一种可实现PSTN/N-ISDN与ATM网络互通的网络适配器

Design of a Network Adaptor between PSTN/N ISDN and ATM Network

介绍了ＡＴＭ话音通信的关键技术，提出了一种可实现ＰＳＴＮ／Ｎ－ＩＳＤＮ与ＡＴＭ网互通的网络适配器（ＮＢ－ＩＷＡ），它通过采用一定的呼叫控制策略和信令的适配，实现了动态复合打包策略。

A kind of narrowband broadband network interworking adaptor(NB IWA) is presented after introducing some key technologies of VTOA. which exploits the dynamic composite cell mechanism to adapt the voice traffic into ATM cells and implements the signalling interworking between narrowband and broadband network.
