the user is required to select either 64 (which corresponds to the
Adtran NTU) or 2560 (which corresponds to the 2560/2561 NTUs). If the wrong type
of NTU is selected, the user will not be able to perform remote configuration of the
NTU.

B MODE
The B Channel Mode option determines the B channel usage for this port. Setting the
port to none tells the system that the equipment associated with this port does not
require a B channel and access to both B WANs is disabled. Setting the highlighted
port to B1 tells the system that only one B channel is required for the BRI equipment.
Selecting B1 enables the B1 WAN and B1 TS and disables the B2 WAN and B2 TS.
Setting the port to B2 tells the system that only one B channel is required for the BRI
equipment. Selecting B2 enables the B2 WAN and B2 TS and disables the B1 WAN
and B1 TS.
Setting the port to B1+B2 tells the system that two B channels are required for the BRI
equipment. Selecting B1+B2 enables both the B1/B2 WANs and TSs. Any WAN and
any timeslot can be assigned to either B channel.
Setting the port to 128K tells the system that a 128Kbps "pipe" is required for the DTE
equipment. Selecting 128K enables both the B1/B2 WANs and TSs. Both B channels
must be assigned to the same WAN.

B1 WAN/SERV
The WAN setting identifies the WAN link for the first B channel assigned to this port.
It is not necessary for all 8 ports on the same card to be assigned to the same WAN link,
or to contiguous time slots on a WAN link. The serv port is set from conVert screen.

B1 TS
The TS setting identifies the time slot on the WAN link for the first B channel assigned
to this port. Values range from 1-24 for T1 links and 1-31 for E1 links. Time slot 16 is
not available on E1 links that are programmed for cas or ccs signaling. For a display of
the available time slots, refer to your cross-connect map for the WAN link. See the
Operations chapter for information about viewing cross-connect maps.

B2 WAN/SERV
The WAN setting identifies the WAN link for the second B channel assigned to this
port. If 128K is selected for the B Mode, the second B channel must be assigned to the
same WAN link as the first B channel.

(10-97)

Page 8-G-5

BRI Card

Reference Guide v3.6

B2 TS
The TS setting identifies the time slot on the WAN link for the second B channel
assigned to this port. Values range from 1-24 for T1 links and 1-31 for E1 links. Time
slot 16 is not available on E1 links that are programmed for cas or ccs signaling.

D WAN
The D WAN setting identifies the WAN link for the D channel assigned to this port for
brite circuits. It is not necessary for all ports on the same card to be assigned to the
same WAN link, or to contiguous time slots on a WAN link.

D TS
The TS setting identifies the time slot on the WAN link for the D channel assigned to
this port for brite circuits. Values range from 1-24 for T1 links and 1-31 for E1 links.
Time slot 16 is not available on E1 links that are programmed for cas or ccs signaling.

D SUBCHAN
The D Subchannel option allows the user to use a full DS0 for the D channel or split the
DS0 into four 16Kbps sections to allow D channels to be combined into a single
64Kbps DS0. D subchannels must be used on the same BRI card only.

LOCAL LB
The Local Loopback setting controls the direction of the local loopback. The settings
are off (for no loopback), ta (for a loopback toward the terminal adapter) and net (for a
loopback toward the network).

LB CHAN
The Loopback Channel setting places the local loopback on either the first B channel
(B1), the second B channel (B2) or both B channels (B1+B2).

LBGEN MD
The Loopback Generation Mode specifies the type of loopback to be placed on the
circuit. The BRI card only generates loopback codes, it does not detect loopback codes.
The options are ddsT (a DDS loopback on the terminal side of the line), ddsN (a DDS
loopback on the network side of the line), v54T (V.54 loopback toward the terminal),
v54N (V.54 loopback toward network), ft1T (a fractional T1 loopback toward the
terminal), ft1N (fractional T1 loopback toward the network) and eoc (Embedded
Operations Channel loopback towards the U interface).

