Abstract
A system and method of adding a high-rate channel to a legacy baseband bus includes a bus communicatively coupled to a transmitter and a receiver via one or more transformer couplers, where the transmitter and receiver transmit and receive a first signal over the bus utilizing a differential mode. The system also includes at least two modems coupled to the bus, where a first modem transmits a second signal over the bus for receipt by a second modem, where the at least two modems are each coupled to the bus via the one or more transformer couplers, where the second signal is transmitted over the bus utilizing a common mode, and where the first signal and the second signal are spatially separated on the bus based on an isolation between the common mode and the differential mode.
