Interchange circuit
Encyclopedia
In telecommunication
, an interchange circuit is a circuit
that facilitates the exchange of data
and signaling information
between data terminal equipment
(DTE
) and data circuit-terminating equipment (DCE
).
An interchange circuit can carry many types of signals and provide many types of service features, such as control signals, timing signals, and common return functions.
Telecommunication
Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded...
