基于SDH网络的MSTP技术疑难故障的处理

One elimination of SDH network based MSTP′s malfunction

结合徐州供电公司网络的实际情况,介绍了基于SDH平台提供多种业务接入的混合传输MSTP设备的相关技术。对徐州供电公司采用的二纤环子网连接保护(SNCP)工作方式的网络故障处理过程进行了探讨,分析了线路误码对TDM业务和数据业务的不同影响的表现形式。通过对该起疑难故障的处理和剖析,抛砖引玉,希望能对基于SDH网络的MSTP技术新问题的处理提供一定的借鉴作用。实践证明,数据业务比TDM业务对误码的指标要求更高。

The paper introduces the correlational technologies of SDH network based muhi service transport platform. Combining with the real network of Xuzhou Power Supply Company, it introduces the MSTP produced by Lucent Technologies Company briefly. Through elimination of network malfunction about SNCP＇s operating mode on two fiber rings, author analyzes the different influences of error codes on TDM and MSTP service. Rely on it, we try to provide one paradigm on resolving MSTP＇s fault for network service provider and engineers of VPN when we utilize MSTP new technology on traditional SDH network. Practice has proved that data service should have more rigorous requirement about error codes than TDM service.
