1. A device for a multiplexer receiver in a system having a plurality of multiplexer receivers connected on a common communication line wherein each multiplexer receiver has a time period for reception relative to a multiplexer time clock, comprising in combination:

  • a counter circuit connected to the multiplexer time clock for providing a counter output upon registering a clock count between two preselected clock counts which correspond to the time period of the multiplexer receiver;

    a line receiver connected to the communication line for providing a line receiver output upon detecting a predetermined period of signal absence on the communication line;

    means connecting said line receiver output to said counter circuit for resetting said counter circuit after said predetermined period of signal absence;

    and means connecting said counter circuit output to the multiplexer receiver for enabling reception from the communication line only during a counter output of said counter circuit.
