Description: This bit map variable indicates state changes in the DS1 line status variable (dsx1LineStatus). When a line status bit changes state, the corresponding line event bit is set in this variable. If armed, setting the event will generate an Alarm Trap. After reporting the events in an Alarm Trap or Get response, the device clears the reported events.

The various alarm event bit positions are: 1 No Alarm Present 2 Far end LOF ( a.k.a., Yellow Alarm ) 4 Near end sending LOF Indication 8 Far end sending AIS ( Blue Alarm ) 16 Near end sending AIS 32 Near end LOF ( a.k.a., Red Alarm ) 64 Near end Loss Of Signal 128 Near end is looped 256 E1 TS16 AIS 512 Far End Sending TS16 LOMF 1024 Near End Sending TS16 LOMF 2048 Near End detects a test code 4096 any line status not defined here
