About this Manual
This manual provides a complete description of the TSU LT system and system software. The purpose of
this manual is to provide the technician, system administrator, and manager with general and specific
information related to the planning, installation, operation, and maintenance of the TSU LT. This manual is
arranged so that needed information can be quickly and easily found.
When using your telephone equipment, please follow these basic safety precautions to reduce the risk of
fire, electrical shock, or personal injury:
1. Do not use this product near water, such as a bathtub, wash bowl, kitchen sink, laundry tub, in a
wet basement, or near a swimming pool.
2. Avoid using a telephone (other than a cordless-type) during an electrical storm. There is a remote
risk of shock from lightning.
3. Do not use the telephone to report a gas leak in the vicinity of the leak.
4. Use only the power cord, power supply, and/or batteries indicated in the manual. Do not dispose of
batteries in a fire. They may explode. Check with local codes for special disposal instructions.
5. The socket-outlet shall be installed near the equipment and shall be easily accessible.
Product:TSU LT
Model Numbers:1203060L1
FCC Registration Number: US: HDCDENAN1203060L1
FCC regulations require that the following information be provided to the customer:
1. This equipment complies with Part 68 of the FCC rules. On the side or bottom of this equipment is
a label that contains, among other information, the FCC Registration Number and Ringer
Equivalence Number (REN), if applicable, for this equipment. If required, this information must
be given to the telephone company.
2. An FCC-compliant telephone cord and modular plug is provided with this equipment. This
equipment is designed to be connected to the telephone network or premises wiring using a
compatible modular jack which is Part 68-compliant. See installation instructions for details.
3. If your telephone equipment causes harm to the telephone network, the telephone company may
discontinue your service temporarily. If possible, they will notify you in advance. But if advance
notice isn’t practical, you will be notified as soon as possible. You will be advised of your right to
file a complaint with the FCC.
4. Your telephone company may make changes in its facilities, equipment, operations, or procedures
that could affect the proper operation of your equipment. If they do, you will be given advance
notice to give you an opportunity to maintain uninterrupted service.
5. If you experience trouble with this equipment, please contact ADTRAN at (256) 963-8722 for
repair/warranty information. The telephone company may ask you to disconnect this equipment
from the network until the problem has been corrected or until you are sure the equipment is not
malfunctioning.
6. This unit contains no user-serviceable parts.
7. The FCC recommends that the AC outlet to which equipment requiring AC power is to be installed
is provided with an AC surge arrester.
8. The REN is used to determine the quantity of devices which may be connected to the telephone
line. Excessive RENs on the telephone line may result in the devices not ringing in response to an
incoming call. In most, but not all areas, the sum of RENs should not exceed five (5.0). To be
certain of the number of devices that may be connected to a line, as determined by the total RENs,
contact the local telephone company.
9. The following information may be required when applying to your local telephone company for
leased line facilities.
Federal Communications Commission Radio Frequency Interference StatementTSU LT User Manual
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.
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 for filing an affidavit with the local exchange carrier when
connecting unprotected customer premise equipment (CPE) to 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.

The TSU LT belongs to the ADTRAN T1 single-port CSU/DSU family offering complete flexibility in
connecting various data sources to T1 or FT1 facilities (see Table 1-1).
Table 1-1. TSU Family of Single-port CSU/DSUs
ProductDescription
TSU ACET1 CSU/DSU with a single Nx56/64K serial port that offers front panel configuration only.
TSU LTT1 CSU/DSU with a single Nx56/64K serial port that offers terminal, front panel, or T-Watch PRO
configuration options.
The TSU LT serves as the link between user data sources such as local area network (LAN) bridges and
routers, computers, CAD systems, and teleconferencing equipment. The amount of bandwidth allocated to
the port is custom programmable. The data terminal equipment (DTE) data can occupy contiguous or
alternate channels in the T1 stream, and the channels may start at any position.
TSU LT Physical Description
Figure 1-1 shows the TSU LT front panel and Figure 1-2 shows the rear panel.
•Easy configuration capabilities using simplistic menus displayed in a liquid crystal display (LCD)
window operated by a front panel keypad.
•Timing is selectable from the network, from the Nx56/64 DTE port, or internally.
•Variety of test patterns: all ones, all zeros, 511, 1:8.
•Extensive self-testing and monitoring ensures proper operation.
•Flexible channel allocation (any starting channel and alternate or contiguous).
TSU LT Interfaces
The TSU LT is equipped with four interfaces:
•Network DS1 interface per AT&T 62411
•Nx56/64 serial V.35
•Control input (EIA-232)/Chain port input
•Chain port output
TSU LT BRIDGE/ROUTER APPLICATION
A bridge or router can be interfaced to the network by using the V.35 DTE interface. The bandwidth used
is programmable at Nx56 or Nx64 data rates for T1 or FT1 service. The bandwidth can be selected as
contiguous or alternate. Figure 1-3 shows a simple bridge application.
