Detailed explanation-1: -When a communication link is shared by time-division multiplexing, time is divided into frames. Each frame is divided into time slots that are allocated in a fixed order to the different incoming channels.
Detailed explanation-2: -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.
Detailed explanation-3: -Digital telephony primarily utilizes Time-Division Multiplexing (TDM) to send multiple data streams, or messages, in a single communication path. TDM is based signals being transmitted in tiny increments of time. TDM is split into two separate categories: synchronous and asynchronous.
