基于PSTN和TCP／IP网络的通信实现

Communication Realization of Network Based on PSTN and TCP/IP

本文介绍了一种通信实现，采用了自定义的协议和分层模块化结构，将PSTN和TCP／IP两种不同的网络融合在一起，可在广域范围内实现带宽窄、干扰大、具有不同传输介质的网络的数据传输。系统具有成本低、抗干扰强、对带宽要求低和扩展灵活的特点，适用于分布比较广，条件参差不齐的企业内部连网，此设计思想及方法也可应用到其它结构的网络中。

This paper,introduces a communication, used to customize the layering modular structure and the user-defined protocol will be PSTN and TCP/IP two different networks togefller, It is implemented in the wide area that this action of data transmission can be achieved within narrow bandwidth, interference, with different media network. System has low costs, strong anti-interference, low bandwidth requirements and the characleristics of flexible expansion, are widely applicable to distribution, uneven conditions enterprise networking. Such ideas and methods can be further applied other network of frame work.
