ISU AT Command Reference Phase VII AT Commands
Iridium Proprietary Version 2.45
20 June 2011 96
<classx> is a sum of integers each representing a class of information:
1 voice
2 data
4 fax
This parameter defaults to 7, equal to all classes, but the ISU only supports Voice Call Barring so this
is illegal. Therefore in practice the DTE must supply <classx>=1 when querying or changing the
status of any Call Barring facility. When querying (<mode>=2), <passwd> is irrelevant and should be
supplied as ”” in order to allow the <classx>=1 parameter to be supplied.
For facilities “CS”, “SC”and “FD”, the <passwd> and <classx> parameters are not relevant and will be
ignored if supplied.
Test Command: +CLCK=?
Test command returns the facility values supported by the phone. The response is in the form:
+CLCK:(list of supported <fac>s)
Note: Only “CS” will appear as a supported value if there is no SIM card in the device.
Note: +CLCK is closely related to +CPIN and +CPWD. See these commands for additional information.
11.7 +CPWD - Change Password (9555/9522B version)
This is an extended version of the Phase II +CPWD command (section 6.20).
Exec Command: +CPWD=<fac>,<oldpwd>,<newpwd>
This command sets a new password for the facility lock function defined by the AT command Facility
Lock +CLCK . The following parameter values are currently supported:
<fac>:
“CS” CNTRL Surface (Phone Unlock Code)
“SC” SIM (SIM Card PIN Code)
“P2” SIM PIN2 (SIM Card PIN2 Code)
“AB” Call Barring password (single password used for all call barring supplementary services)
Note: AT+CPWD=”SC”,<oldpwd>,<newpwd> will return “Error” unless the SIM Card Pin Code is
currently activated (see AT command Facility Lock +CLCK).
Note: A user interface may prompt the user for two copies of the new password, in which case it should
check the two are identical as only one copy is needed for this command.
Test Command: +CPWD=?
Test command returns a list of pairs which present the available facilities and the maximum length of their
password. Response is in the form:
+CPWD: list of supported (<fac>,<pwdlength>)s
where <pwdlength> indicates the maximum length for the password.
Note: +CPWD is closely related to +CLCK and +CPIN. See these commands for additional information.
