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.

fixed feature

❑assignable feature

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:

TYPESHOWN AS:

keypad buttons ❑

dark background buttons with

permanent labels TRANSFER

white background buttons with

changeable labels

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.

Handset Tones

System 25 signals you with tones that are heard through the

handset. The tones and their descriptions are listed below.

PREFERRED ROUTE TONE llllll llllll lllllll lllllll (five short tones)

Your call is waiting in line for the preferred route. You may wait

by staying off-hook or you may hang up and try again later.

Ringing Tones

System 25 signals you with four distinctive rings. The rings and

their descriptions are listed below.

INSIDE CALL

Your call is from a person inside your company.

OUTSIDE CALL llllllllllllllll lllllllllllll (two short rings)

Your call is either from the Attendant or someone outside your

company.

ABBREVIATED ALERT

reminder, a manual signal, or that your voice terminal is in

program mode.

PRIORITY RING llllllllllll lllllllllll lllllllllllllllllllll (two short rings followed

by one long ring)

A call is being set up remotely for this phone via Third-Party

Call Set-Up, a data feature.

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.
