Paradyne 3800 manual Erasable programmable read-only memory

Glossary

EPROM	Erasable programmable read-only memory.
error control	An algorithm used to correct data transmission errors.
escape sequence	Default setting is +++. This sequence lets you switch your modem from Data mode to
	Command mode.
extended result codes	An asynchronous message (in either numbers or words) that includes VF data rate and
	error control information the modem sends to the DTE after executing or trying to
	execute a command.
fax modem	A modem capable of emulating some features of a fax machine. Working under the
	control of fax software, a fax modem can communicate with a fax machine or with
	another fax modem.
fax software	A program or system of programs installed on a computer that allow a fax modem to
	send and receive facsimile images.
FCC	Federal Communications Commission. Board of Commissioners that regulates all
	interstate and foreign electrical communication systems that originate from the United
	States.
full-duplex	Simultaneous, two-way communications.
function key	One of three keys on the DCP that allows you to select or increment an LCD entry.
	Function keys are labeled F1, F2, and F3.
Group III	A fax standard that specifies a rate of transmission of about one page per minute.
half-duplex	Two-way data communications allowed in only one direction at a time.
handshaking	The exchange of predetermined codes and signals (tones) to establish a connection
	between two modems.
HDLC	High-Level Data Link Control. A communications protocol defined by ISO.
hidden choice indicator	A symbol appearing in the upper right-hand corner of the LCD, indicating that more
	selections are available than what appears on the LCD.
host	A computer attached to a network that shares its information and devices with the rest of
	the network.
Hz	A unit of frequency (hertz) that equals one cycle per second.
idle	A state in which the modem’s operating parameters can be modified or commands can be
	issued to the modem using either AT commands or the DCP.
ITU-T	The Telecommunications Standardization Sector of the International
	Telecommunications Union, an advisory committee established by the United Nations to
	recommend communications standards and policies. Before March 1993 it was called
	CCITT.
ITU-T V.17	A fax communications standard for modems operating half-duplex with synchronous
	data at 14,400 bps.
