Description: This object defines the configuration of the system-wide alarm cut-off (ACO) button. It could be UMC_Mode, Standard_Mode, or Extended_Mode ACO operation. In the UMC_Mode, one push of the ACO button results in the cut-off of the current alarms and the clearing of the Plug-and-play current alarm conditions. The Plug-and-play alarms are Missing Card Alarm, Loss of Composite Clock Alarm, Loss of A/B Power Lead Alarm, Unexpected RSU Registration Alarm. In Standard_Mode mode, the ACO button operates as a traditional ACO and only cuts off audible alarms. The Plug-and-play alarms can only be cleared via the Craft User interface or the restoration of the event that caused the alarm. In the Extended_Mode ACO the ACO button has two time thresholds, a short one, and a long one. A short depression of the ACO button results in alarm cut-off, but it does not clear the plug and play alarms. A long depression of the ACO button results in the alarm cut off and the clearing of plug and play alarms.
