INTRODUCTION
Overview
As your System 25’s attendant, you are often the first
person whom outside callers speak to when they dial your
organization.
You are well equipped to handle these and any
other types of calls. Your Switched Loop Attendant Console
(SLAC) provides the same useful features that other voice
terminals in the system have. In addition, your console has
special capabilities that enable you to perform the following
attendant tasks quickly and efficiently:
Answer or place calls, then extend them to other
stations
Visually identify the source of calls
Prevent calls. from being lost or ignored
Set up outgoing trunk calls
Alert system users to messages waiting
Establish conference calls
Monitor system alarms.
This guide contains the operating procedure for every
feature that can be used at your console. System 25 has
two kinds of features, fixed and assignable, that transform a
telephone into a voice terminal. A fixed feature is one that is
standard (that is, built-in or ready-to-use) and does not have
to be activated by the System Administrator. An assignable
feature is one that must be activated by the System
Administrator before you can use it.
Continued
1

Overview (Contd)
In this guide, fixed features are identified by a preprinted
checkmark in the box at the beginning of each procedure.
Assignable features that the attendant always has are
marked in the same way.
The boxes for other assignable
features are blank; as a reminder, you may wish to check
the boxes of the additional assignable features you have.
Discuss the assignable features you need with your System
Administrator.
A System 25 can have either one or two Attendant
Positions. At any position, the basic SLAC can be used
alone or with a Direct Extension Selector Console. The size
and needs of your company will determine whether you have
the basic SLAC or the SLAC + Selector Console combination.
This user guide provides instructions for both arrangements.
Your SLAC has three types of buttons. Each type is
represented in a special way in this guide:

Overview (Contd)
In addition to the Introduction, this user guide has two main
sections, Attendant Features and Standard Multiline
Features. The first section contains the procedures that you
will be using most of the time in your duties as attendant to
answer, originate, and extend calls. It also includes
procedures for using features that are unique to your
attendant console.
The second main section contains
additional procedures that are available to you and all other
voice terminal users.
Use the Table of Contents near the
front of the guide to find the procedures you need.
The Glossary at the back of this guide has feature
descriptions and definitions of many terms, abbreviations
and acronyms used in the procedures. The Quick Reference
Card inside the back cover contains feature access codes
and can be used for listing various optional dial codes.

Support Information
Before getting into the specific procedures, you should
become familiar with the following console features that
have general application.
Handset Tones
System 25 signals you with several tones heard through the
handset. The tones and their descriptions are listed below.
• Dial Tone (a continuous steady tone) -
You can dial.
• Confirmation Tone (three short tones) - Your action
has been accepted. Proceed to the next step.
• Ringback Tone (slow repeating on/off tone) - The
number you dialed is ringing.
• Busy Tone (repeating on/off tone)
- The number you
dialed is busy.
• Fast Busy Tone (fast repeating on/off tone) - The
number or access code you dialed was busy,
misdialed, or restricted.
• Preferred Route Tone (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.

Support Information (Contd)
Ringing Tones
System 25 signals you with four distinctive rings. The rings
and their descriptions are listed below.
•
•
•
•
Inside Call (one long ring, repeated) - Your call is from
a person inside your company.
Outside Call (two short rings, repeated) - Your call is
from someone outside your company.
Abbreviated Alert (one short burst of ringing) - Either a
new call has entered the queue, or you have received
a busy-to-idle reminder, a held call reminder, or a
manual signal.
Priority Ring (two short rings followed by one long
ring, repeated)
- A call is being set up remotely for
this phone via Third Party Call Setup, a data feature.
Selector Console Operation
The Selector Console allows
pressing one or two buttons
you to call an inside number by
rather than by dialing several
digits. The bottom row of buttons (except for the rightmost
position, which is for testing the console) is used for
selecting the “hundreds group”
of each extension number.
These seven Group Select buttons are administered and
labeled in accordance with the system’s numbering plan.
The 100 Direct Extension Selection (DXS) buttons above the
Group Select row have fixed numbering from 00 through 99
and are used to select specific extension numbers within a
hundreds group.
For example, to call extension 273, you
press the 200 Group Select button on the bottom row
followed by the 73 DXS button; to call 4519, you press 4500
and 19.

Support Information (Contd)
Loop Buttons
The voice communications paths between your console and
the system switch are called loops. Your Switched Loop
Attendant Console gets its name from the system’s ability
to hold incoming attendant-bound calls in a queue and
switch them to the console by way of these voice loops.
Calls are directed to the console in a predetermined,
prioritized sequence.
The console receives the calls one at a
time; while you are busy with a call, any other calls will wait
in the queue until you are ready for the next one.
You will answer all incoming calls at the five <LOOP>
buttons on the upper left side of the console. The loops
also carry all calls placed from the console, although other
buttons (such as those on the Selector Console) may be
used to start the calls.
Automatic Loop Selection
Whenever an incoming call is ringing, lifting the handset
(going off-hook) automatically connects you to the caller. If
your console is idle and you want to place a call, lifting the
handset automatically gets dial tone for your call at one of
the <LOOP> buttons.
In a few situations, you may have to press a <LOOP>
button when you answer or place a call. The console
procedures will provide specific instructions when this is
necessary.

