| 摘 要： | 目前用户接入网广泛采用混合光纤／同轴网（ＨＦＣ）和非对称数字用户线（ＡＤＳＬ）技术，在此基础上建立ＡＴＭ网实现ＡＴＭ到家以适应未来宽带网的发展需要。基于ＨＦＣ网的ＡＴＭ网以ＡＴＭ节点交换、用户终端单元和头端单元设备来作支持。而在ＡＤＳＬ上完成ＡＴＭ交换业务时，则有两种方案可选：（１）通过在ＡＴＭ交换机与ＡＤＳＬ调制解调器之间加数字用户线接入复用器实现；（２）将离散多音频（ＤＭＴ）与ＡＴＭ相结合。

| Abstract: | The HFC and ADSL - based ATM access network is built to meet the demands of the broadband network development. The HFC - based ATM network is supported by the ATM nodal switching, user terminal unit and headend unit. The ADSL - based ATM switching service is provided alternatively by the implementatin of a multiplexer between the ATM switch and ADSL modem; or the integration of DMT with ATM . |
