time division multiplexing - (TDM) A type of multiplexing where two or more channels of information are transmitted over the same link by allocating a different time interval ("slot" or "slice") for the transmission of each channel. I.e. the channels take turns to use the link. Some kind of periodic synchronising signal or distinguishing identifier is usually required so that the receiver can tell which channel is which.

TDM becomes inefficient when traffic is intermittent because the time slot is still allocated even when the channel has no data to transmit. Statistical time division multiplexing was developed to overcome this problem.

Compare wavelength division multiplexing, frequency division multiplexing, code division multiplexing.

No references found			The new product is capable of carrying time division multiplexing (TDM), asynchronous transfer mode (ATM), synchronous digital hierarchy/synchronous optical network (SDH/SONET) and Ethernet over a reliable network, with resiliency at par with TDM networks. UTStarcom expands NetRing Transport Network product portfolio by Internet Business News While many of our customers are still relying on traditional Time Division Multiplexing for voice traffic, their migration routes through 3G require ATM support," said Mika Heikkinen, vice president and general manager of Tellabs Oy. TELLABS LAUNCHES END-TO-END NETWORK MANAGEMENT SYSTEM by Networks Update It can be deployed in a traditional Time Division Multiplexing (TDM) environment or Internet Protocol (IP), or any combination of both, NEC believes that the Aspire key system is well-suited for small and medium-sized businesses or larger corporations that have redistributed their workforces to branch or remote locations.
