Introduction
Using this Guide This guide is for the DT1 phone used on the INDeX telephone system.
To check what type of phone you have, look at the label on its base.
Whilst this guide covers all the features supported by the DT1, your DT1
may not be able to use of them. If unsure of which features you can use,
contact your System Manager.
–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 type of system at the other end of the link.
Further Help
"Why don't you do
something to help me?"
Stan Laurel 1947.
In all instances, first seek help from your System Manager. They will
seek further assistance from your system's Maintainer if necessary.

This guide is also available in several computer formats (eg. Windows
Help, Adobe Acrobat) and as part of a computer based training
program. Contact your System Manager to obtain copies or download
them from the internet site (http://www.sdxplc.com).

DT1 Phone Features
Introduction to the DT1
"When at last this little
instrument appeared,
consisting, as it does, of
parts everyone of which is
familiar to us, and capable of
being put together by an
amateur, the disappointment
arising from its humble
appearance was only
partially relieved on finding
that it was really able to talk."
James Clerk Maxwell, "The
Telephone" 1878
The diagram shows the main features of a DT1 phone.
The system supports a wide range of other phone types for different
applications and uses (see "Glossary" on page 30).
Handsfree (Speaker) & Answer Release
On all DT phones you can dial and hear the call progress without using
the handset (known as "on-hook dialling").
When answered, on the DT1 you can continue the call without using the
handset, ie. handsfree. You can switch between handsfree and handset
during a call.
On all the DT phones, pressing the ANSWER RELEASE key has the
same effect as lifting or replacing the handset.

Making Calls
Notes on Making Calls
Your DT1 phone allows very simple and quick dialling to make calls. To
simplify dialling further, the system can store several hundred speed
dials for use by any extension (see page 10). You can also store your
own frequently needed numbers as speed dials.
Call Barring
The system can bar you from dialling particular numbers or types of
numbers (eg. 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 detailed their effect.
Making External Calls
"E.T. phone home" Steven
Spielberg 1982.
Redial - Alias:
- Last number redial
- Saved number redial.
The system may apply call barring to some or all external numbers(see
Call Barring above). You can also lock you DT1 (see page 25) or bar it
by wrong passcode entry (see page 24).
To dial an external call:
1. Dial 9(Your System Manager will inform you if you need to dial a
different number).
2. If the DT1 gives three tones, it requires either a PIN or account code
before allowing the call.
3. Dial the external telephone number.
4. When answered, either pickup the handset or continue the call
handsfree.
5. During the call you can do several actions;
– Park, hold or transfer the call (see page 18).
– Perform various other actions (see page 14).
6. To end, dial ANSWER RELEASE or replace the handset.
To redial the last external number used:
1. Dial REDIAL to repeat the last external number used (including
speed dials).

Making Calls – Page 9
INDeX - DT1 Phone Guide 38GDE00001SAC - Issue 4 (January 1999)
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.
The method below uses normal dialling to make internal calls.
To dial an internal call:
1. Dial the extension number. A triple-tone means that the extension
called is diverting calls to an external number (DT-3/4/5 phones).
2. If unanswered, the DT1 provides options to wait or notify the
extension you called (see page 12).
3. If answered, either pickup the handset or continue the call
handsfree. During the call, the DT1 provides a range of further
actions (see page 14).
4. To end, dial ANSWER RELEASE or replace the handset.
Making a Page Call
Page Call - Alias:
- Broadcast
- Zone paging.
You can page any INDeX DT or TT phone 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 (see page 16). If the
phone paged is diverting calls, the page also diverts (except group
pages).
To page an extension or group:
1. Dial FEATURE 4.
2. Pickup the handset or continue handsfree.
3. Dial the extension or group number.
4. If the extension is busy or set to No Calls, you can wait or leave a
message (see page 12).
5. Speak and then dial ANSWER RELEASE.

Page 10
INDeX - DT1 Phone Guide 38GDE00001SAC - Issue 4 (January 1999)
Speed Dials, PIN's & Account Codes
Using Speed Dials
Speed Dials - Alias:
- Abbreviated dialling
The system can store telephone numbers in speed dial stores. You can
then ring those numbers by dialling the number of the speed dial store.
–System speed dials: All extensions can use these, though still
subject to call barring. 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. Dial SPEED DIAL and then the speed dial store number (00 to 09
for personal speed dials and 100 to 999 for system speed dials).
2. If the DT1 gives three tones, it requires either a PIN code or account
code before allowing the call, check with your System Manager.
3. Continue as for a normal external call (see page 8).
Storing Personal Speed Dials
If external, prefix a 9to the speed dial 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 before external numbers
To store a personal speed dial number:
1. Without lifting the handset, dial FEATURE .
2. Short-chirp: Dial SPEED DIAL.
3. Double-tone: Enter the DT1's 4-digit passcode. If you make a
mistake dial to restart entry.
4. Double-ring: Passcode not accepted. Dial the passcode again or
dial FEATURE to stop.
5. Single Ring: Passcode accepted. Dial the number of the personal
speed dial store to use (0 to 9).
6. Double-ring: The DT1 has a number set. Either dial to cancel it or
dial a new number (prefixed with a 9if external) followed by #.
7. Single-ring: The DT1 has no number set. Dial a new number
(prefixed with a 9if external) followed by #or dial FEATURE to stop
8. Deep double-ring: Number entered invalid. Repeat the step above
or dial FEATURE to stop.
9. Short-chirp: Select a feature or dial FEATURE to finish.

