Synchronization in Digital Telephone Network

本文从滑码对通信质量的影响开始,提出了全程滑码率的标准,并对CCITT建议的G.822内容进行说明。本文分析了网同步的方法与网络结构,提出了各种同步的网络结构及在各种情况下的选用方法。

This article dealswith the effects of slip upon communication quality, puts forward the standards of all-route slip rate, and explains the contents of G. 822 proposed by CCITT. The article also analysis the ways of network synchronization and the network structures, ans suggests variety of synchronizing network structures and their selected uses in different situations.
