Abstract:
1. A system for communicating information comprising: a subsystem, a transceiver, a signal interface, and an information source, a path coupled to the subsystem and the transceiver, wherein the path is a two-wire conductive path; and a first branch coupled to the signal interface and a first point on the path, wherein the first branch is a two-wire conductive branch; wherein, the subsystem transmits a first voiceband signal onto the path, receives a second voiceband signal from the path, and is operable to process telephone signals; the signal interface receives a first information set from the information source and transmits onto the first branch a first signal that encodes the first information set; the transceiver receives a second information set and transmits onto the path a second signal that encodes the second information set; the transceiver receives the first signal from the path, and substantially recovers the first information set from the first signal; and the signal interface receives the second signal from the first branch and substantially recovers the second information set from the second signal; and wherein the power spectrum of the first signal is substantially confined within a first frequency band; the power spectrum of the second signal is substantially confined within a second frequency band; a highest frequency of the second frequency band is below a highest frequency of the first frequency band; and a lowest frequency of the second frequency band is above voiceband and below a lowest frequency of the first frequency band.
