中文摘要:

      针对某通信系统中的各类型交换设备之间不能相互通话的情况，研制了电路交换板，使各交换设备之间可进行话音互通。首先阐述了呼叫处理的一般过程和软件设计方案，重点说明了板中信令交互软件研制中所实现的信令模块划分、任务通信、E1信令等关键部分的解决策略。该软件的正确性已通过装备试验验证。

英文摘要:

      Aiming at the situation that communication systems cant speak to each other between the various types of switching equipment,a circuit switching board is developed.It is to enable voice intercommunication between the switching equipments success.First,the general procedure of call processing and design scheme of the software are explained.Then the solutions of the key parts in the process of the signaling interaction software design are emphasized with details,such as signaling modules division,tasks communication,E1 signaling and so on.The correctness of the software is verified through equipment tests.
