Product overview

System requirements

The Nokia 22 PBX connectivity terminal can be connected to a digital or ana-

logue PBX. The terminal can be connected either to the trunk connector or the

extension connector of the PBX. The application module has two RJ-11 connec-

tors for both type of connections. Only one of the connectors can be used at a

time.

The terminal can be configured using a DTMF telephone or with the Nokia 22

Configurator Software. For further information , see “6. Accessories” on page 34.

The Nokia 22 supports both DTMF (Dual Tone Multi Frequency) and pulse dial-

ling.

Normal telephone sets and answering machines can be connected directly to the

application module’s trunk connector.

Note: Standard land line telefaxes and modems are not compatible with

the terminal. Only a PC fax application can be used with the Nokia 22

Data Packet. For further information, see “6. Accessories” on page 34.

Important! Do not connect the Nokia 22 to a digital (ISDN) interface of

a PBX.

2. Product features

GSM terminal

The GSM terminal features a dual band transceiver with built-in data capabili-

ties, a SIM card reader, an antenna, a RS-232 data connector, a power supply

and an application interface connector. The GSM terminal provides access to the

data functionality of the GSM system including Short Message System (SMS)

and High Speed Circuit Switched Data (HSCSD). The GSM terminal provides the

subscriber data transmission, one connection at a time.

The Nokia 22 supports only small size SIM

cards. The SIM card should have the PIN

code request activated.

GSM terminal basic features:

• Dual Band GSM 900 MHz & GSM 1800 MHz

• Voice codecs EFR, FR, HR

• PC fax support

• HSCSD (High Speed Circuit Switched Data)

• Mobile Originated and Mobile Terminated SMS with the help of AT

commands

• SIM lock support

• ETS GSM 07.07 and 07.05 compatible AT command set

• GSM Phase 2+ supplementary services

Product features

Application module

The application module has two operating modes: extension mode and trunk

mode. In extension mode the application module is connected to the analogue

extension (private) interface of the PBX. In trunk mode the application module

is connected to the analogue trunk (public) interface of the PBX. The application

module complies with the ETS 300-001 standards for PBX trunk and extension

connections.

The application module can also be con-

nected directly to a normal telephone set.

The telephone can be used like a normal

landline telephone , for example to make

and receive calls.

1. Extension connector

2. Trunk connector

Note: Some telephones sets and PBXs are more sensitive to radio inter-

ference than others and there may occur some audible interference. If

this problem occurs, increase the distance between the terminal and the

PBX or the telephone set.

Warning! To avoid damage to the devices, the telephone set must be

connected to the terminal’s trunk connector with a standard 4-pin RJ-

11 cable that has only its two middle pins connected.

Application module basic features:

• ITU-T standard

• Pulse/DTMF dialling

• Calling Line Identification (CLI)

Product features

• Support for analogue extension and trunk interfacing

• Loop reversal and loop interruption (detection and generating)

• Country specific R-key settings

Application module functionality

The application module can function in different modes when the Nokia 22 is

connected to a PBX. For further information, see “ Functionality in trunk mode”

on page 24 and “ Functionality in extension mode” on page 25.

Call creation

When the PBX or the telephone set connected to the Nokia 22 switches over to

the OFF-HOOK state, the terminal generates a local dial tone.

When the user makes a call, dialled digits are first saved in the memory of the

Nokia 22. The dial tone stops after the first digit is dialled. A four seconds wait-

ing time follows after the last dialled digit. After that the terminal assumes the

telephone number is fully dialled, and a call request is sent to the network. The

call is processed.

A local busy tone will be heard after 30 seconds and a howler tone after 60 sec-

onds if digits are not dialled. In such a situation before a number can be dialled,

the PBX or the telephone set must switch over to the ON-HOOK state and after

that again to the OFF-HOOK state.

Note: When making a call, an area code must be dialled for both local

calls and long distance calls if the network system does not support lo-

cal area dialling or the AAC (Automatic Area Code) feature is not in use.

