Ensemble S8: GSM facility lock
Commands
AT+CLCK Facility lock (ver. 5)
Description: Execution command is used to lock, unlock or interrogate an ME or a net-
work facility <fac>. Password is normally needed to do such actions.
When querying the status of a network service (<mode>=2) the response
line for “not active” case (<status>=0) should be returned only if service is
not active for any <class>. This command should be abortable when net-
work facilities are set or interrogated
Call barring facilities are based on GSM/UMTS supplementary services
(refer to 3GPP TS 22.088). The interaction of these with other commands
based on other GSM/UMTS supplementary services is described in the
GSM/UMTS standard.
Test command returns facility values supported by the phone as a com-
pound value.
Note:
• “PS” and <mode>=1 correspond to Auto Lock
• Which <passwd> (PIN-code) that will be used for authentication is
manufacturer specific.
