ABSTRACT:
A distributed network switching system includes a data network. The system also includes multiple access interworking function (A-IWF) devices each operating as a gateway that enables customer premises devices to directly interface into the data network. The system further includes a centralized control and signaling interworking function (CS-IWF) device that performs call control functions and administrative functions and is adapted to interface narrowband and broadband signaling for call processing and control within the data network.
