DSL线路速率分析与工程应用

DSL作为宽带接入的主要方式,对用户速率要求日益严格。通过梳理不同宽带接入典型场景,比较其实现区别,总结出用户环路是影响DSL速率的关键因素。通过研究用户环路线路特性,总结了DSL线路基本要求。依据上述因素归纳了与线路速率相关的DSL重要参数及其之间关系。结合工程应用提出了DSL速率提升方法,并通过故障实例进行了探讨。

DSL line rate analysis and engineering application

As the primary way of broadband access, the requirements of user rate become more stringent for DSL.Through combing the typical scenarios,we compare the distinction of realization from different scenarios, the subscriber loop as the key factor affecting the DSL rate is reported. By studying the characteristics of the subscriber loop line, we summary the basic requirements of DSL line. Based on the above factors, we induce the important DSL parameters influencing the line rate and the relationship among them. Combined with engineering application, we raise the method to enhance the DSL rate and have carried on the discussion through the fault instance.
