Patent ID: 7564797

Claim:
A method for establishing at least one separate communication channel on a single twisted-pair telephone transmission line, the method comprising: interfacing a first transceiver unit with the single twisted-pair telephone transmission line, wherein interfacing is accomplished via a network interface device (NID) or a wall jack; operating the first transceiver unit to monitor a corresponding signal power level in each of a first plurality of predefined frequency bands for which the first transceiver unit is pre-configured to transmit and receive communication signals; operating the first transceiver unit to identify a first available frequency bands comprising to a lowest frequency band of the first plurality of predefined frequency bands having the corresponding signal power level that is less than a predetermined threshold signal power level; and establishing a first separate communication channel on the single twisted-pair telephone transmission line by operating the first transceiver unit to transmit and receive first communication signals over the single twisted- pair telephone transmission line within the first available frequency band.
