摘　　要：随着下一代网络的逐步推广,软交换系统在交换网络中的应用日趋广泛。公共电信网络已逐步将电路交换机更新为软交换系统,电力PSTN与公网软交换系统的组网问题日益突出。而HARRIS交换机在电力系统中有着广泛的应用,人们常认为HARRIS交换机使用中国七号信令与电路交换机组网只能是点对点的连接,不能直接与软交换系统的两个Sever点进行连接。经仔细分析HARRIS交换机应用的中国七号信令的体系结构与软交换接入网关的作用进行对比后,通过实际组网测试,最终成功组网。With the development of the next-generation telecommunications network（NGN）,soft switch system has been widely deployed in switching network.The replacement of circuit switch system by soft switch system in public telecommunication network causes some networking problems between PSTN in power communication network and soft switch system in public telecommunication network.Harris switching system has been used widely in power system,some people think that HARRIS exchange cannot be connected directly to two servers in soft switch system since it uses Chinese No.7 signaling,and can only point-to-point connect to circuit exchanges.This paper analyses the architecture of Chinese No.7 signaling system used by Harris exchange,compares it with the access gateway of soft switch network.The test shows that the networking is successful.
