【摘要】 为了适应农村通讯网发展的需要，本文开发了一种中小容量的数字程控Ｃ５局用交换机，在介绍几种交换软件结构的基础上，提出了一种以层次结构为基础的五级管理的交换软件结构。该方法可使软件运行效率较高，便于系统调试和维护。该结构已在ＣＩＰＴ－２０００程控交换机上实现。并给出了系统实现流程图。更多还原

【Abstract】 Under the necessity of developing the rural communication network and based up- on the overview of several kind of switching software structure, a small or medium capacity digital program-control switchboard for C5 terminal office is developed.On the basis of layer structure a kindof five-grade management switching software structure is provided. This methed raises the software working efficiency , facili-tates the system testing and maintainance and has been realized on CIPT-2000 pro-gram control switchboard; the system flowchart is also shown.更多还原
