TDM Bus

A TDM bus is one application of the principle of time-division multiplexing.

In a TDM Bus, data or information arriving from an input line is put onto specific timeslots on a high-speed bus, where a recipient would listen to the bus and pick out only the signals for a certain timeslot.

It resembles the TDM carried out in synchronous optical networking, but the "TDM Bus" term is more commonly used when the bus is inside a single unit like a telecommunications switch or a PC.

A specification for putting a TDM bus on PCI hardware has been published as H.100/H.110 by the Enterprise Computer Telephony Forum (ECTF).
