DTMF
See dual tone multifrequency (DTMF).
dual in-line package (DIP) switch
A small switch, usually attached to a printed circuit card, in which there are only two settings: on
or off (or 0 or 1). DIP switches are used to configure the card in a semipermanent way.
dual language greetings
The capability of INTUITY AUDIX users to create personal greetings in two different languages—
one in a primary language and one in a secondary language. This capability exists when the mul-
tilingual feature is turned on, and the prompts for user mailboxes can be in either of the two lan-
guages.
dual tone multifrequency (DTMF)
A way of signaling consisting of a pushbutton or touch-tone dial that sends out a sound consisting
of two discrete tones that can be picked up and interpreted by telephone switches.
E
EIA interface
A set of standards developed by the Electrical Industries Association (EIA) that specifies various
electrical and mechanical characteristics for interfaces between electronic devices such as com-
puters, terminals, and modems. Also known as
RS-232 .
ELA
See Enhanced-List Application (ELA) .
electronic mail
See e-mail.
electrostatic discharge (ESD)
The discharge of a static charge on a surface or body through a conductive path to ground, ESD
can damage integrated circuits.
e-mail
The transfer of a wide variety of message types across a computer network (LAN or WAN). E-mail
messages may be text messages containing only ASCII files or may be complex multimedia mes-
sages containing embedded voice messages, software files, and images.
enabled/disabled
The state of a hardware device that indicates whether it is available for use by the Lucent I
NTUITY
system. Devices must be equipped before they can be enabled (made active). See also
equipped/unequipped.
endpoint
See fax endpoint.
enhanced call transfer
An INTUITY AUDIX feature that allows compatible switches to transmit messages digitally over the
BX.25 (data) link. This feature is used for quick call transfers and requires a fully integrated digital
switch. Callers can only transfer to other extensions in the switch dial plan.
Enhanced-List Application (ELA)
An I
NTUITY AUDIX option that facilitates message delivery to large numbers of recipients. There
can be up to 100 enhanced lists per system, each of which can contain up to 1500 addresses.
