Abstract : The patent relates to digital information transmitted in either direction on a time sharing basis over a single transmission line. Identical transmit/receive stations send out pulse signals of one polarity and detectors are adapted to receive pulses of the opposite polarity. The detectors block pulses of the same polarity as those that are generated and transmitted from its own station. A transmission line is transformer coupled to each station with an inversion in the line so that the signal received at the opposite station is of inverted polarity to that transmitted.
