摘要
以光纤接入的网络在不断扩大,但是传统的PSTN交换机还会在较长时期内继续使用。在软交换网络与PSTN网络并存时,PON用户与PSTN用户语音业务互通显得尤为重要。分别对不同情况下PON用户与PSTN用户语音业务互通的几种组网方式进行了描述,详细说明了每种组网方式下用户呼叫时的信令流及媒体流的路由。在实际应用中应考虑各种因素选择合适的组网方式。
The optical fiber access network is now in expanding, but the traditional PSTN switch would continue its use in a fairly long period. During the co-existence of soft switch network and PSTN network, PONand PSTNusers＇ voice business intercommunication is very important. This paper describes respectively the network modes of PON and PSTN users＇ voice business exchange under different conditions, discusses in detail the users call signaling and media flow routing in each network mode. Various factors should be considered in practical application, thus to choose a proper network mode.
