7 GSM/GPRS Modes of Operation
GSM/GPRS supports many optional services and modes. The Enfora Enabler III
LPP module supports the following GSM/GPRS services:
• 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 III LPP module has voice capabilities, provided the necessary
connections have been made for the speaker and microphone pins. The Enfora
Enabler-LPP G AT Command Set Reference – LPP0208AT001 has the entire list of
commands that can be used to control the voice functionality.
The Enfora Enabler III LPP module supports four vocoder compression algorithms
for voice communication: Full-Rate (FR), Enhanced Full-Rate (EFR), Half-rate (HR)
and Adaptive Multi-rate (AMR).
