INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to Part 15 of the FCC Rules. These lim-
its are designed to provide reasonable protection against harmful inter-
ference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio frequencies. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.
Shielded cables must be used with this unit to ensure compliance with
Class A FCC limits.
Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user’s authority to op-
erate the equipment.

CANADIAN EQUIPMENT LIMITATIONS
The Industry Canada Certification label identifies certified equipment.
This certification means that the equipment meets certain telecommu-
nications 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 permissi-
ble to be connected to the facilities of the local telecommunications com-
pany. 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 cer-
tified 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 Cana-
dian maintenance facility designated by the supplier. Any repairs or al-
terations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to re-
quest 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 con-
tact the appropriate electric inspection authority, or an electrician, as appropri-
ate.
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.
The ringer equivalence number (REN) assigned to each terminal adapter
is used to determine the total number of devices that may be connected
to each circuit. The sum of the RENs from all devices in the circuit
should not exceed a total of 5.0.

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 man-
agement. 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 a E1 circuit. The amount of band-
width 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 provides a path
for growth to accommodate future requirements.
The ESU 120e offers a wide variety of network management
options. You can manage via SNMP through the 10BaseT or chain-
in ports. If you are using T-Watch Pro, a Microsoft Windows® pro-
gram, you can manage the ESU 120e via the same 10BaseT or chain-
in ports. An enhanced VT-100 terminal interface is also provided.

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 selec-
tion 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 Menu on page 5-11 for details.
Unless locked out externally, the front panel can also control the
unit.
Chain In/ Chain Out
ESU 120e units and other ESUs can be linked together to form a
chain. Figure 2-4 shows an example of a chain-in arrangement with
a PC or a modem. The first ESU 120e in the chain receives control-
ling input from the PC or modem.

Subsequent ESUs in the chain are in a position to intake informa-
tion 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 nec-
essary 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 subse-
quent power-up sequences.
NORMAL POWER-UP PROCED URE
After the unit has been put into operation with the initial power-up
and initialization, subsequent power-up procedure includes only
the Power-Up self-test followed by the request for a passcode
(password) if this option was selected during initialization.
Use the number keys to enter the previously recorded passcode fol-
lowed by pressing Enter.

D ata Port Identification
When configuring the unit, menu selections will include options
from data port submenus. Selecting of data ports is necessary
because the ESU 120e uses a Slot-Port method to identify which
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.
Front Panel Menu Structure
The ESU 120e uses a multilevel menu structure containing both
menu items and data fields. All menu operations and data display
in the LCD window.
The opening menu is the access point to all other operations. Each
Main menu item has several functions and submenus to identify
and access specific parameters.

displayed in the form of tables and graphs.
The T-Watch PRO program has the following capabilities:
•
Interfaces with a modem which permits dialing into a remote
ESU 120e location to configure the unit or read the status or per-
formance of the unit.
•
•
Receives traps from any ESU product.

Description
• 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 ap-
plications, 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 DS0
Map A and B and may not be mapped. This configura-
tion must be used if there are multiple signalling-capable
ports that are mapped to the Network Interface. For ap-
plications where the Base Drop Port requires channel as-
sociated signalling, (connection to a PBX, for example)
CAS/TS16 must be enabled and TS16 left idle in the DS0
Map.

When this option is enabled, the CRC-4 checksum bits are

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

Normal (CSU) Timing
The typical timing option arrangement is shown in Figure 5-6. The
PBX is looped timed sending data to the ESU 120e which is actually
synchronous to the received data. The Network Interface (NI) is
the actual source of all 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 source of
timing. In that configuration the network would not be providing
timing.

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 (see Figure 7-2 on page 7-3) affect the
entire E1 data stream. There are two types of network loopbacks,
line loopback and payload loopback.
Line loopback loops all of the received data back toward the net-
work. The transmitted data is the identical line code that was
received, including any bipolar violations or framing errors.
Payload loopback is similar to line loopback, except that the fram-
ing is extracted from the received data and then regenerated for the
transmitted data.

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 net-
work 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

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.

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.
*SYNC Indicates if pattern sync is (yes) or is not (no) valid. The
asterisk (*) indicates if pattern sync has been lost since
the start of testing.
Clear results by pressing shift 9. The results are accumulated until
the test pattern is set to None or Cleared.
Using TST TS0s for testing can be very useful, particularly in Frac-
tional E1 applications. You can run an end-to-end test on the Frac-
tional 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) by 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 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 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 also run
on various parts of the internal electronics. These run during nor-
mal 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:
Test Name What it does . . .
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 pat-
tern 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 the LCD window.
The execution of Port Tests will disrupt normal data flow in the
port being tested.

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.
The ESU 120e checks the remote loopback activation by detecting
a proper response from the remote end. While waiting for the re-
sponse, the display shows Looping. If successful, the display
changes to Looped -Up. If unsuccessful, the display shows Failed.

