System Events 21-3Event GenerationAs soon as a message-generating event occurs, a Call Request is automatically sent tothe Primary Alarm Output ID, and the Secondary Alarm Output ID if configured. (Theevent is stored in the originating node's buffer until the event connection is activated.)All events are transmitted in raw data format to the collecting node, which constructsevent messages and sends them to the display device(s).An internal timer limits the time events are kept in the system buffer if the system failsto bring the event connection up. If the timer expires, the buffer is cleared. The eventconnection remains active until the event system detects that there are no eventsoccurring during the time period set for the Line Idle Timer. After the event connectionis cleared, the event system will repeat the above procedures if any events occur.Displaying EventsTo display any local events on the screen as they occur, press [D] at the Main Menu.Event messages will continue to be sent to any destinations specified by the param-eters described earlier in this chapter.While this feature is activated, you cannot perform other operations on thescreen. Also, if the Primary Alarm Output device is unreachable, no localevents will be displayed.A display at a collecting node looks like the example shown below. (A display at asending node will show only that node's events.)Chicago 1008 01/16/1998 08:34:31 end of iplChicago 1013 01/16/1998 08:34:32 L:2 P:2 link PAD failChicago 1004 01/16/1998 08:34:38 L:2 P:0 link X.25 failChicago 1005 01/16/1998 08:34:44 L:2 P:0 restart with cc=7 dc=0Chicago 1006 01/16/1998 08:35:15 L:2 P:0 operationalSt Louis 1008 01/16/1998 08:30:43 end of iplSt Louis 1004 01/16/1998 08:30:50 L1 P:1 link X.25 failSt Louis 450 01/16/1998 08:31:41St Louis 1005 01/16/1998 08:32:24 L:1 P:3 restart with cc=0 dc=0St Louis 1006 01/16/1998 08:32:35 L1 P:3 operationalSt Louis 450 01/16/1998 08:33:01St Louis 1005 01/16/1998 08:33:14 L:1 P:1 restart with cc=0 dc=0St Louis 1008 01/16/1998 08:33:31 end of iplPress [F3] to stop displaying events and return to normal menu operations.
