摘　　要：首先简要介绍了SDH网络保护方式,主要对常用的3种保护方式进行了分析比较,提出了自愈环的互通准则和互通结构,重点对SDH网络保护结构间的互通进行了探讨,以4种不同互通结构类型为例,对SDH自愈环互通的具体结构及工作原理进行分析说明。最后对复杂的SDH组网情况进行了举例分析,给出了网络拆分的基本原则,为复杂的网络建设提供参考。This paper briefly introduces the protection ways of SDH network and compares three common protection modes, then presents the rules and architectures of interconnecting of SDH network. This paper stresses the interconnecting of SDH network protection architectures and illustrates its detailed architectures and working principles by using four examples of different interconnecting architectures, Finally, analysis of the complicated SDH network and the basic principle for splitting SDH network are presented, which provides reference for constructing complex SDH network,
