摘要
介绍了SDH自愈环的特点及环网保护机制,重点对2纤单向通道保护环及其生存性和网络互通进行了探讨,并根据电力系统通信的特点介绍了应用实例,最后对SDH自愈环及其生存性技术作了展望。
The paper introduces the characteristics of selfh ea lig ring network of SDH and the protection of ring network.Primarily,the surviva bility of unidirectional path switched ring of SDH and its interworking are ana lyzed.Then,according to the communication characteristics in electric power comm unication system,introduces the application of SDH in electric power communicati on system.Finally,discusses the future development of SHAR and its survivabilit y.
