摘　　要：随着铁路通信传输设备不断升级改造,传输网元数量不断增加,系统组网更加复杂,有效监控传输网管网元的状态尤为重要。通过对网络中常见的网元脱管现象及案例进行分析,总结出网管网元脱管的特点、处理方法及一般流程,以构建安全可控、节约维护成本的传输网络。在日常维护中,对SDH传输网元脱管障碍处理具有指导意义。Over recent years, railway communication and transmission equipment has been continuously upgraded, the number of transmission network elements has continued to increase and the network of railway communication system has become more and more complicated. It is particularly important to effectively monitor the status of network elements. Aiming at building safe and controllable railway communication network with low maintenance cost, handling methods and general procedures of network elements’ out-ofmanagement of SDH transmission network are summarized by analyzing common phenomena of network elements’ out-of-management occurring in the network, which is of significance for fault handling of network elements’ out-of-management in routine maintenance of SDH transmission network.
