Time division multiplexing (TDM) systems are designed to transport ________ between end point systems.

TDM does not transport analog signals - the time-slot assignment and framing mechanisms are digital processes that cannot accommodate raw analog waveforms.

TDM operates by dividing a transmission medium into fixed time slots and assigning each slot to a channel - an inherently digital process. Any analog source signals, such as voice, must first be converted to digital format via Pulse Code Modulation (PCM) before entering the TDM frame structure. As a result, TDM systems exclusively transport digital signals between endpoint systems.

TDM cannot carry a simultaneous mix of analog and digital signals - all traffic must be digitized and formatted into uniform digital bit streams before multiplexing.

TDM has no mode for transporting analog signals at any time - even one type at a time - because the architecture is exclusively digital from end to end.
