GSM Indicators
The GSM 1 to GSM 4 indicators signal the status of the respective
GSM module. After connection to the power supply, the VoIP
gateway application starts within two minutes. During that time,
the installed GSM modules and SIM cards are detected. If a GSM
module or SIM card is not detected, the respective indicator
remains off.
If they are detected, the process of module and SIM card
initialisation is commenced. The respective indicator shines red
during the process. If the process is unsuccessful, the LED goes
off. If the indicator turns orange, it means that the module has not
logged-in to any GSM network.
If the LED is green, you can make calls and send SMS via the
respective module.
The respective module LED blinks green quickly during call
establishing. When the connection has been built successfully, the
indicator remains green during the whole call.
