Introduction
This guide describes how users of multiline voice terminals may
use System 25 features. The voice terminals that can be used
with this guide are shown on pages 2 and 3.
Features
Your AT&T System 25 has two types of features, fixed and
assignable, that transform your telephone into a voice terminal.
Fixed features are available on every multiline voice terminal.
Assignable features are assigned by your System Administrator.
In this guide, fixed features are identified by a check in the box
at the top of the page.

If you need an assignable feature, see your System
Administrator. As a reminder, you may wish to check the boxes
of the assignable features you have.
Buttons
There are three types of buttons on most multiline voice
terminals. Each is represented in a special way in this guide:

Each Multiline voice terminal has at least two System Access
buttons that can be used to place and receive calls. From these
buttons you can also gain access to outside lines and system
features. On most terminals, these buttons are located in the
upper left portion of the faceplate, and are labeled with your
PDC (extension number). Unless otherwise noted, you must use a
System Access button for the procedures described in this manual.
Line Selection
If your voice terminal automatically selects a line when you lift
the handset to place a call, you have the option “prime line
preference.”
If your voice terminal automatically selects the
ringing line when you lift the handset to answer a call, you have
the option “ringing line preference. ”
Throughout this manual, it has been assumed that you have
both ringing line preference and prime line preference (on a
System Access button). If you do not have these options, the
appropriate line (button) must be manually selected at the beginning of
most procedures.
Multiline Voice Terminals
The voice terminals shown below and on the following page are
some of the terminals that are supported by System 25. You can
use this guide with any of these voice terminals.

Lights
A steady red light identifies the line you are using or the
line you will be using when you lift the handset.
A steady green light indicates that a line or feature is in
use.
A slow flashing green light indicates an incoming call.
A fast winking green light indicates a call on hold. (An
intermittent winking green light indicates a call held
temporarily while being transferred or conference.)
DDCs and PDCs
When your System 25 was installed, Data Dial Codes (DDCs)
were assigned to data terminals and Personal Dial Codes (PDCs)
were assigned to voice terminals. In most cases, your PDC is
your extension number. If a voice terminal is shared, each
person may have been assigned their own "floating" PDC.
For Additional Information
See your System Administrator if you have any questions or
would like additional information about your System 25 features.

Call Coverage
❑
If your calls are covered by someone else, unanswered calls will
start ringing at the covering terminal after a preset number of
rings. However, if you are busy on another line, calls will go to
coverage after one ring.
If you have a button, you may use it to tell
System 25 that you do not want to be disturbed. When this
feature is activated, most calls will be sent immediately to the
covering terminal (although you may hear a single ring for each
call, to remind you that the feature is still on).
Your System Administrator determines the number of rings
before unanswered calls are sent to coverage, and whether users
of will receive a single ring reminder when the
feature is activated.
