TDM is a digital technology under which individual signals (i.e., a stream of binary digits or bits) are interleaved in time to produce the multiplexed, composite signal. Under TDM, recurring time-slots or channels are created such that each channel carries the bits from an individual signal. The total transmission bandwidth is split among the time-slots, with each component channel getting some fixed percentage of the total signal bandwidth. This total signal includes not only the payload bits for various component channels but also bits for performing overhead functions. TDM signals have a frame structure that repeats at regular intervals.

TDM has a long history in telecommunication networks. Prior to the ...
