Connecting the 20AT
The 20AT can be connected to most analogue telephone
sockets. If connected to a socket on a private telephone
system check with your System Manager that the socket is
suitable for analogue phones.
– Connect the handset lead to the socket marked
H/SET on the base of the 20AT.
– Connect the phone lead from wall socket to the socket
marked LINE on the base of the 20AT.

INDeX 20AT Telephone User's Guide 38DHB0002UKDU - Issue 1 February 2000
MF & Time Break Recall operation
The 20AT uses MF signalling and TB recall signalling only.
Contact your telephone line provider if unsure of the type
of signalling you should be using.
During a call, phones can use a recall signal to indicate to
the exchange that they are about to send more digits.
REN Values To ring properly when a call arrives all phones draw a
small current from the telephone line. All telephone
devices have a REN value, a measure of how many
'current units' they need to ring properly.
Most telephone lines can provide ringing current for a total
REN of 4. If the total REN of all the devices on the line
exceeds that value, then some of the devices may not ring
when calls arrive.
If it is necessary to connect more devices to a line than it
can support, equipment exists that can increase the total
REN provided by the line. Contact your line provider for
details.
–The 20AT has a REN of 1. It can share the same
telephone line as other telephone devices so long as
the total REN does not exceed that of the line (usually
4).
INDeX standard telephone sockets provide a REN of 2.

20AT Approvals – Page 5
38DHB0002UKDU - Issue 1 February 2000 INDeX 20AT Telephone User's Guide

INDeX 20AT Telephone User's Guide 38DHB0002UKDU - Issue 1 February 2000
INDeX Features
Introduction When used on an INDeX telephone system, the 20AT has
access to a wide range of system features. This section of
the guide covers those features. The 20AT telephone
should only be used in the phone sockets indicated by
your System Manager. It will not work in the sockets used
by INDeX 20DS, 20CC, 2010 and 2030/50/60 phones (and
vice versa).
–Network Features
Your phone system may be part of a network linking
several sites. Wherever possible, it treats network calls
as internal calls and offers the same features. However,
this depends on the type of network link and also the
type of system at the other end of the link (ie. some
links may be to non-INDeX telephone systems).
Dialling Timeout After you start dialling, if you do not dial another digit for
several seconds the system assumes that you have
finished dialling. The system then ignores any further digits
that you dial. By default the timeout is 5 seconds, although
this varies between sites.
Since it is your phone that generates the audible dialling
tones, the system's dialling timeout does not affect calls
connected through the system to services that need to
hear additional MF tones (eg. Voice mail systems, BT star
services, etc).

Telephone Tones & Ringing – Page 9
38DHB0002UKDU - Issue 1 February 2000 INDeX 20AT Telephone User's Guide
Telephone Tones & Ringing
The INDeX 20AT uses various tones and ringing to
indicate calls and other events.
Incoming Calls:
– Repeated Double Ring: External call.
– Repeated Single Ring: Internal call.
During Calls:
–Repeated Single Pip: Another extension is about to
intrude or has intruded on your call.
Outgoing Calls:
–Continuous Tone: Number called unobtainable or set
to no calls. Phone locked, no external calls (or phone is
barred).
–Repeated Tone: Busy number.
–Dial Tone: Dial number.
–Repeated Single Pip: Phone on divert or no calls.
Night Service The system can take different areas into and out of night
service automatically. It does this following timetables
setup by the System Manager. The effects of night service
vary, but typically they are as follows:
–Lines: The system directs calls to a night desk number
or answer phone extension.
–Phones: The type of calls you can make becomes
more restricted, eg. no international or long distance
calls.

