Abstract

A communication system comprises a first multiplexer card having a first plurality of time division multiplex (TDM) ports and a first differential signaling interface, wherein the first multiplexer card is operable to map timeslots from each of the first plurality of TDM ports to a first combined signal transmitted via the first differential signaling interface; a first unit having a second differential signaling interface coupled to the first differential signaling interface, wherein the first unit is operable to extract the timeslots from the first combined signal and to map the extracted timeslots to a digital subscriber line (DSL) frame for transmission over a DSL link; a second unit coupled to the first unit via the DSL link, the second unit having a third differential signaling interface, wherein the second unit is operable to extract the timeslots in the DSL frame and to map the timeslots to a second combined signal transmitted via the third differential signaling interface; and a second multiplexer card having a second plurality of TDM ports and a fourth differential signaling interface, wherein the second multiplexer card is operable to map each of the timeslots from the second combined signal to one of the second plurality of TDM ports.
