摘要
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。
Based on network management of SDH system,the EMS composition,network management interface,DCC channel,DCN,MS3201 logical structure of Beijing-Wuhan Microwave Network Management System are described,the transmission channel between EMS and GNE,Local Craft Remote Terminal,SMS,and the protocol between Radio NE and FOTS/MUX NE explained,and the faults of network element trusteeship failures of microwave equipment and multiplexing equipment encountered by administrators analyzed,and the corresponding solutions suggested,thus ensure the normal operations of Beijing-Wuhan Microwave Network Management system.
