1. A cable modem termination system for a cable plant comprising:

  • a burst receiver for processing data signals having physical layer parameters transmitted on an upstream channel of the cable plant;

    a transmitter for sending messages on a downstream channel of the cable plant to cable modems;

    a monitoring circuit for collecting packet based statistics representative of the quality of the upstream channel, the monitoring circuit sending a message to the transmitter for the cable modems to change a physical layer parameter responsive to the collected statistics and to the burst receiver to process data signals based on the changed physical layer parameter.
