Centrex
extension
number
Centrex system
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.
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).
Telephone services that your local telephone company
provides from a Central Office (CO) located outside your
business premises, including Centrex lines connected to the
equipment controller and the features available on those
lines. (Your telephone company may call Centrex by another
name.)
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.
