SIMADO GFX11 System Manual
Emergency Number Dialing
What’s this?
The user should be able to contact service personnel like Fire
Brigade, Ambulance, etc. from GSM network, where he is facing
some adverse situation and needs some help. This is known as
‘Emergency Number Dialing’. SIMADO GFX11 supports this feature.
For GSM network, it may happen that you need to call emergency
number even when you have not inserted the SIM card and the
module is not registered with the network. This is called ‘False’
status of the GSM port. Normally SIM card is inserted and the
module is registered with the network. This is called ‘True’ status of
the GSM port. SIMADO GFX11, supports the emergency dialing
feature for both status of GSM port, just like a mobile handset.
How it works?
• The system supports 4 programmable numbers, which are used
as emergency numbers for dialing. Each number is of 4 digits
maximum.
• The dialed number is compared with numbers programmed in the
emergency number table. If it matches by prefect fit logic then
the number is dialed out from the mobile port.
• The system doesn’t check the Allowed and Denied Lists or
Automatic Number Translation, for dialing the emergency number,
but the GSM port must be enabled.
• Emergency dial in GSM network is explained in detail as below:
• A Mobile station has two intelligent systems within itself viz. the
GSM Engine and the SIM card.
• Both, the GSM engine and the SIM card classify few number
strings as Emergency numbers. Such numbers are dialed by
the module with a specific SET UP message known as
Emergency Call Set Up message.
• These numbers are dialed by the GSM Engine in following
cases:
• Not registered with subscribed Service Providers’ Network.
In such case, the Engine dials the Emergency number
using any other available GSM network.
• When SIM is absent.
