digital terminal equipment without encoded analog content and billing
protection is used to transmit digital signals containing encoded analog
content which are intended for eventual conversion into voiceband analog
signals and transmitted on the network.
The affidavit shall affirm that either no encoded analog content or billing
information is being transmitted or that the output of the device meets Part
68 encoded analog content or billing protection specifications.
End user/customer will be responsible for filing an affidavit with the local
exchange carrier when connecting unprotected customer premise equipment
(CPE) to 1.544 Mbps or subrate digital services.

connect to your telephone line and still have all of those devices ring
when your number is called. In most areas, the sum of the RENs of all
devices should not exceed five. To be certain of the number of devices
you may connect to your line as determined by the REN, call your
telephone company to determine the maximum REN for your calling
area.

Federal Communications Commission Radio Frequency
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 limits are
designed to provide reasonable protection against harmful interference 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 operate the equipment.
Canadian Emissions Requirements
This digital apparatus does not exceed the Class A limits for radio noise
emissions from digital apparatus as set out in the interference-causing
equipment standard entitled “Digital Apparatus,” ICES-003 of the Department
of Communications.
Cet appareil nuerique respecte les limites de bruits radioelectriques applicables
aux appareils numeriques de Class A prescrites dans la norme sur le materiel
brouilleur: “Appareils Numeriques,” NMB-003 edictee par le ministre des
Communications.
x
Canadian Equipment Limitations
Notice: The Canadian Industry and Science Canada 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
limitations 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 water pipe
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 contract 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 requirement that the total of the
Load Numbers of all devices does not exceed 100.

TSU 120 OVERVIEW
This manual covers the use of the following products:
•
TSU 120
•
TSU 120e
Unless otherwise stated, the TSU 120 refers to both products.
The TSU 120 is a T1/FT1 multiplexer with an Nx56/64 V.35
data port, a DSX-1 (PBX) interface, a 10BaseT port, one option
slot, and embedded SNMP management. The TSU 120e offers a
built-in dial back up feature for the Nx port. The TSU 120’s
option slot accepts one of many available option modules for
voice and data applications.
The TSU 120 links 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 TSU 120 can simultaneously connect one or
more of these devices to a T1 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 provides a path for growth to accommodate future requirements.

Power Up Testing
When shipped from the factory, the TSU 120 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. A passcode 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 self-test is completed with no failures detected, the OK LED lights up and the
LCD momentarily displays MEMORY TEST(S) PASSED. If a failure is detected, a list of failures is displayed in the LCD window.
Initialization
Set User Passcode
The TSU 120 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 Change/Set a Passcode on page 6-4 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.

Set Chain Port Input
The TSU 120 can be configured from the chain port input when
T-WATCH Pro, SNMP, or the terminal interface are being used.
In this case, the chain 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 chainin, the selection of the chain-in port baud rate from 9600 (factory default), 1200, 2400, 19200, or 38400 must be made using
the UNIT CONFIGURATION MENU. See Unit Menu on page 5-12 for
details.
Unless locked out externally, the front panel can also control
the unit.
Chain-in/Chain Out
TSU 120 units and other TSUs can be linked together to form a
chain. Figure 2-4 provides an example of a chain-in arrangement with a PC or a modem. The first TSU 120 in the chain
receives controlling input from the PC or modem.

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 ensures they are operable
for subsequent power-up sequences.
Power-Up Procedure
After the unit has been put into operation with the initial
power-up and initialization, the 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 and press Enter.

Data Port Identification
When configuring the unit, menu selections will include
options from data port submenus. Selecting data ports is necessary because the TSU 120 uses a slot-port method to identify
which data port the menu item is referencing. If a module containing a PBX DSX-1 option card with an Nx56/64 plug-on
interface is installed in the option slot, it would be designated
as:
DSX-1 Passthru=1.1
Where slot=1 and port =1.
The DSX-1 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 TSU 120 are referenced as Slot
0. The Nx56/64 would be designated as 0.1 and the DSX-1
would be referenced as 0.2.

IP ADDRESS
Description
This is the IP address that uniquely identifies
the TSU 120 on a TCP/IP network.
This address is composed of four decimal
numbers, each in the range of 0 to 255,
separated by periods. This value is used for
either the 10BaseT Ethernet or SLIP interface,
depending on the IP interface setting
(10BaseT is only available in the TSU 120e).
SUBNET
MASK
This defines which part of a destination IP
address is the Network number. It is used
along with the TSU 120 IP address to
determine which nodes must be reached
through the default IP Gateway. This value is
ignored when the IP interface is set to SLIP.
DEFAULT
ROUTER
All IP Packets destined for nodes not on the
TSU 120 unit’s local network are not

Temp Map area. This permits modification
without disturbing the existing map. When
the modifications are completed, the Temp
Map is written to current MAP A (B) by
selecting Apply.
CREATE TEMP
This creates a map by defining a port or Idle
for all DS0s. When CREATE TEMP is first
selected, all DS0s are set to Idle. See DS0 Map
Example on page 5-16 for more information.

