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 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.
