CANADIAN EQUIPMENT LIMITATIONS
Notice: The Industry Canada Certification label identifies certified equipment. This
certification means that the equipment meets certain telecommunications network
protective, operational, and safety requirements. The Department does not guarantee the
equipment will operate to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment
must also be installed using an acceptable method of connection. In some cases, the
company's inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (telephone extension cord). The
customer should be aware that compliance with the above conditions may not prevent
degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance
facility designated by the supplier. Any repairs or alterations made by the user to this
equipment, or equipment malfunctions, may give the telecommunications company
cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of
the power utility, telephone lines and internal metallic waterpipe system, if present, are
connected together. This precaution may be particularly important in rural areas.
Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or an
electrician, as appropriate.
The Load Number (LN) assigned to each terminal device denotes the percentage of the
total load to be connected to a telephone loop which is used by the device, to prevent
overloading. The termination on a loop may consist of any combination of devices
subject only to the equipment that the total of the LNs of all devices does not exceed
100.

Introduction
ESU 120e OVERVIEW
The ESU 120e is an E1/FE1 multiplexer with an Nx56/64 data port,
a drop (PBX) interface, one option slot, and embedded SNMP
management. The ESU 120e’s option slot accepts one of many
available option modules for voice and data applications.
The ESU 120e serves as the link between user data sources such as
local area network (LAN) bridges and routers, computers, CAD
systems, teleconferencing equipment, and PBXs. Through the use
of multiple data ports, the ESU 120e can simultaneously connect
one or more of these devices to an E1 circuit. The amount of
bandwidth allocated to each port is custom-programmable. You can
manually allocate bandwidth or set the bandwidth to automatically
change at predetermined times to use the available bandwidth most
advantageously. Changes in the configuration do not disrupt data
flow in channels that are not being reconfigured. The unique
architecture and the availability of option modules provide a path
for growth to accommodate future requirements.
The ESU 120e offers a variety of network management options.
You can manage via Simple Network Management Protocol
(SNMP) through the 10BaseT or chain-in ports. If you are using
T-Watch PRO™, a Microsoft® Windows® program, you can
manage the ESU 120e via the same 10BaseT or chain-in ports. An
enhanced VT-100 terminal interface is also provided.

POWER UP TESTING AND INITIALIZATION
When shipped from the factory, the ESU 120e is set to factory
default conditions. At the first application of power, the unit
automatically executes a memory self-test. A full self-test can
be run from the front panel, and a pass code and unit ID may
be set using the UTIL menu.
Self-Test
Upon a power-up, the LCD displays MEMORY TEST NOW
TESTING and the TEST LEDs are illuminated. When the selftest is completed with no failures detected, the OK LED
illuminates green and the LCD momentarily displays ALL
TESTS PASSED. If a failure is detected, a list of failures is
displayed in the LCD window. The full self-test procedure
(invoked from the front panel or T-Watch PRO) consists of
the following tests:
Board-level tests
Each of the ESU 120e boards contains an on-board processor
which executes a series of tests checking the circuitry on the
board.
RAM and EPROM tests
Verify on-board circuitry.
Unit-level tests
61200420L1-1B
•
Front panel LED verification.
•
Board-to-board interface test. A test pattern is sent from
the controller through a loopback on all other boards and
checked on the controller. This verifies the data path,
clocks, and control signals for the entire chassis.

Chapter 2. Installation
Initialization
Set User Passcode
The ESU 120e is designed to operate with or without the use
of a passcode. The default condition is without a passcode.
If the unit is to be remotely accessed using T-Watch PRO, you
must enter a passcode. When managing a number of units, the
passcode can be the same for all the units.
The passcode should be a number easily remembered. Once
entered, the passcode is required to access any operation
other than viewing. See Set Passcode on page 72 for details.
Set Unit Identification
The Unit ID sets the unit to respond to remote control
(controlled by a device other than the front panel or
terminal). If no Unit ID is recorded it is not possible to
operate from any remote control device, including the local
PC for T-Watch PRO or SNMP. See Unit ID on page 74 for
details.
Set Control Port
The ESU 120e can be configured from the control port when
T-Watch PRO, SNMP, or the terminal interface are being
used.
If the control port is to be used, the control port baud rate
must also be selected.
Chain-In (PC)
The unit can be controlled from an external PC connected
directly or via modem to the chain-in port. When using
chain-in, the selection of the control port baud rate from 9600
(factory default), 1200, 2400, or 4800, or 38400 must be made
using the UNIT CONFIGURATION menu. See Unit on page 62 for
details.

