1. A method for determining a data rate using sub-band capacity in a communication network having a first modem in communication with a second modem over a communication channel, the method comprising the steps of:

  • receiving a signal from a first modem;

    determining from the signal, information concerning line conditions on a communications channel associated with the first modem;

    calculating an estimate of channel capacity using a geometric mean of capacities of a plurality of frequency domain sub-bands; and

    determining a data rate based on the estimate of channel capacity.
