CHAPTER 1. INTRODUCTION

CHAPTER 1. INTRODUCTION
Overview
This manual provides the procedures and associated forms for collecting system and voice
terminal features. This information is used with AT&T System 75—Administration, 555-200500, to initialize the AT&T System 75 and System 75 XE using the System Access Terminal.
In the planning process, system requirements were identified by the AT&T Account Team
and the customer. Those requirements were converted into orderable system hardware when
the Account Team configured the system.
This manual is solely concerned with AT&T System 75 implementation; that is, the
completion of paper records and forms that are used to initialize and administer the System
75 Release 1 Version 3 or the System 75 XE.
This manual explains the forms required to implement the various system and voice terminal
features. Instructions on how to complete each paper record and form are also provided.
AT&T System 75—Administration, 555-200-500, explains how to use the paper records to
initialize and administer the system.
The chart in Figure 1-1 depicts work activities and relative time frames.
This manual provides the forms and instructions required to implement a System 75 Release
1 Version 3 (RlV3) or a System 75 XE. All forms and features described in this manual apply
to a Release 1 Version 3 System 75 and a System 75 XE unless otherwise noted as V3 or
System 75 XE.
This manual is being reissued to include the following information.
• Add V3 enhancements
Ž Add information for the Hospitality Parameter Reduction feature
• Add 7309H voice terminal
• Provide detailed information on how to implement AUDIX in a DCS or non-DCS
environment.
To complete this manual, you must:
•

Have hardware and feature knowledge (consult AT&T System 75—System
Description, 555-200-200, and AT&T System 75—Feature Description, 555-200-201 )

•

Know what system and terminal hardware has been ordered [refer to the Delivery
Operations Support System (DOSS) order]

CHAPTER 1. INTRODUCTION

Organization
The other chapters in this manual are:
Chapter 2—ARS and Trunks— Instructions and Forms—Lists the forms required to
implement Automatic Route Selection and System 75 trunks.
Chapter 3—Optional Features— Lists the optional features available to System 75 users.
These features are not part of the standard system capabilities and must be purchased
separately.
Chapter 4—Communications Survey—Describes the Communications Survey. This
information is essential to get started with system implementation.
Chapter 5—System Features, Functions, and Services— Provides the instructions required to
implement the system and voice terminal features. Included in each feature description is a
table listing the feature forms required to implement that feature and the page numbers
where they can be found. The blank form page number is also provided.
Chapter 6—System Forms—Contains the feature forms and instructions for completing each
field on the forms. The forms in this part provide an accurate representation of the screen
forms that are displayed on the System Access Terminal (SAT) during system initialization
and on-going administration.
Chapter 7—Blank Forms—Contains a complete set of blank forms. Reproduce these forms
as needed to implement the system.
Chapter 8—References— Provides a list of System 75 reference documentation. A brief
description of each document is included.
Chapter 9—Index—Contains a permuted index.
The information in Chapters 2, 5, and 6 of this manual is valid for adding and changing
features after the system has been initialized. This manual is the only source of a detailed
description of the screen forms and a list of the forms that can be completed for a given
feature.
To use this manual after initialization, the following items should be followed:
1.

1-2

Certain identifiers, such as hunt group number, may be part of the administrative
command instead of an assignable field. For example, assume hunt group 4 is
established (on form for Hunt Group 4) during implementation. The “4” is entered on
the form to identify the hunt group. However, when the system is initialized, the
command add hunt-group 4 is used to access the appropriate screen form for
adding Hunt Group 4. The “4” is already stored in translation for that hunt group.
Similarly, the change hunt-group 4 command is used to make changes on hunt
group 4. A complete list of administrative commands is given in AT&T System 75—
Administration, 555-200-500.

CHAPTER 1. INTRODUCTION

2. Some of the forms listed in Chapter 5 should not be changed frequently. Specifically,
the Dial Plan Record, Feature Related System Parameters, and Feature Access
Codes forms normally do not require changes after initialization. When making
additions or changes to the system, verify the required forms and/or fields have been
completed. Specify the additional data needed to add or change the desired feature.
Many of the forms that appear on the SAT contain dynamic fields. Dynamic fields appear or
disappear on the form depending on how another field is assigned. Dynamic fields are
identified by implementation notes below the form.

How to Use
The procedural checklist in the following steps should be followed to complete the forms in
this manual.
1.

Become familiar with the contents of this manual.

Conduct a Communications Survey.
Survey are in Chapter 4.

Instructions for completing a Communications

3. Using Chapter 5 of this manual as a guide for implementing the desired features
available to System 75 users, complete the forms as shown in Chapters 2 and 6.
Blank forms are in Chapter 7. After these forms have been completed, they should
be used with AT&T System 75—Administration, 555-200-500, to initialize the system.
After initialization, all completed forms should be maintained as a permanent record.

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS AND FORMS

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS
AND FORMS
Overview
This chapter contains the forms and instructions required to assign Automatic Route
Selection (ARS) and System 75 trunks.
The first part of this chapter covers ARS. The second part covers the System 75 trunks.
The blank forms for ARS and trunks are in Chapter 7. Reproduce a blank form for the ARS
and trunk forms being used.

Automatic Route Selection
ARS routes calls over the public network based on the preferred (normally the least
expensive) route available at the time the call is placed. ARS provides a choice of up to six
routes from any given public network call. The following types of trunk groups can be
accessed by ARS:
•

Local central office—Used for local calls and to provide access to long-distance
carrier. Access to the long-distance carrier can be provided automatically by the
central office or by a carrier access code.

•

Foreign exchange—Used to emulate local calling in an area served by the local
central office.

•

Wide Area Telecommunications Service (WATS)—Used to provide calling to
predefine geographic areas at a rate based on expected usage.

•

Tie trunks—Used to provide access to an Electronic Tandem Network (ETN), or to
an Enhanced Private Switched Communications Service (EPSCS) or Common Control
Switching Arrangement (CCSA) office.

The following forms are used to assign ARS features:
Ž ARS Foreign Numbering Plan Area (FNPA)
• ARS Home Numbering Plan Area (HNPA)
Ž ARS Remote Home Numbering Plan Area (RHNPA)
• ARS Toll Table
• Code Restriction FNPA

ARS—Foreign Numbering Plan Area (FNPA)

Automatic Route Selection—Foreign Numbering Plan Area (FNPA)
Purpose
This form is used to assign the routing pattern associated with each FNPA. The ARS FNPA
table points to the appropriate Routing Pattern for each nonlocal NPA or points to a 6-digit
translator so the call will be routed on both the NPA and the office code.
Although they are not FNPAs, the codes 00x, 01x, 10x, and 11x (where x is a number 0
through 9) can be assigned for routing calls beginning with these digits.
The system recognizes certain types of dialing patterns on outgoing calls and routes these
calls via special entries in the FNPA or HNPA table. Table 2-A lists the special dialing
patterns along with the associated FNPA or HNPA table entry through which that type of call
is routed.

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS AND FORMS

Typical assignments for the FNPA Table are as follows:
—

"H" —pattern/table assignment for the HNPA

—

"R"(1-32)—office code translation of a given NPA and Pattern Numbers

Patterns should be created to accommodate individual customer needs. Careful application
of this table permits Automatic Route Selection for all types of calling including IDDD
(International Direct Distance Dialing) and carriers other than AT&T.
Instructions
Make assignments as required for the following fields:
• Partitioned Group Number—Enter a group number from 1 through 4.
Ž Pattern Choice Assignments— For the x00 through x19 fields in each FNPA block
(000-019 through 900-919), enter a number from 1 through 254 for the desired
pattern number or a number from 1 through 32 preceded by “r” (for example, r1, r15,
r32) for the desired RHNPA Table Number. Enter “h” or “H” as the pattern number
for the Iocal(home) NPA to indicate that this NPA is the HNPA rather than an FNPA.

ARS—Home Numbering Plan Area (HNPA)

Automatic Route Selection—Home Numbering Plan Area (HNPA)
Purpose
This form is used to assign the routing pattern associated with each of the 800 office codes
in the local area code. The ARS HNPA Table points to the appropriate routing pattern for
each office code within the home NPA.
The default value for all 800 office codes is pattern 1. Normally, pattern 1 should be used as
the HNPA toll pattern because in most NPAs there are more toll offices than local office
codes. This will minimize the number of changes required to complete the form.
Instructions
Make assignments, as required, for the following fields:
• OFFICE CODE—Enter a hundreds block; that is, 200-299 through 900-999.
●

Partitioned Group Number—Enter a group number from 1 through 4.

• Pattern Choice Assignments— Enter a pattern number from 1 through 254.

ARS—Remote Home Numbering Plan Area (RHNPA)

Automatic Route Selection—Remote Home Numbering Plan Area (RHNPA)
Purpose
This form is used to assign office codes and the associated routing pattern number for 32
selected RHNPAs. One form is required for each block of 100 central office codes.
RHNPAs are referenced from the FNPA Table and are commonly referred to as “6-digit
translators.”
The RHNPA Table provides a choice of up to 12 routing patterns for each block of 100
central office codes, whereas the HNPA Table provides a choice of 254 routing patterns for
each office code.
Instructions
Make assignments as required for the following fields:
•

ARS RHNPA TABLE—Enter the applicable table number from 1 through 32. Up to
eight forms may be required for each table, one for each hundreds block, 2 through
9.

•

OFFICE CODE—Enter the desired hundreds block; that is, 200-299 through 900-999.
A separate form is required for each hundreds block.

•

Pattern Choices—Enter a pattern number from 1 through 254 representing the
Routing Patterns that can be accessed by the RHNPAs identified on this screen form
only. Each screen form on each RHNPA table may have 12 different Pattern
Choices. Patterns listed on one screen form do not automatically default to the other
forms of the same table. If one pattern will be used most often (that is, accessed by
the greatest number of office codes in this block), assign that pattern as choice 1.
Otherwise, the correlation between Pattern Choice numbers and Patterns is
completely arbitrary.

•

Office Code—Pattern Choice Assignments (from 1-12 above)—Enter a Pattern
Choice number from the list above in the field associated with each Office Code. The
Office Code fields represent the last two digits of the codes within the hundreds
block. The Pattern Choice Assignment points to the Pattern Choice, above, that
contains the Routing Pattern to be used.

Instructions
Make assignments as required for the following fields:
Ž Area Code—Enter the Home Numbering Plan Area of the PBX,
Ž

ARS Prefix 1 Required—Enter “y” if the user is required to dial 1 to indicate a 10digit toll call. This is required when the PBX is located within an area code that
contains a Central Office Code resembling an area code. These are the following:
— 201 in New Jersey
— 212 in New York
— 213 in Los Angeles
— 312 in Chicago
— 706 in Northwest Mexico
— 905 in Mexico City
The following paragraphs show how dialed numbers are interpreted by the system if
"y" is assigned to the ARS Prefix 1 Required, field. The number 9 represents the
ARS Access Code.
— 9+1+(212)-201-1234 infers a 10-digit toll call.
— 9+(212)-201-1234 infers that 212 is a Central Office Code. The system
accepts only the first seven digits following the ARS Access Code. The
number 212-2011 is sent to the Central Office.
— 9+201-1234 infers a 7-digit call within the HNPA.
— 9+1+201-1234 infers the first seven digits of a 10-digit toil call and waits for
the remaining three digits. The number being outpulsed is (201)-123-4xxx.
If the number being dialed is a toll call within the HNPA and the Central Office
Code resembles an area code as in the example above, then the HNPA must
also be included in the number dialed (refer to the first example).
— 9+922-1234 or 9+1+922-1234 infers a 7-digit call (or toll call) within the
HNPA. This example differs from the preceding example in that the Central
office Code (922) does not resemble an area code.

Trunk Characteristics
A trunk is named for its transmission characteristics and can be analog or digital depending
on the type of signals it carries. One transmission characteristic is signaling. Signaling is
the transmission of supervision, address, alerting, or other switching information between
switches.

2-26

General

A trunk is further classified as one of the following:
• 1-way incoming trunk— A local trunk that can be selected (seized) by the far-end
connected switch.
• 1-way outgoing trunk— A trunk that can be seized by the local switch to call the farend switch.
• 2-way trunk —A trunk that can be seized at either end of the connected switches.

Transmission of Supervision
One of four types of supervision signaling is used in trunks. These four types are:
•

E & M (Ear & Mouth) supervision—A symmetric signaling scheme used on private
network trunks in which dc voltage levels are sent over E and M leads. The E and M
leads are separate from the transmission path (T & R leads). E & M signals indicate
on-/off-hook states of each end of the connection path. E & M signaling is further
divided into types (Type I through V). DIMENSION® PBX systems use only Type I
and System 75 and System 85 can use Type I or V. Type I is signaling from the trunk
interface to the far-end over the M lead using nominal -48 volts for off-hook and local
ground for on-hook. Signaling from the far-end is over the E lead using far-end
ground for off-hook and open for on-hook. Type V is signaling in both directions by
means of open for on-hook and ground for off-hook.