Subsequent ESUs in the chain are in a position to intake
information from another ESU. This in-taking of information
from another ESU in the chain is identified as chain in. The
baud rate for the chained units must match that of the first
unit.
Unless locked out externally, the front panel can also control
the unit.
At this point, the Unit Initialization procedure is concluded.
If the unit is to be configured remotely, there are no
additional items necessary to complete prior to executing
remote configuration.
The Passcode, the Unit ID, and the Control Port settings are
stored in a nonvolatile memory. This assures they are
operable for subsequent power-up sequences.

Data Port Identification
When configuring the unit, menu selections will include options
from data port submenus. Selection of data ports is necessary
because the ESU 120e uses a Slot-Port method to identify the data
port the menu item is referencing. If a module containing a PBX
drop option card with an Nx56/64 plug-on interface is installed in
the option slot, it would be designated as:
drop Passthru=1.1
Where slot=1 and port =1.
The drop is located in the option slot and is the first port in that slot.
Nx56/64=1.2
Where slot=1 and port=2.
The Nx is located in the slot and is the second port in that slot.
The ports that are built into the ESU 120e are referenced as Slot 0.
The Nx56/64 would be designated as 0.1 and the drop would be
referenced as 0.2.

This menu item accesses the configuration of parameters associated with the network interface in the base unit. There are
eight submenu items that include setting the format, the line
build out (LBO), and the timing mode.
Interface (INTFACE)
Selects either the 120Ω DB-15 interface or the 75Ω BNC interface.
Choices: 120Ω, 75Ω. BAL, and 75Ω UNBAL
In 75Ω UNBAL mode, both the Tx and Rx are shield grounded.
NFAS Word (Framing)
If enabled, the network interface receiver requires the NFAS
word (TS0 in odd frames) and the FAS word (TS0 in even
frames) for frame sync. When disabled, only the FAS word is
needed for frame sync.
Choices: ENABLE, DISABLE
CAS/TS16
Enables/Disables Channel Associated signalling (time slot 16
multiframing). When this menu option is enabled, the following events occur.
61200420L1-1B
1.
The TS16 multiframe alignment signal is inserted in the
outgoing data stream.
2.
Signaling Bits are transmitted in TS 16 for all TS0s that
are mapped to a signalling-capable port (Base Drop port,
for example). In TS0s that are mapped to “Idle” or data
ports, “1s” are transmitted in the signalling bit positions.
ESU 120e User Manual
57
Chapter 5. Configuration Menu
3.
The TS16 multiframe alignment signal must be received
or frame sync.
Note that if CAS/TS16 is enabled, TS16 may not be mapped to a
port and will be forced to “Idle”. When CAS/TS16 is disabled and
TS16 is mapped to a port, the data in TS 16 will be mapped through
from the network to the mapped port. For common channel signalling applications, CAS/TS16 should be disabled and TS16 mapped
to the drop port. TS16 may also be mapped to the base Nx56/64 or
an option module data port.
When CAS/TS16 is enabled, TS16 is forced to idle in TS0
Map A and B and may not be mapped. This configuration
must be used if there are multiple signalling-capable ports
that are mapped to the Network Interface. For applications
where the Base Drop Port requires channel associated signalling (connection to a PBX, for example), CAS/TS16 must be
enabled and TS16 left idle in the TS0 Map.
CRC-4
When this option is enabled, the CRC-4 checksum bits are
transmitted in the outgoing E1 data stream. Also, the
received signal is checked for errors.

