Abstract
Method and system for reducing power dissipation for data transmission from a transmitter to a receiver in a digital subscriber line (DSL) system when a rate of available data is below a first predetermined data rate for a predetermined length of time. The method includes the following steps. Normal parameters for a normal rate of said data transmission are stored. New parameters for a reduced rate of the data transmission are calculated. Data is transmitted at the reduced rate of the data transmission, wherein the reduced rate requires less power for data transmission. The normal rate of the data transmission is resumed using the normal parameters when the rate of available data rises above a second predetermined data rate.
