When enabled, the ATLAS will send Alarm Traps to the each member of the Trap
Destination List upon detecting status bit changes in dsx1LineStatus. Each status
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 the ATLAS will send
an Alarm Trap message. A single Alarm Trap message may report multiple event
changes. The ATLAS clears the event bits after sending the Trap message or send-
ing the response to a Get request for the adDS1LineEvent variable.
