Chapter 1 Introduction

T1/FT1 OVERVIEW

T1 digital communication links have been used by telcos for the transmission of voice since the early

sixties. The D4 channel bank is an example of a T1 digital carrier system that was introduced in the mid-

seventies and is still widely used by the telcos. Communication demands of business continued to grow to

the point that the telcos began offering T1 service directly to the public. D4 channel banks were used for

T1 in corporate network topographies for voice. The technological advances in computer development also

created a demand for T1 data communication, which now is a large part of the T1 traffic.

T1 SERVICE OFFERINGS

T1 is a digital service delivered to the user over two pairs of wires from the service provider. The signal

operates at 1.544 Mbps and is usually extended by repeaters installed approximately every mile after the

first 6000 feet. The T1 signal is divided into 24 time slots which operate at 64 kbps (DS0s). Each time slot

is occupied by digitized voice or by data.

The T1 signal originally used a type of framing known as D4 superframe (SF), which identifies how the T1

is multiplexed. An enhancement of that framing format, called extended superframe (ESF), is available.

ESF provides a non-disruptive means of full-time monitoring on the digital facility. It was originally used

by service providers to monitor the performance of their service offering. Since the introduction of ESF,

equipment installed in private networks can also provide this performance information to the user.

T1 ESF CSU ACE OVERVIEW

Most carriers (regional or local telcos), when supplying a T1 line to customer premises equipment (CPE),

require an interface to monitor the T1 line. The T1 ESF CSU ACE (extended superframe channel service

unit advanced communication equipment) provides the required interface between the CPE (such as DSUs,

channel banks, T1 multiplexers, and PBXs) and telco or private T1 facilities. Figure 1-1 depicts a typical

application.

Chapter 1. Introduction T1 ESF CSU ACE User Manual

Figure 1-1. T1 ESF CSU ACE Application

The T1 ESF CSU ACE provides surge protection, signal regeneration, alarms, and loopbacks necessary for

circuit operation and fault isolation. The unit provides the simultaneous use of performance report

messages of ANSI T1.403 and maintenance messages of AT&T TR54016. The T1 ESF CSU ACE also

provides conversion from SF to ESF framing formats, allowing older SF data terminal equipment (DTE) to

take advantage of the superior diagnostic capabilities of ESF T1 facilities.

The unit complies with Part 68 of FCC Rules and with applicable sections of AT&T 62411, ANSI T1.102,

and T1.403.

• AMI or B8ZS coding

• Transmit LBO to 655 feet

• DTE loopback

Control Port Input (Labeled EIA-232)

Features of the control port include the following:

• EIA-232 input from a PC or a modem for control of the T1 ESF CSU ACE

• Up to 9600 baud operation

• Acts as input for PC or proxy agent control

• VT100 terminal interface

T1 ESF CSU ACE User Manual Chapter 1. Introduction

FOUR METHODS OF CONTROL

Front Panel

The front panel provides complete and easy control of all items that can be configured through

menu-guided options. The front panel LCD displays the status of operation and performance reports for the

unit. Chapter 3 contains information on front panel operation and all the menu options.

ADTRAN PC Program

T-Watch is the ADTRAN PC control program. It provides complete control over the configuration of the

T1 ESF CSU ACE through a graphic interface. The T-Watch program displays the same status and

performance data as the front panel LCD. This data is displayed in the form of tables and graphs.

The T-Watch program has the following capabilities:

• Interface with modem permits dialing into a remote T1 ESF CSU ACE location to configure the unit or

read the unit’s status or performance.

• Performance data read from the units can be exported in a file which is compatible with common

spreadsheet programs.

SNMP

The ADTRAN T1 ESF CSU ACE supports the Simple Network Management Protocol (SNMP) through

the ADTRAN Advisor SNMP Proxy Agent (1950007L1) to a network management system such as

OpenView® or SunNet Manager™. The proxy agent runs on a PC and can interface to the T1 ESF CSU

ACE directly or through a modem, in the same manner as the T-Watch PC programs.

ASCII Terminal

The ADTRAN T1 ESF CSU ACE recognizes an escape sequence that puts the unit into the ASCII terminal

mode. After receiving the sequence, the T1 ESF CSU ACE sends front panel information to the terminal.

This interface acts exactly like the front panel, but the advantage is that it can be accessed remotely

(through a modem). The escape sequence is:

<CONTROL-A> <CONTROL-P> <CONTROL-T>

<CONTROL-P> <CONTROL-T> <CONTROL-T>

The terminal or terminal emulation software must be VT100 compatible.

