摘要
本文研究程控数字电话交换机中用户集中器时分接线器(LTSW)的多故障检测.建立了 LTSW 的故障模型.设计了检测 LTSW多重故障的算法.详细介绍了算法原理及其实现.并以本文算法为基础设计了程控数字电话交换机用户级话路子系统故障检测程序.
In this paper,multiple fault detection of line concentrator time switch in SPC switching system is discussed.The fault models for LTSW are presented. The algorithms being capable of diagnosing multiple faults in this LTSW are de- vised.The algorithms and their applications are explained in some detail.The di- agnosis programs based on the algorithms given here for line concentrator speech path subsystem have been designed.
