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.

sur le materiel brouilleur: “Appareils Numeriques,” NMB-003 edictee
par le ministre des Communications.
vi
CANADIAN EQUIPMENT LIMITATIONS
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.
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.
vii
AFFIDAVIT REQUIREMENTS FOR CONNECTION
TO DIGITAL SERVICES
• An affidavit is required to be given to the telephone company whenever 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 to file an affidavit with the
local exchange carrier when connecting unprotected CPE to a 1.544
Mbps or subrate digital services.
• Until such time as subrate digital terminal equipment is registered
for voice applications, the affidavit requirement for subrate services
is waived.

TSU 100 OVERVIEW
This manual covers the use of the following products:
• TSU 100
• TSU 100e
Unless otherwise stated, the TSU 100 refers to both products.
The TSU 100 is a T1/FT1 multiplexer with an Nx56/64 V.35
data port, one option slot and embedded SNMP management.
The TSU 100e also offers a built-in dial back-up feature for the
Nx port. The TSU 100’s option slot accepts one of many available option modules for voice and data applications.
The TSU 100 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 TSU 100 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.
Introduction
61202052L1-1 TSU 100 User Manual 1-1

• An inband communication channel requiring only 8k of
bandwidth from a single DS0
• One option slot to house option modules with up to four additional ports, including voice and data
• Allows mix of port types to meet the data interface requirements
• Easy configuration capabilities using simplistic menus displayed in a liquid crystal display (LCD) window operated
by a front panel keypad
• Two programmable configuration maps that define the
bandwidth allocation between data ports
• Flash memory for software updates
• Selectable timing from the network, from the Nx56/64 port,
internally, or from a secondary interface
• SNMP, Telnet, and T-WATCH Pro management via SLIP or
10BaseT (TSU 100e only)
• Ability to proxy for agentless units
• Enhanced terminal mode
• QRSS; 511 test patterns using Nx option
• Fractional T1 loopbacks as defined in Annex B of ANSI
T1.403-1995

The control port input provides an EIA-232 input from a PC or
a modem for control of the TSU 100. You can also use it as a
chain input from another TSU 100e or the TSU 100. For more
information see Appendix C, Wiring on page C-1.

The 10BaseT interface provides the LAN interface for managing the TSU 100 with SNMP or T-WATCH Pro. For more information see Appendix C, Wiring on page C-1.
Power Up Testing
When shipped from the factory, the TSU 100 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 passcode and Unit ID may be
set using the UTIL Menu.

Initialization
Set User Passcode
Set Unit Identification
Chapter 2. Installation
The TSU 100 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 6-3 for details.
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 Menu on page 6-5 for details.
Set Chain Port
The TSU 100 can be configured from the chain-in port when
either T-WATCH Pro, SNMP, or the terminal interface is being
used. If the chain-in port is to be used, the chain-in 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 5-11 for
details.
Unless locked out externally, the front panel can also control
the unit.

Chain-In/Chain-Out
TSU 100 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 100 in the chain
receives controlling input from the PC or modem.

Subsequent TSUs in the chain are in a position to intake information from another TSU. This in-taking of information from
another TSU 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 ensures that they are operable for subsequent power-up sequences.

Alternate Methods of Control
T-WATCH Pro (ADTRAN PC Program)
T-WATCH Pro is the ADTRAN PC control program. It provides
complete control over the configuration of the TSU 100 using a
graphical interface. The T-WATCH Pro program displays the
same 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 TSU 100 location to configure the unit or read the status or performance of the unit.
• Receives traps from any TSU product.
• Records and creates display performance data over a 30 day
period.
• Accesses units via the local area network (TSU 100e only).

TSU 100 Clock Sources
The TSU 100 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
• DTE Timing
• Internal Timing
•Secondary Timing
•Normal (CSU)
•U-BR1TE
The selected clock option always designates the clock source for
transmission. Clocking necessary for receiving data is always recovered from incoming data.

Chapter 5. Configuration Menu
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.
5-6
Figure 5-2. Network Timed Clock Source
TSU 100 User Manual 61202052L1-1
DTE Timed
The DTE is the source of timing. The TSU 100 uses the incoming DTE clock to determine the transmission timing. This is
typically used in applications where it is necessary to have the
DTE as the primary clock source (such as limited distance line
drivers). See Figure 5-3.

The TSU 100 is the source of timing. The TSU 100 is configured
to use its own internal oscillator as the source of timing. Applications include private line driver circuits where one end is set
to network and the other to internal. See Figure 5-4.

Loopback Tests
A number of different loop-backs can be invoked locally from
the front panel, by T-WATCH Pro commands, or remotely by
using special in-band codes (AT&T D4 network loop-up and
loop-down codes). Additionally, the loop-backs 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 loop-backs affect the entire T1 data stream.
See Figure 7-2. There are two types of network loop-backs, line
loop-back and payload loop-back.
Line loop-back
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 loop-back
Chapter 7. Test Menu
Similar to line loop-back, except that the framing is extracted
from the received data and then regenerated for the transmitted data.

Test Patterns
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 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 loop-backs 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.

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. By looping the far end using a V.54 loop-back code on the
Nx/DBU port (DBU is TSU 100e only).

Run SelfTest
Chapter 7. Test Menu
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.
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