• GS (Ground Start) supervision— A supervisory signaling scheme used on public
network trunks in which ground is applied on the Tip (T) lead by the CO, and on the
Ring (R) lead by the PBX. For example, the calling PBX on a call to a central office
using an outgoing trunk interface seizes the outgoing trunk by placing a ground on
the trunk interface R lead. The CO recognizes the trunk seizure as a request for
service and grounds the trunk T lead to indicate to the calling PBX that the CO is
ready to receive digits.
•

LS (Loop Start) supervision—A supervisory signaling scheme used between a voice
terminal and a PBX in which the voice terminal completes the loop current path. The
loop current path is completed with the addition of battery polarity reversal used for
answer supervision and a positive/negative 130-V dc signal applied from ground to
both tip and ring conductors.

•

RB (Reverse Battery) supervision—A supervisory technique on 1-way trunks that
uses open and closure signals from the originating end and reversals of battery and
ground from the terminating end (normally used on direct inward dialing trunks).

Transmission of Address
With signaling there are three types of transmission of address. Transmission of address is
the method of signaling used to represent digits and/or characters for called numbers, calling
numbers, etc. The methods of addressing are dial pulse (DP), dual tone multifrequency
(DTMF), and multifrequency (MF) addressing.

2-27

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS AND FORMS

• DP addressing —A means of signaling that consists of regular momentary
interruptions of a direct or alternating current at the sending end in which the number
of interruptions corresponds to the value of a digit or character (alternating current is
not used by PBXs). The interruptions are usually produced by a rotary telephone
dial, or may be produced by a sender in a switching system.
Ž

DTMF addressing—Signaling arrangements (commonly known as touch-tone) consist
of dialing signals of two simultaneous tones. One tone from a low group of four
frequencies and the other from a high group of four frequencies correspond to digits,
letters, or characters (0 through 9, A through Y, or * and #). One of the tones (1633
Hz) from the high group is a spare.

•

MF addressing— Signaling arrangements that make use of two frequencies, and only
two, out of six to represent ten decimal digits (0 through 9) and five auxiliary signals.
MF signals are used for called number addressing, calling number identification,
ringback, and coin control.

Transmission of Alerting
Network trunks operate as automatic, immediate start, dial tone, wink start, or delay dial
according to the type of start dial signal (alerting) the switch sends out or expects to receive.
The different transmissions of alerting are as follows:
• Automatic—The originating switch sends no digits or start dial signal, expecting the
terminating switch to complete the call. The call is usually completed by the attendant
or other service such as Centralized Attendant Service (CAS).
•

Immediate start-The originating switch sends digits immediately, without waiting for
a start dial signal from the terminating switch.

•

Dial tone—The terminating switch sends precise dial tone to the originating switch,
indicating that the terminating switch is ready to receive digits.

Ž Wink start-The terminating switch sends a wink start (momentary off-hook) signal to
the originating switch, indicating that the terminating switch is ready to receive digits.
•

Delay dial—The terminating switch sends a delay dial signal (an off-hook signal
followed by an on-hook signal) to the originating switch, indicating that the
terminating switch is ready to receive digits.

With digital trunks, signaling schemes are basically the same as for analog trunks when
establishing a call. Supervisory, addressing, and alerting have been carried over to the
digital trunks. These schemes are handled in a variety of ways to indicate particular calling
states, such as on-hook, off-hook, ringing, not ringing, etc., by using “A” and “B” bit timed
signaling. “A” and “B” bits carry a 0 or 1 depending on the type of trunk, the near-end
channel unit type, far-end channel type, trunk condition (open loop, loop closure, reverse
battery, etc.), and whether it is transmit or receive signaling.

2-28

General

In addition to the preceding, refer to the DS1 Circuit Pack coverage (Chapter 5) for trunkrelated terms associated with DS1 trunk interfaces.
Private Network Trunks
Priate network trunks are referred to as tie trunks. The tie trunks that interconnect the
switches of a private network are “universal” which means that the trunks can be
administered with a variety of translation encodes. The originating switch can recognize any
start dial signal (precise dial tone, wink start, or delay dial) that the terminating switch sends.
If the originating switch does not receive one of these start dial signals, it can be
administered to send digits after an administered time-out interval. The time-out interval is
the amount of time the originating switch waits before sending digits.
Tie trunks are further classified according to the type of signal (analog or digital) they carry.
Analog Tie Trunks
Analog tie trunks are communications paths that carry voice and voiceband data
communication. The term voice implies that sound is transferred into electrical form and
transmitted within an approximate voiceband of 300 Hz to 3400 Hz. Voiceband data implies
that data is transmitted within the voiceband and requires a conversion resource (modem) at
both ends of the connection. The data transmission rate for analog tie trunks depends on
the data-handling capability of the modems in the connection. Other factors that affect the
data rate are the number of tie trunks in the connection and the technology of any multiplex
systems used in the facilities. Generally, for data rates up to 300 bps, a connection can have
five tie trunks in tandem. For data rates greater than 300 bps up to 2400 bps, a connection
can have up to three tie trunks in tandem. For data rates greater than 2400 bps up to 4800
bps, a connection can have up to two tie trunks in tandem.
Analog tie trunks used in unstitched connections can support up to 9600 bps.
A special type of private network tie trunk is a Release Link Trunk. The Release Link Trunk
(RLT) is used between a central or main location and a branch location to provide
Centralized Attendant Service (CAS). It functions as a 1-way outgoing circuit from the branch
locations and a 1-way incoming to the main location. RLTs participate in the redirection of
incoming calls originally directed to the branch location to attendants at the main location and
handle call completion back to the branch location.
Another special type of trunk is the Advanced Private Line Termination (APLT) trunk. APLT
provides access to and termination from central office based private networks, namely,
Common Control Switching Arrangements (CCSA) and Enhanced Private Switched
Communications Service (EPSCS). APLT trunks are physically the same as those used for
analog tie trunks where the trunk signaling is compatible with EPSCS and CCSA network
switches. The outgoing APLT trunk repeats any number of digits to the private network as
dialed. APLT trunks can tandem through the PBX from EPSCS network only, whereas CCSA
networks require an attendant to complete the call.

2-29

CHAPTER 2. ARS AND TRUNKS—INSTRUCTIONS AND FORMS

Digital Tie Trunk (DS1 )
The digital tie trunk is a high-speed and a high-volume trunk interface to T1 carrier. It uses
digital signal (DS1 ) on the T1 carrier. By multiplexing twenty-four 64-kbps digital channels
onto a single 1.544-Mbps T1 carrier, DS1 offers an economical alternative to the analog tie
trunk as well as a high-speed fully digital (without modems) connection between the
switches.
The maximum per-channel data rate for DS1 is 64 kbps, and it can carry voice, voiceband
data, or high-speed data communications.
The DS1 tie trunk is also used for Digital Multiplexed Interface (DMI). DMI provides highspeed communications over digital transmission facilities between a host computer and
System 75 or System 85. The DMI trunk uses the “A” bit for signaling to provide wink-start
dial-repeating into the switch and automatic out or 2-way wink start.
Public Network Trunks
Public network trunks are classified according to the type of signal (analog or digital) they
carry. Public network trunks are used to connect a private network switch to a public
network switch (central office). In reference to a central office, the term “local” applies to a
switch within the local exchange area. An exchange area has a single uniform set of charges
for telephone service and may be served by more than one central office (CO). Within an
exchange area, a call between any two points is a local call.
Public network trunks also function as “special access” to AT&T Communications (AT&T-C)
toll network. AT&T-C provides such services as MEGACOM@ service, MEGACOM 800
service, and ACCUNET® digital service.
Analog Trunks
Analog public network trunks are as follows:
• Central Office (CO) Trunk—A 1-way outgoing, 1-way incoming, or 2-way trunk
connecting the switch to a CO within the local exchange area.
• Foreign Exchange (FX) Trunk —A 1-way outgoing, 1-way incoming, or 2-way trunk
connecting the switch to a CO that is outside the local exchange area. These trunks
give a caller direct access to a CO outside the local exchange area without having to
use the public network.
• Wide Area Telecommunications Service (WATS) Trunk—A 1 -way outgoing or 1 -way
incoming trunk connecting the switch to a CO equipped to handle WATS calls. The
outgoing trunks allow a customer, for a monthly charge, to place outgoing station-tostation calls to telephones in a defined service area. The service area has one or
more geographic areas known as WATS bands. Incoming trunk calls are completed
by the attendant or other service.

2-30

•

800 Service Trunk—A 1-way incoming trunk connecting the switch to a CO equipped
to handle 800 Service calls (also known as Inward WATS). These trunks allow a
customer, for a monthly charge, to receive incoming station-to-station calls from
telephones in a defined service area without charge to the caller.

•

Direct Inward Dialing (DID) Trunk—A 1-way incoming trunk connecting the switch to
a local CO. These trunks allow calls from the public network to complete to terminals
(stations) assigned to a private network switch without attendant assistance.

•

Direct Outward Dialing (DOD) Trunk—A 1-way outgoing trunk for outgoing calls
connecting the switch to a CO. These trunks allow voice terminal (station) users to
place calls to a public network CO directly (without attendant assistance).

Digital Trunks
The digital public network trunk provides a DS1 interface to the CO over T1 carrier. The DS1
public network trunk provides an interface to CO, FX, WATS, and DID. These trunks provide
loop-start and ground start switch CO, FX, and WATS incoming/outgoing type trunks, and
reverse battery DID trunks. The DS1 interface also allows the assignment of several trunk
types with varying characteristics to the same trunk interface. Therefore, it may also connect
the switch to a toll office directly using wink start tie trunks for 2-way access to the toll
network.

Queue Length—Enter a number from 0 through 100 that indicates the number of
outgoing calls that can be held waiting. A 0 indicates no calls will be held in queue.

•

Abandoned Call Search—Indicate if the trunk group will conduct an Abandoned Call
Search (ACS) to identify a ghost call on a ground-start trunk group. Allowable entries
are “y” or “n. ”

•

Incoming Destination— Indicate where incoming calls will terminate. Allowable
entries are a remote access extension number, 0 (attendant), blank, regular extension
number, announcement, or extension number. If 0 is entered, the call is treated as a
Listed Directory Number (LDN) call. This field must be left blank if the trunk is
automatic on the incoming side.

Comm Type—Indicate if the trunk group is to be used for voice, data, or alternate
voice data calls. Allowable entries are avd, voice, or data. AVD means the trunk
group can be used for both voice and digital applications.

Auth Code—Enter “y” if an authorization code must be dialed to complete incoming
calls on the trunk group; otherwise, enter “n.” This field is displayed if “two-way” or
“outgoing” is entered in the Direction field on the trunk group.

•

Digit Absorption List—Enter a list number from 0 through 4 that is required when the
trunk group terminates at a step-by-step central office. One list is used for each
trunk group that is connected to a step-by-step office.

Prefix-1 —Indicate if the prefix 1 is required for area code calls. The prefix 1
distinguishes between area and local office codes. Allowable entries are “y” or “n.”

•

Restriction—Each CO trunk group may be assigned as toll or code. Toll Restriction
restricts callers at specified voice terminals from placing toll calls without attendant
assistance. An Allowed Calls List is associated with Toll Restriction. Up to 10 Area
codes and/or Central Office codes can be allowed. Code Restriction allows voice
terminal users to place calls from authorized extension numbers to specified Central
Office numbers, Area codes, and special Service codes. Toll Restriction and Code
Restriction cannot be used together in the same trunk group. Leave this field blank
for automatic CO trunks. Allowable entries are toll, code, or blank. This field should
be left blank for automatic CO trunks.

Allowed Calls List—Contains the Central Office codes, Foreign Exchange codes, and
Service codes that can be dialed independently of the 0/1 toll restriction. Allowable
entries are “y” or “n. ” This field appears if “toll” is entered in the restriction field.

Trunk Type—Identify the physical type of trunk. Allowable entries are ground-start,
loop-start, auto/immed, auto/wink, auto/delay, and auto/auto.

Central Office Trunk Group

•

Outgoing Dial Type— Identify the type of pulsing required on an outgoing call.
Allowable entries are tone, rotary, or automatic.