Network Tests
Network tests control the activation of loopbacks and the initiation of data test patterns.
Network tests are run on the Network Interface (NI). You can
select three different test configurations to determine the type
of loopback and the pattern to run. Test results display in the
LCD window.
Executing NETWORK TESTS will disrupt normal data flow
unless only TST DS0S are selected for testing.
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 T1 ESF FDL
or from T-WATCH Pro by a modem connection.
Network Interface Loopbacks
Network interface loopbacks (see Figure 7-2 on page 7-4) affect
the entire T1 data stream. There are two types of network loopbacks, LINE LOOPBACK and PAYLOAD LOOPBACK.
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.

Remote Loopback can only be used with Fractional T1 if the ANSI
FT1 LLB is selected.
After a Remote Loopback option is selected, the TSU 120 verifies that the far end is actually in a loopback by checking for the
receipt of a code looped back from the far end. Once the
Remote Loopback type is selected, the LCD displays the loopback progress by displaying LOOPING until loopback is verified.
Test Patterns
All Zeros
Sends an all zeros pattern to the network.
All Ones
Sends an all ones pattern to the network.
QRSS Pattern
The QRSS pattern is commonly used to simulate real data in T1
interfaces. This pattern can be assigned to appear in all DS0s or
only in TST DS0s. When QRSS is set in all DS0s 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 DS0s, an integrity check of the link can be run along
with normal data flow. The TST DS0s are user-assigned as part
of the DS0 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:

Using TST DS0s for testing can be very useful, particularly in
Fractional T1 applications. You can run an end-to-end test on
the Fractional DS0s by:
1. Setting for Map B the TST in the same DS0 as used by Map
A to receive data from an Nx/DBU port, and
2. Looping the far end using a V.54 loopback code on the Nx/
DBU port (DBU is TSU 120e only).
In addition, a single DS0 can be used for continuous testing
while other DS0s 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 DS0s (using 1 DS0) 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 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 TSU 120 boards contain an
on-board processor which executes a
series of tests checking the circuitry
on the board.
•
UNIT LEVEL TESTS
RAM tests; EPROM checksum
•
DS0 map tests
•
On-board data path; sending a
known test pattern through an onboard loop
•
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 and contact
ADTRAN Technical Support.
Executing the self-test will disrupt normal data flow and prevent
remote communication until it is complete.
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.
Port tests execution will disrupt normal data flow in the port being tested.

Understanding SNMP
ABOUT 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
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.
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.
61202029L1-1
TSU 120 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
monitored. When requesting the network manager to retrieve
or modify a particular piece of 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.
A-2
TSU 120 User Manual
61202029L1-1
Appendix A. Understanding SNMP
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).
TSU 120 SNMP Access
By default, SNMP MIB Browser access to the TSU 120 IP
address with the configured community names, accesses the
host. The TSU 120 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 TSU 120 is public,
specifying public.3 as the community name in the SNMP MIB
Browser allows reading SNMP MIB variables from externally
chained unit with a Unit ID of 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 on page 8-5, for more information. However, SNMP traps for the unit can be forwarded without the
entry.
61202029L1-1
TSU 120 User Manual
A-3
Appendix A. Understanding SNMP
SNMP Trap Configuration
Traps received by the TSU 120 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 TSU 120,
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 bytes
are port and slot number. This field is the second object identifier in all traps sent from TSU/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
TSU 120e MIB file: TSU 120e.MIB.
The TSU 120 and TSU 120e share the same MIB.

2
Create device entries in the NMS database for all units that are to be
managed through the TSU 120. 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 TSU 120.
3
Set community names in the device’s entries for external units to the
TSU 120 community name with the device Unit ID appended as
defined in the previous section TSU 120 SNMP ACCESS on page A-3.

LINE ON is placed in history. The alarms and loopback are cleared when FELP is no longer received.
Loss of Data
The TSU 120 will send MINOR ALARM and the A
SHELF ALARM for 2.5s when it quits receiving the
data link on the T-Span. It will also report TR-08 DL
Down in the history. After 2.5s, MAJOR ALARM, A
SHELF ALARM are sent across the Data Link.
OOF
The TSU will send MINOR ALARM and A SHELF
ALARM upon receiving an out-of-frame condition.
TR-08 DL Down and RED ALARM are declared in
history for severe framing errors. After 2.5s, MAJOR
ALARM, A SHELF ALARM are sent across the Data
Link.
Loss of Signal The TSU 120 will send MINOR ALARM and the A
SHELF ALARM for 2.5s when it quits receiving a
signal from the far end. It will also report TR-08 DL
Down and LOS in the history. After 2.5s, MAJOR
ALARM, A SHELF ALARM are sent across the Data
Link, and RED ALARM is declared in history.
B-2
BPVs
BPVs that are received at a rate greater than the
threshold set under TR-08 options, will cause
MINOR ALARM and A SHELF ALARM to be sent
on the DL. If the BPVs remain above the threshold for
2.5s, the TSU 120 will send MAJOR ALARM on the
DL. No events are placed in history.
Protection
Line Switch
The TSU will not respond to this alarm.
