| 摘 要： | 目前,ADSL是xDSL中最受关注的宽带接入技术,它的优点是以广泛分布的双绞线为接入媒介,同时它可以利用点到点网络结构给组网带来很大的灵活性.本文以ADSL系统研制为基础,介绍了采用ATM over ADSL结构时宽带接入系统的构成,重点介绍了该方式下ADSL局端线路卡和用户端系统的软、硬件实现.

| Abstract: | Currently,Asymmetric Digital Subscriber Line (ADSL) is the most noticed technology in xDSL family.Using twisted-pair copper line as access medium is one advantage of ADSL because this medium has been widely distributed.Also,ADSL adopts point-to-point architecture,which brings more flexibility to set up networks.This paper is based on the development of ADSL system.It includes the architecture of ATM(Asynchronous transfer mode) over ADSL broadband access network.We concentrate our attention on hardware and software function designs of ATM over ADSL ATU-C and ATU-R cards. |
