摘　　要：本文概述了一种利用公共总线，公共存储器，环路控制模块间轮循占用公共总线，进行多模块计算机间通讯的控制方案。说明了实现此方案的两种类型模块：交换模块和管理模块的硬件结构各部分的功能和作用及软件实现的概况，此方案在２００门至２０００门模块化扩容程控交换机设计中得到理论和实验的论证。Described in this paper is a control scheme of adding PABX modules with the use of common bus, common memory and multimodules taking common bus polling in turn to get communication among PABX modules CPUs. The paper also explains in detail the functions and effects of PABXs switch modules and control modules about hardware structure and softwate implement. The scheme has been proved by several units and found application.
