1. DOCUMENT OVERVIEW

This document is a Technical Specification for Nokia 30 GSM Connectivity Terminal and Nokia 31 GSM Connectivity Terminal (in the document referred to as the “Nokia GSM Connectivity Terminal” or simply as the “terminal”). In this document product hardware specifications, interfaces and other technical specifications are depicted in some detail.

2. NOKIA GSM CONNECTIVITY TERMINALS

The Nokia GSM Connectivity Terminal is a machine-to-machine (M2M) communications device that provides wireless connectivity and remote management possibilities for different applications. The Nokia 30 terminal offers General Packet Radio Service (GPRS), Unstructured Supplementary Services Data (USSD), high-speed data, voice and other advanced services to be used in EGSM900/GSM1800 networks. The Nokia 31 terminal offers the same advanced services for use in GSM850/1900 networks.

Note: Nokia 31 terminal supports data call bit rates from 2400 to 14400 bps.

The Nokia GSM Connectivity Terminal is a GSM transceiver with built-in data capabilities, a SIM card reader, an internal antenna, an external antenna connector and an integrated M2M System Connector. A programmable application module Nokia Smart Adapter, a serial port (RS-232) adapter, an external antenna adapter (an adapter for standard external antennas), power supply and Configurator software (tool for setting terminal parameters) are available as accessories.

The terminal can be used in three different logical operation modes. In the M2M System mode it functions as part of Nokia M2M Platform with Nokia M2M Gateway. In the AT Command mode it functions as a wireless GSM modem and in the User control mode it’s inputs and outputs can be controlled with specific text messages.

For more information about Nokia GSM Connectivity Terminal, Nokia M2M Platform or application development, please visit our website at http://www.forum.nokia.com/m2m or http://www.americas.forum.nokia.com and M2M links.


5/36



3. OPERATION MODES

A Nokia GSM Connectivity Terminal can be used in three different logical operation modes: User Control Mode, AT Command Mode and M2M System Mode.

3.1 USER CONTROL MODE User control mode enables simple applications to be controlled by mobile handsets with specific text messages (SMS). The control or monitoring is through general-purpose inputs and outputs of the terminal.

There are three general-purpose inputs and five general-purpose outputs on the M2M system connector. The inputs can be used in either digital (on/off) or analog (continuous signal) mode. The outputs can be used in digital mode only (set something on/off).

There are different levels of access control for User control mode. User defined message identifier and commands (aliases) add security. Access can be secured by specifying from which phone numbers the requests for control are allowed and by defining a password.

A detailed description of User control mode functionality is given in reference 3.

3.2 AT COMMAND MODE In AT command mode, the terminal acts as a normal cellular modem using AT commands. It can be connected to a PC or a compatible device. Normal communication applications (e.g. e-mail, fax, WWW) can be used.

All the mandatory and optional ITU-T V.25ter /1/, ETS GSM 07.07 /2/, and ETS GSM 07.05 /3/ commands that are applicable to the Nokia GSM Connectivity Terminal are included in the Nokia 30 terminal and Nokia 31 terminal command set. The 'de facto' commands that are widely used with modems are also supported. Note that the ITU-T V.25ter is a combination of three TIA standards (TIA-602, TIA-615, IS-131). Supported AT commands are described in detail in reference 4.

3.3 M2M SYSTEM MODE The M2M System Mode offers an effective application programming interface (API) for building an M2M communications solution. The objective is to provide network-transparent programming through vendor, operating system and language-independent CORBA architecture.


6/36

The M2M System mode is available via the M2M System Connector or DB9 connector of the RS-232 data adapter accessory.

Note: M2M System interface availability with the RS-232 data adapter accessory depends on the software version of the Nokia 30 terminal and Nokia 31 terminal. Please see Reference 2 for details.

For more information about the services offered by the M2M System mode, see chapter 5.2. For a brief description of CORBA middleware see Appendix 1.

4.1 DATA CONNECTIONS The Nokia 30 terminal supports High Speed Circuit Switched Data (HSCSD), GPRS and Circuit Switched Data (CSD) for wireless data connections. The Nokia 31 terminal in turn supports GPRS and CSD. Both terminals also support


8/36

SMS (Short Message Service) and USSD (Unstructured Supplementary Data) messaging services that can also be used as wireless data bearers (see chapter 4.2).

