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 pressed.
