Feature Keys
Feature keys give you access to CBX system features
such as Hold, Transfer, Mailbox, and Program. Press
the key labeled with the feature name to gain access
to the feature. You can also dial feature access codes
to gain access to features. (See “Feature Access
Codes” on page 1–17.)
Note
The labels used in this guide to indicate feature names
on keys are the defaults that come with your system.
However, your CBX system administrator can
configure them differently to suit your company’s
requirements.
Class of Service
Each telephone in your CBX system has a class of ser-
vice (COS) that specifies the features available on that
telephone. Therefore, you may find that some features
included in this guide are not available on your tele-
phone. Consult your CBX system administrator for
information on your telephone’s class of service.
Some of the telephones in your system may be set up
to use one class of service (the primary) during nor-
mal business hours and then automatically change to
a more limited one (the secondary) during non-busi-
ness hours. If so, the features you can use may vary,
depending on the class of service in effect at the time.
Personal Identification Number (PIN)
A personal identification number (PIN) enables you
to use another telephone within your company to gain
access to the features of your own telephone. You
may also need a PIN to be able to dial an outside num-
ber.
Ask your CBX system administrator whether you
have been assigned a PIN. Also see “External Calls”
on page 2–10, “PIN Authorization Features” on page
7–14, and “Forced Authorization” on page 7–18.
