FULL FEATURED T1/FT1 DSU/CSU

The ADTRAN TSU LT is a low cost, full-featured T1/FT1 Data Service/ Channel Service Unit (DSU/CSU). The TSU LT 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 LT 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 LT 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 LT provides the capability to control a remote TSU LT through the T1 FDL channel. If the FDL channel is unavailable, the TSU LT 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 LT.

The TSU LT 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. For additional configuration and monitoring options, the TSU LT supports a VT100 terminal configuration and control mode which is available through the control port. For direct serial connections or for remote devices, optional Windows(R) based PC Management is available through the comprehensive, easy to use T-Watch PRO(TM) software package.

ADTRAN provides several T1 DSU/CSUs for a variety of customer applications. Additional products in the TSU family include the TSU, 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.
