摘要
IP-PCA(protocol converter A)是一个协议转换器,主要实现中国七号信令和IP协议的转换。设计目标是把16条PCM(2M/S)的中国七号信令转换为1条(10/1OO M/S)自适应lP信令协议的以太网接口,把电话交换设备通过IP-PCA连到IP网上去,使电话用户能够通过IP网进行长途电话业务。
IP-PCA is protocol converter A . It converts 16 numbers of PCM (2M/S) china NO.7 Signaling to a (10/100 M/ S)Ethernet interface of IP signaling protocol .The IP Signaling rate can be self-adapting (10/100M/S).A Telephone exchange Connects to IP network through IP-PCA so that Telephone subscribes can make toll call through IP network.
