一种具有交换功能及速率可变的IP电话技术

The IP phone technology of switch function and variable rate

将具有交换功能以及速率可变的IP电话技术应用于SDH设备中,这样可以解决传统二线电话在SDH设备中只能点对点呼叫、占用固定带宽的缺点I,P电话之间可互相呼叫并调整占用的带宽。主要介绍了将IP电话技术应用于SDH设备组网的设计方案。

IP phone, with the function of switch and rate adjustment, can be used in SDH devices to solve the disadvantage of usual 2-wire phone＇s point to point communication and fixed usage of bandwidth, while IP phone can also reach each other with optional bandwidth. In this article, we will introduce a design of how to use IP phone in SDH devices network.
