摘要
不同线路保护对通信通道有不同的要求。通过论述传输通道和线路保护的原理要求,分析通道衰耗和SDH自愈环倒换对时延的影响,总结出当选择2M复用保护通道作为线路纵差保护通道时,不宜使用通道自愈环功能的结论。
Different line protection type has different requirements on communication channel. This paper discusses the transmission channel and line protection principle requirements, analyzcs how channel attenuation and SDH self-healing switching delay affect line protection,and comes to the conclusion that while choosing 2M multiplexing channel as line differential protection channel,the channel should not use self-healing capabilities.
