综合业务数字网 (ISDN)是近 10年来发展较快同时也是代表有线通信未来发展的新型通信网。而且电话增加“可视”功能一直是通信目标之一。通过对规范 ISDN可视电话系列协议分析 ,提出一个基于局域网仿真环境的ISDN可视电话的设计方案
The Integrated Services Digital Network (ISDN) is a new type of communication network that has developed rapidly in the past 10 years and is also representing the future development of wired communications. And adding “visual” features to the phone has been one of the communications goals. By analyzing the protocol of ISDN videophone series, a design scheme of ISDN videophone based on LAN simulation environment is put forward
