基于POG模型的语音传真服务系统的研究与实现

通过引入“程序顶点向量”概念，定义语音传真应用系统的POG数学模型，介绍了基于POG模型的程序设计方法，即用POG模型描述应用软件的拓扑结构，不需修改源代码，只要编辑修改POG的描述文件，就可改变系统功能流程。POG模型的程序开发模式适合于所有基于后台事件驱动的系统。作为POG模型的应用，简述了以“DIALOGIC，VFX／40SC”语音传真卡为硬件支撑的“自动服务系统”的设计与实现。

Study and Implementation of Tel.&Fax Service System Based on POG

This paper introduces a method of programming, through the use of POG model, which is used as describing the topology construction of the application program, and make use of event driven mechanism to drive the program running. As a result, it doesn't modify the code but only to edit describing file of POG, then relevant service system has been made. It is suitable for all event driven-based software system. Finally, an example for POG model application is illustrated , supported by the VFX/40SC card. ;
