Adtran 1200062L1 CSU/DSU 56/64

CSU/DSU 56/64

The Adtran DSU 56/64 provides a cost-effective solution for termination of 56 or 64kbps DDS services. This DSU is a very economical solution for single port point-to-point, multi-point or frame relay applications. Extensive use of VLSI technology provides a highly reliable feature-rich DSU, and the enclosure for the DSU 56/64 is a small, attractive, slim-line package that is wall mountable, rack mountable or can sit on a desktop. The DSU 56/64 provides both a physical and electrical V.35 DTE interface, which is mounted on the rear panel. The DTE interface operates at the same rate as the network, either 56 or 64kbps. Also located on the rear panel is a set of option DIP switches along with an RJ-48S network interface. The option switches allows you to select the Network/DTE data rate, control lead options, remote digital loopback, and scrambler options. It responds to standard loopback commands from the service provider, and has built-in test capabilities which include V.54 remote loopback, DTE, DTE and loop, DTE with test pattern, and loop only. Included with the remote loopback is the capability to select a 2047 BERT test pattern, with results displayed on the front panel. The front panel of the DSU 56/64 provides a set of eleven LED indicators. Five of the indicators show the status of the V.35 DTE or EIA-232 interface while the remaining LEDs indicate the various test modes and loop status. Two front panel keys allow you to select one of the several test modes the unit supports.
