Patent ID: 7224780

Claim:
A transceiver for communicating information over a conductive path, comprising: a first receiver circuit configured to receive a first information set from an information source; and a first transmitter circuit coupled to the first receiver circuit and configured to transmit a first signal onto said conductive path, wherein the conductive path is a two-wire conductive path, the first signal is an electrical signal and a power spectrum of the first signal is substantially confined within a plurality of bands, the bands of the plurality of bands are non-overlapping frequency bands, a first band and a second band are included in said plurality of bands, wherein substantially all of the power spectrum of the first signal is confined to frequencies outside a band of frequencies separating the first band and the second band, information from the first information set is encoded in the first band, and information from the first information set is encoded in the second band, the first information set is recoverable from any signal that is created by excluding a portion of the first signal, wherein said portion is substantially confined within a band in the plurality of bands, and a transmitting band extends between a lowest frequency and a highest frequency in the plurality of bands and said lowest frequency is above 3 KHz; and a second receiver circuit configured to receive a second signal from said conductive path, wherein (a) a receiving band is a smallest band that encompasses substantially all of a power spectrum of the second signal, and (b) a lowest frequency of said receiving band is above 3 kHz.
