11-4 ATLAS 800 User Manual 61200180L1-1
When enabled, ATLAS sends alarm traps to the each member of the trap
destination list upon detecting status bit changes in dsx1LineStatus. Each sta-
tus change sets an event bit = 1 in the adDS1LineEvent variable in the DS1
alarm table. If you have previously set the corresponding enable bit = 1 in
the adDS1LineArm variable and adDS1AlarmEnable = On, then ATLAS sends
an alarm trap message. A single alarm trap message may report multiple
event changes. ATLAS clears the event bits after sending the trap message
or sending the response to a Get request for the adDS1LineEvent variable.
DS1 Alert Traps
RFC1406 also defines a series of Current and Total Alert threshold values.
You can enable ATLAS to send an alert trap message to each member of the
trap destination list when accumulated error statistics exceed these thresh-
old values. Table 11-4 describes the alert traps supported by ATLAS for
events that have occurred in the last 15-minute interval.
