• Flexible channel allocation (any starting channel and al­ternate or contiguous).

ESU LT Interfaces

The ESU LT is equipped with four interfaces:

• E1 Network interface per ITU G.703

• Nx56/64 high-speed, multiprotocol serial interface

• Control input (EIA-232)/Chain port input

• Chain port output

See Figure 1-3 and the following descriptions in this section.

Chapter 1. Introduction

ESU LT

ESU LT

Figure 1-3. ESU LT Int e rfaces

61200410L1-1 ESU LT User Manual 1-3

Network Interface (NI)

The Network Interface (NI) port provides the connection to
the E1. This port complies with the applicable ANSI and
CCITT standards. Either the 120Ω DB15 or the 75Ω BNC
interface (adapter provided) may be used for the Network
Interface. The 75/120 selection must be made with the front
panel menus. For more information, see Wiring on page C-1.

Network Test Interface

The MON test jack provides a bridges access jack for non­intrusive monitoring of the incoming E1.

Nx56/64 Serial Interface

The Nx56/64 provides a serial interface that operates from
56kbps to 2.048 Mbps. The Nx56/64 can be configured as a
V.35, V.36, EIA-530, or V.11 electrical interface through the
front panel menus.

Control Por t Input

The control port input provides an EIA 232 input from a PC
or a modem for control of the ESU LT. You can also use it as a
chain input from another ESU LT or ESU 120e. For more
information, see Wiring on page C-1.

Chapter 1. Introduction

Chain Port Output

The chain port output provides an EIA-232 output to chain
control to other ESU LTs or ESU 120es. For more information,
see Wiring on page C-1.

Software Management

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 also displays the status of operation and
performance reports for the unit. A complete discussion of
the operation of the front panel is found in Chapter 3,

Operation on page 3-1. The menu options are found in
Chapters 4 through 7.

1-4 ESU LT User Manual 61200410L1-1

T- Watch Pro Management Software Program

T-Watch Pro is the ADTRAN management software program
that allows the user to control the ESU LT from a PC. It
provides complete control over the configuration of the ESU
LT using a graphic interface. The T-Watch Pro program
displays the same status and performance data as the front
panel LCD. This data is displayed as tables and graphs.

The T-Watch Pro program has the following capabilities:

• Interfaces with a modem which permits dialing into a re­mote ESU LT location to configure the unit or read the
unit’s status or performance.

• The performance data read from the units can be exported
in a file which is compatible with common spread sheet
programs.

ESU LT Testing

The ESU LT offers three forms of testing:

•Self-test

• Loopback tests

• Pattern generation and check

Chapter 1. Introduction

Self-test

The self-test checks the integrity of the internal operation of
the electronic components by performing memory tests and
by sending and verifying data test patterns through all
internal interfaces. Although actual user data cannot be
passed during these tests, the self-test can run with the
network and DTE interfaces in place, without disturbing any
external interface.

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

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

61200410L1-1 ESU LT User Manual 1-5

Loopback Tests

Chapter 1. Introduction

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

• Monitoring the phase-locked loop for lock.

• Standard background network performance monitoring.

A number of different loopbacks can be invoked locally from
the front panel, by T-Watch commands, or remotely using
V.54 loopback code.

Network L o op ba cks

There are two types of network loopbacks. See Figure 1-4.

E1

Payload Loopback

Similar to line loopback, except that the framing is extracted
from the received data and then regenerated for the
transmitted data.

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.

ESU

Figure 1-4. Network Loopback Tests

1-6 ESU LT User Manual 61200410L1-1

DTE Int erface Lo op back

The Nx56K/64K serial interface offers a DTE loopback. See
Figure 1-5.

DTE Loopback

Loops all data from the DTE back towards the DTE. This
loopback may be initiated by using the front panel or T-Watch
commands. The DTE (or the external test equipment) must
provide a test pattern to check the DTE interface.

Chapter 1. Introduction

ESU

Figure 1-5. DTE Interface Loopback

61200410L1-1 ESU LT User Manual 1-7

Pattern Generation

The ESU LT offers five test patterns: 511, QRSS, 1:8, All Ones,
and All Zeros.

Chapter 1. Introduction

511

QRSS

1:8

All Zeros
All Ones

The 511 pattern is generated and checked by the Nx56K/
64K serial interface. It only appears in the TS0s assigned to
the Nx56K/64K port.

When used in conjunction with the payload loopback at
the far end, an end-to-end integrity check can be made on
the DTE ports.

The ESU LT has an internal QRSS pattern generator and
detector. The pattern appears only in the TS0s assigned to
the Nx56K/64K port. The QRSS test pattern can be used in
conjunction with network loopbacks to perform end-to­end tests.

The 1:8 is a stress pattern which places the maximum num­ber of 0s in the transmitted data. This is always done over
all time slots.

This pattern is used in conjunction with external test equip­ment to determine if the E1 line is performing acceptably
under a stress condition. Each channel of the E1 has only
one bit set.

Generates an all zeros pattern in every channel.
Generates an all ones pattern in every channel.

1-8 ESU LT User Manual 61200410L1-1

Bridge/Router Ap plication

A bridge or router can be interfaced to the network by using
the DTE interface. The bandwidth used is programmable at
Nx56 or Nx64 data rates for E1 or FE1 service. The
bandwidth can be selected as contiguous or alternate. Figure
1-6 shows a simple bridge application.

FRAMING

Chapter 5. Configuration Menu

The ESU LT can operate in three different framing modes:
Common Channel Signaling (CCS), Channel Associated
Signaling (CAS), or unframed.

