COMSPHERE 3800 Series Modems

DCE	The equipment (Data Communications Equipment or Data Circuit Terminating
	Equipment) that provides the functions required to establish, maintain, and end a
	connection. This equipment also provides the signal conversion required for
	communication between the DTE and the telephone line. A modem is a DCE.
DCP	Diagnostic Control Panel. The face of the modem that continuously provides status
	information about the modem’s operation and allows an operator to manage its operation.
	This is a generic term used for both the standalone and carrier-mounted models. See
	SDCP.
demodulation	The process of recovering data from a modulated carrier wave.
dial command modifiers	A modifier used in the dial string that instructs the modem how to process a dialed
	telephone number.
dial line	A communications circuit that is established by a switched circuit connection in the dial
	network.
dial network	See PSTN.
Dial Standby	A function available when the modem is operating in Dial Backup mode, allowing the

DTE	The equipment (Data Terminal Equipment), such as a computer or terminal, that
	provides data in the form of digital signals.
edit area	A temporary work area used to view and change configuration options from the DCP
	without impacting modem operation. The edit area can be loaded from one of five
	configuration option areas, Active (Operating), Active (Saved), Customer 1, Customer 2,
	or Factory.
EIA	Electronic Industries Association. This organization provides standards for the data
	communications industry.
EIA-232-D	An Electronic Industries Association’s standard defining the 25-position interface
	between data terminal equipment and data communications equipment.
EIA RS-366-A	An Electronic Industries Association’s standard defining the 25-position interface
	between data terminal equipment and data communications automatic calling equipment.
