目前不少人在研究接入网、用户驻地网、 Ｔ Ｅ 以及网间接口，往往都是孤立地分析系统性能，而忽视了全网的互操作问题。本文认为应该从接入网的定界角度出发，综合分析接入网（ Ａ Ｎ） 、用户驻地网（ Ｃ Ｐ Ｎ） 、终端设备（ Ｔ Ｅ）以及网间接口，并全面考虑整个网络的互通性，才具有实际的应用意义。为此，本文从多个角度出发，通过对接入网、用户驻地网、业务节点等的分析，提出了一种基于 Ａ Ｔ Ｍ Ｐ Ｏ Ｎ 的宽带网解决方案 At present, many people are studying the access network, customer premises network, T E and inter-network interfaces, often in isolated analysis of system performance, while ignoring the entire network interoperability issues. This paper argues that the access network (A N), customer premises network (CPN), terminal equipment (T E), and inter-network interface should be comprehensively analyzed from the point of view of access network demarcation and fully consider the interworking of the entire network Sex, it has practical significance. To this end, this article from a number of perspectives, through the access network, customer premises network, business nodes, etc., based on A T M P O N broadband network solutions
