Auto Dial button
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 Equipment
feature button and Programmable button.
Auxiliary equipment
Telecommunications equipment (other than MLS-
and MLC-model telephones) that can be connected
to the equipment controller. Auxiliary equipment
includes industry-standard devices that can
connect directly to the public telephone network
(such as standard phones or fax machines) as well
as devices that require the interface provided by
the equipment controller (such as a loudspeaker
paging system).

Backplane
The bottom and rear portion of the plastic housing
that makes up a carrier. The backplane distributes
power to the premises equipment, and has slots
where the modules are installed.
Backup programming extension
A second extension from which you can program
premises equipment, using the phone connected to
extension jack 11 on your equipment controller. See
also Primary programming extension.
Button-Down Mode
A system-wide setting that causes incoming calls
on secondary lines to flash, but not ring. A user
must press the line button down to pick up the call.
This feature enables the equipment to imitate the
way lines ring at extensions on key telephone
systems like the 1A Key System.
Call coverage
An arrangement that lets a receptionist or a person
at another extension answer a call when the dialed
extension is busy or not answered. Call coverage
may be provided centrally by a receptionist (using
default equipment settings), locally by a person at
another extension (requiring secondary line
assignments), or using Centrex coverage services
(such as call forwarding or voice mail). In addition,
answering machines may be installed at key
extensions to take messages when a person is not
available to take calls.

data fields such as call type, date, time, called
number, and call duration. See also Call report.

also Intercom Calling button.

A feature available from your Centrex system or
from the equipment controller that lets you control
telephone use at specific extensions.

Molded plastic housing, made up of a backplane
and cover, which holds equipment controller

primary carrier and can be expanded to include the
expansion carrier.
Centralized Telephone Programming
A method of telephone programming that lets you
program individual extensions in the system from an
MLS-34D or MLS-12D phone at extension jack 10 or
extension jack 11. Centralized Telephone
Programming is an alternative to Extension
