摘要：
A Digital Subscriber Line (DSL) modem determines the proper transnit power level in a splitterless environment by transmitting a probe signal at different power levels to a telephone set and measuring the distortion signal reflected from the telephone set for each power level. The proper transmit power level is determined by detecting the “comer point” of the reflected distortion signal.
