Subscriber Identification Module (SIM) Carrier
The Eagle II module uses a push/pull SIM carrier (sometimes called SIM reader) and is
installed as a slot on the side of the module. The Eagle II module uses a 3 V removable
“mini-SIM” (or Plug-In) configuration.
The SIM, an integral part of any GSM terminal device, is a “smart card” that is
programmed with subscriber information:
The user information consists of an International Mobile Subscriber Identity (IMSI)
number, which is registered with the GSM provider, and an encryption Ki
(pronounced "key"). This information consists of a microprocessor and memory
installed on a plastic card.
Note: The SIM is not provided with the Eagle II module. The SIM must be obtained
from the GSM service provider and must be provisioned by the operator for data
and/or voice. Always take care to protect the SIM: the GSM terminal will not operate
without the SIM installed.
The SIM provides the IMSI for authentication. To gain access to the GSM network, the
network must recognize the IMSI number, and the terminal must be able to properly
decrypt the data sent by the network. The SIM also serves as a buffer for SMS
messages, storing the message for transmission until a radio link is available and
buffering received messages until retrieved.
Using a Remote SIM with the Eagle II Module
The Eagle II module also allows the use of a remote SIM—one not installed in the
Eagle II module.
To utilize a remote SIM, the integrator must provide a suitable SIM connector on the
application

The maximum distance from the Eagle II to the remote SIM connector must not
exceed TBD cm (TBD inches).

MODES OF OPERATION
GSM supports many optional services and modes. The Eagle II module supports the
following 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 Services
Each 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 a
telephone call or sending an SMS)
Mobile-terminated (MT): allows receiving a service request (such as receiving a
telephone call or an SMS)
Note: Contact your local GSM operator to ensure that the services and modes have
been provisioned for the SIM.
Voice Communication
The Eagle II module has full voice capabilities, provided the necessary connections have
been made for the speaker and microphone pins on the 60-pin I/O connector. The AT
commands and their responses to enter and receive information from the Eagle II
module. 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 voice
communication: half-rate, full-rate, and enhanced full-rate (EFR)
Circuit-Switched Data
In this mode, the Eagle II module supports both of the connection modes of transmission
that are provided by GSM:
Transparent data mode delivers a service with a variable error rate, with a
guaranteed throughput and delay.
Non-Transparent mode delivers a constantly low error rate but with a non-guaranteed
throughput or delay. The Non-Transparent service provides a performance that is
closest to using a modem over a fixed Public Switched Telephone Network (PSTN)
line.
Note: All GSM service providers may not support Transparent mode. In those
cases, the Eagle II module switches automatically to Non-Transparent mode.

SMS: Short Message Services
Short Message Services (SMS) is a feature-rich GSM service. The Eagle II module can
perform the following tasks:
Sending and receiving text messages of up to 160 characters (7-bit characters)
Sending and receiving binary messages of up to 140 bytes (8-bit data)
Submitting a SMS Protocol Data Unit (PDU) to a SMSC (Short Message Service
Center) and storing a copy of the PDU until either a report arrives from the network or
a timer expires
Receiving a SMS PDU from a SMSC
Returning a delivery report to the network for a previously received message
Receiving a report from the network
Notifying the network when the module has sufficient memory capacity available to
receive one or more SMS messages (after the module had previously rejected a
message because its memory capacity was exceeded)
SMS Features Supported by the Eagle II Module
The following list details the key characteristics and assumptions regarding the form of
SMS supported in the Eagle II module.
Supports both mobile-originated (MO) and mobile-terminated (MT) SMS
Delivers the message to a telephone
Supports 8-bit data
Supports Message Class 1
Supports the concatenation of up to 255 messages
Provides a status report indicator
Supports the More Messages to Send (MMS) feature
Allows the definition of a validity period
Provides the Service Center Time Stamp
Alerts the SMSC
Supports Priority
Supports Message Waiting
GPRS (Future/Optional)
General Packet Radio Service (GPRS)
GPRS is the next step in GSM data services: a fully packet-based protocol service with
direct access to the Internet. By bringing the best features of messaging, circuit-switched
services, and packet data into harmony, GPRS promises to make new applications even
more practical and affordable. Future releases of the Eagle II module will support GPRS
mode. Currently, the Eagle II module is hardware-ready for GPRS, if the optional memory
upgrade is installed.