Chapter 1. Introduction T1 ESF CSU ACE User Manual

T1 ESF CSU ACE TESTING

The T1 ESF CSU ACE offers three forms of testing:

•Self test

• Loopback tests

• Pattern generation

Self Test

The self test checks the integrity of the electronic components’ internal operation by performing memory

tests and sending and verifying data test patterns through all internal interfaces. Although actual user data

cannot be passed during these tests, the self test can be run with the network and DTE interfaces in place

and will not disturb any external interface.

The self test automatically executes upon power-up. It can also be initiated from a front panel menu or

from the control port.

In addition to the specified self tests, background tests are run on various parts of the internal electronics.

These run during normal operation to confirm continued correct functioning. The background tests include

the standard background network performance monitoring as required by ANSI T1.403 and AT&T 54016,

for which the results are stored.

T1 ESF CSU ACE User Manual Chapter 1. Introduction

Loopback Tests

A number of different loopbacks can be invoked locally from the front panel, by T-Watch commands, or

remotely by using special inband codes (AT&T network loop-up and loop-down codes). Additionally, the

loopbacks can be remotely controlled by out-of-band commands using the T1 ESF FDL, or from T-Watch

using a modem connection. A discussion of network loopbacks and DTE interface loopbacks follows.

Network Loopbacks

There are two types of network loopbacks: line loopbacks and payload loopbacks. These are illustrated in

Figure 1-5.

• Line Loopback - Loops all of the received data back toward the network. The transmitted data is the

identical line code that was received, including any bipolar violations or framing errors.

• Payload Loopback - Similar to line loopback, except that the framing is extracted from the received data

and then regenerated for the transmitted data.

Figure 1-5. Network Loopback Tests

DTE Interface Loopbacks

Loops all data from the terminal interface (TI) back towards the T1. This loopback may be initiated using

front panel, EIA-232 control port, or T-Watch commands. The DTE (or external test equipment) must

provide any test pattern in order to check the DTE interface. See Figure 1-6.

Figure 1-6. DTE Interface Loopback

Chapter 1. Introduction T1 ESF CSU ACE User Manual

Pattern Generation

The T1 ESF CSU ACE offers three test patterns: All Ones, All Zeros, and 1:8. These patterns can be

initiated from the front panel, through the EIA-232 control port, or remotely via a management software

like T-Watch.

All Ones

The All Ones pattern sends ones in all the payload bits.

All Zeroes

The All Zeros pattern sends zeros in all the payload bits and is useful for testing line code configuration

(AMI/B8ZS mismatches).

1 in 8 (1:8)

Each channel of the T1 has only one bit set. This pattern is used in conjunction with external test

equipment to determine whether the T1 line is performing acceptably under a stress condition.

APPLICATIONS

Three applications are shown in this section. Figure 1-7 on page 27 shows a general data application;

WIRING

The connectors are described in this section.

RJ-48C Connectors

Two RJ-48C connectors are located on the back end of the T1 ESF CSU ACE. The NET connector

connects the unit to the network. The connector marked CPE connects the unit to the data terminal

equipment. These connectors have exactly the same pinouts.

See Table A-1 on page 51 for the RJ-48 connector pin assignments.

EIA-232 Connector

The EIA-232 connector is used to connect the T1 ESF CSU ACE to a proxy agent, T-Watch, an ASCII

terminal, or a modem.

See Table A-2 on page 51 for the connector pin assignments.

Connector Type = Female DB-9

Method 2

• Connect to a reliably-grounded 12-48 Vdc source which is electrically isolated from the AC source having

LPS or NEC Class 2 outputs

• Use a Listed Class 2 Direct Plug-In Supply with an output rated 12-48 Vdc, minimum 350 mA, maximum

240 VA.

Note: The branch circuit overcurrent protection shall be a fuse or circuit breaker rated at a minimum of 48 V to

a maximum of 10 A.

A readily accessible disconnect device that is suitably approved and rated, shall be incorporated in the field

wiring.

The unit shall be installed in accordance with the requirements of NEC NFPA 70, where applicable.

To use the cable of the supplied power supply with a local supply, connect the black wire to the negative pole of

the power supply and connect the black and white wire to the positive pole of the power supply. The outside

contact point of the barrel plug connects to the negative pole and the center contact point of the barrel plug

connects to the positive pole.

To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.

