摘要
随着通信设备数字化的更新换代及通信网络的日益复杂,数字同步网成为电信网络重要的组成部分,介绍了数字同步网的一般概念及采用的两种同步方式;我国数字同步网的概况;本地网时钟网的组网与应用以及对网络通信设备定时接口的技术及性能要求。
With the update on digitization of communication equipment and the increasing complexity of communication network the digital synchronous network becomes the important component of the telecommunication network. This paper introduces the gen eral concept of the digital synchronous network and two kinds of synchronous ways adopted; the overview of digital synchronous net work in our country; the network grouping and its application of clock network in local network as well as the requirement in tech niques and function for timing interface of network communication equipment.
