Pre-Installation - ITS Telecom CGW-I Installation And Operation Manual

2.3. Pre-Installation

Your CGW-I device contains a GSM engine. It therefore needs a SIM card
from the local GSM network provider. Its registration to the GSM operator is
similar to the registration of a mobile GSM phone.
Note:
Before installing the SIM card, we recommend disabling all Call Forwarding modes (in the
events of busy, absence, unavailability, etc.) and Call Waiting from the GSM operator.
The PIN code requests on the SIM must be disabled to complete the initial
installation. You can disable the SIM with any GSM mobile phone.
If you enable the PIN after installation using your mobile phone, you must
enter the PIN in the Channel Settings screen (see page 33) before you can
make changes to the CGW-I and so that it will work after power up and
reset. If you enter an incorrect PIN three times in the Channel Settings screen
and are locked out by the SIM, you must enter the PUK code to unlock the
SIM.
Note:
To get the PUK code number, you must call your network operator (i.e., local GSM
Service Center). Once you enter the PUK code and unlock the SIM, you must still enter
the correct PIN to use the CGW-I.
