[852] SYSTEM ALARM ASSIGNMENTS

This MMC allows the assignment of system alarms to ring and display on stations that have an Alarm key assigned. The Alarm key is assigned in MMC 722(Station Key Pro- gramming). Alarm key programming is tenant wide(tenants 1 and 2). Alarms not pro- grammed to report to the system Alarm key will still be retained in the maintenance alarm buffer for Alarm Reporting(MMC 851). The alarm buffer holds up to 100 alarms on a First In-First Out(FIFO) basis. Pressing the Alarm key will silence the audible alarm until an- other alarm is generated by the system. Alarm conditions that have multiple causes(e.g., PRI errors and synchronization loss) will print all associated alarm information if an SIO port is programmed as an ALARM port. The specific fault alarm data can be displayed via MMC 851, System Alarm Reporting.

Alarm Notification

Alarm Notification Off/On(0/1) determines if the alarm provides a visual and audi- ble notification to the System Alarm key station(s). Pressing the System Alarm key and the release key will silence the audible alarm only at the station that pressed the System Alarm key and the release key. See alarm displays table for assignments.