Page 8-G-6

(10-97)

Reference Guide v3.6

BRI Card

LB GEN
The Loopback Generation option specifies different loopback codes depending on the
selection of loopback generation mode above. The options for ddsT and ddsN are off
(no loopback), B1ocu (an OCU loopback on the first B channel), B1csu (a CSU
loopback on the first B channel), B1ds0 (a full DS0 loopback on the first B channel),
B1dsu (a DSU loopback on the first B channel), B2ocu (an OCU loopback on the
second B channel), B2csu (a CSU loopback on the second B channel), B2ds0 (a full
DS0 loopback on the second B channel) and B2dsu (a DSU loopback on the second B
channel).
The options for v.54T, v,54N, ft1T and ft1N are off (no loopback), B1 (v.54 or Ft1
loopback on the first B channel), B2 (v.54 or Ft1 loopback on the second B channel)
and B1+B2 (v.54 or Ft1 loopback on both B channels).
The options for eoc are off (no loopback), B1 (eoc loopback on the first B channel), B2
(eoc loopback on the second B channel), B1+B2 (eoc loopback on the both B channels)
and 2B+D (eoc loopback on the both B channels and the D channel).
If the loopback is directed toward the terminal, the loopback pattern selected will not
start until the U-ST parameter on the test screen shows the status of "actv." (See the
test section below for further information about the U-ST parameter.)

SEAL CURR
Sealing current (on the 8261 card only) is used to inhibit corrosion on wire splices in
outside plant. The Sealing Current option on the BRI card allows the user to select
sealing current on a port-by-port basis.
Jumpers on the card allow the user to choose between a 15mA (the default) or
7.5mA current (provided by the -48VDC power converter). The jumper settings
are shown at the end of this chapter.
The setting for this parameter is n/a for the 8260 card. The settings are no and yes for
the 8261 card. Choosing yes for this setting will automatically bring up the screen of
Figure BRI-3. Table BRI-3 shows the parameter settings and defaults for this screen.

RCVE
The settings are noTst (no code violation test) and cdVol (code violation test). If cdVol
is set and a code violation is detected, the card sends an interrupt toward the network
line.

TR COND
The Trunk condition (TR COND) setting allows the BRI card to pass trunk conditions
from the network to the U/ST interface when set to on. Setting the TR COND state to
off prevents the condition to be passed through the card.

BERT
Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected BRI port. Depending upon whether the test is on B channels or D
channels, the patterns can be sent as either raw data or as HDLC packets containing the
patterns. BERT can only be sent on one port at a time.
For a B channel test, the patterns that can be selected are off, mark (1111), space
(0000), 1:1 (1010), 1:7 (0100-0000), p_1 (packet, 1111), p_0 (packet, 0000), p_1:1
(packet, 1010) and p_1:7 (packet, 0100-0000).
If the D channel is selected, the patterns that can be selected are off, p_1 (packet,
1111), p_0 (packet, 0000), p_1:1 (packet, 1010) and p_1:7 (packet, 0100-0000).

DIR
Selects the direction of the test. The options are ta, toward the Terminal Adapter
(customer site) or net, toward the Network (carrier).

CHAN
Selects the side of the line on which the BER pattern will be sent. The options are B1
(BERT on B channel #1), B2 (BER is on B channel #2), 128K (BERT is on the 128K
pipe) and D (BERT is on the D channel).

SYNC
Synchronization (SYNC) displays yes if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test
equipment, no if it has not.

BE
Bit Error (BE) displays the total number of bit errors logged.

ES
Errored Seconds (ES) displays the total number of seconds in which errors were
detected.

SES
Severely Errored Seconds (SES) shows the total number of seconds in which the bit
error rate exceeded one bit per thousand (1 x 10-3).

(10-97)

Page 8-G-23

BRI Card

Reference Guide v3.6

CSES
Consecutive Severely Errored Seconds (CSES) is triggered by the occurrence of ten
consecutive Severely Errored Seconds. Once triggered, the CSES field will increment
(by one) for each elapsed second until the system logs ten consecutive non-Severely
Errored Seconds.

OSS
Out of Synchronization Seconds (OSS) shows the number of seconds that the BRI
BERT has been out of synchronization.

BER
Bit Error Rate (BER) shows the rate at which errors are being logged. BER equals the
number of bit errors (BE) divided by the total number of bits transmitted during the test.

ELAP
Elapsed time (ELAP) is the total number of seconds elapsed during the test.

