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。
The IP phone system on the HFC in the MGCP system fully utilizes the CATV network resources and fundamentally meets the needs of large-scale IP phone service. Based on the discussion of IP telephony system on HFC, a CableModem-based IP telephony adapter designed to process two voice signals at the same time is proposed.