T1 ESF CSU ACE User Manual Chapter 2. Installation

POWER-UP TESTING AND INITIALIZATION

When shipped from the factory, the T1 ESF CSU ACE is set to factory default conditions. When power is

applied, the unit automatically executes self test, followed by an initialization sequence that sets up the

unit.

Self Test

Upon a power-up or self test, the LCD displays ADTRAN T1 ESF CSU ACE INITIALIZING and the

LEDs illuminate momentarily. When the self test is completed with no failures detected, the LCD

momentarily displays ALL TESTS PASSED. If a failure is detected, it is displayed in the LCD window.

The automatic self test procedure consists of the following steps:

1. Board level tests - RAM tests; EPROM checksum

2. Unit level tests - Front panel LED verification

1)NI PERF RPTS, Submenu of 1)STATUS

The Network Interface Performance Reports menu item displays the user copy of the performance

data. The T1 ESF CSU ACE maintains this performance data on the network in compliance with ANSI

T1.403 and AT&T document TR54016. The data displayed is data accumulated over the last 15

minutes and over the last 24 hours.

Figure 3-10. First Menu of NI PERF RPTS Menu

These fields cannot be edited, only cleared, as previously discussed. Only the user copy of the

performance data is cleared. The network management performance data history remains unaffected.

Separate carrier totals are kept which can only be retrieved and reset from the network.

Figure 3-11. Performance Counter Screen

The counters used in the performance screens are defined below.

SES Number of severely errored seconds

ES Number of errored seconds

%AV Percent of available seconds

%EF Percent of error free seconds

CVs Number of code violations

Continue with standard operation procedures to exit the display.

Since only the user’s copy of performance data is cleared by the T1 ESF CSU ACE, the

data displayed here might be different from the data being sent to the network as

maintenance message data.

Tests are used to control the activation of loopbacks, the initiation of data test patterns, and self test

execution.

1)LOCAL LOOPBK, Submenu of 4)TEST

Four choices are available for setting the local loopback:

NO LOOPBACK Deactivates the loopback

DTE ON Activates the DTE loopback

LINE ON Activates the line loopback

PAYLOAD ON Activates the payload loopback

Figure 3-20. Local Loopback Test Screen

2)REM LB, Submenu of 4)TEST

Activates the same loopbacks as the LOCAL LOOPBCK but at the far end. This uses either the inband

loop-up code as specified by AT&T 62411 for line loopback (ATT In-Band LLB), or the FDL as

specified in ANSI T1.403 for line loopback codes. An FDL (formerly TABS) maintenance message

corresponding to AT&T TR54016 can be used for payload loopback as well:

NO LOOPBACK Deactivates the loopback.

AT&T INBAND LLB Activates the line loopback using inband code.

ANSI FDL LLB Initiates the transmission of an FDL line loop-up code toward the far end.

AT&T FDL PLB Initiates the transmission of the PLB maintenance messages on the FDL.

When a loopback method is selected, the T1 ESF CSU ACE displays LOOPING in the top

right corner of the LCD and the yellow LOOPBACK LED is turned on. When the T1 ESF

CSU ACE determines that the far-end T1 ESF CSU ACE has looped up, the T1 ESF CSU

ACE displays LOOPED. If the T1 ESF CSU ACE does not recognize the remote T1 ESF

CSU ACE looped up after about 10 seconds, the T1 ESF CSU ACE sends the appropriate

loop-down code and displays FAILED, and the LOOPBACK LED is turned off.

Excessive errors on the T1 line can cause this failure. The FDL loopbacks fail if the FDL

is not intact from one end point to the other. FDL loopbacks are valid only in the ESF

framing mode.

Chapter 3. Operation T1 ESF CSU ACE User Manual

3)TEST PATTERN, Submenu of 4)TEST

Sets the pattern for the test and initiates the transmission of the pattern. The test is terminated by

selecting NO PATTERN. There are four patterns available:

NO PATTERN Terminates pattern generation.

ALL ZEROS Generates an all zeros pattern in every channel.

1:8 ALL DS0s Generates a 1 in 8 pattern in all DS0s.

ALL ONES Generates an all ones pattern in every channel.

4)RUN SELFTEST, Submenu of 4)TEST

Use this menu selection to execute an internal self test. This is the same self test that is performed

automatically at power-up. The results of the self tests are displayed in the LCD (see Figure 3-21).

Upon invoking the command, the LCD displays INITIALIZING and test failures are displayed in the

LCD window.

