Introduction

This guide describes the features available to you from AT&T

System 25 through a single-line voice terminal. It also provides

instructions for using those features. For your convenience, the

features are arranged in alphabetical order. The manual also

includes certain reference information you may want to review at

a future time.

Your voice terminal is ready to use as soon as it is connected to

System 25. So as you learn to use the features, you can make

and receive calls with your voice terminal just as you would with

an ordinary telephone.

System 25 supports both Touch-tone and Rotary sets. However,

if you have a rotary set, you will

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 single-line voice terminal. In

this guide, they are identified at the top of the page by a box

with a check. Assignable features are distributed by your

System Administrator and are identified by an empty box.

The Switchhook (Recall, Flash)

The switchhook is the button(s) held down by the handset when

it rests in the handset holder on your voice terminal. Some

System 25 features require that you use the switchhook to signal

the system.

When you are instructed to press the switchhook, press the

button(s) down as far as it will go for approximately 1/2 second

and then release it. If the switchhook is released too soon, the

signal will not work. If you hold the switchhook down for too

long your call will be disconnected.

NOTE: If you have a [RECALL] or [FLASH] PI button on your

voice terminal, you can press it instead of the

switchhook. These buttons send a timed signal to the

system, so disregard how long you hold down the

button.

If you want to hang up and place. another call right

away, be sure to hold down the switchhook for more

than two seconds. Do not use the [RECALL] or [FLASH]

button to disconnect the call.

would like additional information about your System 25 features.

Single-Line Features

Account Code Entry

For bookkeeping purposes, your System Administrator may

assign account codes to use with certain calls. If you are required

to use the account codes for outgoing calls, your System

Administrator has administered the Forced Account Code Entry

feature, and you need to dial an account code before placing an

outside call. If this feature is not mandatory, you may still

optionally use the Account Code Entry feature.

See your System Administrator to verify the types of calls for

which you must enter an account code if the Forced Account

Code Entry feature has been activated.

You may also want to use the Call Accountability feature before

or after entering the account code. For more information, see

● the entry for “Call Accountability” on page 7.
