马可尼S3系列和OMS1664系列传输设备MSP1+1保护测试分析

Test Analysis on MSP1+1 Protection of Marconi S3 and OMS1664 Transmission Apparatus

通过测试马可尼S3系列和OMS1664系列传输设备在正确配置和错误配置时MSP1+1保护的倒换过程,分析同步数字体系(synchronous digital hierarchy SDH)传输设备在MSP1+1保护倒换中的倒换机制及倒换过程中的业务传输流向,找出了因一次实施光缆业务转移过程中造成A变电站至B变电站光传输中断的真正原因,从而为广东电网电力通信设备的评测工作积累经验。

By testing switching process of MSPI ＋ 1 protection on the condition of right configuration and wrong configuration of Marconi S3 and OMS1664 transmission apparatus, the paper analyzes switching mechanism and flow of service transmission of synchronous digital hierarchy （SDH） transmission apparatus in switching of MSP ＋ 1 protection. Reasons of interruption of light transmission between substation A and substation B in a service shift are found out, which accumulates experience for assessment on communication equipment in Guangdong power grid.
