1 问题的提出在一个智能、宽带的综合业务数字网络中,进行信息交换将采用“ATM交换模式”。用“ATM网络”表示采用ATM技术的宽带综合业务数字网络。在ATM网络中传递信令信息时,需要进行信令的适配,也就是将各种消息形式的信令消息转换成可在ATM网中传递的形式。完成这一功能的是信令ATM适配层 1 PROBLEM PROBLEM In an intelligent, broadband integrated services digital network, the exchange of information will adopt the “ATM switching paradigm.” Using “ATM Network” means using ATM technology, broadband integrated services digital network. When transferring signaling information in an ATM network, signaling adaptation is required, that is, signaling messages in various message forms are converted into forms that can be transmitted in an ATM network. The one that accomplishes this is the signaling ATM adaptation layer