Trunk Termination—Define how the trunk group is terminated. The System 75 trunk
group can terminate in a resistance of 600 ohms, or a resistor capacitor (rc) network.
Allowable entries are 600ohm or rc; rc is used for long loops and 600ohm is used for
short loops. Resistor Capacitor (rc) is the recommended entry. The 600ohm value is
necessary for connection to Customer Premises Facility Terminating equipment
(short loop) and for voice transmission associated with low frequency return loss
requirements.

Disconnect Timing (msec)—Enter the time in milliseconds that is required by the
central office to idle its facilities after it receives a disconnect signal from the System
75. The time interval must be in increments of 10 (from 140 through 2550
milliseconds). Enter 500 unless the trunk is connected to a step-by-step office.
Enter 200 if the trunk is connected to a step-by-step office.

•

ACA Assignment?—Specify whether or not Automatic Circuit Assurance (ACA)
measurements will be taken for this trunk group. Allowable entries are y or n. If “y”
is entered, complete the next three fields.

•

Long Holding Time (hours)—Enter the length in hours that the system will consider
as being a long holding time. If “0” is entered, the system will not consider long
holding calls. Allowable entries are 0 through 10.

•

Short Holding Time (secs.)—Specify the length in seconds that the system will
consider as being a short holding time. If “0” is entered, the system will not
consider short holding calls. Allowable entries are 0 through 160.

•

Short Holding Threshold—Enter the number of times that the system will record a
short holding call before an attendant or display-equipped voice terminal user is
alerted to the possibility of a faulty trunk. Allowable entries are 0 through 30.

Maintenance Tests—Indicate if maintenance tests will be made on this trunk group.
Allowable entries are “y” or “n”.

Answer Supervision Timeout—Indicate the amount of time in seconds the system
allows before beginning an SMDR record of a call. This interval begins as soon as
the outgoing trunk is seized. Allowable entries are 1 through 300 or blank. This
time-out accommodates delays in outside stitchings. This time-out does not
override network or firmware sent answer supervision. For ground-start or loop-start
trunks, the Answer Supervision Timeout field will set the firmware answer supervision
time-out. If this field is left blank, the firmware answer supervision time-out will be set
to a default time of 10 seconds.

•

Suppress # Outpulsing— Enter “y” to indicate end-to-end signaling begins with (and
includes) the “#.”

•

Port-Enter one letter and a 4-digit number. A port number must be assigned for
each member in the trunk group. Refer to Port Assignment Record. Allowable
entries are one letter and four digits.

Type—Specify the type of trunk used. Allowable entries are “t1 stan” (Type 1
Standard), “t1 comp” (Type 1 Compatible), or “type 5.”

• Answer Delay—Specify the length of the answer delay in milliseconds. Allowable
entries are 20 through 5100 in increments of 20. Used to delay the up-link Answer
message. This serves three functions: (1) to assure that the answer supervision
signal is valid and not a secondary delay-dial or wink-start signal, (2) to bridge over
momentary off-hook signals resulting from connections made off-network through
certain crossbar switches as the connection is being established, and (3) to delay cut
through in release link trunk applications so the central attendant does not miss call
progress tones.

CHAPTER 4. COMMUNICATIONS SURVEY

CHAPTER 4. COMMUNICATIONS SURVEY
Overview
This chapter describes the Communications Survey that consists of gathering information
about the System 75, its users, their job functions, and their communications needs. After
this information is identified, it is then matched with the features and hardware available with
the system to design a system that fulfills customer requirements.
Basically, the survey:
Ž Identifies the appropriate features and calling privileges for each user
Ž Assigns appropriate data on hard copy forms that subsequently become part of the
System 75 software data base.

Survey Steps
The steps required to complete the Communications Survey must be done in a logical and
structured way. Complete each of the survey steps in the order given. Some steps are best
performed by a cooperative effort between the account team and the customer or customer’s
representative. Where applicable, these steps are so indicated.
Before actually beginning the survey, review the information provided in Chapter 5 (System
Features, Functions, and Services) and Chapter 6 (System Forms and Instructions). Chapter
5 contains a brief description of the system and voice terminal features. The associated
forms and the fields to be completed on each form are given. Hardware and software
requirements are noted where applicable. You will be required to complete various forms
based on the features to be provided. Chapter 6 contains forms and instructions for
completing each field on a form. Blank forms suitable for reproduction are provided in
Chapter 7.
Review Chapters 5 and 6 several times until you become familiar with the features, the forms
required, and the data to be entered on the forms. The following documents provide
additional information:
Ž AT&T System 75—System Description, Release 1 Version 3, 555-200-200
Ž AT&T System 75 XE—System Description, 555-201-200
Ž AT&T System 75—Feature Description, 555-200-201
Ž AT&T System 75—Planning/Configuration, 555-200-600

4-1

CHAPTER 4. COMMUNICATIONS SURVEY

Step 1—(Account Team)
Obtain a list of equipment (including number and type) that has been ordered for the system.
Identify the system model ordered.
Find out what features and services are to be provided.

Step 2—Port Assignments (Account Team/Client)
This step contains the Port Assignment procedures for a System 75 and System 75 XE
Release 1 Version 3 system.
Port assignments play an important role in how a System 75 is initialized and administered.
Ports are the physical location on a circuit pack where terminals, trunks, or system adjuncts
are connected. Once a port number is assigned, it becomes the “address” of the associated
equipment or facility in the System 75. A record of port assignments must be made and
kept. The record will eventually be used for system installation/initialization and ongoing
administration.
During the planning/configuration process, the types and quantities of circuit packs to be
provided with the system were identified. This information must now be entered on the Port
Assignment Records. Using the list of hardware types and quantities obtained, complete the
Port Assignment Records.
Port Assignment Records
Since the System 75 is available in several different models, the circuit pack slot availability
on the different carriers also varies. Refer to Figure 4-1 for information on the model/carrier
configurations. In addition, Figures 4-2 and 4-3 provide carrier mounting information in the
system cabinet per model number. You will be required to use this information when
completing the Port Assignment Records.
Remove the blank Port Assignment Record forms (Figures 4-4 and 4-5) and duplicate as
many times as necessary to have enough pages for each type carrier (System 75) or cabinet
(System 75 XE) and associated circuit packs to be assigned in the system. A blank Port
Assignment Record for eight ports (Figure 4-4) is required for all circuit packs that contain up
to eight ports. Each 8-port record provides assignment space for four slots on a carrier
(System 75) or cabinet (System 75 XE). A blank Port Assignment Record for 24 ports (Figure
4-5) is required for each carrier slot that will house circuit packs that contain more than eight
ports; for example, the TN722 DS1 Tie Trunk or TN746 Analog Line circuit pack.
Obtain sets of blank records for all control and port carriers to be used.

Survey Steps

System 75 Port Assignment Records
Note:

Instructions for completing System 75 XE Port Assignment Records are
provided immediately following the System 75 Port Assignment Records
instructions.

With a set of records for a carrier, following the “CARRIER” entry at the top of the
Port Assignment Record form, enter the following carrier information as applicable:
• Enter the letter “A” for all control carriers.
Ž Assign a letter (B, C, D, or E) to all records for each Port Carrier. Use the
letter as noted on Figure 4-2 for the Port Carrier location in the System 75
cabinet.

2. Assign port circuit pack slot numbers on the sets of records as follows (refer to
Table 4-A for circuit pack port slot availability and associated notes where
applicable):
Ž

For Control Carrier Models 1A or 1B, begin with slot number 2 and number
through 12.

For control Carrier Models 2A, 2B, 3A, 3B, 3C, and 3D, begin with slot
number 2 and number through 8.

•

All Port Carriers (B, C, D, E) slots should be numbered 1 through 20.

Note: While the System 75 is designed to allow any port circuit pack to be
mounted in any port slot, the following guidelines enhance system
reliability by reducing the size of failure groups as well as by evenly
distributing the system power load across power supplies.
The port circuit packs must be evenly distributed across the system Control and Port
carrier’s. The required sequence for loading carriers with port circuit packs is shown
in Table 4-B.

Certain circuit packs must be installed in dedicated slots on carriers, such as the
TN755 Power Unit. When these circuit packs are used, assign them to slots on the
appropriate Port Assignments Record as shown on Table 4-C. Identify on Table 4-C
the remaining circuit packs that are to be used. Assign the first circuit pack, of that
code, to the appropriate slot on the “A” Port Assignment Record starting with the
rightmost or leftmost port slot as indicated on the table. (Slot numbers are assigned
from left to right on all carriers.)
Note:

The following assumes all cabinet positions (A through E) are used.
For smaller systems, assign circuit packs just to those carriers and
their associated Port Assignment Records that are used.

Assign the second circuit pack of that code (when used) to the rightmost or leftmost
port slot on the “B” Port Assignment Record, the third circuit pack (when used) to
the “C” Port Assignment Record, the fourth circuit pack (when used) to the “D” Port
Port Assignment Record, and the fifth circuit pack (when used) to the “E” Port
Assignment Record. When there are more circuit packs of one code than there are
carriers (Control and Port), the process begins again using the Port Assignment
Record for the next carrier in the Carrier Loading Order. When a Port Assignment
Record for an associated carrier is full, it is skipped over and the process continues
with the next Port Assignment Record in the sequence.
When all the circuit packs of a particular code are assigned, the next circuit pack of a
new code that is used is assigned on the next Port Assignment Record. The process
does not begin again on the “A” Port Assignment Record. For example, when
assigning TN742 Analog Line circuit packs and the last circuit pack was assigned on
the “C” Port Assignment Record, assign the first TN763B Auxiliary Trunk circuit pack
on the “D” Port assignment Record, not the “A” Port Assignment Record.
Any empty slots remaining in any carrier must be equipped with Z100A Apparatus
Blanks.

Only one TN750 Announcement circuit pack may be assigned in a System 75. It must be
installed in the Control Carrier.
There is a maximum of ten TN746 Analog Line circuit packs that may be assigned in any
Port Carrier. These ten circuit packs do not have to be assigned into half-carrier groups.
The Control Carrier(s) can have up to four TN746s each.

Use Table 4-A and identify how many ports are available on each type of circuit pack.
If a circuit pack contains less than eight ports, strike out (do not use) the unavailable
slots on the Port Assignment Record associated with that circuit pack.
Some of the system forms you will later be completing require port information.
When completing such a form, first determine the type circuit pack that is required.
(The type circuit pack for each feature, where required, is identified in Chapter 5,
System Features, Functions, and Services.) Obtain the Port Assignment Record and
select the next available vacant port on the appropriate circuit pack. Then, complete
the following Port Assignment Record items, as required.

System 75 XE Port Assignment Records
Port assignments play an important role in how a System 75 XE is initialized and
administered. Ports are the physical location on a circuit pack where terminals, trunks, or
system adjuncts are connected. Once a port number is assigned, it becomes the “address”
of the associated equipment or facility in the System 75 XE. A record must be made and

CHAPTER 4. COMMUNICATIONS SURVEY

Refer to Figures 4-6 and 4-7 for information on cabinet configurations and mountings. You
will be required to use this information when completing the Port Assignment Records.
Remove the blank Port Assignment Record forms (see Figures 4-4 and 4-5) and duplicate as
many times as necessary in order to have enough pages for each carrier in the system. A
blank Port Assignment Record for eight ports (Figure 4-4) is required for all circuit packs that
contain up to eight ports. Each 8-port assignment record provides assignment space for
four slots on a carrier. A blank Port Assignment Record for 24 ports (Figure 4-5) is required
for each carrier slot that will house circuit packs that contain more than eight ports, for
example, the DS1 Tie Trunk circuit pack.
1. With a set of records for a System 75 XE cabinet—following the “CARRIER” entry at
the top of the Port Assignment Record form, enter the “CARRIER.”
Ž Enter the letter “A” for the Control Cabinet.
Ž Assign a letter (B, C, or D) to all records for each Port Cabinet. Use the letter
as noted on Figure 4-6 for the Port Cabinet location in a multiple System 75
XE port cabinet configuration.
2. Assign port circuit pack slot numbers on the sets of records as follows (refer to
Table 4-D for circuit pack port slot availability and associated notes where
applicable):
• For Control Cabinet, begin with slot number 1 and number through 14.
• All Port Cabinets (B, C, or D) slots should be numbered 1 through 18.
All models come equipped with a TN748C Tone Detector circuit pack in slot 1 for
Port Cabinets B and C. If a TN741 circuit pack is used, then an additional TN748C
circuit pack will be placed in AO1. These circuit packs may be installed in any slot on
the cabinets, but it is recommended that they remain in their provided locations. No
administration is required for the Tone Detector circuit packs.

