The present invention enables the self-diagnosis functionality by embedding a cable modem with the CMTS system with mechanisms to redirect the signals from external connections to the embedded cable modem, thereby enabling the end user to fully test the CMTS using a suite of diagnostic tests. The embedded cable modem integrates the external CM, computer and diagnostic software in the chassis, or alternatively onto the CMTS card in the chassis. The invention enables the end user to fully test the functionality as a stand-alone unit, without relying on any external test equipment or methods. It also enables the end user to diagnose the CMTS from a remote location. Another major advantage of the present invention is that it enables the CMTS/CM function to be verified over the entire physical layer parameter set (frequency, symbol rate, FEC, signal levels, etc.) while not interrupting any of the services that are on the 'live' HFC plant.

A system and process for directly and flexibly switching connections of data packet flows between nodes of a broadband data processing system network. The system acts as a single IP switch.

System and process for high-availability, direct, flexible and scalable switching of data packets in broadband networks

An interface port expansion device (302) allows for more than one terminal equipment (304, 306, 308 and 310) having embedded U-interface termination's to interface to the ISDN via the U interface. The port expansion device (302) can take the form of a separate stand-alone device or a circuit which is integrated into a terminal apparatus. The port expansion device (302) includes a plurality of local (secondary) U interface ports (314, 316, 318 and 324) for interconnecting the terminal equipment (304, 306, 308 and 310) and a network side U interface (312) for interconnection to the ISDN. In other aspects of the invention, methods for allowing a plurality of terminal equipment having embedded U-interface terminations to receive messages from and transmit messages to the Integrated Services Digital Network (ISDN) via a single network side U-interface are described.
