Data Dial Code (DDC)

When your System 25 was installed, Data Dial Codes (DDCSs) were assigned to data terminals. If you have a data terminal associated with your System 25, you will receive separate information regarding its use.

Personal Dial Code (PDC)

Personal Dial Codes (PDCs) were assigned to telephones. In most cases, your PDC is your extension number. If a telephone is shared by two or more people, each person may have been assigned their own “floating” extension number (FPDC).

Additional Information

See your System Administrator if you have any questions or would like additional information about your System 25 features.
