Abstract

This interface includes three comparators, the inputs of the first comparator being connected to the two transmission lines, one of the inputs of the second comparator being connected to one of the transmission lines and the other input of this comparator being connected to a bias voltage generator, one of the inputs of the third comparator being connected to the other transmission line and the other input of this comparator being connected to the bias voltage generator. The outputs of the comparators are connected to inputs of a multiplexer whose output is connected to the remainder of the circuits of the station, and the control inputs of the multiplexer are connected to the output of defect detecting means for detecting defects of one of the transmission lines so that the transmission lines control the multiplexer in such manner that the multiplexer selects the output of one of the comparators as a function of the state of the transmission lines.
