3.2. Configuring the SIM cards
The SIM cards that will be used with MobiLink ISDN 2 GSM must
be
activated
by the corresponding GSM operator. Also, they must
be properly
configured
before insertion in the GSM slot of the
equipment. The configuration of the SIM cards is performed using a
GSM phone.
□
Disable request for PIN code
– If the “PIN Code
Request” option is disabled, you can insert any value in
the “Pin Code” field of the OAM program. When you enter
the correct PIN code, it will be stored in the equipment
memory and afterwards you need no more bother about
PIN code. The MobiLink unit must be connected with the
computer that runs the OAM program thru a serial
connection in order to modify the “PIN Code” (for more
details check the “User manual” for the isdncfg program).
□
Disable GSM services
– most GSM operators assure
several services (redirection of calls, vocal mailbox)
concerning treatment of incoming calls. These are very
useful in case you cell-phone is busy or disconnected; it is
advantageous to use the call forwarding features provided
by the GSM carrier. But when you use the MobiLink ISDN
2 GSM interface together a phone exchange it is generally
better to disable those services, because you perform
them locally with smaller costs.
□
Disable Auto-redialing and Auto-answer
– you
must disable these options, if they are provided by
your GSM operator.
□
Turn off roaming
- international roaming services allows
you to make calls with the same GSM subscription when
you travel in other countries (where the service provider
has signed a signed roaming contract with your GSM
operator). The roaming option should be disabled,
because MobiLink was designed to work with PBX or
ISDN phones in stationary applications. You won’t take it
in overseas trips! If roaming remains enabled, it is
possible that when the local GSM carrier is interrupted,
the ISDN 2 GSM interface will connect to a foreign mobile
operator and the costs of the calls will be much higher.
