以同步数字体系(SDH,Synchronous Digital Hierarchy)数字微波设备网管系统功能为切入点,介绍了北京-武汉微波网管系统EMS的构成、网管接口之间的协议以及DCC通道、DCN组成,阐述了MS3201网管系统逻辑结构,重点分析了EMS和GNE、本地及远程操作终端、SMS之间的DCN通道组成以及微波网元之间、FOTS/MUX网元之间的协议组成。介绍了网管人员在日常运行维护中所遇到的问题如网元托管故障、微波设备故障、复接设备故障等,并提出与之对应的故障处理措施和方法,保障京汉微波设备的正常稳定运行。
This paper introduces the structure of Beijing-Wuhan microwave network management system EMS, the protocols of the network management interfaces and the DCC channel and DCN components by taking the function of the SDH (Synchronous Digital Hierarchy) network management system of the digital microwave equipment as an example. The network management functions of the MS3201 System logic structure, focusing on the composition of protocols between EMS and GNE, local and remote operation terminals, DCN channel between SMS and FOTS / MUX network elements between microwave NEs. Introduced the network management personnel in the daily operation and maintenance of the problems encountered such as network hosting fault, microwave equipment failure, multiplexing equipment failure, and put forward corresponding fault handling measures and methods to protect the normal stability of Beijing-Han microwave equipment run.