Figure 3-21. Self Test Result Screen

If a failure is detected, note the failure prior to contacting ADTRAN technical support.

Use up and down

scroll keys To select, for example, 1:8 ALL

DS0s.

Press ENTER To record selection.

Results The T1 ESF CSU ACE starts to gen-

erate a 1:8 test pattern and inserts the

pattern into all DS0s.

Select

NO PATTERN To end the test.

The execution of a self test disrupts normal data flow and prevents remote communication

until the self test is completed (approximately five seconds).

to users over 4 copper wires. Compatible with the T1 ESF CSU ACE 4-wire Switched 56 DBU option.

ANSIAmerican National Standards Institute. Devices and proposes recommendations for international communica-

tions standards.

asynchronous

A method of data transmission which allows characters to be sent at irregular intervals by preceding each char-

acter with a start bit, followed by a stop bit.

bandwidth

The bandwidth determines the rate at which information can be sent through a channel (the greater the band-

width, the more information that can be sent in a given amount of time).

BECN

backward explicit congestion notification. A bit set by a frame relay network to notify an interface device

(DTE) that congestion avoidance procedures should be initiated by the sending device.

bridge

A device that supports LAN-to-LAN communications. Bridges may be equipped to provide frame relay support

to the LAN devices they serve. A frame relay capable bridge encapsulates LAN frames in frame relay frames

and feeds them to a frame relay switch for transmission across the network. A frame relay capable bridge also

receives frame relay frames from the network, strips the frame relay frame off each LAN frame, and passes the

LAN frame on to the end device. Bridges are generally used to connect LAN segments to other LAN segments

or to a WAN. They route traffic on the Level 2 LAN protocol (e.g. the Media Access Control address), which

occupies the lower sub-layer of the LAN OSI data link layer. See also router.

CCITT

Consultive Committee for International Telephony and Telegraphy. A standards organization that devises and

proposes recommendations for international communications. See also ANSI.

CD carrier detect. A signal generated by a modem or DSU/CSU. CD indicates the presence of a carrier signal on a

communications link.

clocking

An oscillator-generated signal that provides a timing reference for a transmission link. A clock provides signals

used in a transmission system to control the timing of certain functions. The clock has two functions, (1) to gen-

erate periodic signals for synchronization and (2) to provide a time base.

CPE customer premise equipment. All telecommunications terminal equipment located on the customer premises,

including telephone sets, private branch exchanges (PBXs), data terminals, and customer-owned coin-operated

telephones.

Appendix D. Glossary T1 ESF CSU ACE

CRC cyclic redundancy check. A computational means to ensure the accuracy of frames transmitted between devices

in a frame relay network. The mathematical function is computed, before the frame is transmitted, at the origi-

nating device. Its numerical value is computed based on the content of the frame. This value is compared with a

recomputed value of the function at the destination device. See also FCS.

CS See CTS.

CSU channel service unit. A device used to connect a digital phone line (T1 or Switched 56 line) coming in from the

phone company to either a multiplexer, channel bank, or directly to another device producing a digital signal;

for example, a digital PBX, a PC, or data communications device. A CSU performs certain line-conditioning

and equalization functions, and responds to loopback commands sent from the central office. A CSU regener-

ates digital signals. It monitors them for problems, and provides a way of testing the digital circuit.

CTS clear to send. A signal on the DTE interface indicating that the DCE is clear to send data.

dB decibel. A unit of measure of signal strength, usually the relation between a transmitted signal and a standard

signal source.

company lines and for converting signals between telephone lines and DTE. Also see DTE.

DDS digital data service. A private line digital service, for transmitting data end-to-end at speeds of 2.4, 4.8, 9.6, and

56 kbps and in some cases 19.2, 38.4, or 64 kbps. The systems can use central hub offices for obtaining test

access, bridging legs of multipoint circuits, and cross connecting equipment. DDS is offered on an inter-LATA

basis by AT&T and on an intra-LATA basis by the Bell operating companies.

DE discard eligibility. A user-set bit indicating that a frame may be discarded in preference to other frames if con-

gestion occurs, to maintain the committed quality of service within the network. Frames with the DE bit set are

considered excess data.

DLCIdata link connection identifier. A unique number assigned to a PVC end point in a frame relay network. Identi-

fies a particular PVC endpoint within a user’s access channel in a frame relay network and has local signifi-

cance only to that channel.

DSU data service unit. A device designed to transmit and receive digital data on digital transmission facilities.

