七号信令系统(SS7)以其高效率,灵活性正在深入数字电话交换同和ISDN实验同中。随着SS7的开通,对其测试、维护的需求日益迫切。本文遵照CCITT1988年1月颁布的七号信令测试规范修正草案,就故障检测工具提出七号信令协议分析仪的设计思想,讨论了两种设计方案,对实现过程中遇到的问题给出了有效的解决办法。 SS7 signaling system (SS7) with its high efficiency and flexibility are in-depth digital telephone exchange and ISDN experiments with the same. With the opening of the SS7, its testing and maintenance needs are increasingly urgent. In accordance with CCITT Draft Revision of SS7 Test Specification promulgated by CCITT in January 1988, this paper proposes the design idea of ​​SS7 Analyzer on fault detection tools, discusses two design schemes and gives the problems encountered in the implementation process An effective solution.