For further information about the AAC feature, see section “ Automatic

Area Code (AAC) and routing” on page 16.

Note: The generating of dial tones does not depend on the service state

of the GSM terminal. Even if the GSM terminal is not connected to the

GSM network (that is light indicator 3 is blinking on the terminal) the

application module tries to connect the call. Thus, emergency calls can

be made using any network service provider available or even without a

SIM card in the terminal. For a description of the terminal light indica-

tors, see “ Light indicators”on page 12.

Product features

Call termination

When the PBX or the telephone set connected to the Nokia 22 terminates the

call by switching over to the ON-HOOK state, the Nokia 22 terminates the GSM

connection immediately.

When the B subscriber terminates the call, the GSM connection of the terminal

is terminated as the PBX or the telephone set connected to the terminal switch-

es over to the ON-HOOK state.

Light indicators

There are five light indicators on the

Nokia 22.

Light indicators 1 and 2 indicate the

state of the application module and light

indicators 3, 4 and 5 indicate the state of

the GSM terminal.

The terminal is ready for use when the

light indicator 3 is lit.

The use of light indicators is described in Table 1: Application module light

indicators and Table 2: GSM terminal light indicators.

Short Message Service (SMS)

The Nokia 22 supports both Mobile Originated (MO) and Mobile Terminated (MT)

short message services with the help of AT commands.

A PC and the Nokia 22 Data Packet are needed when using the SMS feature.

When an SMS message is received the light indicators 3, 4 and 5 light up and a

tone indicator (--- --- ---) is heard through the telephone set’s receiver.

Note: SMS message received signals are reset when the receiver is lifted

off-hook.

Voice mail

The Nokia 22 supports the GSM network voice mail service. If the network sends

an SMS of received voice mail, the terminal will indicate the received SMS by

Product features

means of light indicators and also by means of tone in the telephone set’s re-

ceiver. For further information, see “ Short Message Service (SMS)”on page 15.

High Speed Circuit Switched Data

(HSCSD)

The GSM terminal supports High Speed Circuit Switched Data that enables a

data transmission speed of up to 43.2 kbps. The High Speed Circuit Switched

Data (HSCSD) relies on the simultaneous use of multiple GSM timeslots.

For the terminal data transfer modes, see “7. Technical specifications” on page

36. The Nokia 22 Data Packet is required to use this feature.

The HSCSD is a network service. For details, contact your service provider.

Calling Line Identification (CLI)

The Calling Line Identification (CLI) feature displays the caller’s number with an

external calling line display device.

Two signalling methods are available, ETSI FSK (European Telecommunications

Standards Institute Frequency Shift Keying) and DTMF (Dual Tone Multi Fre-

quency).

The signalling mode varies depending on the operator and the country. The de-

fault mode is ETSI FSK. For information about changing the CLI mode, see “

Changing Calling Line Identification (CLI) mode” on page 32.

Note: The CLI devices are not provided by Nokia. For details and avail-

ability, contact your service provider.

Automatic Area Code (AAC) and routing

The Automatic Area Code (AAC) feature allows the user to dial local numbers

without a local area code in the GSM network. Before the number is sent a pre-

programmed local area code is added automatically by the Nokia 22.

The user can also specify that the terminal changes certain prefixes automati-

cally, for example to provide a cost-effective route. The AAC and routing settings

can be modified using the Nokia 22 Configurator Software.

Product features

Intensity of Field (IOF)

The Intensity of Field (IOF) feature indicates the strength of the received radio

signal. The IOF is indicated by the light indicators. The feature can be activated

with a DTMF telephone connected to the terminal’s trunk connector. To activate

the feature, key in 777**#. The feature is automatically deactivated when the

DTMF telephone’s receiver is replaced on the hook. For further information on

the IOF feature, see “3. Setting up the terminal” on page 18.

Faster call setup

Faster call setup allows a faster call establishment. The last 10 different dialled

numbers are stored in the memory of the Nokia 22. If the dialled number match-

es one of the stored numbers, there is no delay before the terminal sends the

number and the call is established immediately.

