Description

Loop Telecom's OCU DP plug-card is an interface card designed for the Loop-V 4200 series multiplexer. When used within the Loop-V 4200, this card combines the OCU DP function with a CSU/DSU.

The Loop OCU DP card is designed to provide full OCU DP operation for office applications and can be used to extend 64K DDS, switched 56K or Frame Relay circuits up to 18,000 feet from the multiplexer.

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 OCU DP module can extend 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 Loop-V 4200 series multiplexer family allows multiple OCU DP module operation with any of the existing interface modules for voice, data or routing.
