Clear Alarm

The Clear Alarm (C A) command set will clear all activity initiated by an alarm: the external alarm hardware will be deactivated (the contact normally open will be reopened), the LED light will go out, an entry will be made in the alarm log of the date and time the alarm was cleared, and line processing will cease (for alarm level 2 only). When this command set is typed in, the MMI will display the message “Alarm acknowledged.” If the alarm condition still exists, the alarm will be declared again.
