ISU AT Command Reference Phase VII AT Commands
Iridium Proprietary Version 2.45
20 June 2011 95
Command is abortable in the cases when network facilities are set or interrogated. The interaction of this
command with other commands based on other GSM supplementary services is described in the GSM
standard.
Execute command is used to activate or deactivate Call Barring Supplementary Services, SIM Fixed
Dialling feature, the SIM card PIN Code, or to enable or disable the Phone Lock feature in the ISU. A
password code (detailed below) may be required, depending on the action chosen.
Not all Call Barring services detailed in GSM 07.07 subclause 7.4 are supported. A subset of those
implemented in the H1 menu MMI is supported.
Note: This command will not work unless the SIM PIN has been entered using the +CPIN command.
Note: Once this command has been issued to disable the PIN, neither it nor the +CPIN need to be issued again
unless the PIN function is reactivated.
The following parameter values are currently supported:
<fac>:
“CS” CNTRL Surface (Enable/Disable Phone Lock feature). The current Phone Unlock Code
is required as <passwd>.
“SC” SIM: Activate/Deactivate SIM card PIN Code, in which the SIM asks password in ME
power-up. The PIN code is required as <passwd>.
"FD" SIM fixed dialling memory feature (PIN2 is required as <passwd>)
"AO" BAOC (Bar All Outgoing Calls) (refer GSM 02.88 [6] clause 1). The Call Barring
password is required as <passwd>.
"AI" BAIC (Bar All Incoming Calls) (refer GSM 02.88 [6] clause 2). The Call Barring
password is required as <passwd>.
"AB" All Barring services (refer GSM 02.30 [19]) (applicable only for <mode>=0). The Call
Barring password is required as <passwd>.
Note: several GSM standard facility codes including the following are NOT supported:
"OI" BOIC (Bar Outgoing International Calls) (refer GSM 02.88 [6] clause 1). All Iridium
calls are International, so this facility should not be exercised by a user interface.
"OX" BOIC-exHC (Bar Outgoing International Calls except to Home Country) (refer GSM
02.88 [6] clause 1). All Iridium calls are International, so this facility should not be
exercised by a user interface.
"IR" BIC-Roam (Bar Incoming Calls when Roaming outside the home country) (refer GSM
02.88 [6] clause 2). In Iridium it is not possible to roam (there is only one “home
country”), so this facility should not be exercised by a user interface.
"AG" All outGoing barring services (refer GSM 02.30 [19]) (applicable only for <mode>=0).
This subgroup of services cannot be addressed; the user interface should just use “AB”.
"AC" All inComing barring services (refer GSM 02.30 [19]) (applicable only for <mode>=0).
This subgroup of services cannot be addressed; the user interface should just use “AB”.
<mode>:
0 Disable (Deactivate)
1 Enable (Activate)
<passwd>: string type, enclosed by “ “; for example, “1234”.
Note: Factory default SIM card PIN Code is “1111”
Note: Factory default Phone Unlock Code is “1234”