U-ST
Displays the status of the U interface ports. Possible U interface states include stdby,
init (initializing), actv, fail (failed to activate), deact (deactivated), nos (no signal), los
(loss of signal), b1eoc (eoc loopback on B1), b2eoc (eoc loopback on B2), 2beoc (eoc
loopback on both B channels), bdeoc (eoc loopback on both B and D channels).
If the LB GEN option (on the previous screen) is set to ta, the U-ST field must show
"actv" before any loopbacks selected become operational.

LB ST
Loopback State (LB STATE) indicates the local loopback selected on the main screen
for this port. Possible states are: off, ta, or net.

SEAL
Indicates if the sealing current is selected or not (8261 BRI Card only).

Performance Monitoring (8260/8261)
The 8260 and 8261 BRI cards support proprietary performance monitoring, which
continuously measures operation performance of the connection from the Integrated
Access Controller to the NTU. Each one hour segment is divided into 3600 seconds
and statistics are kept for the current hour and the past 24 one hour periods.
To get statistics for a particular port, highlight the port on the BRI card main screen and
press the P (Performance Monitoring) key. The screen shown as Figure BRI-10
appears. Table BRI-17 defines the parameters displayed.
While viewing the performance monitoring screen, the user must press the R (refresh)
command from the menu of actions to obtain updated statistics.

STATE
Set the State option to stdby (standby) for ports that are not in use or not yet
configured; set it to actv (active) for ports that are ready for use. The default is stdby.

TERMINAL
The 8262 Terminal setting allows the port to be set as an nt-pp (network termination
point-to-point), nt-sb (network termination short-bus), nt-eb (network termination
extended-bus) or te (terminal equipment) device. The default for the 8262 is nt-pp.

TYPE
The Type setting determines the type of BRI connection for this port. The options
available are lease (a permanent circuit), brite (BRI Terminal Emulation), iw
(interworking) and ntu_l (Network Terminating Unit - Lease, 8260 and 8261 only).

B MODE
Determines the B channel usage for this port. none disables access to both B WANs.
Setting the highlighted port to B1 assigns only one B channel. Selecting B1 enables the
B1 WAN and B1 TS and disables the B2 WAN and B2 TS. Setting the port to B2
enables the B2 WAN and B2 TS and disables the B1 WAN and B1 TS.
Selecting B1+B2 enables both the B1/B2 WANs and TSs. Any WAN and any timeslot
can be assigned to either B channel.
Setting the port to 128K tells the system that a 128kbps "pipe" is required for the DTE
equipment. Selecting 128K enables both the B1/B2 WANs and TSs. Both B channels
must be assigned to the same WAN.

B1 WAN/SRV
The WAN setting identifies the WAN link for the first B channel assigned to this port.
It is not necessary for all 8 ports on the same card to be assigned to the same WAN link,
or to contiguous time slots on a WAN link. The serv port is set from conVert screen.

B1 TS
The TS setting identifies the time slot on the WAN link for the first B channel assigned
to this port. Values range from 1-24 for T1 links and 1-31 for E1 links. Time slot 16 is
not available on E1 links that are programmed for cas or ccs signaling. Use the up and
down arrow keys to scroll through the time slots. For a display of the available time
slots, refer to the cross-connect map for the WAN link. See the Operations chapter for
information about viewing cross-connect maps. There is no assignment to a server.

BRI Card

B2 WAN/SRV
The WAN setting identifies the WAN link for the second B channel assigned to this
port. If 128K is selected for the B Mode, the second B channel must be assigned to the
same WAN link as the first B channel. The serv port is set from conVert screen.

B2 TS
The TS setting identifies the time slot on the WAN link for the second B channel
assigned to this port. Values range from 1-24 for T1 links and 1-31 for E1 links. Time
slot 16 is not available on E1 links that are programmed for cas or ccs signaling. The
up and down arrow keys are used to scroll through the time slots. There is no
assignment to a server.

D WAN
The D WAN setting identifies the WAN link for the D channel assigned to this port for
brite circuits. It is not necessary for all ports on the same card to be assigned to the
same WAN link, or to contiguous time slots on a WAN link.

D TS
The TS setting identifies the time slot on the WAN link for the D channel assigned to
this port for brite circuits. Values range from 1-24 for T1 links and 1-31 for E1 links.
Time slot 16 is not available on E1 links that are programmed for cas or ccs signaling.