Speed Dials, PIN's & Account Codes – Page 11
INDeX - DT1 Phone Guide 38GDE00001SAC - Issue 4 (January 1999)
Forced Account Code Entry
Account Code:
The system can store up to
200 12-digit codes. Ask your
System Manager for a list of
valid codes.
Three tones when making an external call may indicate that you must
enter an account code to continue. Check with your System Manager. If
so, the system checks any code against its list of codes before allowing
the call. You can also enter an account code at any time during a call
(see page 14).
To enter a forced account code:
1. Dial an account code. If you make a mistake, dial FEATURE 64to
restart entry.
2. When you have entered the full code, dial FEATURE #.
3. If you hear the three tones being repeated, the system did not
recognise the account code. Either repeat the steps above or dial
ANSWER RELEASE to end your call.
4. If the tones stop repeating, you can continue the call.
Forced PIN Code Entry
PIN Codes:
The system stores up to 200
PIN codes of up to 6 digits.
Ask your System Manager
for a list of valid PIN codes.
Three tones when making an external call may indicate that you must
enter a PIN code to continue. Check this with your System Manager. If
so, the system checks any code against its list of codes before allowing
the call. The PIN code you use sets your call barring and phone status
for that call.
To enter a PIN code:
1. Dial your PIN code. If you think you have made a mistake, dial to
delete the last digit entered.
2. When you have entered your PIN code, dial #.
3. Continuous Tone: The system did not recognise the code. Dial
ANSWER RELEASE to end your call.
4. If the three tones stop repeating, you can continue the call as
normal.
Roaming Pins
Roaming PINs - Alias:
- Mobile access. You can use PIN codes to override the call barring settings of the phone
from which you dial. Note that the system automatically prefixes digits to
force the call externally.
To use a roaming PIN:
1. Dial #. The DT1 gives three tones. Enter your PIN in the same way
as for forced PIN entry (see "Forced PIN Code Entry" above).

INDeX - DT1 Phone Guide 38GDE00001SAC - Issue 4 (January 1999)
Busy or Unanswered
If Busy or Unanswered
Your DT1 phone provides several methods for contacting an extension
that is busy, not answering calls or set to no calls. These options work
for normal, page and diverted calls.
–Leave a Message: Lights the lamp of the extension called. It also
stores 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 extension's lamp to warn them you are
waiting. It also stops other calls interrupting you.
–Intrude: Forces the other extension's call into a conference with you
(not available to all phones).
Arrange a Callback
Callback - Alias:
- Ringback.
- Callback when free.
- Callback when next used.
If the extension you call is busy or just rings, 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 any time.
The Ringer Timeout sets how long a callback rings your extension
before it cancels (see page 22). The system also cancels any callbacks
that have not taken place after a set period (default 2 hours).
To arrange a Callback:
1. Dial FEATURE 2.
2. The system ends your call (unless you already had a callback set).
3. You can make and receive other calls while waiting.
To clear the Callback:
1. Dial FEATURE 2again
Leaving a Message
If the extension you call has a message lamp, you can leave a message
(see page 16). This lights that phone's lamp and stores your number for
a return call (supported on INDeX DT and TT phones). If your call is
diverted, the message goes to the extension you first called.
To leave a message:
1. Dial FEATURE 1.
2. Your call ends unless the phone called has already reached its limit
of 5 stored messages.

Switching a Divert On
External Diverts:
Selecting a system speed
dial for Divert All allows you
to divert your calls to an
external number. When you
do this, internal callers hear
a triple tone to warn them of
the external divert.
A divert is switched on by setting a divert number. It is switched off by
cancelling that number.
When divert all is on, you hear broken dial tone if you lift the handset or
press Answer Release but you can still make calls. Switching divert all
on takes the DT1 out of group or no calls.
To set a divert number:
1. Without lifting the handset, dial FEATURE .
2. Short-chirp: Dial 10 (divert all), 11 (divert on busy) or 12 (divert on
no answer).

mistake, dial to restart entry.
4. Deep double-ring: Passcode not accepted. Dial the passcode again
or press FEATURE to stop.
5. Double-ring: The phone already has a divert number set. To stop
press FEATURE. To clear the stored divert number press .
6. Single-ring: The phone has no divert number set. Either press
FEATURE to stop or dial a new divert number followed by #.

speed dial number followed by #for an external divert.

to stop or repeat the step above.
