基于局内自环测试的NO.7信令故障测试

基于对7.4版本A1000S12数字程控交换机No.7信令系统的研究,提出一种实用No.7信令故障测试的方法--局内自环测试.其硬件采用高速率的IPTM(Integrate Package Trunk Module)模块,软件采用直接修改数据库的方法.局内自环测试法比以往使用的MMC(Man machine Command)法方便、省时、省内存,能在没有对方配合的情况下快速地对己方的No.7系统进行故障测试.在实际交换机上已通过验证,运行结果表明,该方法可供维护7.4版本的A1000S12数字程控交换机人员参考和直接使用.

Method of No.7 signals failure test based on office inside own loop test

Owing to the research of No^7 signal system of the 7^4 edition A1000S12 digital program control exchange, people put forward a kind of method of practical No^7 signals failure test_office inside test from the wreath of No^7 signals. Hardware adopts the super-speed IPTM( Integrate Package Trunk Module) module. While the method software adopts is the direct modification of database. The method is more convenient than the former method called MMC(Man Machine Command),it can save time and inside save. It has the ability to test the No^7 signal system of the correspondence rapidly without any corresponding cooperation. That method is already verified on the practical exchange. The result shows that it can be referenced and used directly by the people who maintain the A1000S12 digital program control exchange of 7^4 editions.
