Simultaneous data communication by one cable in two directions

Simultaneous data communication by one cable in two directions

Through one twisted pair of wires, or one cable it is possible to pass data simultaneously in two directions from two independent and not synchronized (between itself) sources (pic.1). In table 1. the state of output signals is shown at different values of input impulses. Circuit allows to carry out the double galvanic upshot between potentials of receiver and transmitter.