Note: Only successful (answered) calls are stored in the terminal’s

memory.

AutoPIN security feature

The Nokia 22 has an AutoPIN security feature. It saves the PIN code in the

terminal’s memory when the code is entered for the first time or when the code

is changed. In addition, the AutoPIN feature enables device recovery after

occasional power cuts without on-site intervention. The terminal enters the PIN

code automatically the next time it switches on and requests the PIN code. For

changing the PIN code, see “ Security options” on page 53.

Use of the SIM card in other GSM terminals or mobile phones can be prevented.

The user does not have to know the PIN code. However, other SIM cards can be

used with the terminal. The AutoPIN feature can be deactivated using the Nokia

22 Configurator Software.

The default value is that the AutoPIN feature is active.

Setting up the terminal

3. Setting up the terminal

work. In 20-30 seconds, light indicator 3 lights up to indicate the network con-

nection and light indicator 1 to indicate the PBX trunk connection.

If the AutoPIN feature is not active, you have to enter your PIN code. For infor-

mation about entering the PIN code, see “ Entering the PIN code” on page 19.

For details, contact your PBX supplier.

PBX installation

Warning! Inappropriate installation of the Nokia 22 to a PBX may

damage the PBX or the Nokia 22. If an extension line of the PBX is

connected to the trunk connector of the Nokia 22, the devices attempt

to feed current to each other and they can be damaged.

To avoid damage to the devices, an analogue trunk line of the PBX must

be connected to the terminal’s trunk connector with a standard 4-pin

RJ-11 cable that has only its two middle pins connected.

Note that the terminal’s trunk and extension connectors cannot be used

at the same time to connect a device.

Important! Do not connect the Nokia 22 to a digital (ISDN) interface of

a PBX.

Making test calls

Incoming call

Make a call to the Nokia 22 GSM number. For details, contact your service pro-

vider. The Nokia 22 redirects the call and sends a ring tone to the PBX trunk line.

The switching centre answers and redirects the call.

Outgoing call

PBX has to be configured to route certain outgoing numbers (for example num-

bers with mobile prefix) to the trunk line the Nokia 22 is connected before an

outgoing call can be made. When a number is sent by the PBX to the terminal,

the terminal connects the call.

For terminal functionality in trunk mode, see section “ Functionality in trunk

mode” on page 24.

PBX installation

Connecting the Nokia 22 to an extension

line of a PBX

1 Disconnect the Nokia 22 PBX connectivity terminal power supply from the AC

wall outlet.

2 Connect the Nokia 22 to a free PBX extension line with an RJ-11 cable.

3 Reconnect the power supply to the terminal.

If the AutoPIN feature is active, the terminal automatically connects the net-

work. In 20-30 seconds, light indicator 3 lights up to indicate the network con-

nection and light indicator 2 to indicate the PBX extension connection.

If the AutoPIN feature is not active, you have to enter your PIN code. For infor-

mation about entering the PIN code, see “ Entering the PIN code” on page 19.

For details, contact your PBX supplier.

Warning! Inappropriate installation of the Nokia 22 to a PBX may

damage the PBX or the Nokia 22. If an extension line of the PBX is

connected to the trunk connector of the Nokia 22, the devices attempt

to feed current to each other and they can be damaged.

To avoid damage to the devices, an analogue extension line of the PBX

must be connected to the terminal’s extension connector with a stand-

ard 4-pin RJ-11 cable that has only its two middle pins connected.

Note that the terminal’s trunk and extension connectors cannot be used

at the same time to connect a device.

PBX installation

Important! Do not connect the Nokia 22 to a digital (ISDN) interface of

a PBX.

Making Test Calls

Incoming call

Make a call to the Nokia 22 GSM number. For details, contact your service pro-

vider. The Nokia 22 answers the call and places the PBX extension line off-hook.

The PBX provides a dial tone and you can dial the desired extension or outgoing

number. The PBX connects the call.

