Each module communicates with the management unit over a message channel (30). The system provides a flexible interface (32) for various network communication services, such as, narrowband POTS, BRI, DDS, Ethernet and SDSL services, as well as wideband DS1 and protocols, such as ATM, frame relay, IP. A management system is provided to enable a user to exercise, configure and test the system.
