Introduction to DTX-3 (Nokia 32) ....................................................................................................... 3
Product Concept Generally ................................................................................................................3
Nokia 32 PBX Connectivity Terminal includes two modules:
1. Nokia TME-3 or Nokia TME-4 GSM transceiver
2. Nokia DTX-3 application module.
The Nokia TME-3 is a Class 4/5 (EGSM900) and Class 1/2 (EGSM1800) dual band GSM
terminal. The Nokia TME-4 is a GSM850/1900 dual band terminal.
The DTX-3 provides an analogue two-wire connection for a landline telephone set or PBX
(Private Branch eXchange) trunk or extension connection.
The main purpose of the Nokia 32 is to provide direct GSM connection for companies
using fixed line PBX.
Calls targeted to the GSM network can be diverted via Nokia 32. Thus the company gets
a direct connection to a GSM network from the internal fixed line telephones without
the costly interconnection fee between fixed and GSM networks.
Product Concept Generally
Nokia 32 PBX connectivity terminal is a GSM device for PBX (Private Branch Exchange)
connections. Nokia 32 has interfaces for PBX trunk and extension connections and the
trunk connection can be also used for normal landline telephone connection substituting
fixed telephone line. The terminal also supports data connections with CSD, HSCSD and
GPRS.
The telephone line connections for Nokia 32 are provided with standard two-wire connection through RJ-11 connectors. Each connection method, trunk and extension, have
their own dedicated RJ-11 ports. The data connection is provided via RS-232 connection
over a D9 female connector. In addition, Nokia 32 has interfaces for power supply and
external antenna adapter. Nokia 32 internal antenna is used when there is no need for an
external antenna.
The main purpose of Nokia 32 is to use it as a GSM router beside a company PBX. Company calls to GSM numbers are routed via Nokia 32 in order to gain cost savings in GSMto-GSM calls and the fixed telephone line is bypassed. Nokia 32 also gives the opportunity to use GSM network features in landline environment.
Concept
(For list of abbreviations kindly refer to the manual section Modules.)
1. The Nokia 32 is connected to an analogue trunk interface of a PBX.
2. The Nokia 32 is connected to an analogue extension interface of a PBX.
The Nokia 32 is attached either to an analogue trunk (fig. 1) or an analogue extension

After the Nokia 32 has been connected to a PBX, the PBX may require reconfiguration to
route mobile targeted calls via the Nokia 32. This reconfiguration requires special knowhow about the PBX. In order to perform successful installation, further information must
be asked from the PBX supplier. In no conditions it is recommended to do the installation
without adequate know-how and tools.
When Nokia 32 is connected to the extension side of the PBX, the originator of call
affects to the routing by calling to the extension where Nokia 32 is connected and then
keys in the targeted mobile number.

Functional Description of DTX-3
Circuit Description
The DTX-3 application module connects the TME-3/TME-4 with the fixed telephone network and/or with any unmanned connection, e.g. telemetry, remote control, security systems, remote data retrieval.
The Data module baseband blocks provide the MCU, DSP, external memory interface and
digital control functions in the UPP ASIC . Power supply circuitry, charging, audio processing and RF control hardware are in the UEM ASIC.
The purpose of the RF block is to receive and demodulate the radio frequency signal from
the base station and to transmit a modulated RF signal to the base station.

General ........................................................................................................................... 3
Hardware requirements for Windows 98/NT ..............................................................3
Software Environment of the Support Modules ............................................................ 3
To run the Service Software, a software protection device (PKD–1) has to be connected
to the parallel port. TDF–4 box must connected to PC for flashing purposes.
Note: if this software is to be run on laptops, the power saving feature MUST be
switched off.
Hardware requirements for Windows 98/NT
The recommended minimum hardware standard to run Service Software is any computer
which has a Pentium processor, memory 8 MB and meets HW requirements recommended by Microsoft.
Software Environment of the Support Modules
The Service Software user interface is intended for the following environments:
Microsoft Windows 3.11 (enhanced mode), Windows 95/98 and Windows NT. For those
who are familiar with Windows environment this application will be easy to use. Detailed
information about Windows and application usage can be found from the Microsoft
Windows Users Guide.
As an ordinary Windows application, the main idea in the user interface is that selections
are made with menus, push buttons and shortcut keys.
Selections can be done by using keyboard and/or mouse. There is always a status bar displayed at the bottom of the main window which contains information about current
actions.
Installation
Mechanical Connections
Caution: Make sure that you have switched off the PC and the printer before
making connections.
Caution: Do not connect the PKD–1 key to the serial port. You may damage
your PKD–1 !
Please refer to service setup in this chapter for information regarding different flash set-
ups.
Attach the dongle PKD–1 to the parallel port 1 (25–pin female D–connector) of the PC.
Draft 2 3/03Nokia Corporation.Page 3
Page 31
DTX-3
Service SoftwareCCS Technical Documentation
When connecting PKD–1 to the parallel port, be sure that you insert the computer side of
the PKD–1 to the PC (male side). If you use a printer on parallel port 1, install the PKD–1
between the PC and your printer cable.
The PKD–1 should not affect devices working with it. If some errors occur (errors in
printing are possible) please try printing without the PKD–1. If printing is OK without the
PKD–1 please contact your dealer. We will offer you a new PKD–1 in exchange for your
old one.
Installing the Service Software on PC Hard Disk
The program is delivered on a diskette and is copy protected with a PKD–1 dongle. It
must be present in parallel port when using Service Software.
The program must be installed on the hard disk before use.
Keep the original diskette safe to enable upgrading of the program !

Installation instructions can be found at the following intranet address:-
The label printing function is like N22 label printing function, but it contains only the
application module label. GSM terminal labels are removed. With N32 it is possible to
read the product codes directly from the application module. With N22 the product code
is entered manually.

Visual overlook
The LED indicators are split into two parts:
Figure 2: LED indicators
LED indicators 2&3 are used to tell in which mode the line adapter is at the moment. LED
indicator 1 is used to tell the state of the embedded GSM terminal. At least one LED indicator from both parts should be on or blinking. If e.g. both LED indicator 2 and LED indicator 3 are off, the fault most probably is in the application module.
Initial connections:
1. Insert SIM card to TME-3/TME-4.
2. Attach DTX-3 to TME-3/TME-4.

Ring indicator state
Check that also the state of the Ring indicator changes (it might take few seconds). If
the indicator will not change it's position, change the 'Trunk line state' choice to it's
original setting, and try again couple of times. If the indicator will not change it's position, the DTX-3 is probably broken.
Activate the HF-state from the land-line telephone, or take the earpiece to listen the signal tones. From the Tone generator field you can select different tones to be listened.

Self tests
The following build in selftests will be supported by Nokia 32 in addition to Nokia 22
selftests:
•Line voltage
•Ringing generation/detection
•DTMF generation/detection
•GSM link test
For more detailed information see Ratti SW Selftest Functional Specification .
A dialog box should be developed to start selftests.
The result of individual selftest should be stated clearly with passed/failed/not executed
and the overall result as well.
