Abstract
A method for reducing power consumption on an xDSL subscriber board, includes: obtaining a maximum downlink service bandwidth, a downlink signal-to-noise ratio margin in line connection parameters of the user port, and transmission mode information in a line template bound to the user port; determining whether the downlink signal-to-noise ratio margin is larger than a preset value, if yes, reducing a maximum downlink nominal total transmission power; otherwise, configuring the maximum downlink nominal total transmission power as a downlink transmit power in line connection parameters of the current port; calculating a minimum undistorted power supply voltage required by a corresponding line driver of each registered user port under the current configuration of the bound template, comparing minimum undistorted power supply voltage values, to find the largest value; and controlling an output voltage of a power module of a line driver equaling to the largest value.
