OPERATION MODES
M2M
M2M stands for "machine-to-machine, man-to-machine or machine-to-man" communication.
M2M is a simple way to use wireless data transmission as a link between sys tems, remote devices
or locations and individuals.
2002 Nokia Corporation. All rights reserved.6
The Nokia 31 terminal can be combined with the Nokia M2M Gateway to provide wireless
connections (Text Messaging, USSD, GPRS, CSD) for machine-to-machine communications. This
combination forms part of an application solution which can remotely monitor or control a pool
of devices or to connect them with existing systems.
With the Nokia 31 terminal connected to a machine through a control application, you can
remotely control a pool of devices and receive status information. The Nokia 31 terminal can be
easily integrated into various applications such as vending, security and meter control.
As an M2M communications device, the Nokia 31 terminal can be used in three operation modes:
AT command mode
M2M system mode
User control mode
AT command mode
In the AT command mode, the Nokia 31 terminal operates as a wireless modem. The wireless
connection is established and data is sent using AT commands. The AT commands which are used
to control the Nokia 31 terminal can be found in the AT Command Guide found on the Nokia 31
CD-ROM or www. americas.forum.nokia.com.
By physically connecting the Nokia 31 terminal to the RS-232 data adapter, the terminal can be
connected to a compatible PC and used as a stand-alone GSM wireless modem. The modem uses
normal communication applications such as e-mail, fax and Internet browsers.

M2M system mode
In the M2M system mode, the Nokia 31 terminal is combined with the Nokia M2M Gateway to
form a complete, wireless end-to-end solution for machine communication.
Some of the enhanced M2M features incorporated into the Nokia 31 terminal include:
enhanced reliability and security
automatic reset if the connection between the Nokia 31 terminal and the application module
is found to be broken
mutual authentication between the Nokia 31 terminal and the Nokia M2M Gateway
data can be exchanged using CORBA method calls integrated in the application module
User control mode
User control mode enables simple applications to be controlled by mobile handsets with text
messages (Short Message Service). The control or monitoring is through general-purpose inputs
and outputs of the M2M System connector of the Nokia 31 terminal. T ext message templates that
are sent from the mobile to the Nokia 31 terminal instruct the terminal, which in turn controls a
device or system, attached to it through the M2M System connector.
DATA CONNECTIONS AND MESSAGING
The Nokia 31 terminal supports four GSM wireless network data protocols.
2002 Nokia Corporation. All rights reserved.8
GPRS
With General Packet Radio Service (GPRS), data is transferred over the network in small, efficient,
standardized packets. The Nokia 31 terminal supports GPRS multi-slot class 6 protocol which
provides multiple timeslots for data transfer. Th e use of G PRS s ervices requires that y our netw ork
service provider supports GPRS (General Packet Radio Service) technology and you must have
subscribed to this service. The pricing of GPRS services may differ from that of normal GSM data
services. Please contact your network service provider for more information.
CSD
Circuit Switched Data (CSD) offers wireless data transfer at rates of up to 14.4 kilobits/sec.
Text Messaging
Text messaging (also called "Short Message Service") is used to send and receive messages
containing a maximum of 160 characters. Text messaging is a convenient way to pass data quickly
and easily among Nokia 31 terminals.
USSD
Unstructured Supplementary Services Data (USSD) offers reliable , interactive messa ging service s.
USSD can be used to send and receive messages containing a maximum of 182 characters. With
USSD, the session is established for the duration of the connection. This increases data transfer
reliability and shortens response times.The use of USSD services requires that your network service
provider supports USSD technology and you must have subscribed to this service.

Note: USSD messages can only be sent to the network, not directly to another mobile
terminal.
SUPPLEME NTARY SERVICES
The Nokia 31 terminal also supports additional network dependent services such as:
Call forwarding – forwards your calls to another number which you specify.
Call restriction – restricts outgoing and incoming calls.
Call transfer – connects two different callers with each other then disconnects one’s own call
without disturbing the other two callers.
Call waiting – alerts you to an incoming call during a phone call.
In-call handling – switches between incoming and active calls.
Multiparty call – connects several callers in a single conversation.
Security option – allows restrictions such as call barring.
SECURITY
By default, the Nokia 31 terminal uses a stand ard PIN reques t. For ad ditional s ecurity, there is an
"AutoPIN" feature which can be configured to relay the PIN code to the terminal’s memory and
make the SIM card useless to any unauthorized user. The AutoPIN feature is activated by
connecting the Nokia 31 terminal to a PC and running the Nokia 31 Configurator software located
on the Nokia 31 CD-ROM or downloadable from www.americas.forum.nokia.com
terminal also includes security-related features such as GSM security codes and GSM encryption.

To find the best installation location, you can use the Intensity of Field strength (IoF) function
through the terminal’s light indicators (LEDs) to find the strongest signal (see “Signal Strength”
on page 17). For more detailed information on placing the terminal, refer to the information at
www.americas.forum.nokia.com
Note: All radio transmitting devices send signals which may cause interference in
different electronic devices ( PC, television etc.). To avoid interference, place the
terminal as far as possible from other electronic devices.
.
ANTENNA S
The Nokia 31 terminal is equipped with an
efficient internal dual-band antenna;
however, depending on the installation
location and surrounding materials, the
signal strength reaching the Nokia 31
terminal may not be sufficient.
The Nokia 31 terminal has an external
antenna connector which allows you to
connect an external antenna adapter (XRM-
1). The adapter allows you to connect an external GSM antenna (with standard FME connector)
and improve signal reception. Once the external antenna is connected, the internal antenna of the
Nokia 31 terminal is not in use.
In order to properly fit the antenna cable adapter to the Nokia 31 terminal , yo u nee d to cut out a
small piece of the terminal cover which normally covers the external antenna connector.