You can use the Up and Down arrows or number keys to move the
cursor from one selection to another. Use the Enter key to perform
the action displayed in the LCD to the right of the cursor.
Normally, map configuration involves these steps. The first step is
optional and consists of initializing the Temp map to one of three
configurations (current Map A, current Map B, or all IDLES). Step 2
involves editing the Temp map so that it reflects the desired map
configuration. Finally, step 3 replaces the current TS0 map A or B
configuration with the Temp map configuration.
Initializing the Temp Map
Upon entering the TS0 maps configuration menu, the Temp map
reflects its last configured state. You can then use selections 1
through 3 to initialize the displayed Temp map to one of three con-
figurations. You can use selections 1 and 2 to initialize the Temp
map from its current configuration to one which reflects the cur-
rently stored Map A or B configurations, respectively. Selection 3
initializes the Temp map to an all IDLE state.
Editing the Temp Map
If further changes to the Temp map are needed, use selection 7 to
enter the Temp map edit mode. Upon entering this mode, the cur-
sor location moves to TS0 number one in the TS0 field of the Temp
map. The cursor may be moved from one TS0 to another using the
Up and Down arrows until it is located at the TS0 number whose
assigned port needs to be changed. At this point, pressing the Enter
key causes the cursor to move into the Port field. The Up and Down
arrows are then used to allow scrolling through the possible port
selections. To restore the previous port assignment and return to
the TS0 field, you may press the ESC key. Otherwise, press the
Enter key to save the current selected port and return to the TS0
field. Once the cursor is again located in the Temp map TS0 field,
pressing the ESC key a second time, causes the cursor to return to
selection 1 below the Temp map display.
Applying the Temp Map
Once the Temp map reflects the desired configuration, use selec-
tions 8 or 9 to apply this configuration to Map A or B, respectively.
Reviewing Temp Maps
Selections 4 through 6 give a summary of the number of ports
assigned to Map A, Map B, and the Temp map, respectively.

SNMP Read Community Name defaults to public. NMSs using
this community name have Read access for all supported MIB
objects but do not have the ability to change MIB objects. This
value must be set to the same value on both the ESU 120e and the
NMS (OpenView®, etc.) in order for the NMS to have Read access
to MIBs supported by the ESU 120e. This value must be a text
string of 16 characters or less.
SNMP Read/ Write Community
SNMP NMS using this community name have full read/write
access to all supported MIB objects (defaults to private). This set-
ting must be the same value on both the ESU 120e and the NMS in
order for the NMS to have read/write access to MIBS supported by
the ESU 120e. This value must be a text string that is 16 characters
or less.
To access other units external to the ESU 120e (proxied units) us-
ing an SNMP MIB browser, append a period and the unit ID of
the external device to the Read Only and Read/Write community
name used in the MIB Browser, for example public.4. See the Ap-

Understanding SNMP
A ppendix A
As local area network (LAN) environments became standardized
over the past ten years, multi-vendor equipment grew with compe-
tition. It became necessary to manage the various vendor equip-
ment from a single control console. Thus, the 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 data-
bases.
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.
1200420L1-1
ESU 120e User Manual
A-1
Appendix A. Understanding SNMP
MIB
This is an index to the organized data within a network device. It
defines the operating parameters that can be controlled or moni-
tored. When requesting the network manager to retrieve or modify
a particular piece of information about a network device, the net-
work 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 net-
work devices and presents it in a consistent form.
COMMAND S
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.
A-2
ESU 120e User Manual
1200420L1-1
Appendix A. Understanding SNMP
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 man-
ager.
These messages are typically encased within informational packets
and transported over the LAN or WAN (wide area network).
ESU 120E SNMP ACCESS
By default, SNMP MIB Browser access to the ESU 120e IP address
with the configured community names, accesses the host. 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 externally chained unit 3.
If the external unit's passcode is not the default, an entry must be
added to the Unit Access Table for SNMP MIB access. See the Unit
Access Table section in Chapter 3: Operation for more information.
However, SNMP traps for the unit can be forwarded without the
entry.
1200420L1-1
ESU 120e User Manual
A-3
Appendix A. Understanding SNMP
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 config-
ured 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 exam-
ple public.4. It is also included as an Octet String variable (adProd-
PhysAddress) 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 net-
work management platforms to automatically generate Trap Defi-
nitions. 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 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 informa-
tion
Definitions for Poll Link Up/Down traps are included in the ESU
120e MIB file: ESU 120e.MIB.

ESU 120e User Manual
1200420L1-1
Appendix A. Understanding SNMP
SNMP MIB BROWSER CONFIGURATION
The following steps are required to configure Network Manager
MIB variable access through the ESU 120e:
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.
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 MIB-II
(RFC-1213), the DS1 E1/E1 MIB (RFC-1406), and the Ethernet MIB
(RFC-1643). It also supports several ADTRAN enterprise-specific
MIBs including the ADTRAN Product MIB (ADTRAN.MIB), the
ADTRAN DS1 extensions MIB (ADS1.MIB), and all ESU/TDU
Enterprise MIBs, such as ESU 120e.MIB.
The standard MIB files are usually included with most SNMP net-
work management software. The latest version of the ADTRAN
enterprise specific MIBs are available from the ADTRAN anony-
mous ftp site (ftp.adtran.com), or by dial-up from the BBS (205 -
971-8169). The MIB files are also located on the ADTRAN WWW
site at http://www.adtran.com.