PROVISIONING THE SIM
The GSM SIM can support optional features or services. Most GSM operators typically
configure the SIM to send/receive voice calls and to receive SMS; however, some may
require an additional tariff to enable the SIM to send SMS. The transmission of data and
fax are also additional services that may require tariffs and additional provisioning. Each
of 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 or
sending an SMS)
Mobile-terminated (MT). allows receiving a service request (such as, receiving a
phone call or an SMS)
It is imperative for the Eagle II module that the SIM be configured for the optional
services that are required for the application.
GSM Services Supported by the Eagle II Module
The Eagle II module supports four GSM services (modes of operation) that must be
enabled 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 number
The GSM SIM can have as many as three telephone numbers: one number for voice
calls and SMS, one number for fax calls, and one number for data calls.
Selecting the Modes of Operation
When provisioning the SIM for the Eagle II module, enable the following modes of
operation:
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 (to
send and receive)
Data: configure the SIM either for MO alone (to send) or for both MO and MT (to
send and receive)

SOFTWARE INTERFACE OF THE EAGLE II
MODULE
The application sends commands to the Eagle II module via the 60-pin I/O signal
connector. 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 GSM
network, and for placing and receiving calls. It uses the AT command set via the
serial port for communication.
On-line mode: Used after a circuit-switched data call has been established. Data is
passed between the Eagle II module and the controlling application without
command interpretation. The only AT command that is interpreted in On-line mode is
the +++ command. (This command places the Eagle II module in Command mode
but does not terminate the circuit-switched data call.)
The AT command driver of the Eagle II module never exits the Command state, that is, it
never enters the On-line mode.
In the Command state, characters that are received from the Customer Premise
Equipment (CPE) are treated as AT commands by the Eagle II module.
In response to the commands received from the CPE, the Eagle II module sends
characters (AT commands) to the CPE.
Various events can also trigger the Eagle II module to sends characters (AT
commands) to the CPE.
Format for the AT Commands
The general format of the command line is:   
The prefix AT obtains synchronization, identifies the character parameters, and indicates
that a command may be in the following characters.
AT commands are not case sensitive: use either capital letters or lower-case letters for
the AT command.
AT Command Set
The following tables summarize the functional categories of AT commands that are
supported by the Eagle II module. For a full description of the AT commands, refer to the
Eagle II Programmer's Manual.
Note: A command description that includes an *asterisk denotes that the GSM
service provider must enable supplementary services functionality before the
command is available.

INITIALIZATION AND SETUP EXAMPLES
In the GSM vocabulary, a call from GSM mobile to the PSTN is called a "mobileoriginated call" or "outgoing call." A call from the fixed network to a GSM mobile is called
a "mobile-terminated call" or "incoming call."
In the following examples, “App” refers to the application. The following convention
describes the direction of the data exchange:
The data exchange from the customer application to the Eagle II module is
designated as: App > Eagle
The data exchange from the Eagle II module to the customer application is
designated as: Eagle> App
Note: With the exception of the +++ command (Online Escape Sequence), all
commands must be preceded by the AT attention code (or command prefix) and
terminated by pressing the  character.
In the following examples, the  and  are intentionally omitted for
clarity and space.
Initial Response to the AT Command
After power is applied to the Eagle II module, the module performs a power-up self-test.
The self-test completes within TBD seconds. When queried with the AT command, the
Eagle II module responds with one of the following result codes:
OK signifies that the Eagle II module is ready, that it correctly interprets the AT
command, and that it can execute the command.
ERROR signifies that the Eagle II module does not understand the command or that
the command is invalid.
App > Eagle
AT
Eagle > App
OK
Command valid: module is ready
The Eagle II module must be in Command mode when any command is entered (with the
exception of the online escape sequence +++). Commands entered when the module is
in Online mode are treated as data, and are transmitted as such to the receiving module.

INTEGRATION AND TEST
The Eagle II module has been designed to minimize the amount of time required for
integrating and testing the application. By being fully GSM Type Approved, the Eagle II
module provides seamless integration into the GSM network.
The integration issues for the application can be narrowed to the utilization of the AT
commands and the use of the GSM functionality. Coverage and signal quality may be
evaluated by using the LED of the on-board status indicator. Additional network
information can be determined by using AT commands.
Using the Eagle II Developer's Kit to Reduce Development Time and Effort
The Eagle II Developer’s Kit can also speed the development and implementation of an
application. This kit provides a platform for the development of an embedded application
and can easily be tailored for custom applications. The kit also provides a significant
amount of pre-developed software intended to speed the development of the application
and 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 on
the Internet: www.omnipoint-tech.com
Integrating the Eagle II Module
Note: Generally, all interfaces that are externally available to the end user need to
be ESD-conditioned and terminated in some way. Many of these interfaces should
not be connected with power applied.
At the highest level, this is done using some type of GSM test equipment (such as, Racal
6103E), a computer, and a serial interface tester. The GSM test equipment must be able
to 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 by
sending AT commands to the Eagle II module.
All of this needs to be verified at ambient as well as extreme conditions.