In M2M System mode the terminals support wireless bearer selection that enables changing between bearers (GPRS, CSD, HSCSD, SMS and USSD) dynamically.

Note: Nokia 31 terminal supports data call bit rates from 2400 to 14400 bps.

When using HSCSD, the Nokia 30 terminal can send and receive data with several time slots at the same time. This makes the data transfer rate higher. The time slot usage is presented as the number of downlink and uplink slots used. The maximum data transfer speed of 43.2 kbps downlink can be achieved with 3+1 time slot configuration.

In GPRS data is transferred over the network in small, standardized packets, whereas in the circuit switched data transfer uplink and downlink slots are reserved for the whole duration of the transfer. Transferring data as packets makes the transfer more efficient. In GPRS a mobile can send and receive data packets using several time slots at the same time, and time slot usage is presented as the number of downlink and uplink slots used. The maximum data transfer speed of GPRS is comparable to that of the HSCSD. It can be achieved downlink with 3 + 1 time slot configuration.

4.2 MESSAGING SERVICES The Nokia GSM Connectivity Terminal support SMS and USSD messaging.

The Short Message Service allows the user to send and receive messages with the terminal. The service can deliver messages to the terminal whenever it is connected to the network, even when the terminal is engaged on an active call. SMS is a convenient way to pass data quickly and easily to and from the terminals.

The Nokia GSM Connectivity Terminal supports SMS in ASCII and PDU formats. In the case of ASCII format the 7-bit coding and encoding is supported, which allows message lengths of up to 160 characters.

In User Control mode the message format is 7-bit coded ASCII.

In AT command mode when the PDU format is used the message coding and encoding is provided by the application module, and can for this reason chosen freely. For information about how to set the PDU format in a terminal in AT command mode, please see reference 4. More information about the PDU format coding and encoding can be found in references 13 and 14.


9/36

In AT command mode, while the PDU-mode is selected, the coding and encoding provided by the application module could be that of a Unicode message for graphical character sending. More information about the Unicode message format and graphical character coding and encoding can be found in references 13 and 14.

When SMS is used as a wireless data bearer in M2M System mode, the message format is PDU. The terminal provides the coding and encoding of the messages and the SMS is accessible for data transmission through the terminal API.

USSD offers reliable interactive messaging services. It allows the user to send and receive messages of up to 182 characters with the terminals. When USSD is used, a session is established for the duration of the connection. This increases data transfer reliability, as the delay is known. In addition, it shortens response times.

4.3 VOICE SERVICES The Nokia GSM Connectivity Terminal supports voice services on M2M System Connector. There are interfaces for digital or analog audio. Please see chapter 5.5.

4.4 APPLICATION HOSTING ON-BOARD A Nokia Smart Adapter is a programmable application module with standard RS-232 serial interface that enhances the functionality of the Nokia GSM Connectivity Terminal.

For more information about the Nokia Smart Adapter, see reference 11. For information about application software development for Nokia Smart adapter, see reference 12.

5.2 M2M SYSTEM INTERFACE The M2M System interface offers all the functionality and intelligence of a Nokia GSM Connectivity Terminal for the application through an API. The API offers functionality such as terminal light indicator handling, event observation, call control, GPRS connection setup, IO control and monitoring, cell ID location


14/36

information and parameters access. In addition to be accessed locally, the API can also be accessed remotely.

Between the terminal and the external device the M2M system interface offers an effective and reliable protocol, namely the M2M system protocol (based on MAP27 data link layer protocol), for controlling the terminal. M2M system protocol is a data link layer protocol and it is described in reference 7.

The connection between the Nokia GSM Connectivity Terminal and the application module is checked periodically when using the M2M System protocol.

On M2M System Connector, the M2M System interface is available via both of the two serial ports supported. The M2M System port is permanently reserved for M2M System interface and the RS-232 port can be configured for the M2M System interface connection type (See chapter 5.3.3).

The same connection type configuration also sets the M2M System interface to the DB 9 connector of the RS-232 data adapter.

Note: M2M System interface availability on RS-232 port depends on the software version of the Nokia 30 terminal and Nokia 31 terminal. Please see reference 2 for details.

