SYSTEM AND METHOD FOR CONTROLLING LINE DRIVE POWER IN DIGITAL SUBSCRIBER LINE MODEMS

Japanese Patent JP3583110

B2

PROBLEM TO BE SOLVED: To reduce electric power demand of the line driver of a DSL server modem, by limiting the bandwidth of signals to be transmitted to a related client modem (namely, limiting power in signals), excluding the case where a client is intending data reception in a current physical frame (not in idle state).
SOLUTION: A low-power DSL modem transmitter suited for incorporation into an integral DSLAM server line card transmits all the power physical frame, including a control channel and a data field when there are data to be transmitted, and transmits a physical frame having only the control channel or the control channel and a low-power synchronous field, when there are no data to be transmitted. By regulating the flow of data packets to the DSL selectively, a method for controlling total power consumed in the integral DSLAM is provided.
