摘要:
介紹了SDH原理及SDH時隙對接原則，針對綜合網管同網元級專業網管對接時后者無法提供通道的情況，給出了通過網元時隙交叉和拓撲連接得到通道的計算方法及詳細的實現過程，從而保證了綜合網管的電路業務資源管理功能及重要業務告警監視功能的正常運行。此外，文章給出了通道計算需要注意的一些事項，并介紹了該算法的實際應用情況。

Abstact:
This paper first talks about the SDH Principles and the principle of SDH time slot docking.Then,the SDH path calculation method and details of the implementation process by NE crossconnections and topologiclinks are introduced to solve the problem that SDH transmission network system can not provide SNC to integrated network management system, in order to ensure the circuit services resource management functions and the important business alarm monitoring function properly. In addition, some discussions concerning the algorithm and the practical application of the algorithm are also given in the end of the paper.
Key: Integrated Network Management System; SDH path calculation
