7.0 Modes of Operation
GSM/GPRS supports many optional services and modes. The Enfora Enabler II-G module supports the
following GSM/GPRS services:
• Circuit-switched data
• Short-Message Services (SMS)
• Class B GPRS Functionality
• Voice communication
7.1 Enabling the Transmission Modes for the GSM/GPRS Services
Each of the GSM/GPRS 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.
7.2 Voice Communication
The Enfora Enabler II-G 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 Enfora Enabler-G AT
Command Set Reference - GSM0102PB001MAN has the entire list of commands that can be used to
control the voice functionality. The quick start guide in this manual provides a basic command set that can
be used to initialize and test the voice functionality.
The Enfora Enabler II-G module supports three vocoder compression algorithms for voice communication:
Full-Rate, Enhanced Full-Rate (EFR), and Half-rate (HR).
7.3 Circuit-Switched Data
In this mode, the Enfora Enabler II-G module supports both of the connection modes of transmission that
are provided by GSM:
• 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 Enfora Enabler II-
G module can be configured to switch automatically to Non-Transparent mode. This capability depends on
the settings in the AT+CBST command.