3. Next, assign circuit packs, if provided, to available slots using the following method:
Note:

While the System 75 XE is designed to allow any port circuit pack to
be mounted in any port slot, the following guidelines enhance system
reliability by reducing the size of failure groups as well as by evenly
distributing the system power load across power supplies.

The port circuit packs must be evenly distributed across the system Control and Port
cabinets. The required sequence for loading cabinets with port circuit packs is
shown in Table 4-E.

Certain circuit packs must be installed in dedicated slots on cabinets, such as the
TN755 Power Unit. When these circuit packs are used, assign them to slots on the
appropriate Port Assignments Record as shown on Table 4-F. Identify on Table 4-F
the remaining circuit packs that are to be used. Assign the first circuit pack, of that
code, to the appropriate slot on the “A” Port Assignment Record starting with the
rightmost or leftmost port slot as indicated on the table. (Slot numbers are assigned
from left to right on all cabinets.)
Note:

The following assumes all cabinet positions (A through D) are used.
For smaller systems, assign circuit packs to just those cabinets and
their associated Port Assignment Records that are used.

Assign the second circuit pack of that code (when used) to the rightmost or leftmost
port slot on the “B” Port Assignment Record, the third circuit pack (when used) to
the “C” Port Assignment Record, and the fourth circuit pack (when used) to the “D”
Port Assignment Record. When there are more circuit packs of one code than there
are cabinets (Control and Port), the process begins again using the Port Assignment
Record for the next cabinet in the Cabinet Loading Order. When a Port Assignment
Record for an associated cabinet is full, it is skipped over and the process continues
with the next Port Assignment Record in the sequence.
When all the circuit packs of a particular code are assigned, the next circuit pack of a
new code that is used is assigned on the next Port Assignment Record. The process
does not begin again on the “A” Port Assignment Record. For example, when
assigning TN742 Analog Line circuit packs and the last circuit pack was assigned on
the “C” Port Assignment Record, assign the first TN763B Auxiliary Trunk circuit pack
on the “D” Port Assignment Record, not the “A” Port Assignment Record.

Once the preceding information has been entered on the Port Assignment Record, enter the
port number on the system form you are completing. The port number consists of the letter
assigned the cabinet and four numbers that consist of the slot number (01 to 18) and the port
number (01 to 08 or 01 to 24). A0208 is a port number example for a single cabinet system
(Control Cabinet only) with a circuit pack mounted in slot 02 with port 08 assigned.

Step 3—Complete Circuit Pack Forms (Account Team/Client)
Note:

The Circuit Pack forms do not have to be completed if the System 75 cabinet
is equipped with the circuit packs at the time of administration.

The Circuit Pack form allows the user to administer circuit packs to carrier slots before the
circuit packs are actually installed in the carrier or cabinet. This then allows the system to be
configured (administered) when the circuit packs have not yet been physically inserted in
their appropriate slots. In order for any end equipment (voice terminals, data terminals, etc.)
to be translated into the system, either a circuit pack must be physically inserted in the
appropriate slot or must be logically installed using the Circuit Pack form. The number of
Circuit Pack forms and associated pages to be completed is dependent on the system
configuration; for example, a System 75 (not System 75 XE) with one Model 1 A control
carrier (use one circuit pack CARRIERS 1 A form), one and up to four port carriers (use three
circuit pack CARRIER xy forms —one for each port carrier). In this example five forms must
be completed. Before any voice terminals, attendant consoles, or trunks can be
administered in the system the correct type of circuit pack must be installed in the

Survey Steps

appropriate slot or, using the Circuit Pack form, a circuit pack must be assigned to the slot.
Use the circuit pack code (circuit pack TN number) when assigning the circuit packs to slots.
The Circuit Pack forms are shown in Figures 4-8 and 4-9. The information entered on the
form can be taken from a completed Port Assignment Record.

Step 4—Required System Forms (Account Team/Client)
The remaining steps in the survey consist of instructions for completing system forms. As
you proceed, there will be times when the data for a field on a form has not yet been
identified. For those cases, note the fields requiring completion and then proceed. Later,
return to the form and complete it as the applicable data is identified.
The following forms are required in all systems and should be completed in the order given.

Step 8—End User Survey (Account Team/Client)
Establish contact with a representative from each department, section, or work group that
will be using the System 75. Each person selected must have the authority to make some
decisions about the new communications system. You will need to interview these contacts
as you go about the process of completing the system forms.
Identify each system user name, terminal type, and extension number to be assigned.
If required, enter each user name, terminal type, and extension number on a floor plan, or
equivalent drawing. The floor plan will help you visualize various work groups and make
later group assignments such as call answering groups or call pickup groups easier. This
drawing, or an equivalent, can then be used by the installation technicians when installing
voice terminals and associated equipment.
For all terminal types and quantities of each type identified, remove the applicable blank
station forms from Chapter 7 and duplicate as many times as necessary.

4-17

CHAPTER 4. COMMUNICATIONS SURVEY

On each duplicated station form, enter the applicable terminal type, user name, extension
number, and port number.

Note:

Refer to Step 2—Port Assignments for information on assigning a port and
obtaining an equivalent port number for entry on the station form.

Step 9—Group Forms (Account Team/Client)
For each of the following features to be provided, review the associated description
contained in Chapter 5 (System Features, Functions, and Services), identify the associated
forms and the fields on the forms to be completed, and determine the number of forms
required. Remove the applicable blank forms from Chapter 7 (Blank Forms) and duplicate as
many times as necessary. Complete each field on the duplicated form as required.

Ž Terminating Extension Groups

Step 10—Voice Terminals/BCTs (Account Team/Client)
Complete the various fields on the previously obtained station forms. Before actually
assigning features on the forms, review the features that can be assigned to each terminal
type, the recommended button nomenclature, and the abbreviated feature name that must be
entered on the form. The maximum number of buttons that can be assigned to a feature or
function must also be considered. Information on each voice terminal type is provided in
Chapter 6 (System Features—Instructions and Forms). The maximum number of buttons
that can be assigned features (administrable buttons) is shown on each terminal type. You
cannot exceed this number when assigning feature buttons to the terminal. Figures show
each terminal that can be assigned, their associated button positions, and a suggested
standard button arrangement.
The recommended button nomenclature is also used in AT&T System 75—Console
Operations, 555-200-700, AT&T System 75—Voice Terminal Operations, 555-200-701, and
related System 75 User Instructions. If different nomenclature is used than that
recommended, the related documentation should be marked to reflect the changes, and the
nomenclature then used in all system assignments. When the terminal is installed, the button
nomenclature is then entered on a label and inserted next to the button that is assigned the
feature. A set of preprinted labels comes with each voice terminal.

4-18

Survey Steps

Step 11—Review (Account Team/Client)
Review all features and services listed in Chapter 5 (System Features, Functions, and
Services) and insure that a form has been completed for all features and services to be
provided. Review all features requiring hardware and insure that a port assignment has been
made on a Port Assignment Record for each circuit pack required, and that the associated
port number has been correctly entered on the associated system and circuit pack
administration forms.
Retain all completed forms for use during system initialization. The method used for
determining circuit pack locations is the same method used at the factory. If there are
differences, the system configuration will be changed to match the Port Assignment Records
before initialization.

•

Abbreviated Dialing 7103A Button Assignment Form—Complete all sections of the
7103A list, if the system uses 7103A Fixed Feature Voice Terminals.

Abbreviated Dialing

• Station Form—Assign lists to voice terminal’s Abbreviated Dialing section. On multiappearance voice terminals, optionally assign buttons to access an Abbreviated
Dialing list entry. For example, if entry 1 on the system list is the number of a branch
office in London, then this entry can be assigned to a button. The call can be placed
by Iifting the receiver and pressing the button. Similarly, entries from a group or
personal list can be assigned to a button. Users can program buttons which are
assigned to an Abbreviated Dialing personal list entry.
Some features have a button directly associated with them; others do not. For
example, a Call Pickup button can be assigned to a multi-appearance voice terminal,
whereas a Priority Calling button cannot. To associate Priority Calling with a button,
assign the Priority Calling feature access code to an Abbreviated Dialing list
(normally, the System List) and then assign that list entry to the button. This is
exactly the same procedure as discussed in the preceding paragraph. The only
difference is that the Abbreviated Dialing list entry is a feature access code instead of
a telephone number.
Certain voice terminals used with System 75 are capable of storing numbers. Like
Abbreviated Dialing, a stored number is automatically dialed when the associated
button is pressed. This, however, is Repertory Dialing, not Abbreviated Dialing. In
this case, the number is stored in the voice terminal, not in the system. Abbreviated
Dialing only applies for numbers stored in the system.
• Console Parameters Form—Assign lists to Console Parameters Abbreviated Dialing
field.
•

Attendant Console—Assign abbreviated dialing list button to attendant console.

•

Abbreviated Dialing System List Form—Establish a System List. Complete all
sections.

• Abbreviated Dialing Group List Form— Establish Group Lists. Contact personnel who
will use Abbreviated Dialing Group List to determine the codes or numbers that
should be entered on the various Group Lists. Blank lists can be established and
codes or numbers can be added later. Also, specify if calls to numbers on this list
should be privileged. Complete all sections.
• Abbreviated Dialing Personal List Form— Establish Personal Lists. Users can
program their own Personal List once the list is in the system via the System Access
Terminal (SAT). Complete all sections.
• Abbreviated Dialing Enhanced List— Establish an Enhanced List. Complete all
sections.
Ž Data Line Data Module—Assign lists to Data Module List 1 section.
Hardware Requirements

AUDIX Interface and Assignments

Audio Information Exchange (AUDIX) Interface and Assignments
Provides a communications link between the System 75 and the Audio Information Exchange
(AUDIX). AUDIX allows both System 75 users and outside callers to write, edit, send, and
forward voice messages to other users. In addition, System 75 users can also receive and
store incoming voice messages from others and transfer calls into AUDIX.
This part provides the instructions and supporting figures required to assign a System 75 V3
and XEV3 to a small, medium, or large AUDIX system. The figures provide a reference to the
forms used to assign the AUDIX interface link and switch assignments. Some of the figures
that show example forms do not show the actual completed form. Some figures only show
that part of the form that can be completed to implement AUDIX features. The figures
(forms) provide examples only. The actual data assigned on the forms depend upon business
requirements and may not be reflected in these examples.
This part also provides the instructions and figures required to implement AUDIX used in a
Distributed Communication System (DCS) or a non-DCS configuration.
The System 75 and AUDIX assignments used in a non-DCS configuration is shown in Figures
5-2 and 5-3. The System 75 and AUDIX assignments used in a DCS configuration is shown
in Figure 5-4. System 75 and AUDIX used in a DCS configuration is considered as the Host
Switch (the switch that has AUDIX connected to it) and the other System 75s are considered
Remote Switches. Figure 5-4 shows three switches with Switch 1 having the AUDIX.
The DCS configuration (Figure 5-4) only references the examples of completed forms used to
assign the two Hunt Groups on the two remote switches (2 and 3) for AUDIX. The figure
also shows the AUDIX data links, Processor and Hop channel assignments, and connections.
This part does not provide the forms, figures, and instructions on how to implement DCS tie
trunks and data links used with AUDIX. The instructions, figures, and examples on how to
implement DCS data links and tie trunks are covered in the DCS section.
The following forms require implementation for AUDIX used in a DCS or non-DCS
configuration:
•

AUDIX Interface to Switch—An AUDIX interface from the System 75 is assigned
using the following implementation forms:
—

Interface Data Module (assigns a physical interface link number for the
AUDIX Link)

—

Interface Links (used to enable the AUDIX Interface Link)

—

Modular Processor Data Module (MPDM) or Modular Trunk Data Module
(MTDM)—The MPDM connects to a large AUDIX system and the MTDM
connects to a small or medium AUDIX system.

—

Hop Channels (DCS configuration only)—Allows the AUDIX channels to hop
from the host switch to a remote switch is a DCS arrangement.

5-21

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

• Call Transfer Into AUDIX—A user who is an AUDIX subscriber or a covering user for
a principal who is an AUDIX subscriber may transfer a call to AUDIX. This requires
use of the Transfer Into AUDIX Feature Access Code or use of an abbreviated dialing
button programmed with this access code.
•

Call Transfer Out of AUDIX—Provides call progress feedback to the calling party in
the form of call ringing and voiced messages if the called party is busy. In addition, a
called party with a display-equipped terminal is informed of the call type (direct or
redirected) and receives associated information about the call.
Note:

•

Recorded Announcements—Provides a recorded announcement for AUDIX users.

