How does T-1 multiplexing work?

T-1 multiplexing combines multiple voice and data channels into a single high-capacity transmission line. It operates using Time Division Multiplexing (TDM), where each channel is allocated a specific time slot in a repeating cycle. Typically, a T-1 line transmits 24 channels, each capable of carrying 64 Kbps, resulting in a total bandwidth of 1.544 Mbps. This efficient allocation allows multiple conversations or data streams to occur simultaneously over a single physical line.
