本文以佛山供电局电力调控中心通信分部构建SDH光传输B网为例,以如何设置2M颗粒业务的自愈保护方式为切入点,逐步引入SNCP子网连接保护的SNCP-I与SNCP-N两种基于不同倒换条件的保护方式。通过网管配置实例分析,并对阿尔卡特SDH 1660SM光传输设备对自愈保护的具体配置特性作了较为详细论述。最后,还针对电力通信行业业务的特殊性,为光传输网络应用提出了若干建议。
This paper takes the SDH optical transmission B network constructed by Communication Division of Foshan Power Supply Bureau as an example, and how to set up self-healing protection mode of 2M granular service as the starting point, gradually introducing SNCP-I and SNCP-N Two kinds of protection methods based on different switching conditions. Through the example of network management configuration analysis, and Alcatel SDH 1660SM optical transmission equipment for self-healing protection of the specific configuration features made a more detailed discussion. Finally, some suggestions are also put forward for the application of optical transmission network in view of the particularity of the business of power communication industry.