Page 10 - Making Calls
INDeX 20AT Telephone User's Guide 38DHB0002UKDU - Issue 1 February 2000
Making Calls
Notes on Making Calls
Your phone allows very simple and quick dialling to make
calls. To simplify dialling further, the INDEX system can
store several hundred speed dials for use by any
extension. It can also store personal speed dials for your
own frequently needed numbers.
–Call Barring
On external calls, the INDeX system may bar you from
dialling particular numbers or types of numbers (e.g.
national, international). Typically, call barring increases
when the system puts the phone's area into night
service. Call barring can also change according to time,
date and day of the week. As the call barring settings
vary for each site, this guide cannot fully detail their
effect.
Making External Calls
"E.T. phone home"
Steven Spielberg 1982.
Redial - Alias:
- Last number redial
- Saved number redial.
The method below uses normal dialling to make external
calls. The system may apply call barring to some or all
external numbers. You can also lock your phone by wrong
passcode entry
(see page 22) .
To dial an external call:
1. Lift the handset and dial 9 (Your System Manager will
inform you if you need to dial a different number)
.
2. If you hear a repeated single pip, the system requires a
PIN code or account code before allowing an external
call
(see page 12) .
3. Dial the telephone number.
4. During the call you can hold or transfer it
(see page 18) .
5. To end the call replace the handset.
To redial last external number used:
1. Lift the handset and dial # to repeat the last external
number used (including speed dials).

Making Internal Calls – Page 11
38DHB0002UKDU - Issue 1 February 2000 INDeX 20AT Telephone User's Guide
Making Internal Calls
"Hello, Neil and Buzz. I'm
talking to you by telephone
from the Oval Room at the
White House, and this
certainly has to be the most
historic telephone call ever
made."
Richard Nixon 1969.
To dial an internal call:
1. Lift the handset and dial the extension or group number.
2. If you hear continuous tone, to leave your number as a
message, dial 1
(see page 14 for full details) .
3. If you hear just ringing, either leave a message as
above or to set a callback, dial 2
(see page 15 for full
details)
.
4. If you hear busy tone, either leave a message or set a
callback as above. Otherwise, to camp on and wait, dial
3
(see page 15 for full details) .
5. To end the call, replace the handset.
Making a Page Call
Page Call - Alias:
- Broadcast
- Zone paging.
You can page any free INDeX 20 Series phone or turret or
group of such phones. They hear the call without doing
anything though you cannot hear them. If wanted, they can
turn the page into a normal call. If the extension you page
is diverting calls, the page also diverts (except group
pages).
To page an extension or group:
1. Lift the handset and dial 7.
2. Dial the extension or group number.
3. If you hear busy or continuous tone, you can use the
same options as for a normal internal call
(see page
14)
.
4. Speak and then replace the handset.
Hotline Operation
Hotline operation allows the phone to automatically dial a
number when left off-hook for a set period. Your System
Manager or maintainer controls the settings for this feature.

Speed Dials, PIN's & Account
Codes
Using Speed Dials
Speed Dials - Alias:
- Abbreviated dialling The INDeX system can store telephone numbers as speed
dials. You can then ring those numbers by dialling the
number of the speed dial store.
–System speed dials: All extensions can use these,
though call barring may still apply. Ask your System
Manager for a list.
–Personal speed dials: You can store up to 10 speed
dials for your own use (see below) .
To use a speed dial:
1. Lift the handset and dial #.
2. Dial the speed dial store number (00 to 09 for personal
speed dials, 100 to 899 and 9000 to 9999 for system
speed dials).
3. If the phone gives a repeated single-pip, it requires a
PIN or account code before allowing the call.
4. Continue as for a normal external call
(see page 10) .
Storing Personal Speed Dials
If external, prefix 9to the stored number, this is the normal
number to seize an external line. Your System Manager
will inform you if you have to add a different prefix number.
To store a personal speed dial number:
1. Lift the handset and immediately dial 0.
2. Broken dial tone: Dial the speed dial store to use (00 to
09).
3. Loud pip: Dial the phone's passcode
(see page 22) .
You will then hear either:-
Continuous tone: Passcode wrong, replace handset.
or
Three soft-tones: Number already set, dial to cancel.
or
Single soft tone: No number set, dial a number and #.
Then replace the handset to finish.
Also see page 7 for storing telephone numbers on your
20AT.