•

AUDIX in a Distributed Communications System (DCS)—An AUDIX connected to a
System 75 (host switch) can support other switches (remote switches) in a DCS
network. The remote switch does not have a direct data link connection to AUDIX. It
passes its data to the host switch via processor channels. The AUDIX via DCS has
separately administered hop channels to each of the remote switches in the network.
The host switch then provides the AUDIX connection. All AUDIX features can be
activated from a host or remote switch.

•

AUDIX as an Automatic Call Distribution (ACD) Split—The AUDIX hunt group (must
be host AUDIX hunt group when in a DCS) may be administered as an ACD split by
setting the ACD field on the hunt group to “y”. This allows AUDIX traffic to be
measured via the ACD’s Call Management System (CMS). AUDIX requests for voice
ports are recorded as logins and AUDIX requests to the switch to disable voice ports
are recorded as logouts by the CMS. If an ACD with CMS is not currently configured
in the system, AUDIX traffic measurements may be taken using the System
Measurements feature.

Note:

5-22

Administration for Call Transfer Out of AUDIX must be performed on
the AUDIX machine. AUDIX machine administration is not covered in
this manual. Refer to the appropriate AUDIX manual for additional
information.

See the AUDIX feature description in the AT&T System 75—Feature
Description, 555-200-201, for detailed AUDIX information.

Interface Data Module Form—Complete all fields as required for one physical
channel (interface link). This assigns a physical channel on the switch for the AUDIX
interface. Four interface physical channels (01 to 04) are available for assignment. If
AUDIX is connected to the PIB jack (XEV3), assign physical channel 01 (interface link
1). This number becomes the interface link number on the Interface Links form. The
interface link communicates with the AUDIX port on the AUDIX machine. AUDIX
ports and translations are not part of the System 75 translations but are shown to
give examples on how AUDIX ports are used with the System 75.

•

Interface Links Form—Complete all fields on the form for one link, as required. This
is the physical channel number (01 to 04) assigned on the Interface Data Module
form. If AUDIX is connected to the PIB jack, complete all fields for link 1 (physical
channel 01).

• Processor Channel Assignment Form (non-DCS Configuration)—Complete the
required fields on the form for one AUDIX interface link. Enter the AUDIX link number
from the Interface Links form. Processor Channel 59 must be used for AUDIX.

5-23

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

• Processor Channel Assignment Form (DCS Configuration)—
— Host Switch—Assign the link numbers and associated channels to each
remote switch.
— Remote Switch—Enter the interface links number and associated information
including the host switch machine ID for the DCS AUDIX connection.
• Modular Processor Data Module (MPDM) or Modular Processor Trunk Data Module
Form—Complete all fields as required. Complete an MTDM form for a large AUDIX
system or an MPDM form for a small or medium AUDIX system. The MPDM or
MTDM connects to a TN754 Digital Line circuit pack.
Note:

Instead of administering an MPDM or MTDM form, the AUDIX data
link may be directly connected to the Processor Interface Board (PIB)
jack (XEV3 only) on the back of the Control Carrier (if not already
assigned). The PIB jack interface utilizes Interface Link 1 which is
administered using the Interface Data Module and Interface Links
forms.

• Hop Channel Assignments Form—Complete as required to assign hop channels so
the host System 75 switch interface link can have a hop channel to the remote
switches.
Figure 5-4 shows an AUDIX In A DCS Network arrangement consisting of three System 75
switches. Associated Hop Channel and Processor Channel Assignments forms for each
switch is provided in addition to related AUDIX translations. The AUDIX translations are not
part of the System 75 translations but are presented here for a better understanding of the
system. Figure 5-4 does not cover any translations for DCS.
Translation assignments on AUDIX and each switch must be coordinated to insure proper
operation. It is recommended that Interface Channel numbers associated with each logical
link match AUDIX port numbers on all forms. This helps in coordinating assignments and
aids in troubleshooting.
The following guidelines must be observed when making AUDIX assignments on the System
75:
Processor Channel Assignment Form
1.

The entry in the Remote Processor Channel field (on System 75) must agree with
associated AUDIX port fields (on AUDIX).
For example, as shown on Figure 5-4, the association of each System 75 switch
to an AUDIX port is shown on the AUDIX Translations form where Switches 1, 2,
and 3 are associated with AUDIX ports 1, 2, and 3, respectively. Also note that
the interface to each switches processor is via Switch Port (that is, Processor
Channel) 59. As a result of this association, the Remote Processor Channel
entries on switches 1, 2, and 3 Processor Channel Assignments forms for
Processor Channel 59, as shown, are 1, 2, and 3, respectively.

5-24

AUDIX Interface and Assignments

2. Machine IDs entered on the form (on System 75) must agree with the AUDIX field
entry on the AUDIX Data Link form (on AUDIX—form not shown). Typically, with just
one AUDIX, this entry is “1”.
Hop Channel Assignments Form
Interface Link Channel entries (on System 75) used to show the host switch interface to
AUDIX must agree with related AUDIX logical channels (on AUDIX).
For example, as shown on Figure 5-4, Interface Link 1, Channel 2 (1 ,2) is shown logically
connected to AUDIX logical channel 2. This then becomes part of the first line entry on
the Hop Channel Assignments form as shown. A similar situation is shown for Interface
Link 1, Channel 3 (1 ,3) which is entered on the second line of the form. The remaining
entries on the Hop Channel Assignments form complete the hop connection to Switch
#2 and Switch #3. The Interface Link assigned to AUDIX (Interface Link 1 in the
example) is a dedicated link and cannot be assigned to another interface such as a link
to another DCS switch, Applications Processor, Call Management System, or Property
Management System.

Hop Channel Assignments and Processor Channel Assignment Forms
Interface Link Channel assignments (on System 75) between switches must agree,
For example, as shown on Figure 5-4, Interface Channel 2 is shown associated with the
logical link from Switch #1 to Switch #3. Channel 2 is then entered on Switch #10’s
Hop Channel Assignments form and on Switch #9’s Processor Channel Assignments
form. A similar situation is shown for Interface Channel 3 to Switch #3.

• Authorization Codes Form—Assign 4- to 7-digit authorization codes (with CORs for
0-63).
— Number of Codes Administered field—Display-only field. Contains sum of
total codes administered.
— In the AC field, enter the 4- to 7-digit authorization code the user must dial.
The number of digits entered must agree with the number assigned to the
Authorization Code Length field on the Feature Related System Parameters
form.

5-43

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

— In the Class of Restriction field, enter the desired COR number from 0
through 63. This is the replacement COR to be used to modify the user’s
calling privileges and is effective after the corresponding authorization code
has been dialed.
•

Feature Related System Parameters Form—Verify “y” (yes) is entered in the
Authorization Code Enabled field so that Authorization Codes can be assigned on a
systemwide basis.
— In the Authorization Code Length field, enter a number from 4 to 7 that
defines the number of digits (length) in the authorization code. This is the
number of digits that must be assigned to the authorization code (AC) field on
the Authorization Codes form.
— In the Authorization Code Cancellation Symbol field, enter the type of symbol
the caller must enter to cancel the 10-second delay before entering the
authorization code.
— In the Attendant Time Out Flag field, define if the caller will be routed to the
attendant if the caller does not dial an authorization code within 10 seconds
or dials an invalid authorization code.

•

Station Forms—Assign CORs arbitrarily so a separate COR exists for users with
different restrictions. If CORs are already established, they must be taken into
account when adding/assigning new CORs.

• Class of Restriction Form—in FRL field, assign originating Facility Restriction Levels
for restricted and unrestricted users. The originating FRL can be a value of 0
through 7 where 0 is the most restrictive.
•

Routing Patterns Form—
— In the Group Number field, enter the desired trunk group number 1 through
99.
—

In the FRL field, assign route FRLs for each trunk group in the Route Pattern.
A route FRL of 7 is the most restrictive and a route FRL of 0 is the least
restrictive. (Note that trunk groups must have been assigned previously on
the Trunk Group form.) The first choice trunk group has the lowest FRL, the
second choice trunk group (if there is one) has the next lowest FRL, etc. The
assigned FRL will be used for this pattern only. Trunk group FRLs are
changeable from pattern to pattern. The FRL assigned to the trunk group
when the COR is defined is not used on ARS calls.
The route patterns in use on the network and the associated trunk group
FRLs must be a consideration when implementing authorization codes.

• Remote Access
— In the Authorization Code Required field, enter “y” if an Authorization Code
must be dialed to access the System 75 features remotely; otherwise, enter
“n. ”

Authorization Codes

— In the Remote Access Dial Tone field, enter “y” if the user will receive a
recall dial tone before dialing the authorization code. If Barrier Codes are
assigned, the recall dial tone is heard after the Barrier Code has been dialed.
• Trunk Group Forms— In the Authorization Code field, enter a “y” if an Authorization
Codes must be dialed to access the trunks in a trunk group; otherwise, enter “n.”
The following three examples tell how to assign Authorization Codes.
Example 1.
Establish a group of users who must dial an authorization code in order to make outside
calls. The client has ARS and the Authorization Codes feature. The forms and fields are
administered as follows:
1.

2. Station Form
Assign COR = 1 for all unrestricted users and COR = 49 for restricted users who
must dial an authorization code to make outside calls.
3. Authorization-Codes Form
Assign the restricted users a replacement COR = 1 and an authorization code the
same as their 7-digit phone number.
4. COR Form
Assign/change originating FRLS for restricted and unrestricted users. Assign an
originating FRL of 7 to users with a COR of 1 and an originating FRL of 0 (zero) to
users with a COR of 49.
5. AAR/ARS Route Pattern Form
For route pattern 1, assign trunk group 40 (CO) as the first choice route with a route
FRL = 1, NPA = 201, and Prefix Mark = 1 (that is, dialing “1” is required here to
indicate a toll call). Assign first, second, and third choice routes as follows:

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

For thIs example, trunk group 40 is a CO trunk, trunk group 2 is WATS, and trunk group 32
is a tie trunk to the System 85.
When a caller dials the ARS access code to call out, the FRL of the originating facility is
compared with the FRL of the available outgoing facility. If the FRL of the originating facility
is less than the FRL of the trunk group, the restricted user will be prompted (via recall dial
tone) to enter an authorization code. After the authorization code is entered, the call is
routed to the CO for completion. If the FRL is insufficient to seize any trunk group in the
route pattern, the user gets intercept tone.
Restricted callers will be prompted for and be required to enter an authorization code (as
previously described). Unrestricted users will simply dial the ARS code followed by the
desired number.
Refer to AT&T System 75 Feature Description, 555-200-201, for additional information on the
use of AAR/ARS FRLs for control of call routing.
Example 2.
Set up remote access to the switch such that the remote user must enter a barrier code and
an authorization code to access the System 75 features from home.

• Remote Access using the DID Feature
To use remote access through the DID feature, dial the 7- to 10-digit Remote Access
number (957-XXXX) followed by the barrier code (4444). After you hear recall dial
tone, enter the authorization code, for example, the 7-digit station extension number
(957-ZZZZ), followed by the desired number, or dial the ARS access code (9) and the
7- or 10-digit number you are calling. The call will be routed through to completion.
• Remote Access using a dedicated CO, FX, or WATS Trunk
To implement the remote access feature via a dedicated CO, FX, or WATS trunk, the
Remote Access form is administered as above. In addition, the Incoming Destination
field is assigned the Remote Access Extension number on the Trunk Group form.

5-46

Authorization Codes

When the caller dials the Listed Directory Number associated with the trunk group
dedicated to Remote Access, the trunk group routes the call to the Remote Access
Extension. The caller will hear a data tone followed by dial tone. The barrier code is
then entered and, in this example, since Remote Access Dial Tone is set to “1”, the
caller will be prompted (via recall dial tone) to enter an authorization code. After the
authorization code is entered, the caller will hear system dial tone. At this point, the
desired number can be dialed and routed to completion.
Example 3.
On a system that does not use AAR or ARS for call routing, implement the Authorization
Codes feature to allow a caller to override the originating COR assigned to a specific CO
trunk group. On the trunk group form, enter “y” in the Authorization Code field if an
authorization code must be dialed to access the trunks in the specified trunk group. This is
in addition to administering the parameters on the System Parameters Features form, the
Station form, the Authorization Codes form, and the COR form as specified in Example 1.
Hardware Requirements
None.

Automatic Alternate Routing

Guidelines and Examples
The examples given here are designed to help in the understanding of AAR and to illustrate
some of the practical aspects of AAR. These are, however, only examples. In reality, each
system must be administered to meet its individual needs.

Completing the Class of Restriction Form
Make assignments as required for the following field:
•

FRL—Assign a Facility Restriction Level (0 through 7) for each voice terminal user
activating AAR. An FRL of 0 (zero) is the most restrictive and an FRL of 7 is the
least restrictive. The FRL of the calling facility is compared against the FRL of the
AAR pattern choices to select an allowed route.