ESU 120e Clock Sources
The ESU 120e is operable from various clock sources,
permitting it to perform properly in many different
applications. Set the network interface clocking options
with the clocking options set by the Network (NI)
Configuration menu options.
The following clock source options are available:
•
Network Timed
•
Base Drop Timed
•
Base DTE Timed
•
Internal Timing
•
Normal (CSU) (only when secondary interface module is
installed)
The selected clock option always designates the clock source for
transmission. Clocking necessary for receiving data is always
recovered from incoming data.
Network Timed
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
loop timed as the transmission clock is derived from the received clock. See Figure 5-2.

timings. This timing option is the same as that typically used
for CSUs. This is the preferred mode for use with a PBX application.
This timing mode works equally well when the PBX is the

Set Passcode
Enter Passcode from Other Menus
The PASSCODE prompt may make an unexpected appearance
from other menu operations. This happens only when the
unit is operating in the limited access mode, such as without
an active passcode. The limited access mode may become
active even if a passcode was entered (for example, when
there is no activity for ten minutes). If the unit is to be
remotely accessed using T-Watch PRO, a passcode must be
entered.
When managing a number of units, the passcode can be the same
for all.

Chapter 6. Utility Menu
If the unexpected appearance of the PASSCODE prompt
occurs, for example, while operating in a limited access mode
and attempting to change the DATA RATE, use the following
key sequence: CONFIG > UNIT > CNTROL PORT > DATA RATE.
Use the number keys to enter the correct passcode; then press
Enter. The unit displays ACCESS GRANTED.
Pressing any key after entering a passcode causes the unit to
return to the previous active menu. In this case it returns to
CONFIG > UNIT > CNTROL PORT > DATA RATE to permit
changing the data rate.
Change/Set Passcode
The passcode can be changed or set at any time or eliminated
altogether through the UTILITY menu item SET PASSCODE.
This procedure requires the current passcode (if one is
established) for operation.
The passcode can only be entered by using numbers. After
entering the desired passcode, press Enter.
Set a null passcode at the SET PASSCODE menu by pressing
Enter without any numbers. This sets a null passcode and
grants unlimited access.
Automatic Time-out Feature
For added security protection the unit is equipped with an
automatic time-out for operation with the password. After
ten minutes of inactivity, the unit reverts to limited access
operation. To make changes in the configuration, the passcode can be reentered. If the passcode number is lost, contact
ADTRAN Customer Service for assistance.
No Passcode Desired
At the NEW PASSCODE prompt (in the SET PASSCODE menu),
press Enter without any numerical entry. The system nullifies
the need to enter a password for subsequent use and
proceeds to the UNIT ID prompt.

Loopback Tests
A number of different loopbacks can be invoked locally from
the front panel, by T-Watch commands, or remotely by using
special in-band codes (AT&T D4 network loop-up and loopdown codes). Additionally, the loopbacks can be remotely
controlled by means of out-of-band commands by the E1 ESF
FDL or from T-Watch PRO via a modem connection.
Network Interface Loopbacks
Network interface loopbacks affect the entire E1 data stream
(see Figure 7-2). The two types of network loopbacks are
described below.
Line Loopback
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
Payload loopback is similar to line loopback, except that the
framing is extracted from the received data and then regenerated for the transmitted data.

LOCAL LOOPBCK
There are four choices available for setting the local loopback:
Line On
Activates the line loopback on all TS0s.
FE1 Loopback
Activates a line loopback on all TS0s mapped to TST in the
active map.
Payload On
Activates the payload loopback.
No Loopback
Deactivates the loopback.
Scroll to select a setting; then press Enter. The unit displays
LOCAL LOOPBCK and REMOTE LOOPBCK.
REMOTE LOOPBCK
FE1 Loopback sends V.54 loopback code in all mapped TS0s
toward the network. Far end will respond by initiating a local
line loopback.
TEST PATTERN
All Ones
Sends an all ones pattern to the network.
All Zeros
Sends an all zeros pattern to the network.
QRSS Pattern
The QRSS pattern is commonly used to simulate real data in
E1 interfaces. This pattern can be assigned to appear in all
TS0s or only in TST TS0s. When QRSS is set in all TS0s and
one of the network loopbacks previously described is activated at the far end, a total end-to-end integrity check can be
run without the need for any external test equipment. When
QRSS is assigned to TST TS0s, an integrity check of the link
can be run along with normal data flow. The TST TS0s are
user-assigned as part of the TS0 Map.

