Time Division Multiplexing (TDM)
Time division multiplexing is a method of carrying several signals on one link by giving each a repeating time slot.
What is Time Division Multiplexing (TDM)?
TDM is the basis of traditional digital telephone networks, where each voice channel has a fixed 64 kbit/s slot. As networks move to IP, TDM traffic is converted at media gateways or carried by emulation.
