Compare Adtran DSU III AR (1200128L1) to Adtran DSU 5600 (1200078L1)

The ADTRAN Dual DSU III Module is one of several expansion modules for the TSU multiplexer family of products. This module should be selected when the customer's data terminal equipment (DTE) needs to be connected to the Digital Data Service (DDS) or the Switched 56 network using a T1 line. The module installs in the expansion slot of the TSU and is subject to the unit's operation and control. A plug-on version of the Dual DSU III is also available for any of the other TSU expansion modules. Both the expansion module and the plug-on module provide two DTE interfaces each. The expansion module accepts other Plug-on modules, the plug-on module works with any expansion module. ??Configuration is available from the front panel of the TSU or by the optional T-Watch PRO management software. Monitoring, performance requests, and testing functions are initiated from the front panel. Each unit provides two separate all rate DSUs supporting synchronous and asynchronous data rates.

The ADTRAN DSU 5600 provides cost-effective solutions for termination of 56 kbps DDS services. The unit 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. The enclosure for DSU 5600 is a small, attractive, slim-line package that is wall mountable, rack mountable or can sit on a desktop. ??The DSU 5600 provides both a physical and electrical EIA-232 DTE interface, which is mounted on the rear panel. The network interface operates at either 56 or 64 kbps. The DTE interface operates either at 56 or 64 kbps synchronous or 1.2 to 57.6 kbps asynchronous. Also located on the rear panel are option switches along with an RJ-48S network interface. The option switches allow the user to select the rate of operation, control lead options, remote digital loopback, and scrambler options. Less