This sets the pattern for the test and initiates the transmission
of the pattern. The test is terminated by selecting NONE. The
following patterns are available:
QRSS All TS0s
Generates a QRSS test pattern and inserts the pattern into all
TS0s.
QRSS TST TS0s
Inserts a QRSS pattern in those TS0s mapped as TST in the
currently active map (A or B).
None
Terminates pattern generation.
QRSS always runs at 64K/TS0.
For example, use the up and down arrows to select QRSS
ALL TS0S. Press Enter to record the selection. The ESU 120e
starts to generate a QRSS test pattern and inserts the pattern
into all TS0s. To end the test, select NONE.
PATTERN RESULT
Displays the results of the test currently active. You can leave
and return to this menu item without interrupting the test.
Pressing 2 injects errors into the test pattern. These errors are
detected by the device performing the pattern check.
ES
The number of seconds with at least 1 bit error.
BES
The number of seconds with more than 1 bit error and less
than 320.
SES
The number of seconds with more than 320 bit errors.

Using TST TS0s for testing can be very useful, particularly in
fractional E1 applications. You can run an end-to-end test on
the Fractional TS0s by:
1.
setting for Map B the TST in the same TS0 as used by
Map A to receive data from an Nx56/64 port, and
2.
looping the far end using a V.54 loopback code on the
Nx56/64 port.
In addition, a single TS0 can be used for continuous testing
while other TS0s are passing normal data. This will also
provide an end-to-end check on the entire link. Set each end
to send QRSS in TST TS0s (using 1 TS0) and occasionally
view the results on the PATTERN RESULT menu selection.
Run Self-Test
The self-test checks the integrity of the electronic
components’ internal operation 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 be run with the
network and DTE interfaces in place and will not disturb any
external interface.
The memory portion of the self-test automatically executes
upon power-up. A full self-test can be commanded from a
front panel menu or from T-Watch PRO.
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.

This menu selection is used to execute a full internal self-test.
The results of the self-tests are displayed in the LCD. Upon
invoking the command, the LCD displays SYSTEM SELF-TEST
and the TEST LEDs are illuminated. Test failures are
displayed in the LCD window.
The self-test consists of the following tests:
Board level tests
Each of the ESU 120e boards contains an on-board processor
which executes the following series of tests checking the circuitry on the board:
•
RAM tests; EPROM checksum.
•
TS0 map tests.
•
On-board data path (sending a known test pattern
through an on-board loop).
Unit level tests
• Front panel LED verification.
•
Phase-Lock Loop verify.
•
Board-to-board interface test.
A test pattern is sent from the controller through a loopback
on all other boards and is checked on the controller. This
verifies the data path, clocks, and control signals.
If a failure is detected, note the failure number prior to
contacting ADTRAN Technical Support.
The execution of self-test will disrupt normal data flow and
prevent remote communication until the self-test is
completed.
Port Tests
The PORT TESTS menu is used to activate testing of specific
data ports. It controls the activation of loopbacks and the
initiation of data test patterns. Test results are displayed in

0.1 Nx56/64 is the base Nx interface. It offers the following
test functions.
LOOPBK
This initiates a loopback. The following options are available:
PRT/LCL
The Nx port activates both a Local loopback (back toward the
DTE) and a Port loopback when either is invoked.
REMOTE
The remote loopback causes a V.54 code to be sent to the far
end. The Nx at the far end activates a PRT/LCL loopback
upon detection of the V.54 code.
OFF
The loop is deactivated.

Appendix A
SNMP
As local area network (LAN) environments became
standardized over the past ten years, multi-vendor
equipment grew with competition. It became necessary to
manage the various vendor equipment from a single control
console. Thus, the Simple Network Management Protocol
(SNMP) emerged as the standard for managing commercial
TCP/IP networks.
The term SNMP broadly refers to the message protocols used
to exchange information between the network and the
managed devices, as well as to the structure of network
management databases.
SNMP BASIC COMPONENTS
SNMP has three basic components: Network Manager,
Agent, and MIB.
Network Manager
This is a control program that collects, controls, and presents
data pertinent to the operation of the network devices. It
resides on a network management station.
Agent
This is a control program that responds to queries and
commands from the network manager and returns requested
information or invokes configuration changes initiated by the
manager. It resides in each network device.
MIB
This is an index to the organized data within a network
device. It defines the operating parameters that can be
controlled or monitored. When requesting the network
manager to retrieve or modify a particular piece of
61200420L1-1B
ESU 120e User Manual
95
Appendix A. SNMP
information about a network device, the network manager
transmits the request to that network device. The agent in
that device interprets the incoming request, performs the
requested task, and sends its response to the network
manager. The network manager collects all the data from the
various network devices and presents it in a consistent form.
COMMANDS
Using SNMP Version 1, the network manager can issue three
types of commands: GetRequest, GetNextRequest, and
SetRequest.
GetRequest
This command retrieves a single item or the first in a series
from a network device.
GetNextRequest
This command retrieves the next item in a series from a
network device.
SetRequest
This command writes information to a network device.
MESSAGES
The network device issues two types of messages:
GetResponse and Trap.
GetResponse
This message is the response to a network manager
GetRequest or GetNextRequest command.
Trap
This is an unsolicited message issued by a network device to
report an operational anomaly or an alarm condition to the
network manager.
These messages are typically encased within informational
packets and transported over the LAN or WAN (wide area
network).

