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.
Famous quotes containing the words interchange and/or circuit:
“The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot function without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”
—Howard Brenton (b. 1942)
“each new victim treads unfalteringly
The never altered circuit of his fate,
Bringing twelve peers as witness
Both to his starry rise and starry fall.”
—Robert Graves (1895–1985)
