The ADTRAN

TSU

™

is a low cost, full-featured

T1/FT1 Data Service/ Channel Service Unit

(DSU/CSU). The TSU provides an interface

between T1 or Fractional T1 service and the

end user’s Data Terminal Equipment (DTE)

for applications such as LAN to LAN bridging,

Frame Relay circuit termination and videocon-

ferencing. The TSU provides access to traditional

dedicated point-to-point T1 services as well

as network termination for Frame Relay.

Housed in a rugged metal housing the

TSU supports synchronous data rates from

56 kbps to 1.536 Mbps at Nx56 or Nx64 kbps.

A single V.35 physical interface provides a

connection to the end user’s DTE equipment.

For configuration and testing, the TSU

provides the capability to control a remote

TSU through the T1 FDL channel. If the

FDL channel is unavailable, the TSU can

use 8 kbps of the data traffic to provide

configuration and control of the remote

unit. The in-band control channel is used

on an as needed basis and is automatically

controlled by the TSU.

The TSU responds to standard local and

remote loopback commands from the tele-

phone company central office. In addition,

the user has several built-in test capabilities

including V.54 remote loopback and 511 BERT

test patterns. Complete configuration and

performance data is available from the front

panel keypad and two-line by 16 character

LCD display. For additional configuration

and monitoring options, the TSU supports

a VT 100 terminal configuration and control

mode which is available through the control

port. For direct serial connections or for

remote devices, optional Windows

based PC

management is available through the

comprehensive, easy to use T-Watch PRO

™

software package.

ADTRAN provides several T1 DSU/CSUs

for a variety of customer applications.

Additional products in the TSU family include

the TSU ACE, TSU ESP, TSU100, TSU120,

TDU120 and the TSU600. These T1/FT1

DSU/CSUs offer flexibility, modularity and

end user configuration. The modular

approach allows the ADTRAN TSU family

to serve in point-to-point T1 applications

with a mixture of voice, data and video.
