ABSTRACT:
A control system for a network element (NE) such as a remote digital terminal (RDT) in an integrated digital loop carrier (DLC) system is provided which comprises subsystems for operating circuit packs and for providing functions that are common to the circuit packs. Each subsystem has a subagent residing on a network processor circuit pack. The subagents communicate via a common subagent interface. A NE which supports both OSI and non-OSI interfaces such as Transaction Language 1 (TL1) and Common Management Services Element (CMISE) interfaces is provided, along with a method for mapping TL1 commands to CMISE messages using TL1 proxy objects.
