Abstract: A network gateway is configured to facilitate on line and off line bi-directional communication between a number of near end data and telephony devices with far end data termination devices via a hybrid fiber coaxial network and a cable modem termination system. The described network gateway combines a QAM receiver, a transmitter, a DOCSIS MAC, a CPU, a voice and audio processor, a voice synchronizer, an Ethernet MAC, and a USB controller to provide high performance and robust operation. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

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.
