TDM Telephony
TDM stands for Time Divisional Multiplexing and is the traditional method of sending multiple phone conversations (or signals) down a single wire. It achieved this by dividing multiple conversations into equal fixed-length time slots and alternately sending a small piece of each conversation down the wire at a time. Both the sender and receiver were synchronised so that the conversations could be reassembled again.
