ABSTRACT:
A multiplexer transmitter terminator is disclosed for connection to a multiplexer transmitter in a system having a plurality of multiplexer transmitters connected on a common communication line. Each of the multiplexer transmitters is assigned a time period for transmission relative to a multiplexer time clock. The improvement includes a counter circuit connected to the multiplexer time clock for providing a counter output upon counting a preselected number of clock pulses which output corresponds to the time period assigned for transmission of the multiplexer transmitter. A line receiver is connected to the communication line for providing an output upon detecting a predetermined period of signal absence on the communication line. The line receiver output is connected to the counter circuit to reset the counter after the predetermined period of signal absence. The counter circuit is connected to the multiplexer transmitter for enabling transmission through the communication line only at the time period assigned to the multiplexer transmitter. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
