Abstract:
1. A local area network system utilizing a plurality of discrete multitone (DMT) remote units in communication with a central office providing digital subscriber line service comprising: a DMT transceiver central office unit; a master DMT transceiver remote unit connected to a local area network, wherein the master DMT transceiver remote unit provides a local area network timing reference for at least one other DMT transceiver remote unit when the DMT transceiver central office unit is not available; a set of DMT carriers providing a DMT communication link between the DMT transceiver central office unit and the master DMT transceiver remote unit; a slave DMT transceiver remote unit connected to the local area network; and a set of local area network carriers providing a local area network communication link between the slave DMT transceiver remote unit and the master DMT transceiver remote unit using timing derived from the set of DMT carriers providing a communication link between the master DMT transceiver remote unit and the DMT transceiver central office unit when the DMT transceiver central unit is available.
