> 16.2 | ^SSTN SAT Notification

> Unsolicited Result Codes
> URC 1
> Proactive Command notification
> ^SSTN: <cmdType>
> Every time the SIM Application issues a Proactive Command, via the ME, the TA will receive a notification. This indicates the type of Proactive Command issued.
> AT^SSTGI must then be used by the TA to request the parameters of the Proactive Command from the ME.
> Upon receiving the ^SSTGI response from the ME, the TA must send AT^SSTR to confirm the execution of the Proactive Command and provide any required user response, e.g. a selected menu item.
> URC 2
> Terminate Proactive Command notification
> ^SSTN: <cmdTerminateValue>
> When the SIM application has issued a Proactive Command to the ME, it is possible that this command will be terminated later. URC "^SSTN" is sent with a different Proactive Command type number (added terminate offset 100) to indicate the termination of the specified command.
> The state changes to idle. Therefore the TA should avoid sending any further commands related to the terminated Proactive Command, e.g. AT^SSTGI or AT^SSTR.
> URC 3
> Notification that SIM Application has returned to main menu
> ^SSTN: 254
> Notification to the TA when the SIM Application has finished a command cycle and again enters its main menue, which was transferred with an URC "^SSTN: 37" (SET UP MENU) at start up.
> This URC should be used to open this menue on the sreen.
> The TA does not need to respond directly, i.e. AT^SSTR is not required.
> URC 4
> SIM reset notification
> ^SSTN: 255
> Notification to the TA if a Proactive Command "REFRESH - SIM Reset" has been issued by the SIM Application, please refer to AT^SSTGI.
> This URC should be used to set the TAs application to its initial state since the SIM Application will start from the beginning, too.
> The TA does not need to respond directly, i.e. related AT^SSTGI and AT^SSTR are neither required nor allowed.
> Since the ME is still busy on SIM access the ME may respond with "+CME ERROR: SIM blocked" or "+CME ERROR: SIM busy" on following PIN required AT Commands for a while. Then TA shall retry until the ME responds with "OK". The time needed for this process depends on the SIM and may take more than 10 seconds.
