IP电话在HFC上的实现

Implementation of IP telephone over HFC network

合 ＭＧＣＰ体系的 ＨＦＣ上的 ＩＰ电话系统充分利用了 ＣＡＴＶ网络资源，从根本上满足了大规模ＩＰ电话服务的需要。在对ＨＦＣ上的ＩＰ电话系统进行讨论的基础上，提出了能同时处理两路语音信号的基于ＣａｂｌｅＭｏｄｅｍ的ＩＰ电话适配卡设计方案。

VoIP system on HFC that accords with MGCP architecture takes advantage of CATV network resources and meets the requirement of large--scale VoIP service. In this paper based on the discussion on VoIP system on HFC, a new scheme of design for cable modem-based VoIP adaptor that can process 2-channel speech signal at the same time is proposed.
