摘要
SDH是一套可以进行同步数据传输、复用和交叉连接的标准化数字信号等级结构,随着通信网络传输、交换、处理大量信息向数字化、综合化、智能化、个人化发展,作为通信网络的承载体传输网需要宽带化、规范化,SDH应运而生。其具有强大的运行维护管理(OAM)功能,由光传输设备所组成的环形网络能够为传输链路提供环网保护,具有自愈保护功能。文章以上海浦东华为SDH光环网的日常运行维护为例,分析了如何进行SDH光环网的日常告警清理及故障处置工作,以便更好地助力通信网络运维工作。
SDH is a hierarchical structure of standardized digital signals that can be used for synchronous data transmission,multiplexing,and cross connection.With the development of communication networks for transmitting,exchanging,and processing large amounts of information towards digitization,comprehensiveness,intelligence,and personalization,as the carrier of communication networks,transmission networks need to be broadband and standardized.SDH emerged with powerful operation and maintenance management(OAM)functions,The ring network composed of SDH optical transmission equipment can provide ring network protection for the transmission link and has self-healing protection function.Starting from daily operation and maintenance,the Huawei SDH optical ring network system in Shanghai Pudong has gained experience in daily alarm cleaning and fault handling work.With careful consideration and expertise,it can better assist in the operation and maintenance of communication networks.
