Time-division multiplexing (TDM) is a method of putting multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Each individual data stream is reassembled at the receiving end based on the timing. Channel combining (multiplexing) equipment operating in the frequency domain is known as frequency division multiplexing(F.D.M) while in the time domain it is known as time division multiplexing(T.D.M).