Console Buttons and Lights
Continued7

Support Information (Contd)
Lights
A red l-use light and a green status light adjacent to each
<LOOP> button provide information about the loop
terminated on that button.
A steady red light identifies the line you are using or will be
using when you lift the handset. Only one red loop light is
ever lighted on the console. A steady green light indicates
that a loop or feature is in use. A flashing green light at a
<LOOP> button indicates an incoming call. When the
incoming call is answered, the flashing green light changes
to steady.
If you put a call on hold, the green light starts winking. As
a reminder, the wink rate increases when a call has been on
hold longer than a pre-administered period. The special
conference hold condition is indicated by broken fluttering.
Status light rates:
• Flash - Slow on/off; repeated.
• Wink - Long on/short off; repeated.
• Broken flutter - Fast on/off for 1/2 second, then dark
for 1/2 second; repeated.
Most feature buttons have no lights, but some have either a
red and a green light or a single green light. The red lights
are inoperative on feature buttons.
The lights of the Selector Console enable you to monitor the
on/off-hook status of system stations. If you press a Group
Select button while you are
“on-hook” at the SLAC, the
DXS lights of any off-hook stations in that group will turn
on steadily.
Continued
8

Support Information (Contd)
The Selector Console lights can also provide you with other
information about activity at system stations:
• A call parked at a Call Park DXS button will cause the
associated light to turn on steadily.
• Any call from an inside station to the console is
indicated by a flashing DXS light; however, incoming
call information is presented in a much more
convenient form by the console display, which is
described next.
Call Information Display
The console’s built-in display provides visual data about
incoming and outgoing calls. The display can present two
different screens of information in the window at the top of
the console. Screen 1 appears automatically and contains
primary call data such as the following:
• Extension numbers and names of inside parties
• Trunk identification for calls from outside -
• Digits dialed on outgoing trunk calls
• Called party identification on coverage calls
• Number of calls waiting to be serviced.
To see Screen 2, you must press the <SCROLL> button.
Screen 2 contains secondary information such as the source
of a coverage call and the reason it was redirected. Screen
2 is also useful when you are in the process of extending an
incoming call and want to see both calling and called party
data. If Screen 2 does not appear when you press
<SCROLL>, it has no information available for viewing.

Support Information (Contd)
Pressing the <INSPECT> button puts the display into the
Inspect mode, in which you can check the information
associated with specific buttons. Refer to the Inspect
feature for details.
The Thumb-wheel Contrast control adjacent to the screen
allows you to adjust the visibility of the display under
various lighting conditions.
The procedures in this guide include typical call information
displays.
Symbols Used in Displays
Two groups of symbols provide specific information about
incoming calls.
The following redirection symbols generally appear on the
left side of the display (Screen 1).
>—
}—
&—
A coverage call has been directed to the
console.
A call is returning to the console from a
station that is busy or that does not answer;
this symbol can also indicate a call returning
after being parked but not picked up.
The “start/split” condition has been activated
in order to extend a call; that is, the
<START> button has been pressed to split a
call (put it on temporary hold).

An incoming call is placed to an Incoming
Calls Group, of which you are a member.
A call is forwarded to the console by use of
the Call Following feature.
A parked call is returning to the console
because it was not picked up.
Console Queue Status
The number of calls waiting in the queue is shown on the
right side of the display (Screen 1). If between one and nine
calls are waiting for service, the actual number appears. A
queue of ten or more calls is indicated by “!”.
DDC's and PDC's
When your System 25 was installed, Data Dial Codes (DDC's)
were assigned to data terminals, and Personal Dial Codes
(PDC's) 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 his or her own
“floating” PDC.

ATTENDANT FEATURES
Answering Calls
Only one call can come into your console at a time; calls are
held in a queue at the system switch until you, or the other
attendant, can handle them. Your console is available to
incoming calls only when you have no other active calls and
at least one loop is idle.
You answer all incoming calls at one of the five <LOOP>
buttons on the upper left face of the console. (The system
selects <LOOP> buttons in a rotating sequence for
receiving calls. ) When an incoming call rings, the green light
next to the selected <LOOP> flashes.
Answering a Call
1. Lift the handset (it is not necessary to press the
incoming call button).
● The green light changes from flashing to steady.
2. Talk to the caller.
Typical Displays for Incoming Calls:
● A Direct Inward Dialing (DID) call is directed to
extension 2085, which is assigned to your console.
Three calls are
waiting in the attendant queue.

Attendant Message Waiting
You can use a Message light to notify voice terminals of
waiting messages. When you call a voice terminal, the
status light next to your <ATTENDANT MESSAGE
WAITING> button will have the same on/off condition as
the Message light on the voice terminal you call. Most
voice terminals have a button associated with their Message
light so that users can turn off their own lights. If a voice
terminal does not have this button, you must turn off the
Message light from your console.