Completing the Feature Access Codes Form
Make assignments as required for the following field:
•

Auto Alternate Routing (AAR) Access Code—Assign an access code to AAR. The
usual entry is “8.”

Completing the Routing Pattern Form
Make assignments as required for the following fields:
•

Pattern Number—Enter a Pattern Number 1 through 254.

•

Grp No.—Enter the desired trunk group number 1 through 99.

•

FRL—Enter the Facility Restriction Level 0 through 7 (“0” being the least restrictive
and “7” being the most restrictive) for this trunk group as it will be used by this
pattern only. Trunk group FRLs are changeable from pattern to pattern. The FRL
assigned to the trunk group when the Class of Restriction (COR) is defined is not
used on AAR calls. The NPA, Prefix Mark, and Toll Table fields listed below are used
by ARS and not AAR.

•

NPA—Enter the NPA of the distant end.

•

Prefix Mark—Enter a number 0 through 3 as indicated. This determines the
outpulsing of the Prefix digit 1.
— 0— indicates that the Prefix digit 1 is never outpulsed.
— 1— indicates that the Prefix digit 1 is outpulsed if and only if the call is a 10digit call. Prefix Mark 1 should be selected for those HNPAs that require
users to dial “1” to indicate a toll call.

5-49

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

— 2— indicates that the Prefix digit 1 is outpulsed for all toll calls, 7- and 10digit, whether the user dials it or not.
— 3— indicates that the Prefix digit 1 is outpulsed for all toll calls. Toll calls are
always outpulsed as 10-digit numbers, even those within the HNPA.
Note:

Prefix Marks 2 and 3 must refer to a Toll Table (see next entry).

• Toll List—Enter a number, 1 through 32, that references the ARS Toll Table assigned
to this trunk group. This field must be completed if the Prefix Mark is 2 or 3.
•

No. Del. Digits— Enter the total number of digits (0 through 11) to be deleted from the
dialed number when this trunk group is selected for use within this pattern.

•

Inserted Digits—Enter the actual digits to be inserted, 0 through 36. The digits may
be divided into groups separated by a wait (˜w) for dial tone separator. “Wait” takes
two digit places.

Completing the RNX Translation Table
For each of the 640 RNXs available, enter “h” or “H” for a Home RNX or a pattern number
(1 through 254). More than one “h” and/or “H” may be assigned.
The default value for all 640 RNX codes is 254 (Routing Pattern 254). The pattern used most
often in RNX Translation should be assigned to this pattern number to minimize the number
of changes required to complete this form.

Hardware Requirements
None.

Automatic Call Distribution

Automatic Call Distribution
Provides automatic connection of incoming calls to specific splits (hunt groups). Calls to a
specific split are automatically distributed among the agents (hunt group members) assigned
to that split. Automatic Call Distribution (ACD) data, transmitted from the switch to the Call
Management System (CMS), is used to generate various reports on the status of ACD
agents, splits, and trunks.
ACD is implemented using the features or functions listed below. These features can be
used singularly or in combination with each other. The features are listed alphabetically

Hardware and Software Requirements
Each auxiliary queue warning level lamp requires one port on a TN742, TN746, or TN769
Analog Line circuit pack. A 21C-49 indicator lamp may be used as a queue warning level
lamp. This lamp is approximately 2 inches in diameter and has a clear beehive lens. The
lamp operates on ringing voltage and can be mounted at a location convenient to the split.
Each delay announcement requires one port on a TN750 Integrated Announcement circuit
pack or announcement equipment and one port on a TN742, TN746, or TN769 Analog Line
circuit pack. The four analog announcements should be assigned on the TN742 ports since
the TN742 can only ring four ports at a time. If music is to be heard after the first delay
announcement, a music source and a port on a TN763 Auxiliary Trunk circuit pack is
required. Music sources are not provided by the system.
ACD software is required. If a CMS is to be used, CMS software is required.
A typical ACD arrangement is shown in Figure 5-22.

Guidelines and Examples
The examples given here are designed to help understand ARS and to illustrate some of the
practical aspects of ARS. These are, however, only examples. In reality, each system must
be administered to meet its individual needs.

Completing the Dial Plan Record
Make assignments as required for the following fields:
• Area Code—Enter the Home Numbering Plan Area of the PBX.
• ARS Prefix 1 Required—Enter “y” if the user is required to dial 1 to indicate a 10digit toll call. This is required when the PBX is located within an area code that
contains a central office code resembling an area code. These are the following:
— 201 in New Jersey
— 212 in New York
— 213 in Los Angeles
— 312 in Chicago
— 706 in Northwest Mexico
— 905 in Mexico City
The following paragraphs show how dialed numbers are interpreted by the system if
y is assigned to “ARS Prefix 1 Required. ” The number 9 represents the ARS
Access Code.
1.

9+1+(212)-201-1234 infers a 10-digit toll call.

2. 9+(212)-201-1234 infers that 212 is a Central Office Code. The system
accepts only the first seven digits following the ARS Access Code. The
number 212-2011 is sent to the Central Office.
3. 9+201-1234 infers a 7-digit call within the HNPA.

5-58

Automatic Route Selection

4. 9+1+201-1234 infers the first seven digits of a 10-digit toll call and waits for
the remaining three digits. The number being outpulsed is (201)-123-4xxx.
If the number being dialed is a toil call within the HNPA and the Central Office
Code resembles an area code as in the example above, then the HNPA must
also be included in the number dialed (refer to example number 1).
5. 9+922-1234 or 9+1+922-1234 infers a 7-digit call (or toll call) within the
HNPA. This example differs from example number 4 in that the Central
Office Code (922) does not resemble an area code.
•

FIRST DIGIT TABLE—Assign “fac” as the Identification for the Digit 9.

Completing the Feature Access Codes Form
Make assignments as required for the following fields:
Ž

Auto Route Selection (ARS) Access Code—Assign an access code to ARS. The
usual entry is “9.”

Completing the ARS Routing Patterns Form
Make assignments as required for the following fields:
• Pattern Number—Enter a Pattern Number 1 through 254.
• Grp No.— Enter the desired trunk group number 1 through 99.
• FRL—Enter the Facility Restriction Level 0 through 7 (’‘0” being the least restrictive
and “7” being the most restrictive) for this trunk group as it will be used by this
pattern only. Trunk group FRLs are changeable from pattern to pattern. The FRL
assigned to the trunk group when the Class of Restriction (COR) is defined is not
used on ARS calls.
• NPA—Enter the NPA of the distant end. For WATS trunk, the term NPA is the same
as the home NPA. For Tie trunks, the NPA field is left blank.
• Prefix Mark—Enter a number 0 through 3 as indicated. This determines the
outpulsing of the Prefix digit 1.
— 0— indicates that the Prefix digit 1 is never outpulsed.
— l— indicates that the Prefix digit 1 is outpulsed if and on/y if the call is a 10digit call. Prefix Mark 1 should be selected for those HNPAs that require
users to dial “1” to indicate a toll call.
— 2— indicates that the Prefix digit 1 is outpulsed for all toll calls, 7- and 10digit.

5-59

CHAPTERS. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

— 3— indicates that the Prefix digit 1 is outpulsed for all toll calls. These calls
are always outpulsed as 10-digit numbers, even those within the HNPA.
Note:

Prefix Marks 2 and 3 must refer to a Toll Table (see next entry).

• Toll List—Enter a number, 1 through 32, that references the ARS Toll Table assigned
to this trunk group. This field must be completed if the Prefix Mark is 2 or 3.
• No. Del. Digits—Enter the total number of digits (0 through 11) to be deleted when
this trunk group is selected for use within this pattern.
•

Inserted Digits— Enter the actual digits to be inserted, O through 36. The digits may
be divided into groups separated by a wait for dial tone separator. “Wait” takes two
digit places. The “,” is used for pause, “+” for the second dial tone, and “%” for
end-to-end signaling.

As an example, assume that an FX Group to North Carolina (Area Code 919) is being
defined:
1.

The ARS user dials 9+(91 9)-555-1349. (The first “9” represents the ARS Access
Code.)

The System checks the ARS FNPA Table for the assigned Routing Pattern. The FX
Trunk Group is the first choice in the Pattern assigned to Area Code 919.

If a trunk is available on this group, then the call is allowed. If a trunk is not
available, then the system will search for an available trunk on the next trunk group
listed for this NPA.

The System defines the trunk group assigned to this route. Assume that the value
assigned to “No. Del. Digits” is 3. The system deletes the first three digits, left to
right. The digits 919 are deleted.
Prefix Mark 2 is specified, Toll Table 3 is checked to determine if the call is local or
toll with respect to the office at the distant end of the trunk. If local, the number
555-1349 is outpulsed; if toll, 1-555-1349 is outpulsed.
No digits are inserted for this example.

Completing the Home Numbering Plan Area Table
This 800-entry table consists of eight screen forms of 100 office codes each: 200-299,300399,...800-899, 900-999. These screen forms define the patterns to be used to complete toll
and local calls within the HNPA.
The default entry for all 800 office codes is Pattern 1. Normally, Pattern 1 should be used as
the HNPA to// pattern, because in most NPAs there are more toll office codes than there are
local office codes. This will minimize the number of changes required to complete the form.

Completing the Foreign Numbering Plan Area Table
This 200-entry table consists of two screen forms of 100 area codes each. These area
codes must be directed to a pattern or another table. The default pattern for these entries is
intercept-pattern 0, although that specific entry will not be displayed.
The system recognizes certain types of dialing patterns on outgoing calls and routes these
calls via special entries in the HNPA or FNPA table. Table 5-A lists the special dialing
patterns along with the associated HNPA or FNPA table entry through which that type of call
is routed.

Completing the Remote Home Numbering Plan Area
This 800-entry table consists of eight screen forms of 100 office codes each: 200-299, 300399,...800-899, 900-999. Up to 32 RHNPA Tables may be completed. Each screen form
provides fields for the selection of up to 12 Routing Pattern choices. Each Office Code is
assigned a Routing Pattern from the 12 choices assigned to that screen. Each screen may
have 12 different choices. It is not necessary to assign all 12 choices.

5-62

Automatic Route Selection

RHNPA Tables can be used to define the office codes of an FX trunk group whose area
code differs from the HNPA as well as any area code in which it is desired to grant/deny
access to specific office codes.
Enter a number (1 through 12) for each Office Code to reference the desired Pattern choice.
Ranking of Pattern choices is not pertinent; however, because the default value for each
Office Code is 1, the Routing Pattern assigned to Pattern Choice 1 should be the one used
most frequently.

Completing the Toll Table Form
This 800-entry table consists of eight screen forms of 100 office codes each: 200-299, 300399,...800-899, 900-999. Up to 32 ARS Toll Tables may be completed. The default value for
each office code is “y.” This implies that all calls are toll calls. To identify those calls within
the Table that are not toll calls, change the y to n beside the appropriate office codes.
Toll Tables are associated with the terminating NPA of a given trunk group. They are always
required for those trunk groups given a Prefix Mark of 2 or 3 on the Routing Pattern form.
Toll Tables may be shared by any number of trunk groups having the same NPA.
Whenever the system needs to know if a call is toll, a toll table must be created.

Hardware Requirements

Call Coverage

Guidelines and Examples
The examples given here are designed to help understand Call Coverage and to illustrate
some of the practical aspects of Call Coverage. These are, however, only examples. In
reality, each system must be administered to meet its individual needs.
Three typical coverage arrangements are as follows:
• Executive Coverage
Provides a principal with call redirection to covering users having a close working
relationship with the principal. Because of the status of the principal, personalized
answering should be provided. Also, the principal may or may not choose to answer
his or her own calls.
A typical example of this form of coverage is when a principal’s calls are redirected
to a secretary. The secretary would be informed of the principal’s daily schedule and
other pertinent facts such as the importance of certain calls. The secretary could
provide personalized answering by answering calls with the principal’s name.
If the secretary is unavailable to answer the coverage call for the principal, the call
redirects to a backup answering position. Personalized answering should also be
provided at the backup position.
• Middle Manager Coverage
Provides a group of principals with call redirection to one or more covering users
(such as a secretary). The secretary should have some knowledge of the principal’s
daily schedule. A backup answering position should be provided in case the
secretary is unavailable.
• General User Coverage
Provides less-personal coverage for a broader spectrum of users. Covering users
typically consist of a group or pooled answering arrangement. With this type of
arrangement, coverage calls may be distributed among the members of the
answering group.
As an example of how to provide a particular cover arrangement, the following provisions for
the Executive Coverage arrangement are given.
• 83Determine if the secretary and backup position have a call display capability.
— If so, Coverage Answer Groups are not required.
— If not, establish a unique Coverage Answer Group for each one without a
display. Specify only the applicable extension number. The Coverage
Answer Group will contain only one member. Establish two groups, if
required. Note that if the secretary and/or the backup answering position are
in a Coverage Answer Group, each will receive only one redirected call for
the executive at any given time. Calls do not ring a Coverage Answer Group
member already busy on a call to the group. For frequently called

5-71

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

executives, it is desirable that the secretary and possibly the backup
answering position have a digital display capability.
• Establish a unique Call Coverage Path for the executive,
— If the secretary will screen the calls, specify Cover All Calls as the redirection
criteria.
— If the executive will answer calls, specify Active, Busy, Don’t Answer,
Active/Don’t Answer, or Busy/Don’t Answer as desired.
— Specify the secretary and the backup position [or the Coverage Answer
Group(s) containing the secretary’s and backup position’s extension
numbers] as the coverage points in the path.
•

Optionally, specify a Send All Calls button on the executive’s voice terminal. If
someone else answers the executive’s calls, the button is not needed.

