IMSI –
it shows in fact the IMSI (International Mobile Subscriber Identity) code that is
specific to the subscriber, therefore to the Sim card used in the SS Telecoms
equipment.
If the Mobile module of SS-16 detects an active SIM card, it will query (and display)
the IMSI code. Since the IMSI code is related to the SIM, when changing the SIM
card used with the respective GSM module, the user will have another IMSI code.
IMEI
- the International Mobile Equipment Identifier is a 15-digit number that uniquely
identifies an individual mobile terminal wireless device. While IMSI is specific to the
subscriber (SIM card), IMEI is specific to the equipment (cellular modem of SS-16
VOIP-2-GSM)
If the SIM card is missing, the SIM Status window will show “error” in the fields PIN,
IMSI, Signal Level, Network and respectively Registration.
But the user will still see the IMEI code, since it is equipment-dependent, and not
related to the SIM card.
Signal Quality
-
The level of the signal received from the mobile network.
At the bottom there is a “Load” button again - click it to refresh the display of module’s
status. This way one is sure to see the current state of the mobile module and
subscriber information!
Notes:
To be able to display the current state, the respective mobile module must
NOT
be in
a call!
When the GSM module is routing a VoIP call, or transmitting an SMS message, it will
no longer be available for status
interrogation
, so it will display “Busy”:
This does not mean something is wrong, simply that the module is unavailable for
status
interrogation
.
Try again (click “Load”) later, when finished with the voice call or the transmission of
SMS messages.
