Advanced Mobile parameters
SIM PUK:
(Optional) If known, the SIM PUK code can be entered in these fields. If the router detects that a
PUK is required due to a locked SIM, this number will be sent to the SIM. A SIM PIN must also be
configured for the PUK parameter to take effect.
Confirm SIM PUK:
Enter the PUK code again in this field to confirm it.
Initialisation string <n>:
These parameters (Initialisation string 1, Initialisation string 2, Initialisation string 3) specify
a number of command strings that are sent to the wireless module each time a wireless
connection is attempted. You can use these parameters to set non-standard wireless operating
modes.
Before being sent to the wireless module, each string is prefixed with the characters AT, then
sent to the wireless module in the order specified until an empty string is encountered. For
example, Initialisation string 3 is not sent unless Initialisation string 1 and Initialisation string 2
are both specified. Initialisation strings are not normally required for most applications as the
router will normally be preconfigured for correct operation with most networks.
Hang-up string:
In a typical wireless application, the connection to the network is always on and under normal
circumstances it is not necessary to hang-up the wireless module. Under certain circumstances
however, the router may use the ATH command to try and disconnect the wireless module from
the network, such as if an incorrect APN has been specified and the module is unable to attach
to the network correctly.
This parameter specifies an alternative hang-up string that is sent to the wireless module when
disconnecting a call. As with the Initialisation strings, it is not necessary to include the AT as this
is inserted automatically by the router
