Abstract (en)
[origin: WO9965218A1] A modem (305) for communicating data using a plurality of tones includes a negotiation unit (45), a modulator (65), and a demodulator (90). The negotiation unit (45) is adapted to receive resource availability data and determine an available tone range based on the resource availability data. 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. The number of tones in the second plurality is based on the available tone range.
