摘要
Abstract
Although the IP telephone network is developing rapidly,but for a long period of time,PSTN and VOIP are complemen⁃tary and competitive each other.The fusion and intercommunication of traditional telephone exchange network and IP network communi⁃cation can be implemented by the gateway.Aiming at access of EM signaling in enterprise private network communication to IP network, the trunk gateway supporting EM signaling is designed and implemented. The functional modules of EM signaling trunk gateway are introduced,the EM signaling inbound flow and outbound flow are described,and the two key technologies of protocol adaptation and redundancy processing in EM signaling gateway design are implemented. The trunk gateway supporting EM signaling can be used to implement smooth access from EM trunk in private network to NGN network,can be extended to support multiple simulated agreement and meet the application requirement of private network.关键词
