3.6.1. Board Description
• In PRIGW you can use seven types of GSM boards (with various GSM modules):
- GSM board with two modules Sony-Ericsson GM22 and two SIM holders.
- GSM board with two modules Sony-Ericsson GM47 and two SIM holders.
- GSM board with two modules Sony-Ericsson GM48 and two SIM holders.
- GSM board with two modules Siemens TC35i and eight SIM holders.
- GSM board with two modules Siemens TC35i and sixteen SIM holders
- GSM board with two modules Siemens MC55i and eight SIM holders.
- GSM board with two modules Siemens MC55i and sixteen SIM holders.
- GSM board with two modules Wavecom Q24CLA and eight SIM holders.
- GSM board with two modules Wavecom Q24CLA and sixteen SIM holders.
- 3G board with two modules SierraWirelless MC8775V and eight SIM holders.
The GSM board contains two GSM modules, circuits for their connection to the PCM bus,
and DTMF receivers. The board is designed on a 4-layer PCB of the size of 160x100mm. Pins 1
and 32 are approximately 1 mm longer in the GSM board system connector and are used for
“hot swap” power feeding, allowing to push the board in and out even during operation. This
feature is handy especially for installation or SIM card replacement. Two FME antenna
connectors (for GSM boards with modules GM22) or two SMA antenna connectors (for GSM
boards with modules TC35 and MC45(6)) and 5 board status indicators are located on the front
panel.
