摘　　要：基于数字同步网的网络结构,提出了同步信号传递对SDH系统的具体要求和同步网建设改造方案,指出如何将SDH的定时组织与同步网网路组织有机结合,合理配置最佳传输链路,避免定时环路的产生。明确了时钟系统对SDH设备的时钟功能和性能的具体要求,提出了主用和备用时钟分成不同方向传输的环路时钟配置方案,及地区网络具体的建设方案,对地区局时钟系统建设与改造具有参考价值。Based on digital synchronous network structure, this paper puts forward both detailed requirements of synchronous signals transmission on SDH system and the upgrading scheme on existing synchronous network. It points out the way how to organize timing with routing on SDH network, and configure the best transmission link to avoid timing loop. It also explains the requirements of clock system on SDH equipments, proposes loop clock configuring scheme when main and standby clock transmitted at different direction. It has some reference value for the construction and upgrading of clock system in district power supply bureau.
