时钟同步在电信传输网中的应用及其重要性

Application and Importance of Clock Synchronization in Telecommunications Transmission

论述了时钟同步问题在现代通信网及传输网中的应用及其重要性,并用实例说明日常维护中发现的一些时钟问题和解决方法。随着通信网络的发展,现代通信网的同步性能越来越高,基准定时信号的数量和类型增多的要求,数字同步网应用而生;从而调节通信网中的时钟以建立并保持同步、满足通信网传递业务信息所需的传输和交换性能要求,已成为保证网络定时性能的关键。

This paper presents the application and importance of clock sychronization in tele communications transmission, illustrates the clock time and solution of adily maintnence. With the development of morden communications hetuorks, the performance of synchronization is higher and higer, the amournt and type of timing signal increases, digital synchonized arises at the histonic moment; meeting the transmission and exchange performance requirements has been the key of assuring network timer performance.
