摘要

给出SDH网同步问题的一个总体描述。回顾了数字网网同步的发展演变

从抖动和飘动的角度讨论了网同步对SDH网的意义。还讨论了SDH网同步的基本原理、ITU—T建议G.81S对SDH时钟的定时要求。接着

介绍了G.81S钟硬件结构和操作原理

最后给出了我们设计的G.81S钟的一个实例。

Abstract

An overall description on the problem of SDH network sychronization is given. It reviews the development and evolution of network synchronization of digital network

discusses the necessity for SDH network synchronization from the viewpoint of jitter and wander in the network. The principles of network synchronization on SDH and requiement of ITU-T Rec. G. 81S on SDH clock are also investigated. Then

the hardware structure and operation mechanism of the G. 81S clock are presented. Finally

the G. 81S clock with good performance designed by us is presented.
