| 摘 要： | 数字用户线(DSL)技术是国内宽带接入的主流技术,DSLAM(DSL接入复用器)是目前广泛使用的局端宽带接入设备。文中从传输速率、传输距离等方面介绍了ADSL(非对称用户线)、SHD-SL(单线对高速数字用户线)、VDSL(甚高速数字用户线)等多种DSL技术特性,讨论了DSLAM与DSL的复合技术,提出基于SHDSL技术的高速对称数据传输方案将成为IP-DSLAM系统的发展方向。还对基于SHDSL技术的IP-DSLAM网络结构、工作原理进行了阐述。

| Abstract: | DSL techniques are still the main ones of broadband access in the days to come realistically.Digital Subscriber Line Access Multiplexer is widely used as broadband access equipment.This paper introduces ADSL,SHDSL,VDSL and other DSL techniques,and discusses the combination with DSLAM and DSL techniques,predicts that the high-speed symmetrical data transmission based on SHDSL would be used in IP-DSLAM system.Finally,it introduces the network construction and working principle of IP-DSLAM based on SHDSL. |
