 Introduction

The faceplate is a paper template that identifies features that you 
access by pressing specific keys on your telephone. It shows which 
system features have been assigned to your telephone keys.

Your ROLMphone telephone has a separate line key for every 
extension that appears on your telephone. You use the line keys to 
answer and place calls.

Your telephone may have multiple extensions, each of which is 
assigned a separate line key. These line keys can be of different types. 
You will have at least one line key, called the primary line key, which 
corresponds to your extension. The status light that turns on when you 
pick up your handset is next to your primary line key.

You may also have other lines on your phone. You can use both the 
primary line and these other lines to make calls.

Your lines may also appear as lines (called multiple line appearances) 
on other people’s phones. Each person with an appearance of the line 
on his or her telephone has equal access to the line. Also, a call can be 
placed on hold at one telephone, then retrieved at another telephone on 
which that same line appears. See “Hold” on page 2-15 for more 
information.

If you have a multiple line appearance on your telephone, you will 
need to know how to tell if that line is in use. Your telephone tells you 
about the status of a line through the line key’s status light. See “Status 
Lights” on page 1-16 for more information.
