DATA TRANSMISSION. The transfer of information from one place to another or from one part of a system to another. The sending of data from one place to another by means of signals over a channel.

DCE. An abbreviation for data circuit-terminating equipment. In a data station, the equipment that performs functions, such as signal conversion and coding, at the network end of the line between the data terminal equipment (DTE) and the line, and that may be a separate or an integral part of the DTE or of intermediate equipment. The interfacing equipment that may be required to couple the data terminal equipment (DTE) into a transmission circuit or channel and from a transmission circuit or channel into the DTE.

De-jitterizer: A device that reduces jitter in a digital signal.

DIGITAL SUBSCRIBER LINE (DSL). In Integrated Services Digital Networks (ISDN), equipment that provides full-duplex service on a single twisted metallic pair at a rate sufficient to support ISDN basic access and additional framing, timing recovery, and operational functions.

DRAIN WIRE. An uninsulated wire in contact with a shield throughout its length, used for terminating the shield.



DUMMY LOAD. A dissipative but non-radiating device that has the impedance characteristics of an antenna or transmission line. Also called ARTIFICIAL LOAD. More information on [Dummy Load]



DUPLEX CIRCUIT: A circuit that permits transmission in both directions, but not necessarily at the same time.
