3.4. GSM Board
3.4.1. Board Description
•
In BLUESTAR you can use three types of GSM boards (with various GSM modules):
-
GSM board with two modules Siemens TC35 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 GM47(8)) and 5 board status indicators are located on the front
panel.
Possible statuses of indication LED diodes (units with firmware 02.09.xx and higher):
