SYSTEM AND METHOD FOR CONTROLLING LINE DRIVER POWER IN A SHARED DIGITAL SUBSCRIBER LINE MODEM

摘要

PROBLEM TO BE SOLVED: To substantially reduce the overall power requirement of a line driver connected to a digital subscriber line DSL by limiting a bandwidth of a signal transmitted to all subscriber lines other than those connected to an intended recipient of a physical data frame. SOLUTION: A shared digital subscriber line modem achieves reduced total power consumption and aquires data security by generating and transmitting a physical data frame which includes a control channel and a data field to only the connected client modem associated with the intended recipient. A second physical frame which does not include the data field is generated and transmitted to all of the other connected client modems.
