对二线制数据线路利用的再认识

Reinterpretation of Utilizing the Data Circuit of Two-wire System

二线制是运用最广泛的通信线路之一。今天,线通信路制式发生了很大的变化,从原来的二线制向着四线制和多线制的方向发展。本文从二线制发展的几个阶段对二线制进行了研究,对二线制的再利用提出了自己的观点和看法。

The two-wire system is one of the widely used communication lines. Nowadays, great changes have taken place in communication circuit, which is developing from the original two-wire system to the orientation of four-wire and even more wire system. Based on the developing stages of two-wire system, this paper makes a study of it. And it presents some ideas and suggestions for the reuse of two-wire system.
