According to one embodiment of the present invention, a system (10) for data communication disclosed that comprises a first transceiver unit (20), a second transceiver unit (22), and a communication path (34) coupled to the first transceiver unit (20) and the second transceiver unit (22). The first transceiver unit (20) is operable to perform compression negotiation with a second transceiver unit (22). More specifically, the first and second transceiver units (20 and 22) may comprise ADSL transceiver units, and the communication path (34) may comprise a twisted-pair cable. According to one embodiment of the present invention, a method for data communication is disclosed. First, a first transceiver unit (20) and a second transceiver unit (22) are initialized. The first transceiver (20) then communicates a request for compression negotiation to the second transceiver unit (22). A common compression protocol is then identified. Finally, the first transceiver unit (20) transmits data compressed using the common compression protocol to the second transceiver unit (22).
