This information consists of a microprocessor and memoryinstalled on a plastic card.Note: The SIM is not provided with the Eagle II module. The SIM must be obtainedfrom the GSM service provider and must be provisioned by the operator for dataand/or voice. Always take care to protect the SIM: the GSM terminal will not operatewithout the SIM installed.The SIM provides the IMSI for authentication. To gain access to the GSM network, thenetwork must recognize the IMSI number, and the terminal must be able to properlydecrypt the data sent by the network. The SIM also serves as a buffer for SMSmessages, storing the message for transmission until a radio link is available andbuffering received messages until retrieved.Using a Remote SIM with the Eagle II ModuleThe Eagle II module also allows the use of a remote SIM—one not installed in theEagle II module.! To utilize a remote SIM, the integrator must provide a suitable SIM connector on theapplication

The Eagle II module supports thefollowing GSM services:! Voice communication! Circuit-switched data! Short-Message Services (SMS)! Group 3 Fax! General Packet Radio Service (GPRS)Enabling the Transmission Modes for the GSM ServicesEach of the GSM services has two modes that can be enabled separately:! Mobile-originated (MO): allows the making of a service request (such as, making atelephone call or sending an SMS)! Mobile-terminated (MT): allows receiving a service request (such as receiving atelephone call or an SMS)Note: Contact your local GSM operator to ensure that the services and modes havebeen provisioned for the SIM.Voice CommunicationThe Eagle II module has full voice capabilities, provided the necessary connections havebeen made for the speaker and microphone pins on the 60-pin I/O connector. The ATcommands and their responses to enter and receive information from the Eagle IImodule. These functions include the ability for dialing, for providing on-hook or off-hook,and for controlling other aspects of the voice call interface.The Eagle II module supports three vocoder compression algorithms for voicecommunication: half-rate, full-rate, and enhanced full-rate (EFR)Circuit-Switched DataIn this mode, the Eagle II module supports both of the connection modes of transmissionthat are provided by GSM:! Transparent data mode delivers a service with a variable error rate, with aguaranteed throughput and delay.! Non-Transparent mode delivers a constantly low error rate but with a non-guaranteedthroughput or delay. The Non-Transparent service provides a performance that isclosest to using a modem over a fixed Public Switched Telephone Network (PSTN)line.Note: All GSM service providers may not support Transparent mode. In thosecases, the Eagle II module switches automatically to Non-Transparent mode.

All rights reserved.All trademarks and copyrights are the property of Xircom, Inc.PROVISIONING THE SIMThe GSM SIM can support optional features or services. Most GSM operators typicallyconfigure the SIM to send/receive voice calls and to receive SMS; however, some mayrequire an additional tariff to enable the SIM to send SMS. The transmission of data andfax are also additional services that may require tariffs and additional provisioning. Eachof these services has two separate modes that must be enabled to allow the service:! Mobile-originated (MO): allows making a service request (such as, making a call orsending an SMS)! Mobile-terminated (MT). allows receiving a service request (such as, receiving aphone call or an SMS)It is imperative for the Eagle II module that the SIM be configured for the optionalservices that are required for the application.GSM Services Supported by the Eagle II ModuleThe Eagle II module supports four GSM services (modes of operation) that must beenabled by the operator:! Voice calls (MO and MT): requires a telephone number! SMS (MO and MT): uses the telephone number for Voice! Fax calls (MO and MT): requires a telephone number! Circuit-switched data calls (MO and MT): requires a telephone numberThe GSM SIM can have as many as three telephone numbers: one number for voicecalls and SMS, one number for fax calls, and one number for data calls.Selecting the Modes of OperationWhen provisioning the SIM for the Eagle II module, enable the following modes ofoperation:! Voice calls: configure the SIM for both MO and MT service (to send and receive)! SMS: configure the SIM either for MT alone (to receive) or for both MO and MT (tosend and receive)! Data: configure the SIM either for MO alone (to send) or for both MO and MT (tosend and receive)Voice SMS Data Fax FunctionMO/MT MT MO XVoice calls, receive SMS, make data callsMO/MT MT/MO MO XVoice calls, receive/send SMS, make data callsMO/MT MT/MO MO/MT XVoice calls, receive/send SMS, make/receive data calls(requires an additional data telephone number)

All rights reserved.All trademarks and copyrights are the property of Xircom, Inc.SOFTWARE INTERFACE OF THE EAGLE IIMODULEThe application sends commands to the Eagle II module via the 60-pin I/O signalconnector. These commands use the AT (from "AT-tention") command set.The Eagle II module operates in one of the following modes:! Command mode: Used for configuring the Eagle II module, for interrogating the GSMnetwork, and for placing and receiving calls. It uses the AT command set via theserial port for communication.! On-line mode: Used after a circuit-switched data call has been established. Data ispassed between the Eagle II module and the controlling application withoutcommand interpretation. The only AT command that is interpreted in On-line mode isthe +++ command. (This command places the Eagle II module in Command modebut does not terminate the circuit-switched data call.)The AT command driver of the Eagle II module never exits the Command state, that is, itnever enters the On-line mode.! In the Command state, characters that are received from the Customer PremiseEquipment (CPE) are treated as AT commands by the Eagle II module.! In response to the commands received from the CPE, the Eagle II module sendscharacters (AT commands) to the CPE.! Various events can also trigger the Eagle II module to sends characters (ATcommands) to the CPE.Format for the AT CommandsThe general format of the command line is: <prefix> <command> <CR>The prefix AT obtains synchronization, identifies the character parameters, and indicatesthat a command may be in the following characters.AT commands are not case sensitive: use either capital letters or lower-case letters forthe AT command.AT Command SetThe following tables summarize the functional categories of AT commands that aresupported by the Eagle II module. For a full description of the AT commands, refer to theEagle II Programmer's Manual.Note: A command description that includes an *asterisk denotes that the GSMservice provider must enable supplementary services functionality before thecommand is available.

By being fully GSM Type Approved, the Eagle IImodule provides seamless integration into the GSM network.The integration issues for the application can be narrowed to the utilization of the ATcommands and the use of the GSM functionality. Coverage and signal quality may beevaluated by using the LED of the on-board status indicator. Additional networkinformation can be determined by using AT commands.Using the Eagle II Developer's Kit to Reduce Development Time and EffortThe Eagle II Developer’s Kit can also speed the development and implementation of anapplication. This kit provides a platform for the development of an embedded applicationand can easily be tailored for custom applications. The kit also provides a significantamount of pre-developed software intended to speed the development of the applicationand to reduce the time required for bringing a new device to market.For more information on the Eagle II Developer's Kit, refer to the Xircom, Inc. web site onthe Internet: www.omnipoint-tech.comIntegrating the Eagle II ModuleNote: Generally, all interfaces that are externally available to the end user need tobe ESD-conditioned and terminated in some way. Many of these interfaces shouldnot be connected with power applied.At the highest level, this is done using some type of GSM test equipment (such as, Racal6103E), a computer, and a serial interface tester. The GSM test equipment must be ableto simulate a GSM call and measure the key parameters related to the module.Additionally, the serial interfaces and some minimal SIM functionality can be verified bysending AT commands to the Eagle II module.All of this needs to be verified at ambient as well as extreme conditions.
