<p>A method for adjusting Asymmetric Digital Subscriber Line (ADSL) transmitting power level is disclosed, and the method includes: acquiring a current noise margin according to a predetermined value of ADSL transmitting power level; calculating a current power reduction value according to the current noise margin and a predetermined noise margin; determining an adjusted ADSL transmitting power level for adjusting ADSL transmitting power level according to the current power reduction value and the predetermined value of ADSL transmitting power level. In the method of the present invention, the ADSL transmitting power level may be farthest reduced; and the power consumed by the driver circuit may be farthest reduced; the resource waste and the heat introduced by consuming powers also may be reduced. Then the impact made by mass heat dispersion for the life of communication device may be avoided; the crosstalk introduced by the adjacent line pairs may be reduced; and the line utilization is improved; in addition, in the method of the embodiment of the present invention, the cooperation between the CO and the CPE is nor necessary, and the operational state of CPE is not restricted.</p> |
