METHOD AND APPARATUS FOR SCALING MODEM TRANSFER CAPACITY

摘要

A modem (25) for communicating data using a plurality of tones includes a negociation unit (45), a modulator (65), and a demodulator (90). The negociation unit (45) is adapted to determine an available tone range. The modulator (65) is adapted to receive the available tone range and modulate a first plurality of the tones to generate outgoing data. The number of tones in the first plurality is based on the available tone range. The demodulator (90) is adapted to receive the available tone range and demodulate a second plurality of the tones to generate incoming data.
