2N
- ISDN BRI GSM Enterprise Gateway
GSM Indicators
The
GSM 1
and
GSM 2
indicators signal statuses of the respective
GSM modules. Whenever the 2N - ISDN BRI GSM Enterprise
gateway is started, detection of the GSM modules and SIM cards
is carried out. This process is signalled by a red LED, which goes
on a few seconds after voltage is supplied. The GSM module
detection takes a few seconds. In case a GSM module or SIM card
is absent, the red LED keeps shining. If a GSM module is not
supplied, the respective GSM LED is blinking red. After a correct
GSM module initialisation, the SIM card starts logging
into the provider's network, which is indicated by a quickly
blinking green colour. If the log-in has been successful, the LED
goes out. If not, it shines red.
In normal operation, a slowly blinking green LED indicates
establishing of an incoming or outgoing call and a permanently
green LED means a successfully established connection within
the respective GSM module.
A survey of GSM module status signalling is included in Tab. 3
