基于ATM的话音交换技术

Voice Switching Techniques Based on ATM

利用ＡＴＭ网络进行电路仿真通信是当前ＡＴＭ应用研究的一个热点问题，通过对话音ＡＴＭ电路仿真技术进行分析，指出了这种工作方式在实际应用中存在的一些问题．在此基础上，提出了一种基于ＮａｔｉｖｅｍｏｄｅＡＴＭ的话音通信方式，并对其应用方式和关键技术进行了分析．实践证明，基于Ｎａｔｉｖｅｍｏｄｅ的工作方式提高了带宽利用率和系统整体效率，适用于语音数据集成的应用环境．

By analyzing the current serial of specifications on ATM Forum Circuit Emulation Services, some implementation problems related with this technique were proposed. Also, a voice communication model based on Native Mode ATM was presented. The essential techniques and implement methods were also discussed. This working mode can provide more efficient bandwidth usage and improve the system efficiency. It is suitable for Date Voice integration environment.