Forced Account Code Entry – Page 13
38DHB0002UKDU - Issue 1 February 2000 INDeX 20AT Telephone User's Guide
Forced Account Code Entry
A repeating single-pip when making an external call may
indicate that you must dial an account code before
continuing (check with your System Manager). If so, the
system checks the code you dial against its list of codes
before allowing the call. The system can store up to 200
12-digit codes. Ask your System Manager for a list of valid
codes.
To enter a forced account code:
1. Dial an account code
2. If you make a mistake, dial and try again.
3. Then dial the external number required.
Forced PIN Code Entry
A repeating single-pip when making an external call may
indicate that you must dial a PIN code before continuing
(check with you System Manager). If so, the system checks
the code you dial against its list of codes before allowing
the call. The PIN code you use also sets your call barring
and phone status for that call. The system stores up to 200
PIN codes of up to 6 digits. Ask your System Manager for a
list of valid PIN codes.
To enter a PIN code:
1. Dial your PIN code
2. If you make a mistake, dial and try again.
3. Continuous tone: Code not recognised, end the call.
or
Silence: Code accepted, continue the call as normal.
Roaming PINS
Roaming PINs - Alias:
- Mobile access. You can use a PIN code and its associated phone & call
barring settings to override the restriction on another
normal phone. Note that when you do this, the system
automatically forces the call to be external.
To use a roaming PIN:
1. Lift the handset and dial 6.
2. Repeated single pip: Dial your PIN code. If you make a
mistake, dial and dial the number again. You will hear
either:-
3. Continuous tone: Code not recognised, end the call.
Or
Silence: Code accepted, continue the call as normal.

Page 14 - Busy or Unanswered
INDeX 20AT Telephone User's Guide 38DHB0002UKDU - Issue 1 February 2000
Busy or Unanswered
If Busy or Unanswered
Your phone provides several methods for contacting an
extension that is busy, not answering or set to no calls.
These option work for normal, page and diverted calls.
–Leave a Message:
Lights the lamp of the extension called. That extension
also stores (and displays if a display phone) your
number as a message to reply.
–Callback:
Rings your phone when the extension called becomes
free or is next used.
–Camp On:
Flashes the lamp on the extension called to notify them
that you are waiting. It also stops other calls interrupting
you.
Leaving a Message
The system can store your extension number as a
message for another extension to call you. If that extension
has a message lamp, the system also lights the lamp
(supported on all INDeX 20 Series phones plus some
standard telephones)
. If your call was diverted, the
message goes to the extension from which you were
diverted.
To leave a message:
1. Dial 1.
2. The system ends your call (unless the extension called
has already reached its limit of five stored messages).
3. Replace the handset.

Arrange a Callback – Page 15
38DHB0002UKDU - Issue 1 February 2000 INDeX 20AT Telephone User's Guide
Arrange a Callback
Callback - Alias:
- Ringback.
- Call back when free.
- Call back when next used.
If the extension you called is busy or does not answer, you
can set a callback. When that extension becomes free or
is next used, your phone rings. When you answer, the
other extension rings. After setting a callback you can
make other calls, the callback will not take place if you are
busy. You can only arrange one callback at a time.
The Ringer Timeout sets how long a callback rings at your
extension before cancelling
(see page 22) . The system
also cancels callbacks that have not taken place after a
period set by the System Manager (the default is 2 hours).
To arrange a Call Back:
1. Dial 2.
2. The system ends your call unless you already have a
callback set.
3. Replace the handset.
Camp On and Wait
Camp On - Alias:
Wait on busy. If the extension you call is busy, you can 'camp on' and
wait. This flashes the lamp on the busy extension if it is an
INDeX phone. If it is an INDeX display phone, the display
shows your name and number. While camped on, you
cannot make or receive any other calls.
To Camp On to a busy extension:
1. Dial 3 and wait.
Do not replace the handset as this ends the call and
the camp on.

Diverting Calls
Using Diverts
Divert All - Alias:
- Manager transfer.
- Secretary filter.
Divert No Answer - Alias:
- Divert no reply.
No Calls - Alias:
- Do not disturb.
Your phone can have diverts for different situations, i.e.
when busy, not answering or to divert all calls. You can
also select no calls
(which uses the Divert All number if
set)
.
–Divert on busy: Calls divert when your phone is on a
call. When set, callers cannot set a callback or camp on
