Figure 5 shows a dialog (User Control Mode -> Settings -> Security) where
security settings can be configured with Nokia 12 Configurator.
5.2.1 Authorised numbers
Authorised number selection limits the access to specific phone numbers only
in the Remote I/O control. Only control messages originating from an
authorised number are allowed to control the Nokia 12 GSM Module and the
device attached to it.
It is possible to define up to 16 authorised numbers. The first number on the
authorised phone number list is in bold (see Figure 5) and is the phone number
of the main user. The main user will be notified of any unauthorised control
attempts.
The following message will be sent to the main user if there is an unauthorised
control attempt:
Unauthorized Number:
Number: X
Command: Y
X is the phone number of the originator of the control message, and Y is the
command that was attempted. If the length of a command or alias is too long to
be shown in one message (more than 160 characters), it will be sent as several
messages.
The phone numbers in the authorised number list may contain digits 0-9 and
the “+” character (ASCII range 0x30-0x39 and 0x2B), for example,
+1234567890, for a maximum length of 32 characters.
Note: The phone numbers in the authorised number list should be defined in
international format with a plus sign, country codes, etc. Note that the Nokia 12
GSM Module needs to receive and identify the number to recognise it as
authorised. Contact your network service provider for details.
