SDH设备交叉模块的测试技术

Testing technology for across connect module of SDH equipment

文章介绍了同步数字体系(SDH)设备交叉模块的测试技术。它可以对交叉模块进行快速的全面测试,也可在交叉模块不正常时进行准确的定位,同时持续送出测试信号便于检修。文章首先介绍了研究课题的背景及意义,然后简要介绍了交叉模块的工作原理,最后详细介绍了高、低阶交叉模块的测试方案。经过实际运行和测试,证明了系统设计的可行性和可靠性。

This paper introduces a testing technology for cross connect module of SDH equipment. It can conduct fast and all-round test for cross connect module. It may judge failure and send signal constantly for conner to maintain when the module is at fault. The article firstly introduces the background and meaning of this research, then the theory of operation for cross connect module. After that, testing technology of cross connection with granularity at VC-12 and VC-4 is illustrated in detail. Practical running and testing proved the design's feasibility and reliability.
