3-2 Using the Equipment
A programmable telephone button that lets you dial a series
of digits simply by pressing that button. An Auto Dial button
can be used to store a Centrex feature code or a telephone
number so that it can be dialed with one touch. See also
Programmable button.
A short code (or "Centrex extension ID") that can be used to
dial another extension within the Centrex system. Typically,
this is the last digits of the Centrex telephone number.
The total block of Centrex lines you subscribe to—all or some
of which may be connected to the equipment controller for
your system—together with the Centrex services associated
with those lines. See also Premises equipment.
The phone number that outside callers dial to reach an
extension within the Centrex system.
A call made from an extension inside the Centrex system to
another extension inside the Centrex system, using the
Centrex extension number.
A call made from outside the Centrex system to an extension
within the Centrex system, or from inside the Centrex system
to a number outside the Centrex system. If your Centrex
system uses a dial-out code (usually a "9"), you must dial it
before you dial an outside telephone number.
The AT&T equipment controller and MLS- and MLC-model
telephones that you purchased as part of your system, plus
all other telecommunications devices that are connected to
your equipment controller. For purposes of this guide,
premises equipment does not include any equipment that
connects directly to Centrex lines without going through the
equipment controller. See also Centrex system
A telephone button that can be set up to access a feature.
On MLS- and MLC-model phones, programmable buttons
can be used as Auto Dial buttons (for one-touch dialing of
Centrex feature codes or telephone numbers) or equipment
feature buttons.
An equipment feature that sends a timed switchhook flash to
let you access a Centrex service. (Use Recall only on an
outside or inside call; using Recall on an intercom call
disconnects the call.)