•

Specify a Send All Calls button and a Consult button on the secretary’s voice
terminal. Specify a Coverage ICI button if the secretary doesn’t have a call display
capability. Send All Calls is needed if the secretary will be unavailable for a period of
time. Consult is needed to enable private consultation with the executive during an
established call. Coverage ICI is needed to identify the call as a call to the executive
rather than a personal call to the secretary.

• Specify a Consult button and a Coverage ICI button on the backup position’s voice
terminal for the same reasons these buttons were specified for the secretary.

Centralized Attendant Service
Allows services performed by attendants in a private network of switching systems to be
concentrated at a central, or main, location. Each branch in a Centralized Attendant Service
(CAS) has its own listed directory number (LDN) or other type of access from the public
network. Incoming trunk calls to the branch, as well as attendant-seeking voice terminal
calls, are routed to the centralized attendants over release link trunks (RLTs).
Optional CAS software is required before this feature can be activated.

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

Class of Restriction
All system users have a COR to define their calling privileges. Restrictions can be assigned
to a facility as listed in the table below. The COR specifies up to 64 different classes of call
origination and termination privileges. Systems may have only a single COR, one with no
restrictions, or may have as many CORs (up to 64) as necessary to effect the desired
restrictions. A unique COR must be defined for each combination of FRLs, calling party
restrictions, called party restrictions, miscellaneous restrictions, and CCSA/EPSCS offnetwork restrictions.

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

Guidelines and Examples
The examples given here are designed to help understand CORs and to illustrate some of
the practical aspects of CORs. These are, however, only examples. In reality, each system
must be administered to meet its individual needs.

Example Using Miscellaneous Restrictions
As an illustration of miscellaneous restrictions, assume a System 75 installation provides the
following:
• Central office trunks
• WATS
• FX trunks
• Data modules
Ž Attendant service
• Voice terminals
• Direct Inward Dialing (DID) trunks
• Remote Access
In an unrestricted environment, each of the preceding facilities could have the same COR.
However, suppose the following requirements exist:
• Attendants cannot make data calls.
• Remote Access can be used for data calls only.
• DID cannot be used for data calls except through Remote Access. (A dedicated
Remote Access trunk group is not required, although one or more could be provided.
This example assumes all Remote Access is via DID.)
• There are three classes of voice terminals:
— Those that can call anywhere, any time
— Those that can place local central office and in-house calls only
—

Those that can place local central office, FX, and in-house calls only

To implement the preceding requirements, a COR must be assigned to each facility or group
of facilities. For simplicity, each can have a unique COR. The CORs are arbitrarily assigned
as follows:

5-88

Class of Restriction

Ž COR 30—Local central office trunks
Ž COR 31—WATS trunks
Ž COR 32—FX trunks
• COR 33—Data modules
Ž COR 34—Attendant group
• COR 35—Unrestricted voice terminals
• COR 36—Voice terminals that can place in-house and local central office calls only
(no FX or WATS calls)
• COR 37—Voice terminals that can place in-house, local central office, and FX calls
only (no WATS calls)
• COR 38—DID trunk group
• COR 39—One of the remote access barrier codes (can be up to ten)
With the CORs defined, it should be individually determined which CORs cannot call other
CORs. This is done as follows:
• COR 30 (local central office trunks)—No restrictions were specified for these trunks.
The default values on the screen form are sufficient. No action is required, except to
specify a COR number of 30.
• COR 31 (WATS)—CORS that cannot use WATS are specified as they are
encountered. WATS itself is an outgoing service without any calling capabilities.
Thus, Miscellaneous Restrictions are not specified on this form. The Calling Party
Restriction should be “none” (although this restriction does not really have any
meaning for an outgoing facility). Similarly, the Called Party Restriction applies to
facilities capable of answering a call. Since this is not the case with WATS, “none”
should be specified. Again, the default values are sufficient, so only the COR number
needs to be specified.
• COR 32 (FX)—According to the requirements for this example, no restrictions apply.
Reasons are the same as for WATS. Only the COR number needs to be specified.
• COR 33 (data modules)—No restrictions apply for reasons similar to the reasons why
no restrictions were assigned for WATS. Only the COR number needs to be
specified.
• COR 34 (attendant group)—The attendant group cannot call COR 33 (data modules).
Specify an “n” beside COR 33 in the Calling Permission field. Specify 34 in the COR
Number field.
• COR 35 (unrestricted voice terminals)—Since no restrictions were specified, only the
COR number needs to be entered.

5-89

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

•

COR 36 (no FX or WATS calls)—This COR cannot call COR 32 (FX) or COR 31
(WATS). Specify an “n” beside CORs 32 and 31 in the Calling Permission field.
Specify 36 in the COR Number field.

• COR 37 (no WATS calls)—This COR cannot call COR 31 (WATS). Specify an “n”
beside COR 31 in the Calling Permission field. Specify 37 in the COR Number field.
• COR 38 (DID)—This COR cannot call COR 33 (data modules). Specify “n” beside
COR 33 in the Calling Permission field. Enter 38 in the COR Number field.
• COR 39 (Remote Access barrier code)—This COR can be used for data calls only.
Thus, this COR can call COR 33, but not CORs 30 (local central office), 31 (WATS),
32 (FX), 34 (attendant group), 35, 36, or 37 (voice terminals). Specify an “n” beside
CORs 30, 31, 32, 34, 35, 36, and 37 in the Calling Permission field. Enter 39 in the
COR Number field. (The CORs listed in the Calling Permission field can be viewed as
terminating or screening CORs that can or cannot be called by the originating COR.
Since COR 38 [DID] is neither a terminating nor a screening COR, it does not have to
be considered when assigning the barrier code COR.)

Example Using Calling Party Restrictions, Called Party Restrictions, and Miscellaneous
Restrictions
To illustrate the use of both Calling and Called Party restrictions, and Miscellaneous
restrictions, assume a System 75 installation provides the following:
Ž Central office trunks (outgoing)
• WATS
Ž FX trunks (outgoing)
• Voice terminals
Ž Data modules
• Terminating Extension Groups
• Loudspeaker Paging
Suppose that the following requirements exist:
Ž Only the attendant can access loudspeaker paging.
Ž Terminating Extension Groups can only accept calls from internal voice terminals.
• There are six classes of voice terminals:
— Those that are toll restricted

5-90

Class of Restriction

— Those that cannot call outside to a public network (outward restricted)
— Those that can receive calls only from an attendant
— Those that can call anywhere, any time
— Those that cannot place FX or WATS calls
— Those that cannot place WATS calls
To implement the preceding requirements, a COR must be assigned to each facility or group
of facilities. For simplicity, each can have a unique COR. The CORs are arbitrarily assigned
as follows:
• COR 40—Local central office trunks
• COR 41 —WATS trunks
Ž COR 42—FX trunks
Ž COR 43—Attendant group
• COR 44—Data modules
• COR 45—Terminating Extension Groups
• COR 46—Loudspeaker Paging Access Zones
Ž COR 47—Unrestricted voice terminals
• COR 48—Voice terminals that are toll restricted
Ž COR 49—Voice terminals that are outward restricted
Ž COR 50—Voice terminals that can only receive calls from an attendant
• COR 51 —Voice terminals that cannot place FX or WATS calls
• COR 52—Voice terminals that cannot place WATS calls
With the CORs defined, it should be determined individually which CORs cannot call other
CORs. This is done as follows:
Ž COR 40 (local central office trunks)—Restrictions that prohibit access to this COR
are assigned when the originating CORs are considered. Only the COR number has
to be specified on this form.
• COR 41 (WATS)—Only the COR number needs to be specified, this is the same case
as described in the previous configuration example,
• COR 42 (FX)—Again, only the COR number needs to be specified.

5-91

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

Ž COR 43 (attendant group)—No restrictions were stated, so only the COR number
needs to be specified.
• COR 44 (data modules)—No restrictions were stated, so only the COR number needs
to be specified.
• COR 45 (Terminating Extension Group)—This COR can receive internal voice
terminal-originated calls only. Since no tie trunks are specified for this example, the
Inward Restriction feature can provide the desired restriction. Specify “inward” as
the Called Party Restriction. If dial repeating tie trunks are provided, Miscellaneous
Restrictions could be used to deny trunk access to the group. Also, specify 45 as
the COR number.
Ž COR 46 (Loudspeaker Paging Access zones)—Since this COR can be accessed by
an attendant only, the Manual Terminating Line feature can provide the restriction.
Specify “manual” as the Called Party Restriction. Specify 46 as the COR number.
Ž COR 47 (unrestricted voice terminals)—No restrictions were stated, so only the COR
number needs to be specified.
• COR 48 (toll restricted voice terminals)—Specify “toll” as the Calling Party
Restriction. Specify 48 as the COR number.
• COR 49 (outward restricted voice terminals)—Specify “outward” as the Calling Party
Restriction. Specify 49 as the COR number.
Ž COR 50 (voice terminals that can only receive calls from an attendant)-Specify
“manual” as the Called Party Restriction. Specify 50 as the COR number.
• COR 51 (voice terminals that cannot place WATS or FX calls)—None of the Calling
Party Restrictions uniquely prohibit WATS and FX calls, so Miscellaneous
Restrictions are used. Enter an “n” beside COR 41 (WATS) and COR 42 (FX) in the
Calling Permission field. Leave the Calling Party Restriction as “none” and specify
51 as the COR number.
• COR 52 (voice terminals that cannot place WATS calls)—Enter an “n” beside COR
41 (WATS) in the Calling Permission field. Leave the Calling Party Restriction as
“none” and specify 52 as the COR number.
Another method to determine COR assignment is to consider the restrictions to be assigned.
This method is probably more difficult to use, but it minimizes the number of CORs
established. This method requires 9 CORs to effect the same restrictions as 13 CORs with
the previous method.
The requirements given for this example are as follows:
• Only the attendant can access loudspeaker paging.
• Terminating Extension Groups can only accept calls from internal voice terminals.

5-92

Class of Restriction

• The six classes of voice terminals are:
— Those that are toll restricted
— Those that cannot call outside to a public network (outward restricted)
— Those that can receive calls only from an attendant
— Those that can call anywhere, any time
— Those that cannot place FX or WATS calls
— Those that cannot place WATS calls
Assignments for these requirements could be made as follows:
• COR 20—Manual Terminating Line Restriction.
• COR 21 —Inward Restriction,
Ž COR 22—Toll Restriction.
• COR 23—Outward Restriction.
Note:

A new Manual Terminating Line Restriction for voice terminals was
not established. COR 20, above, can be assigned.

• COR 24—Unrestricted.
• COR 25—COR for WATS.
• COR 26—COR for FX.
• COR 27—Provides Miscellaneous Restrictions for WATS and FX. Enter an “n”
beside COR 25 and COR 26 on the form for COR 27.
• COR 28—Provides Miscellaneous Restriction for WATS. Enter an “n” beside COR
25 on the form for COR 28.
Now assign the appropriate COR to each physical or screening facility:
Ž Central office trunks—COR 24 (unrestricted)
• WATS—COR 25 (WATS COR)
Ž FX—COR 26 (FX COR)
• Attendant group—COR 24 (unrestricted)
• Voice terminals—COR 22 (toll), COR 23 (outward), COR 20 (manual), COR 24
(unrestricted), COR 27 (WATS and FX miscellaneous), or COR 28 (WATS
miscellaneous), as required

5-93

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

Authorization-Codes Form
Assign the restricted users a replacement COR = 1 and an authorization code the
same as their 7-digit phone number.

