摘要
目前 ,ADSL是 x DSL家族中最受关注的宽带接入技术 ,它以广泛分布的双绞线为接入媒介 ,并利用点到点结构给组网来很大的灵活性。以 ADSL系统研制为基础 ,介绍了采用 ATM overADSL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。
Currently, ADSL is the most noticed technology in xDSL family. Using twisted pair copper line as access media is one advantage of ADSL because this media has been widely distributed. Also, ADSL adopts point to point architecture which brings it more flexible to setup networks. This paper is based on the development of ADSL system. It includes the architecture of ATM 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.
