Abstract:In the DSL environment,Because the cable internal line of unshielded and crosstalk caused by electromagnetic coupling,Crosstalk noise caused by XDSL rate decreased very repetitive training and effect of service quality. In this paper, analyses the causes of the crosstalk performance loss caused by the training and discusses the method to solve the stability problem of crosstalk. |