CCS

CCS uses a 7-bit pattern called the Frame Alignment Signal
(FAS) in order to establish and maintain frame
synchronization. The FAS word is located in timeslot 0 of
even frames. Odd numbered frames may contain the Not
FAS word (NFAS) in timeslot 0. The ESU LT can be
configured to require the NFAS word for frame sync.

In CCS mode, there are 31 channels (timeslots 1-32) available
for user data. Timeslot 16 cannot be used to carry signaling
information in this mode.

CAS/TS16

CAS, also known as timeslot 16 multiframing, requires a
multiframe alignment signal to be present for frame sync.
The Multiframe Alignment Signal (MFAS) is inserted into the
16th timeslot of frame 0 of the 16-frame multiframe. The
MFAS word consists of four zeros, an unused bit, the
multiframe alarm bit and two more unused bits. Frames 1
through 15 carry the A,B,C and D bits for timeslots 1-15 and
17-32.

The ESU LT is designed for data transmission; therefore, the
signaling bits used for voice traffic are set to

all ones

.

In CAS mode, there are 30 channels available for user data. If
timeslot 16 is included in the unit’s mapping, it will be
disregarded. For example, if the starting TSO is set to 1 and
the number of TSOs is set to 20. User data will be mapped to
timeslots 1-15 and 17-21.

UNFRAME

The ESU LT can operate in unframed mode. In this mode,
user data is inserted into all 32 channels of the E1 stream.
Since the object of running without framing is to utilize the
full bandwidth of the E1 line, the starting TSO and number of
TSOs option settings are ignored.

612004 10L1-1 ESU LT User Manua l 5-3

Chapter 5. Configuration Menu

Other option settings that have no effect in unframed mode
include: CRC4, NFAS WORD, RFA GEN, AUTO DTE TX
CLK, MAPPING, DATA INVERT, INBAND.
Choices: CCS; CAS/TS16; UNFRAMED

LINE CODE

Selects either AMI or HDB3 line coding.
Choices: HDB3; AMI

CRC-4

When enabled, the CRC-4 checksum bits are transmitted in
the outgoing E1 data stream. Also the received signal is
checked for errors. CRC-4 can be enabled in both CCS and
CAS modes. A CRC-4 checksum cannot be sent in unframed
mode.
Choices: Enable; Disable

NFAS WORD

If enabled, the network interface receiver requires the NFAS
word (time slot 0 in odd frames) and the FAS word
(time slot 0 in even frames) for frame sync. When disabled,
only the FAS word is needed for frame sync.
Choices: Enable; Disable

RFA GEN

When enabled, remote frame alarm is transmitted toward the
network during alarm.
Choices: Enable; Disable

TIMING MODE

Selects the clock source for transmission toward the network
from the NI.
Choices: Network, Internal; DTE

The clocking option selected always designates the clock source for
transmission. Clocking necessary for receiving data is always re­covered from incoming data.

5-4 ESU LT User Manual 61200410L1-1

Chapter 5. Configuration Menu

Network T i min g

The network is the source of timing. The received data
clocking is looped back to the network where it is used to
determine the transmission timing. This option is also
referred to as looped timed as the transmission clock is
derived from the received clock. See Figure 5-3.

.



Figure 5-3. Network Timed Clock Source

Internal Timing

The ESU LT is the source of timing. The ESU LT is configured
to use its own internal oscillator as the source of timing.
Applications include private line driver circuits where one
end is set to network and the other to internal.
See Figure 5-4.

DTE Timing

The DTE is the source of timing. The ESU LT uses th
incoming DTE clock to determine the transmission timing.
This is typically used in applications such as limited distance
line drivers, where it is necessary to have the DTE as the
primary clock source. See Figure 5-5.

occupied operates in 56K mode and the DTE clock rate is
reduced by 8 kbps. The ESU LT uses this 8 kbps channel to
send and receive configuration data across an E1 span. As
shown in Figure 5-7 on page 5-11, this allows the PC
connected to the chain-in port on ESU LT A to monitor/
configure both ESU LT A and B.

The 8 kbps channel is only taken out of the first time slot. If
two 64K TS0s are mapped, the DTE rate would be 120 kbps
instead of 128 kbps. This menu option can also be set to

Network Tests

Network tests are used to control the activation of loopbacks
and the initiation of data test patterns.

The network tests are run on the network interface (NI).
Three different test configurations can be selected to
determine the type of loopback and the pattern to run. Test
results are displayed in the LCD window. See Figure 7-2.

FE1 Loop back

FE1 loopback sends V.54 loopback code in all mapped TS0s
toward the network. The far end unit will respond by
initiating a local line loopback. This loopback is not available
when operating in unframed mode.

TEST P ATTERN

Sets the pattern for the test and initiates the transmission of
the pattern. There are four patterns available. The test is
terminated by selecting

1:8 ALL TS0s

Generates a 1 in 8 pattern in all TS0s.

QRSS ACT TS0

The ESU LT has an internal QRSS pattern generator and
detector. The pattern only appears in the TS0s assigned to the
Nx56K/64K port. The QRSS test pattern can be used i
conjunction with network loopbacks to perform end-to-end
tests.

Example Operations

TESTING EXAMPLES

Before using the ESU LT to pass data, it is recommended to
run tests on the circuit. Testing consists of sending a test
pattern from end-to-end and checking for errors in the
pattern. There are two types of tests used to accomplish this:

• Loop-up the far end and then send a test pattern.

• Send a test pattern from both ends and check at bot

ends.

Far End Looped Back Test

Two types of tests can be executed with the far end looped.
The first is a check of the network and the network interfaces
at both ends. The second is a check of the DTE port.

Network Interface Test

The Network Interface Test can be run with any channel
setup because the 511 and QRSS patterns are always sent i
the occupied channels.
