1. A method for multiplexing data communications, the method comprising:
- communicating to a modem, via an intermediate frequency cable coupled to a transceiver, data over a first frequency range; and
receiving at the transceiver, via the intermediate frequency cable, data communicated from the modem over a second frequency range,wherein the first frequency range and the second frequency range are separated by at least one octave;
wherein the data communicated over the first frequency range is carried via a first intermediate frequency signal; and
wherein the data communicated over the second frequency range is carried via a second intermediate frequency signal; and
wherein communication of said first and second intermediate frequency signals, over the intermediate frequency cable, is full duplex.

Abstract
A single-cable protocol and associated methods and systems enable improved communication efficiency and/or reduced cost. Transmit information, receive information, telemetry information, and/or DC power may be multiplexed onto a single cable, eliminating the need for multiple cables between a satellite transceiver and a corresponding modem while reducing and/or eliminating spurious emissions. Additionally, telemetry features enable improved diagnostics and/or repair of communication systems, for example satellite communication systems.
