ROLMphone 300/600 User Guide

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.)

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.

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.

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.
