ADTRAN 1200230L1 OCU DP DUAL EXPANSION MODULE 4 PORT

The ADTRAN Dual OCU DP Module is an expansion module for the TSU Multiplexer family. Designed to provide full OCU DP operation for office applications, the module can be used to extend 64k DDS, Switched 56 or Frame Relay circuits up to 18, 000 feet from the multiplexer. The Dual OCU DP expansion module and the Dual OCU DP Plug-On module now expand the capacity of the TSU multiplexer family to support four OCU DP interfaces per expansion slot. For CPE applications, the Dual OCU DP module allows network administrators to cut network access charges and continue to support traditional DDS/SW56 requirements. By re-using existing CPE products such as the DSU III AR, the Dual OCU DP module can extend two switched 56 circuits to a conference room to support video-conferencing. The module can also be used to extend a 56k Frame Relay circuit to FSU located in a computer room. The flexibility of the TSU Multiplexer family allows Dual OCU DP operation with any of the existing modules for voice, data or routing.
