TSU ACE is a low cost, full-featured T1/FT1 Data
Service/ Channel Service Unit (DSU/CSU). The TSU ACE 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 video-conferencing. The TSU ACE
provides access to traditional dedicated point-to-point T1 services as well
as network termination for Frame Relay.
Housed in a compact, durable plastic housing the TSU ACE 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 ACE provides the capability for
remote control from a host TSU through the T1 FDL channel. If the FDL
channel is unavailable, the host TSU can use 8 kbps of the data traffic to
provide configuration and control of the remote TSU ACE. The in-band
control channel is used on an as needed basis and is automatically controlled
by the host TSU.
The TSU ACE responds to standard local and remote loopback commands
from the telephone 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.
ADTRAN provides several T1 DSU/CSUs for a variety of customer
applications. Additional products in the TSU family include the TSU LT,
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.
