Centrex Application
B
Your system may be equipped with the Centrex Application, which enhances its feature
capability when installed behind a Centrex or PBX system.Your telephone may have access to
one or more of the enhanced Centrex features listed below.
Flexible Directory Numbering
A station [PDN] can be three or four digits. It is, therefore, possible to match a station [PDN]
and Centrex line extension number. Dial the entire station number when indicated.
Note
Some access code numbers may have been changed to avoid system numbering plan
conflicts.
Centrex Feature Buttons
You can access some Centrex features by pressing a preprogrammed flexible button on your
telephone, instead of dialing a Centrex access code. The Centrex access code, including the
necessary flash and/or pause sequence, is activated when the button is pressed. See your
Centrex or PBX operations manual for specific details.
Ringing Repeat
The distinctive ring patterns available in your Centrex system are automatically repeated with
your electronic telephone enabling you to answer appropriately for either outside, inside or
callback calls.