5.2.1 The Nokia GSM Connectivity Terminal Interfaces The services offered by the Nokia GSM Connectivity Terminal are defined in the following three interface definitions:

• Wireless Device Interface Definition

• Embedded Terminal Interface Definition

• IO Interface Definition The Wireless Device Interface Definition is common for all kinds of devices. The Nokia terminal -specific services are described in the Embedded Terminal Interface Definition and services related to remote input/output control in the IO Interface Definition.

The services defined in the Wireless Device Interface Definition are divided in three interfaces: Device, ParamObserver, and EventObserver. The Device interface has functions to handle dynamic parameters and counters. The EventObserver interface’s services are used for providing information regarding events like incoming calls or network connection loss. ParamObserver interface’s functions are used in the same way, but in their case, to receive notification of changes in dynamic parameters.


15/36

The Embedded Terminal Interface Definition describes GSM related operations, such as call control, Short Message Service (SMS), supplementary services and light indicator control functions. They provide easy access to basically all mobile network services.

The IO Interface Definition has functions for the remote control of the M2M System Connector’s input/output pins. The IOControlObserver interface is used for indicating changes in those pins.

Events are available for devices connected physically to the terminal as well as for some of the method calls. Data structures and exceptions are not restricted and can be utilized by all devices connected to the terminal (irrespective of whether the connections is physical and wireless).

All dynamic parameters and events of the Nokia GSM Connectivity Terminal are described in Properties Interface Definition. Configurations such as connection settings for GPRS or SMS and led state can be set as parameter values. Parameters, counters and events can be handled through the functions of the Wireless Device Interface Definition.

For method descriptions of Wireless Device, Embedded Terminal and IO Interface Definitions, please see IDL reference guide for Nokia GSM Connectivity Terminals. For parameter, event and counter descriptions of Properties Interface Definition, please see Properties Reference Guide for Nokia GSM Connectivity Terminals. For the actual Interface Definitions, please see wirelessDevice.idl, egsmt.idl, io.idl and properties.idl of Nokia GSM Connectivity Terminals.

For more information about Nokia GSM Connectivity Terminal interface descriptions and properties, please see references 5 and 6.

5.3 RS-232 INTERFACE In the AT Command Mode, the terminal is controlled by AT commands and RS-232 handshake signals. RS-232 signals are available at both the M2M System Connector and 9-pin DB connector with RS232 data adapter or Nokia Smart Adapter.

The terminal supports autobauding (9600-115200) for RS-232.

5.3.1 RS-232 Hardware Specifications - M2M System Connector The RS-232 handshake signals are optionally available at 3V level using the M2M System Connector. The signals are described in Table 2.


16/36

5.3.2 RS-232 Hardware Specifications - Data adapter RS-232 RS-232 handshake signals are available at standard level using an RS-232 data adapter or Nokia Smart Adapter (available as accessories) 9-pin DB connector (female). Signal levels are:

Minimum: +/- 3 V

Maximum: +/- 15 V

The terminal sets the flow control signal (CTS) when it is ready to receive AT commands.

The terminal functions as DCE (Data Communication Equipment / Modem) in a PC-environment.

The signals are described in Table 2. The signals' electrical performances are compatible with the RS-232 standard with a maximum data rate of 115,200 bps.

5.3.3 RS-232 Connection type On RS-232 port of M2M System Connector, also other connection types besides the RS-232 link can be used. Four different connection types can be selected for the terminal (for RS-232 port):

• HW selection (Default)

• M2M system protocol

• AT commands

• General-purpose I/O

The selection can be made with the Configurator software or through the API of the M2M System mode. In the following paragraphs the configuration instructions apply for the Configurator software.

Note: The availability of Connection type selection functionality depends on the software version of the Nokia 30 terminal and Nokia 31 terminal. Please see Reference 2 for details.


18/36

HW selection (Default)

When “HW selection (Default)” connection type is selected the Nokia GSM Connectivity Terminal is able to communicate with AT commands or the general-purpose inputs and outputs of the terminal, using the RS-232 port of the M2M System Connector. The connection type is automatically selected according to the connected ID resistor.

If the terminal is mounted e.g. into DAU-12 data adapter, the terminal uses AT commands for communication. If the terminal is mounted into application module, the ID resistor has to be selected according to the desired connection type. See reference 9 for details of the electrical connection.

If no ID resistor is connected, the general-purpose inputs and outputs are available on the RS-232 port of the M2M System Connector of the terminal.

When the “HW selection (Default)” is selected and the terminal is used in the M2M system mode, the communication between the terminal and an application is provided via M2M system port.

