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 videoconferencing. 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 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.
The TSU responds to standard local and
remote loopback commands from the telephone company central office. In addition,
