    en.wikipedia.org/wiki/Time-division_multiplexing

    Multiplexing. Time-division multiplexing ( TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn. It ...
