Meridian交换机的管理与维护

介绍了加拿大北方电信Meridian综合业务数字程控交换机的系统构成、使用信令、维护显示器的电路卡板及其显示内容。结合工程应用实现了Meridian系列程控交换机的初始化方法和系统重新加载过程,对交换机运行过程中的故障进行了分类,给出了判断故障的思路,最后设计了程控交换机的雷电防护方法。

Meridian Switch Management and Maintenance

This article introduces the Canadian Northern Teleeom Meridian Integrated Services Digital program - controlled switchboard system composition, the use of signaling to the introduction of maintenance circuit card display board and the displaying contents of the note. Combining engineering applications achieves a series of program-controlled switchboard Meridian initialization method and system to re-load process. It classifies the failures taken place in the in the process of working, gives a way to the judge the fault line. Finallly the paper designs the program-controlled switchboard of lightning protection methods.
