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.

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.

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.

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).