DSU loopback

A telco initiated test which loops the DSU back to the telco and is used to test the DDS circuit as well as the

DSU/CSU.

T1 ESF CSU ACE Appendix D. Glossary

DTE data terminal equipment. The end-user terminal or computer that plugs into the termination point (DCE) of a

communications circuit. The main difference between the DCE and the DTE is that pins two and three are

reversed.

encapsulation

A process by which an interface device places an end device’s protocol-specific frames inside a frame rely

frame. The network accepts only frames formatted specifically for frame relay; therefore interface devices act-

ing as interfaces to a frame relay network must perform encapsulation. See also interface device or frame relay

capable interface device.

end device

The ultimate source or destination of data flowing through a frame relay network sometimes referred to as

DTE. As a source device, it sends data to an interface device for encapsulation in a frame relay frame. As a des-

tination device, it receives de-encapsulated data (i.e., the frame relay frame is stripped off, leaving only the

user’s data) from the interface device.

FCS frame check sequence. The standard 16-bit cyclic redundancy check used for HDLC and frame relay frames.

The FCS detects bit errors occurring in the bits of the frame between the opening flag and the FCS, and is only

effective in detecting errors in frames no larger than 4096 octets. See also CRC.

FDL facility data link. A 4 bit/s non-disruptive management channel provided in ESF framing mode. This data link

conforms to ANSI T1.403 and AT&T TR 54016 specifications.

FECN

forward explicit congestion notification. A bit set by a frame relay network to notify an interface device (DTE)

that congestion avoidance procedures should be initiated by the receiving device. See also BECN.

file server

In the context of frame relay network supporting LAN-to-LAN communications, a device connecting a series

of workstations within a given LAN. The device performs error recover and flow control functions as well as

end-to-end acknowledgment of data during data transfer, thereby significantly reducing overhead within the

frame relay network.

frame-relay-capable interface device

A communications device that performs encapsulation. Frame-relay-capable routers and bridges are examples

of interface devices used to interface the customer’s equipment to frame relay network. See also interface

device and encapsulation.

frame relay frame

A variable-length unit of data, in frame-relay format that is transmitted through a frame relay network as pure

data. Contrast with packet. See also Q.922A.

frame relay network

information processing equipment in a limited geographic area.

out-of-band

Signaling that is separated from the channel carrying information (voice, data, video, etc.). Typically the sepa-

ration is accomplished by a filter. The signaling includes dialing and other supervisory signals.

packet

A message containing both control information and data. The control information is used for routing the packet

through a network to its final destination. Contrast with frame relay frame.

packet-switching network

A telecommunications network based on packet-switching technology, wherein a transmission channel is occu-

pied only for the duration of the transmission of the packet. Contrast with frame relay network.

parameter

A numerical code that controls an aspect of terminal and/or network operation. Parameters control such aspects

as page size, data transmission speed, and timing options.

T1 ESF CSU ACE Appendix D. Glossary

ping An internet protocol standard that provides loopback on demand for any device in an IP network. One device

“pings” another by sending a loopback request to the device's IP address.

point-to-point

Type of communications link that connects a single device to another single device, such as a remote terminal

to a host computer.

PVC permanent virtual circuit. A frame relay logical link, whose endpoints and class of service are defined by net-

work management. Analogous to an X.25 permanent virtual circuit, a PVC consists of the originating frame

relay network element address, originating data link control identifier, terminating frame relay network element

address, and termination data link control identifier. Originating refers to the access interface form which the

PVC is initiated. Terminating refers to the access interface at which the PVC stops. Many data network custom-

ers require a PVC between two points. Data terminating equipment with a need form continuous communion

use PVCs. See also DLCI.

remote configuration

A feature designed into ADTRAN DSU/CSU products that allow remote DSU/CSU to be configured from a

local DSU/CSU or VT100 compatible terminal.

router

A device that supports LAN-to-LAN communications. Routers may be equipped to provide frame relay support

to the LAN devices they serve. A frame-relay-capable router encapsulates LAN frames in a frame relay frames

and feeds those frame relay frames to a frame relay switch for transmission across the network. A frame-relay-

capable router also receives frame relay frames from the network, strips the frame relay frame off each frame to

produce the original LAN frame, and passes the LAN frame on to the end device. Routers connect multiple

LAN segments to each other or to a WAN. Routers route traffic on the Level 3 LAN protocol (e.g., the internet

protocol address). See also bridge.

Appendix D. Glossary T1 ESF CSU ACE