M2M system protocol

When “M2M system protocol” connection type is selected the terminal always communicates via RS-232 port using CORBA method calls (on top of M2M system protocol).

Note: When the “M2M system protocol” alternative is selected, the M2M system port is disabled.

Note: This type may be useful e.g. during the application development when debugging the application with a PC and Data adapter RS-232 (DAU-12).

AT commands

When “AT commands” connection type is selected the terminal always communicates via RS-232 port using AT commands and can be used for example as a modem. This connection type is the same as when using HW selection (default) connection type with DAU-12 adapter, except that the general-purpose inputs and outputs cannot be used.

When the “AT commands” is used as a connection type and the terminal is used in the M2M system mode, the communication between the terminal and an application module is provided via M2M system port.


19/36

General-purpose I/O

When “General-purpose I/O” connection type is selected the terminal always communicates via RS-232 port without any data protocol. Thus, all RS-232 handshaking pins are reserved for I/O and no data protocol is available.

When “General-purpose I/O” is set and the terminal is used in the M2M system mode, the communication between the terminal and the application module is provided via M2M system port.

Table 3 illustrates how I/O pins are available in the RS-232 connector of DAU-12 (RS-232 port on M2M System Connector).

Table 3 Connection types an I/O pin availability in the RS-232 connector of DAU-12 (RS-232 port on M2M System Connector).

The general-purpose inputs and outputs can be controlled with either specific text messages in the User control mode (see chapter 3.1) or using the API of the M2M System Mode (see chapter 3.3).

5.5 AUDIO INTERFACE The Nokia GSM Connectivity Terminal supports full rate (FR) and enhanced full rate (EFR) speech codecs for the GSM network. The voice services are available for the application module through the analog or digital audio interfaces on the M2M System Connector.

The selection for the interface being used is configured to the Nokia GSM Connectivity Terminal. This can be done using the Nokia GSM Connectivity Terminal Configurator. In the M2M System mode the audio parameters are also accessible for configuration through the API. In M2M System mode the configuration can be done either locally or remotely.

For more information on using the audio interfaces described briefly below, see reference 8. For information about the electrical connection to the audio interface, see reference 9.


21/36

5.5.1 Digital audio interface The digital audio data interface between the Nokia GSM Connectivity Terminal and application module is a 13-bit PCM consisting of 4 signals: PCM master clock, frame synchronisation clock, digital audio output and digital audio input.

When digital audio interface is used, the two clock signals need to be provided by an external device (application module) containing an audio codec.

5.5.2 Analog audio The analog audio interface consists of differential Mic and Ear signals.

5.6 POWERING The Nokia GSM Connectivity Terminal has a 3.0 mm DC plug for Nokia ACW-5A or LCM-2 power supply (See Figure 1).

• DC input voltage range: 6.2 V – 14.0 V

• Positive is connected to the centre

The M2M system connector provides regulated switchable power output for the application.

• DC output voltage: 3.6 V

Maximum DC output current: 300 mA

Alternatively, the application module can supply the terminal with a wide voltage range.

• DC input voltage range: 4.75 V – 15.0 V

5.7 USER INTERFACE Three light emitting diodes (LEDs) form the user interface of the Nokia GSM Connectivity Terminal. The LED user interface is shown in Figure 4.

APPENDIX 1: CORBA MIDDLEWARE

The CORBA (Common Object Request Broker Architecture) is a widely distributed computing infrastructure, standardised by the Object Management Group (OMG) consortium. In short, CORBA applications are composed of objects which can be located within different machines. Objects have services and they are utilised with request messages. The CORBA hides the underlying transferring network, such as the Internet or GSM network as well as the underlying protocols, so that a user can use functions as local procedure calls.

Object services are described with an abstract language named IDL (Interface Definition Language). The IDL also provides the necessary information required to develop clients that use an object's interface operations. The interface definition specifies which member functions, data types, attributes and exceptions are available to a client, without making any assumptions about an object’s implementation. An IDL compiler is responsible for mapping IDL interfaces onto the particular programming language, such as C, C++ or Java. Thus, the programming language that is used in CORBA implementation does not have to be object-oriented.

Example applications implemented using CORBA IDL can be found at the Forum Nokia web pages; http://www.forum.nokia.com/m2m or www.americas.forum.nokia.com.
