一起101双通道交叉连接故障的解析

The cross-connect failure analysis of 101 dual-channel

讲述了一起双路101通道交叉连接引起的故障。介绍了故障现象,详细说明了故障排查过程中所遵循的思路和方法;通过分析故障现象,剖析101通道连接图在正常和交叉两种方式下的通讯机制,准确地锁定了故障点,成功地排除了故障;并提出了在远动通道调试过程中保障通道的独立性、可用性几点建议,对提高远动通道的运行率具有重要意义。

This paper describes the cross-connect failure analysis of 101 dual-channel, the phenomenon of failure, and the detailed description of the process followed by troubleshooting ideas and methods. By analyzing the phenomenon of failure, and the communication mechanism of 101 channels in normal and cross-connection diagram, it accurately identifies the failure point, successfully solves the problem and puts forward some suggestions in the telecontrol channel debugging process to protect the independence of channels and availability. It is of great significance for improving the operation rate of remote access.
