Warnings and Cautions
Please refer to the phone's user guide for instructions relating to operation, care and
maintenance including important safety information. Note also the following:
Warnings:
1.CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED WITH ELECTRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI-SKID BRAKING SYSTEMS. UNDER CERTAIN FAULT CONDITIONS, EMITTED RF ENERGY CAN AFFECT THEIR OPERATION. IF NECESSARY, CONSULT THE VEHICLE DEALER/ MANUFACTURER TO DETERMINE THE IMMUNITY OF VEHICLE ELECTRONIC SYSTEMS TO RF ENERGY.
2.THE HANDPORTABLE TELEPHONE MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES EG PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.
3.OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULAR TELEPHONES, MAY INTERFERE WITH THE FUNCTIONALITY OF INADEQUATELY PROTECTED MEDICAL DEVICES. CONSULT A PHYSICIAN OR THE MANUFACTURER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY ALSO BE SUBJECT TO INTERFERENCE.
Cautions:
1.Servicing and alignment must be undertaken by qualified personnel only.
2.Ensure all work is carried out at an anti-static workstation and that an antistatic wrist strap is worn.
3.Ensure solder, wire, or foreign matter does not enter the telephone as damage may result.
4.Use only approved components as specified in the parts list.
5.Ensure all components, modules screws and insulators are correctly re-fit- ted after servicing and alignment. Ensure all cables and wires are repositioned correctly.

Introduction to DTX-3 (Nokia 32)
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 GSM- to-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.
