E1通信系统中的带内传输同步设置技术的研究

Research on in-band transmission synchronous setting technology in E1 communication system

提出了一种利用被监测的E1数据链路来进行保护倒换设备之间同步设置的技术。该技术利用被监测的传输线路来实现两倒换设备之间的信息传输,且不影响原有传输线路的传输内容。基于此技术研制出一种新型保护倒换设备,实验测试结果表明该设备实现了远端倒换设备与近端倒换设备之间的相互通信和近端设置远端同步功能。

A synchronous setting technology between protection switching equipments using E1 data link is proposed in this paper, in which the data is transmitted between two protection switching equipments through supervised transmission link, and the original transmitted data are unchanged. Based on this technology, a new protection switching equipment was developed. The test results show that the communication between remote and local protection switching equipments and double ended synchronization can be implemented.
