5、ADSL的网络结构包括4个子网部分：客户端网络，通信线路，局端接入网以及服务提供商网络。u电话是模拟信号，PC是数字信号uDB： Distribution Box 分线盒uCC： Connection Cabinet 交接箱uMDF：Main Distribution Frame，总配线架，即一侧连接交换机外线，另一侧连接交换机入口和出口的内部电缆布线的配线架uBRAS: Broadband Remote Access Server，宽带远程接入服务器,它位于网络的边缘，提供宽带接入服务、实现多种业务的汇聚与转发uRadius: Remote Authentication Dial In Us

6、er Service，远程用户拨号认证系统,是目前应用最广泛的AAA协议。AAA是一种管理框架，因此，它可以用多种协议来实现。在实践中，人们最常使用远程访问拨号用户服务（Remote Authentication Dial In User Service，RADIUS）来实现AAADB用户端滤波器PSTNModemCCPCTelephone电话外线局端Radius服务器BRASIp coreDSLAM电话交换机MDFIPTV服务器ATM/IP ZTE Corporation.
