Strata CTX DKT3000/2000-Series Digital Telephone October 2002 85
Centrex Application A
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’s extension can be three or four digits. It is, therefore, possible to match a station’s extension
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 pre-programmed Flexible Button on your
telephone, instead of dialling 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.
