移动电话传输网同步问题的探讨

The Issues of Synchronization in the Mobile Telephone Transmission Network in Jiangsu

近年来,SDH设备越来越多地应用在移动网的传输电路中,但利用SDH设备组网时常受到网同步问题的困扰。本文分析了江苏省移动网PDH和SDH两种传输体制混用的现状及产生时钟抖动的原因,并探讨了解决基站同步问题的方法。

In recent years, more and more SDH equipment can be found in the mobile networks; however, synchronization has been more often that not a troublesome issue to SDH equipment networking. In this paper, the present status of the coexisting PDH and SDH systems in Jiangsu mobile network and the reasons for clock jitter are analysed, and the solutions to the base station synchronization have been discussed.
