ABSTRACT:
A MUD enabled cable modem that provides efficient use of cable television network bandwidth in the presence of interference and noise is disclosed. The modem design provides for compatibility with existing network hardware and protocols so that bandwidth efficient modems configured in accordance with the principles of the present invention may be added to the network without removing installed hardware and software. A bandwidth efficient modem in the cable network head-end increases reverse link capacity from the terminals to the head end, while bandwidth efficient modems in cable network terminals increases forward link capacity from the head end to the terminals. Bidirectional bandwidth efficiency is thereby enabled.
