Abstract
Abstract A high density frame relay circuit within a digital cross-connect matrix converts TDM based DCS matrix data containing frame relay data to/from a DS3 ATM physical interface and provides adaption processing between the frame relay and ATM domains. The circuit is controlled by a DCS administrative subsystem and a simple network management protocol based network element manager.
