Patent ID: 7227932

Claim:
A system for communicating information, comprising: a signal interface; a transceiver; a signal processor; an information source; a destination of information; a path coupled between the signal processor and the transceiver, wherein the path is a two-wire conductive path; a first branch coupled between the signal interface and the path, wherein the first branch is a two-wire conductive branch; wherein the source of information provides a first information set to the signal interface, the signal interface transmits a first signal onto the path, the transceiver receives the first signal from the path and provides the first information set to a destination of information, the signal processor transmits voiceband signals onto the path, receives voiceband signals from the path, and is operable to process telephone signals, the power spectrum of the first signal is substantially confined within a plurality of bands wherein (a) the bands of said plurality of bands are non-overlapping frequency bands, (b) a downstream band extends between a lowest frequency in the plurality of bands and a highest frequency in the plurality of bands, and (c) the downstream band is above voiceband, a first band and a second band are included in said plurality of bands, the first signal encodes information from the first information set in the first band, the first signal encodes information from the first information set in the second band, 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, and 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.
