帧中继上的话音业务——ACTnetworks,Inc.的解决方案

Voice Services over the Frame Relay——A Solution by ACTnetworks,Inc.

帧中继是８０年代后期开始出现的一种新的数据通信方式与传输业务。它不仅适用于高速数据传输业务，同样也适用于低速业务。而且，除了数据传输外，国外目前尚在试验利用帧中继网进行压缩话音和压缩图像信号的传输。本文介绍了美国ＡＣＴ公司对帧中继上话音业务的解决方案。

The frame relay is a new method of data communication and a new transmission service.It was developed in the late 1980's and can be used not only for highspeed data transmission services but also for lowspeed services.Besides its function of data transmission,the FR is now being experimentally used to transmit compressed voice and compressed image signals in foreign countries.This paper describes the solution of voice services over the frame relay worked out by ACTnetworks,Inc.
