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.

Introduction  
Chapter 1  
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.

Chapter 2. Installation  
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  
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.  
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 6-2 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 6-4 for details.

Chapter 2. Installation  
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.

status and performance data as the front panel LCD. This data is  
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.

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.

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.  
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 net-  
work 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 in-  
stalled)  
The selected clock option always designates the clock source for  
transmission. Clocking necessary for receiving data is always re-  
covered from incoming data.

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.

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 loop-down 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 (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  
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.

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

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.

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.
