Time Division Multiplexing (TDM)
Explanation Posted: 12/02/01
A type of multiplexing that combines data streams by assigning each stream a different time slot in a set. TDM repeatedly transmits a fixed sequence of time slots over a single transmission channel. Within T-Carrier systems, such as T1 and T3, TDM combines Pulse Code Modulated (PCM) streams created for each conversation or data stream.
