• For recent years , adsl has world widely employed and widely used in many aspects such as vod , remote medical treatment and e - shopping etc . but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals , and the adsl ' s frequency rang is from 0 to 1 . 104mhz , so we must confront the signal attenuation , the loop line noise impairments , the crosstalk interferences , the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks
  近几年来， adsl在世界范围内得到充分的使用，广泛应用于视频点播、远程医疗、网上购物等各个方面。但是由于电话线网络是专门为传输低频信号而设计，而adsl的频谱范围在0 1 . 104mhz内，因此在传输adsl信号时，面临着信号衰减、线路噪声、串音干扰、桥接抽头反射和射频干扰等等多方面的问题，这就要求在adsl开通之前对线路进行一系列的测试。