D SUBCHAN
The D Subchannel option allows users to employ a full DS0 for the D channel or split
the DS0 into four 16kbps sections to allow D channels to be combined into a single
64kbps DS0. D subchannels must be used on the same BRI card only.

LOCAL LB
The Local Loopback setting controls the direction of the local loopback. The settings
are off (no loopback), ta (loopback toward the terminal adapter) and net (loopback
toward the network).

LB CHAN
The Loopback Channel setting places the local loopback on either B1 (the first B
channel), B2 (the second B channel) or B1+B2 (both B channels).

(10-97)

Page 8-G-31

BRI Card

Reference Guide v3.6

LBGEN MD
The Loopback Generation Mode specifies the type of loopback to be placed on the
circuit. The BRI card only generates loopback codes, it does not detect loopback codes.
The options are ddsT (DDS loopback on the terminal side of the line), ddsN (a DDS
loopback on the network side of the line), v54T (V.54 loopback toward the terminal),
v54N (V.54 loopback toward network), ft1T (fractional T1 loopback toward the
terminal), ft1N (fractional T1 loopback toward the network).

LB GEN
The Loopback Generation option specifies different loopback codes depending on the
selection of loopback generation mode above. The options for ddsT and ddsN are off
(no loopback), B1ocu (an OCU loopback on the first B channel), B1csu (a CSU
loopback on the first B channel), B1ds0 (a full DS0 loopback on the first B channel),
B1dsu (a DSU loopback on the first B channel), B2ocu (an OCU loopback on the
second B channel), B2csu (a CSU loopback on the second B channel), B2ds0 (a full
DS0 loopback on the second B channel) and B2dsu (a DSU loopback on the second B
channel).
The options for v.54T, v.54N, ft1T and ft1N are off (no loopback), B1 (v.54 or Ft1
loopback on the first B channel), B2 (v.54 or Ft1 loopback on the second B channel)
and B1+B2 (v.54 or Ft1 loopback on the both B channels).
If the loopback is directed toward the terminal, the loopback pattern selected will not
start until the U-ST parameter on the test screen shows the status of actv. (See the Test
section for further information about the U-ST parameter).

RCVE
The settings are noTst (no code violation test) and cdVol (code violation test). If cdVol
is set and a code violation is detected, the card sends an interrupt toward the network
line.

TR COND
The Trunk condition (TR COND) setting allows the BRI card to pass trunk conditions
from the network to the U/ST interface when set to on. Setting the TR COND state to
off prevents passing the condition through the card.

BERT
Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected BRI port. Depending upon whether the test is on B channels or D
channels, the patterns can be sent as either raw data or as HDLC packets containing the
patterns. BERT can only be sent on one port at a time.

Page 8-G-34

(10-97)

Reference Guide v3.6

BRI Card

For a B channel test, the patterns that can be selected are off, mark (1111), space
(0000), 1:1 (1010), 1:7 (0100-0000), p_1 (packet, 1111), p_0 (packet, 0000), p_1:1
(packet, 1010) and p_1:7 (packet, 0100-0000).
If the D channel is selected, the patterns that can be selected are off, p_1 (packet,
1111), p_0 (packet, 0000), p_1:1 (packet, 1010) and p_1:7 (packet, 0100-0000).

DIR
Selects the direction of the test. The options are ta, toward the Terminal Adapter
(customer site) or net, toward the Network (carrier).

CHAN
Selects the side of the line on which the BER pattern will be sent. The options are B1
(BERT on B channel #1), B2 (BER is on B channel #2), 128K (BERT is on the 128K
pipe) and D (BERT is on the D channel).

SYNC
Synchronization (SYNC) displays yes if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test
equipment, no if it has not.

BE
Bit Error (BE) displays the total number of bit errors logged.

ES
Errored Seconds (ES) displays the total number of seconds in which errors were
detected.

SES
Severely Errored Seconds (SES) shows the total number of seconds in which the bit
error rate exceeded one bit per thousand (1 x 10-3).

CSES
Consecutive Severely Errored Seconds (CSES) is triggered by the occurrence of ten
consecutive Severely Errored Seconds. Once triggered, the CSES field will increment
(by one) for each elapsed second until the system logs ten consecutive non-Severely
Errored Seconds.

