本文研究了一种新型低功耗CMOS智能化调制解调器的特点、性能和工作环境,完成了整机方案和所有单元电路的初步设计。这样,利用现有的各种程控交换电话网并由话路供电,就可在符合各种国际通讯协议(规程)的前提下实现不同距离上的计算机数据通讯。
This paper studies the characteristics, performance and working environment of a new type of low-power CMOS intelligent modem, and completes the scheme of the whole machine and the preliminary design of all unit circuits. In this way, using various existing PSTN exchanges and powered by voice channels, computer data communications at different distances can be implemented in compliance with various international communication protocols (protocols).
