摘要
介绍了铁路通信系统中常见的二纤双向复用段保护环的应用和机理;对二纤双向复用段保护环在单节点失效的情况下,造成的时隙错连进行探讨;针对铁路常见的几个时隙错连现象导致的问题进行详细分析,由此归纳出时隙错连产生的原因,为后期业务应用提出相应的规避措施。
The application and mechanism of common two fiber shared multiplexing section loop in railway communication system is introduced. And, time slot misconnection caused by single node failure is also explored. In addition, detailed analysis is made to several common problems resulting from time slot misconnection. Therefore, the reason of time slot misconnection is analyzed in hope of working out corresponding elusion measures for time slot misconnection.
