交换机维护调试经验交流

Discussion on Exchange Maintenance and Debugging

随着通信行业的飞速发展,语音交换机局间互连由原来的二线环路、四线E/M、中国1号信令等模拟中继逐步过度到使用7号数字信令相连。7号信令由于速度快,具有改变和增加信令的灵活性,便于开放新业务,故广为交换机局间互联使用。秦皇岛发电有限责任公司交换机局间通信方式采用7号信令,互连调试工作中遇到几个比较典型的局间通信异常现象,在此将处理过程和解决方法做一简单介绍,供交换机维护人员参考。

With the rapid development of communication industry,the interconnections among between voice switch-boards gradually evolves from the second loop line,four E / M,China No 1 signaling,and other analog trunks to No.7 digital signaling.No.7 signaling,for its high speed,flexibility in changing and increasing signaling,and convenience in opening a new business,is widely applied in the interconnection among between the switch-boards.No.7 signaling is adopted as the communication mode among between among the switch-boards by Qinghuangdao Power Plant Co.,Ltd.,and several typical communication anomalies are encountered in the interconnection debugging.Here the solutions and handling processes are briefly described,and these would serve as references for exchange maintenance work.
