METHOD AND DEVICE FOR SAVING POWER IN DIGITAL SUBSCRIBER LINES

摘要

A method for saving power on a digital subscriber line (xDSL) includes: making statistics on data rates on the xDSL; adjusting the line rate and the transmit power on the xDSL according to the statistic results; and updating the line rate of an xDSL transceiver according to the adjusted line rate and transmit power. An apparatus for saving power on an xDSL includes a data rate statistics unit, a line rate adjustment policy unit, a line parameter adjusting unit, and a line rate updating unit for an xDSL transceiver. According to the invention the average transmit power of the xDSL line can be reduced effectively and energy can be saved.