The ESU 120e comes configured with community names
(Read - public and Read/Write - public) for SNMP MIB
Browser access to the unit. The ESU 120e can also act as an
SNMP proxy agent for external units. To access MIB variables
on externally chained devices, append a period and the Unit
ID of the device to the Read and Read/Write community
names. For example, if the Read community name
configured in the ESU 120e is public, specifying public.3 as
the community name in the SNMP MIB Browser allows
reading SNMP MIB variables from an externally chained unit
with a Unit ID of 3.
SNMP TRAP CONFIGURATION
Traps received by the ESU 120e from external units and the
host unit are converted into SNMP traps and forwarded to
the configured NMS. The source of the trap is uniquely
identified at the NMS by a combination of the IP address of
the ESU 120e and the Unit ID of the sending device. The Unit
ID is present in the trap packet appended to the end of the
trap community packet name, for example public.4. It is also
included as an Octet String variable (adProdPhysAddress) in
the trap packet as defined in the individual product MIBs.
The latest versions of the product MIBs, by default, display
the appended trap community name in their descriptions.
Typical steps required for Management Station trap
configuration are loading the device specific MIBs and
loading or creating device-specific Trap Definition Files. The
current product MIBs contain keywords embedded in
comments that can be used by some network management
platforms to automatically generate Trap Definitions.
Otherwise, the descriptions may be used as a template for
Trap Definitions.
If individual option card port and slot identification is
required, it is present in the four- byte adProdPhysAddress
field of the trap packet. The first two bytes are the Unit ID of
the base controller (least significant byte first). The next two
61200420L1-1B
ESU 120e User Manual
97
Appendix A. SNMP
bytes are port and slot number. This field is the second object
identifier in all traps sent from ESU/TDU products. For traps
from the ISU 512, the Unit ID is the first object identifier. See
the product MIBs for more information.
Definitions for Poll Link Up/Down traps are included in the
ESU 120e MIB file: ESU 120e.MIB.
SNMP MIB BROWSER CONFIGURATION
The following steps are required to configure Network
Manager MIB variable access through the ESU 120e:
98
1.
Load the desired product MIBs on the network
management station. If, for example, the administrator is
managing ESU 120e and ISU 512 devices, load ESU
120e.MIB, ISU512.MIB, and RFC1406.MIB.
2.
Create device entries in the NMS database for all units
that are to be managed through the ESU 120e. The host
unit should be configured as the Proxy agent for the
external units. The IP address or host name used for the
proxy designation is that of the ESU 120e.
3.
Set community names in the device’s entries for external
units to the ESU 120e community name with the device
Unit ID appended as defined in the previous section
(ESU 120e SNMP Access on page 97).
4.
Set the device timeout for all device entries in the NMS
device database to five seconds, including the host unit.

SNMP MIB FILES
The ESU 120e supports several standard MIBs including the
following:
•
MIB-II (RFC-1213)
•
DS1 E1/E1 MIB (RFC-1406)
•
Ethernet MIB (RFC-1643)
It also supports several ADTRAN enterprise-specific MIBs
including the following:
•
ADTRAN Product MIB (ADTRAN.MIB)
•
ADTRAN DS1 extensions MIB (ADS1.MIB)
•
ESU/TDU Enterprise MIBs, such as ESU 120e.MIB
The standard MIB files are usually included with SNMP
network management software. The latest versions of the
ADTRAN enterprise-specific MIBs are available from the
ADTRAN anonymous ftp site (ftp.adtran.com).
The MIB files are also located on the ADTRAN website at
http://www.adtran.com.
