内容简介
XDSL是基于现有铜线环路发展最快的接入网传输技术，在商业和居民用户应用领域具有广泛的发展前景。本书做到了理论和工程的有机结合，是介绍同类技术图书中的典型代表。该书首先介绍了基于DSL的接入网结构和相关技术：调制、差错控制和数据压缩等，并比较了DSL技术与其它接入技术的异同；又重点讨论了典型的XDSL结构；如HDSL和HDSL2，ADSL和ADSL Lite以及VDSL宽带接入结构，同时还介绍了基于DSL传输技术之上的高层网络协议：ATM，TCP/IP以及PPP协议等；最后，对DSL技术中用户驻地设施和接入网体系结构、业务结构和宽带接入网设计等更加深入的话题作了详细的阐述。本书适合高校计算机、电子、电信以及相关专业的师生和从事网络技术的科技工作人员阅读。作者P·Warrier是美国IT公司负责接入网产品的资深研究员；B·Kumar是Tele Hub通信公司的高级副总裁，对接入网结构和宽带技术具有丰富的阅历。