COR Form
Assign/change originating FRLS for restricted and unrestricted users. Assign an
originating FRL of 7 to users with a COR of 1 and an originating FRL of 0 (zero) to
users with a COR of 49.

AAR/ARS Route Pattern Form
For route pattern 1, assign trunk group 40 (CO) as the first choice route with a route
FRL = 1, NPA = 201, and Prefix Mark = 1 (that is, dialing “1” is required here to
indicate a toll call). Assign first, second, and third choice routes as follows:

For this example, trunk group 40 is a CO trunk, trunk group 2 is WATS, and trunk group 32
is a tie trunk to the System 85.

5-94

Class of Restriction

When a caller dials the ARS access code to call out, the FRL of the originating facility is
compared with the FRL of the available outgoing facility. If the FRL of the originating facility
is less than the FRL of the trunk group, the restricted user will be prompted (via recall dial
tone) to enter an authorization code. After the authorization code is entered, the call is
routed to the CO for completion. If the FRL is insufficient to seize any trunk group in the
route pattern, the user gets intercept tone.
Restricted callers will be prompted for and be required to enter an authorization code (as
previously described). Unrestricted users will simply dial the ARS code followed by the
desired number.
Hardware Requirements
None.

Data Call Setup is a means of using data equipment to establish data calls. Requirements
for data modules, 510D or 515 BCT voice terminals, and modems are given below.

5-102

Data Call Setup

• Data Modules: Each data module requires one port on a TN754 Digital Line circuit
pack. A Digital Terminal Data Module (DTDM) shares the port with its associated
voice terminal.
Ž 510D or 515 BCT: Each 510D or 515 BCT requires one port on a TN754 Digital Line
circuit pack for shared use of voice and data.
• 7404D, 74060, or 7407D: Each Voice Terminal requires one port on a TN754 Digital
Line circuit pack for shared use of voice and data.
Ž Modems: Each modem requires one port on a TN742 Analog Line circuit pack.
(Administration designates the modem as a 2500-series voice terminal and assigns
an extension number. A modem is connected to the port instead of a voice terminal.
Access is through the assigned extension number.)
• Modern Pooling: A TN758 Modem Pool circuit pack, or one digital port associated
with a Trunk Data Module (either TDM or MTDM) and one analog port with analog
modem, is required for each conversion resource.
•

Keyboard Dialing to off-premises data endpoints requires the use of a TN748B Tone
Detector circuit pack. Extensive use of features and services using tone detection
may necessitate adding additional TN748B circuit packs (several features also use a
TN748B).

Distributed Communications System

Distributed Communications System (DCS)
Allows a configuration (cluster) of two or more switches (nodes) to provide certain attendant
and voice terminal features as if the cluster is a single large node. This simplifies dialing
procedures between locations, and also allows transparent use of some of the system’s
features between locations.
An example of connecting three System 75 switches in a DCS configuration using voice tie
trunks and DS1 signaling is shown in Figure 5-25. In this example, the switches are
designated as Switch A, B, and C. Switch A is the master switch and switches B and C are
slaves. Figure 5-25 also references the screen forms used to assign parameters for DCS
signaling and voice tie trunks. These forms are provided as an example only and are in
Parts 2 and 6 of this manual. The forms show how to implement Switch A to communicate
with Switches B and C. Switches B and C in turn must be implemented to communicate with
Switch A.
Figure 5-25 does not cover every example of how DCS can be configured. This example is
intended to show how the various screen forms can be used to implement DCS. The screen
forms associated with this example do not show all the information that can be entered on
the form. The fields on the screen forms that can be completed for DCS have been filled in.
The other fields that can be filled in depend on how the system is configured to meet your
particular needs.
For detailed information on DCS, refer to the AT&T Network and Data Services Reference
75 Application Notes—Distributed
Manual, 555-025-201, and the AT&T System
Communications System, 555-209-003.

• Class of Restriction Form—Assign originating FRLs.
• Routing Patterns Form—Assign terminating FRLs.

Guidelines and Examples
The examples given here are designed to help understand FRLs and to illustrate some of the
practical aspects of FRLs. These are, however, only examples. In reality, each system must
be administered to meet individual needs.
The FRL assigned to the facility answering a call is not checked. Terminating-side FRLs
apply to trunk groups only. This simplifies assignments. At each switch, the trunk groups
available to handle a given call must be listed in the preferred order within the Routing
Pattern. The most-preferred choice must be at the top of the list. Up to six choices can be
specified. Now the relative value of access to each of the listed trunk groups must be
determined. This, of course, is specified via an FRL. On a scale of O through 7, the relative
value is determined and assigned. Decisions are normally based on the cost of using the
facility, although other criteria can be used. The same FRL value can be assigned to more
than one trunk group if there is no reason to prefer one trunk group over the other.
If there will be users within the system who are not allowed to make outside calls, use some
value other than O as the value for the first-choice trunk group. By assigning these users an
FRL of O, none of the trunk groups can be accessed (since all trunk group FRLs will be
greater than O). Such calls are denied.

5-159

CHAPTER 5. SYSTEM FEATURES, FUNCTIONS, AND SERVICES

Each Routing Pattern must be individually constructed. The same trunk group can be used
in more than one pattern. The associated FRL is assigned within the pattern and is not
associated with the trunk group itself. The same trunk group can have a different FRL in a
different pattern.
Be consistent in FRL assignments. Do not use a range of O through 5 in one pattern and a
range of 2 through 7 in another pattern if all users can access the first-choice route.
Admittedly, the trunk group with an FRL of 2 may be more expensive than the trunk group
with an FRL of O, but there is no real reason to assign a 2 to a trunk group that everyone
can access. For ease of assignments, always use a O for such a trunk group.
There should be a class of restriction (COR) established for each FRL used in a Routing
Pattern. The appropriate COR is then assigned to the users who can access the routes
restricted by the FRL value. For example, a middle executive might be able to access all
routes with an FRL of 5 or lower, whereas the president can access all routes. In this case,
the executive is assigned a COR with an FRL of 5 and the president is assigned a COR with
an FRL of 7.
Remote Access users can access the system’s features and services the same as an onpremises user. FRL assignment is via Remote Access Barrier Codes. Up to 10 Barrier
Codes, each with its own COR (and FRL), can be assigned. Although the COR defines other
restrictions, 10 Barrier Codes are enough to also provide a range of FRL assignments.
Assignment of Barrier Code FRLs is the same as if the user were on-premises. The simplest
way to assign these FRLs is to duplicate the on-premises FRLs, and then merely relate the
appropriate Barrier Code to those that will be using Remote Access.
FRLs apply only on ARS and AAR calls. If Station Message Detail Recording (SMDR) 15digit account codes are used, the FRL field in the SMDR record is overwritten.
The following is an example of how FRLs can be assigned:
• FRLO—NO outgoing calls.
•

FRL1—Local calls only.

• FRL2—FRL1 plus the home area code calls using WATS.
•

FRL3—FRL2 plus the use of local lines for all calls in the home area code.

•

FRL4—FRL3 plus the calls to all of the U. S. A., using WATS only.

FRL5—FRL4 plus the calls to all the of the U. S. A., using local lines.

• Zero Code Suppression—Enter “b8zs” (bipolar eight zero substitution) or “ZCS ”
(zero code suppression). This method must match the method used on the other end
of the link. This entry indicates which line coding format will be used to ensure that
the data meets T1 -carrier requirements. Enter zcs for the three types of
MEGACOM® telecommunications services. Enter b8zs for DDM/000. Use zcs for
No. 3 ESS®, D4, or DACS systems; zcs is a line coding method that checks for all
zeroes in an 8-bit time slot and, if all zeroes exist, bit 2 is changed from O to 1.

DS1 Circuit Pack

Binary eight zero code suppression is an alternate line coding technique that uses a
bipolar violation to ensure adequate “ones” density is a bit sequence. Eight zeroes
in an 8-bit sequence triggers the bipolar violation. Zero code suppression is a line
coding method that checks for all zeros in an 8-bit time slot and, if all zeros exist, bit
2 is changed from a O to a 1. This method of line coding ensures. adequate timing
recovery of regenerative 56-bps or less digital facilities.
This parameter selects the method used for handling all-zero codes in order to
preserve timing information on the DS1 link. If there is a free choice at both ends,
b8zs is recommended because it provides data transparency. However, b8zs does
cause an error (a “bipolar violation”). Using zcs does not cause an error.
•

Framing Mode—Enter “d4” or “esf.” This mode must match the method used on
the other end of the link. The network diagram should indicate which choice for the
particular DS1/T1 -span. Enter D4 for the three types of MEGACOM services. D4 is
a framing format of 12 frames for analog representation on T1 carrier using DS1
signals. ESF is an extended frame format on T1 carrier using DS1 signals in which
24 frames are used to convey signaling for the channels.

• Signaling Mode—Enter “common-than” or “robbed-bit.” This mode must match the
method used on the other end of the link. For voice tie trunks, enter “robbed-bit”
and “common-than” for alternate voice data (avd) trunks. Enter “robbed-bit” for the
three types of MEGACOM services. Robbed-Bit Signaling is a per-channel signaling
technique for transmitting signaling bits within each band on each of the 24 channels
in a DS1 facility. The least significant bit in every sixth transmitted information frame
is “robbed” and replaced by a signaling bit.
•

DM1-BOS—Enter “y” to activate the DMI BOS mode when the signaling mode is
common-channel and a TN722B circuit pack has been installed. When “n” is
entered, indicates the DS1 will provide the AT&T proprietary format;’ “y” indicates the
DS1 /DM1 interface will provide the DMI format. Enter “n” for the three types of
MEGACOM services. DM1/BOS provides a 24th channel signaling scheme using a
DS1 facility which uses 23 message channels and 1 signaling channel (24th).
DM1/BOS has greater capacity (ability to carry 64 kbps channels) than the 24th
channel Robbed-Bit Signaling scheme.

•

Slip Detection—Enter “y” to enable the slip-rate status of this circuit pack to be
used by maintenance software to determine whether an excessive frame slip rate
exists. Enter “n” when DMI is used or when testing is not required. Enter “y” for
the three types of MEGACOM services.
Note:

Those DS1/T1 facilities that are used to provide the primary and
secondary synchronization reference should be administered for slip
detection “y.” Typically, those other DS1/T1 spans that are used for
data applications and which are deemed very important should also
be administered for slip detection. This excludes all T1 -spans
connecting channel banks, unless the channel bank is externally time.
Normally, those DS1/T1 spans that are used exclusively for voice and
which are not designed as the primary or secondary synchronization
source should be administered for slip detection ‘{y. ” Refer to the

6-87

CHAPTER 6. SYSTEM FORMS

network synchronization diagram in order to determine which option to
choose.
The digital switch maintains a slip count record for each DS1 interface. The slip
count is used to determine if the T1-span is experiencing errors and, if so, the
severity of the errors (type alarm). Option “y” enables switching between the
primary, secondary, or internal high-accuracy clock.
Note:

If as many as 50 percent of those spans that are administered for
slip detection are experiencing slips (with respect to the primary),
then a decision is made to switch to the secondary.

• Remote Loop-Around Test—Enter “y” to allow testing or “n” to deny testing.
This test is not possible unless the DSI is connected to appropriate equipment
such as a DSX-1 cross-connect or a DMI interface. The response should be “n”
unless the testing is extremely important. Enter “n” for the three types of
MEGACOM services. Enter “y” if a CSU is connected.

Hunt Groups
Purpose
Hunting checks for the busy or idle status of extension numbers in the hunt group. Uniform
Call Distribution (UCD) selects the “most idle” extension. Direct Department Calling (DDC)
selects the first available extension (in the administered sequence).
This form is used to create Hunt Groups which are identified by a Hunt Group number from 1
to 32. Users assigned to a Hunt Group are identified by their extension number. Up to 100
users can be assigned to a Hunt Group. Up to five hunt groups can be assigned for the
Hospitality Parameter Reduction feature.
Several different hunt group forms can be used to implement a hunt group and its associated
features such as Automatic Call Distribution (ACD) and hunt group queuing. Look at the
various hunt group forms and choose the forms that can be used to implement your hunt
group requirements.
Once the forms have been chosen, review the instructions below and use the instructions for
the fields that appear on the forms. The instructions listed below describe ail the fields that
can be used; however, some of the fields may not appear on the forms you selected. The
Implementation Note at the bottom of some of the screen forms shows the fields that can be
used when the ACD, Queue, and Call Management System (CMS) parameters are assigned
using different combinations of y (yes) and n (no).
Instructions
Make assignments as required for the following fields:
