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.

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.
