话音保密中继失步问题分析与解决

针对多个网络节点同时存在的话音保密中继失步现象,根据以往数据传输中解决类似问题的工程经验,以通用数据接口规范为参考,通过检查同步接口发送时钟方式设置和信号时序关系,发现接口间时钟设置不一致和信号时序关系不匹配,据此对问题产生的机理进行了分析。采取相应解决措施后,经长期使用验证,取得良好效果,并可使故障复现,彻底消除了存在多年的隐患。

Analysis and Solution to the Voice Secure Relay out of Synchronization

In order to solve the problem of voice secure relay out-of-synchronization in different network nodes, measures are taken into account according to the similar engineering experience of data transmission in the past. According to the specifications of the universal interface, signals are found unmatched after timing-mode setup and timing relationship between the equipment synchronous interfaces have been checked. The problem is hereby analyzed and the causation is studied. At last a solution is put forward and it is proved good after long-term use. The solution enable abnormity phenomenon in former status to recur and the problem having existed for years is settled thoroughly.