Setting Terminal Type Jumpers on the 8261
Setting or resetting jumpers is necessary for conversion of individual ports on the 8261
from Network Terminal (nt) to Line Terminal (lt). Cards are shipped with Network
Terminal as the default (jumpers closed). To make the conversion, remove the BRI
card from its slot and remove shorting jumpers across the jumpers labeled J101-J801
(the first digit [e.g. 101] is the port number indicator) on both sets of pins next to the
front edge of the card as shown in Figure BRI-13.
Ports can be set individually for the lt feature, but once set, remain in the lt mode until
the jumpers are reattached.

Setting Jumpers on the 8262
As shown in Figure BRI-15, there are 4 jumper options, JPx01, JPx02, JPx03 and
JPx04, for each of the eight (8) BRI ports. (The “x” indicates the numbers 1 through 8.)
Jumpers JPx02, when installed, applies the XMT 100 Ohm termination. Jumpers
JPx03, are installed as the default to apply the RCV 100 Ohm termination. The actual
network design determines the setting of these termination’s.
Jumpers JPx01 and JPx04 are installed (ON) to provide either internal (INT) or
external (EXT) -48v power to the phantom leads based upon the setting of JP5 and JP6
(see markings on the 8262 board). When the JPx01 and JPx04 jumpers are ON, they
provide power out on the cable pair. When OFF, there is no power out on the cable
pair.
The jumper defaults are as follows:
Phantom Power - ON/OFF (Jx01 and Jx04) are default = ON
Phantom Power Source - Int/Ext (JP5 & JP6) are default = External
100 Ohm Term - Xmt OUT, Rcv IN
If external power is used, jumpers JP5 and JP6 must be set to EXTERNAL mode.
Failure to do so could damage or destroy the card or system.

Introduction
This chapter describes the pinouts of the card connectors used to attach circuits and
devices to the integrated access system complex. The front view of the two-sided
chassis is shown in Figure Pinouts-1. The two-sided unit was designed so that all
cabling would be done at the back of the chassis shown in Figure Pinouts-2. All frontloading chassis were designed so that all cabling would be done at the front of the
chassis, as seen in Figure Pinouts-3 through Figure Pinouts-5. The number and type of
connectors needed will vary with the card installed. Each card that requires cabling is
shown in this chapter, the connector is described, and the pinouts labeled.

External Alarm Card (8401 and 8402)
External Alarm cards can be installed in any user card slot, U1-U-8 on the 8918 twosided chassis or 8919 front-loading chassis, and P1-P4 or W1-W4 on the 8916 frontloading chassis. These cards enable the integrated access system to respond to four
external alarms (three alarms for the 8402) for control of environmental and security
conditions, and four internal alarms (three alarms for the 8402) to outside alarm
indicators (for example, a critical alarm lights a red light).
Each inbound alarm sensor has the capability of responding to one external condition.
The alarms appear on the screen in the alarm section, showing the alarm as a SENSOR
alarm and includes the slot number and sensor number of the condition (i.e., SENSOR
U7-4).
The inbound alarm sensors may be optioned to accept either 12 or 48v. Both JP1 and
JP2 jumpers should be set to the proper inbound voltage. The inbound sensors are
isolated from ground.
Each outbound "floating" relay (normally open contacts and normally closed contacts)
responds to system alarm categories (major [major and critical] and minor [minor and
informational]) and activates an external device. There are two relays for each of the
four Alarm Card ports. The relays are dual-pole, double-throw.
The External Alarm Card has an RJ27X (female) 50-pin Amphenol connector located
on the faceplate of the card. Figure Pinouts-13 shows the pinouts for the connector and
Table Pinouts-9 shows the pin assignments for both inbound sensor alarms and
outbound internal alarm indicators.

The jumper pairs that correspond to each sensor are numbered accordingly. For
example, the jumper pairs for sensor #12 are those in row SI12 of the lower jumper
group (columns JP1 and JP2). The jumper pairs that correspond to sensor #25 are those
in row SI25 of the upper jumper group (columns JP3 and JP4).
The outside pin of each jumper pair carries voltage, while the inside pins are passive, as
shown in Figure Pinouts-15. The outside (left) pins for the jumper pairs in columns JP1
and JP3 carry positive (+) voltage, while the outside (right) pins for the jumper pairs in
columns JP2 and JP4 carry negative (-) voltage.