Outgoing call

Make a call to the PBX extension number where the Nokia 22 is connected. The

Nokia 22 answers the call. You hear either a dial tone or silence depending on

the settings of the terminal. Dial the desired number. The terminal connects the

call.

The PBX can also be configured to route certain numbers automatically.

For terminal functionality in the extension connection, see “ Functionality in ex-

tension mode” on page 25.

Note: Some PBXs are more sensitive to radio interference than others

and there may be some audible interference. If this problem occurs, in-

crease the distance between the Nokia 22 PBX connectivity terminal

and the PBX. If there are other problems with the product or with con-

necting the product to the PBX, please consult your local dealer, service

provider or Nokia Mobile Phones for further information.

Note: When the Nokia 22 is connected to an extension line of a PBX,

some precautions must be taken into account. If no calling restrictions

have been set up, any caller calling the Nokia 22 PBX connectivity

terminal’s GSM number gains access to the outgoing PBX trunk line and

can make phone calls that are charged to the PBX owner.

To prevent this situation, the PBX must be configured to deny any out-

going calls coming from the extension line the Nokia 22 is connected to.

If the PBX cannot be configured in such a way, it is possible to configure

the Nokia 22 to automatically call a predefined extension number when

it receives a GSM call. For further information, see “5. Configuration” on

page 30. For more information about PBX configuration, see your PBX

User’s Guide.

Configuration

5. Configuration

Methods

The Nokia 22 PBX connectivity terminal can be configured using a DTMF tele-

phone connected to the application module or using the Nokia 22 Configurator

Software. The Nokia 22 Configurator Software is a tool for the configuration of

the terminal. For further information, see “6. Accessories” on page 34.

The settings can also be modified via a PBX.

Note: When multiple Nokia 22 PBX connectivity terminals are connect-

ed to a single PBX, the PBX may treat them as a pool of devices. As a

result, it is not possible to change the settings of a specific Nokia 22

connectivity terminal via the PBX. For further information, contact your

service provider.

For terminal tone indicators, see “ Terminal tone indicators” on page 20.

Basic settings

Basic settings include PIN and PUK code input, the speaker volume control and

activation of the Intensity of Field (IOF) feature.

Entering PIN and PUK code

To enter the PIN code, key in PINCode#.

To enter the PUK code, key in PUKCode#.

Entering PIN code does not succeed

If entering the PIN code fails three times, the code is blocked. You can unblock

it by entering your PUK (Personal Unblocking Key) code. The PUK code may be

supplied with the SIM card. If not, contact your local service provider for the

code. If you lose the code, contact your service provider. When the PIN code is

blocked, light indicators 3 and 4 blink. To unblock the code, proceed as follows:

1 Lift the receiver of the DTMF telephone connected to the Nokia 22. When the

enter PUK code tone is heard, enter the PUK code followed by #.

2 Enter a new PIN code (4-8 digits) followed by # when light indicator 4 blinks

and the enter PIN code tone is heard.

• If the terminal or any of its accessories are not working properly, take them

to your nearest qualified service facility. The personnel will assist you, and if

Care and maintenance

necessary and make arrangements for service.

10. Troubleshooting

Always check light indicators when problems are encountered. For the use of

light indicators, see “ Light indicators” on page 12.

First things to check

1 Check that all line cables are connected properly.

2 Check that the power supply is firmly connected to the Nokia 22 and the AC

wall outlet.

3 Check that the antenna is firmly connected to the terminal.

Light indicator 3 is blinking

The Nokia 22 is not in service. The terminal is not connected to the network, the

signal is too weak or the antenna is not connected to the terminal.

Replace the receiver and wait for a while, then try again. You can also move the

terminal to another location and then try again. See also “ No tone can be heard

when you lift the receiver” on page 46.

No tone can be heard when you lift the

receiver

Disconnect the power supply from the Nokia 22. Wait for 10 seconds. Reconnect

the power supply to the terminal. Operation succeeds when light indicator 3 is

lit continuously and you hear the dial tone.

