Abstract: A time-division-multiplex subscriber circuit provides the synchronous transfer of dial signals and teleprinter character signals into a time-division-multiplex system by means of a buffer and a pair of flip-flop devices in response to differences in the changes of polarity of the signals and at least one counter in cooperation with a divider for dividing the clock rate of the multiplex system down to the character signal repetition rate when one of the flip-flop devices is energized. The character signal repetition rate also controls the clock input of the buffer storage device so that the pair of flip-flop devices, the counter and divider become reset when the counter has reached a predetermined counting value.
