Description: This variable shows the status of each alarm by
setting a bit.  If the bit is set the alarm is
active.  Multiple bits can be set at one time.

Bit #   ALARM
------  -----
0x01    LOS
0x02    Red
0x04    Yellow
0x08    Blue
0x10    DS0

What is adATLAST1IfAlarmStatus?

This OID stores a bitmask representing which alarms are currently active on the T1 interface, with separate bits for Loss-of-Signal (LOS), Red, Yellow, and Blue alarms. Engineers monitor this to detect immediate line problems and diagnose whether the T1 link is experiencing signal loss or degradation. For example, a value of 0x03 means both the LOS alarm and Red alarm are active, indicating the link has lost signal and is in alarm state.