Note: If the AutoPIN feature is disabled or the SIM card is installed for

the first time, the enter PIN code tone is heard. Enter the PIN code. After

that you should hear a dial tone within 30 seconds.

Troubleshooting

Call is disconnected immediately after

answering

Check that the antenna is properly connected to the Nokia 22. If the terminal is

still not working, contact the local dealer, service provider or the nearest Nokia

Mobile Phones representative.

Appendix: Supplementary

services

Supplementary services are network services. They are cellular services provided

by network operators and therefore differ from one network to another.

Supplementary services provide the subscriber with an opportunity to control

incoming and outgoing phone calls. The Nokia 22 PBX connectivity terminal

supports the following GSM Phase 2 + supplementary services.

• Number identification

• Call offering

• Call completion

• In-call handling

• Call restriction

• Security options

• Call transfer

Note: The call offering supplementary service and the call restriction

supplementary service cannot be deactivate at the same time.

How the supplementary services work

The activation, deactivation, request and registration of a supplementary service

function in the same way as in a mobile phone. The dialled supplementary serv-

ice sequence will be executed after 4 second’s dial time-out. The Nokia 22 re-

sponds to a supplementary service activation, deactivation, request and

registration by sending OK or error tones from the telephone set’s receiver.

Number identification

Calling Line Identification Presentation (CLIP)

The CLIP (Calling Line Identification Presentation) feature displays the caller’s

number on an external CLI (Calling Line Identity) device. The CLI device must be

connected between the Nokia 22 and the DTMF telephone. In order to connect

the CLI, signalling mode must be activated.

Troubleshooting

Note that the CLIP function usually has to be activated by the network operator.

To request this function, key in *#30#.

Calling Line Identification Restriction (CLIR)

The CLIR (Calling Line Identification Restriction) feature offers the user an op-

portunity to prevent his/her number from being shown to the B subscriber.

The network operator sets the CLIR either to ON or OFF state for the subscriber.

It is also possible to revert to the CLIR status for one call at a time.

If, for example the CLIR is disabled (that is a phone number will be shown to the

called person), invoke the CLIR by keying in #31#PhoneNumber.

The phone makes a normal call to the PhoneNumber but the B subscriber will

not be able to see the Nokia 22 phone number.

If the CLIR has been set permanently to the ON state (that is the phone number

is normally never shown to the B subscriber), key in *#31# to show the number.

Call forwarding (Call offering)

These functions allow the user to forward incoming calls.

• Unconditional call forwarding, also called call offering, allows incoming calls

to be directed to another number (network service).

• Busy call forwarding allows the subscriber to direct incoming calls to another

number when the telephone set is busy. Usually, the CFB service has to be

first activated by calling the operator’s service number (network service).

• No reply call forwarding enables the subscriber to direct incoming calls to

another number when the calls are not answered. Usually the CFNRy service

has to be first activated by calling the operator’s service number (network

service).

• Not reachable call forwarding allows the subscriber to direct incoming calls

to another number when the network is not in service or the terminal is pow-

ered off. Usually the CFNRy service has to be first activated by calling to the

operator service number (network service).

Call waiting (Call completion)

Call waiting, also called call completion, alerts the subscriber of another incom-

ing call during a phone call (network service).

To request call waiting, key in *#43#.

To activate call waiting, key in *43#.

To deactivate call waiting, key in #43#.

In-call handling

These functions allow the user to switch between phone calls. The service is con-

trolled by the R (register recall) button.

Important!

Restricting calls in some networks may restrict the ability to make

emergency calls. If this is the case in your network, ALL USERS OF

THE TERMINAL MUST BE INFORMED by appropriate warning signs

on ALL phones connected to the terminal.

The effect of call restriction varies among networks so each opera-

tor must provide its own warning signs that accurately describe any

emergency restrictions.

Test the effect of call restriction on calls to your local emergency

number(s) and warn as needed.
