广电系统SDH传输网络故障的分析与处理

Radio and Television Systems SDH Transmission Network Fault Analysis and Processing

对广播电视SDH传输网络的结构特点进行分析,着重介绍了影响SDH传输网络安全的常见故障、告警分析、故障定位及SDH自愈保护环的启动机制。通过SDH设备实际维护过程中遇到的典型故障案例,从网络系统的角度去分析告警现象,探讨处理方法,为SDH传输网络的故障分析处理提供参考。

In this paper, radio and television SDH transmission network structure characteristic is analysised, the effects of SDH transmission network security common fault,alarm analysis,fault location and SDH self-healing ring starting mechanism are emphatically introduced. Through the SDH equipment and the actual maintenance encountered in typical fault cases, a network system from the point of view to analyze the phenomenon of alarmis is proposed, and provides reference for SDH transmission network fault analysis.
