近期,由于微处理机技术的发展,使小型程控交换机得到了广泛的应用。北京邮电学院于1979年研制成了100门程控电视电话交换机的性能样机,该机的硬件和软件结构都比较简单,主要作为教学模型用。本文介绍该交换机的程序结构,重点是呼叫处理程序的方案特点和基本结构,并提供了大部分呼叫处理程序的流程图,可供希望了解程控交换软件基本技术的同志参考。
Recently, due to the development of microprocessor technology, small program-controlled switches have been widely used. Beijing Institute of Posts and Telecommunications in 1979 developed into 100 program-controlled TV telephone switch performance prototype, the aircraft hardware and software structure is relatively simple, mainly used as a teaching model. This article describes the program structure of the switch, focusing on the program features and basic structure of the call handler, and provides most of the call handler flow chart, for those who want to know the basic technology of program-controlled switching software gay reference.
