### Description

```asn1
mscLpDS3LosAlarm OBJECT-TYPE
SYNTAX INTEGER {
on(0),
off(1) }
ACCESS read-only
STATUS mandatory
DESCRIPTION
"This attribute displays whether a Loss Of Signal (LOS) alarm state
has been entered. An LOS alarm state is entered when LOS defects
have been observed and accumulated for a period of 2.5 seconds +/-
0.5 seconds. An LOS defect is detected at the DS3 line interface
upon observing 175 +/- 75 continuous pulse positions with no
pulses of either positive or negative polarity. If the LOS defects are
intermittently occurring, the LOS defect accumulator is
decremented at a rate of 1/10 of the incrementing rate (alarm
integration ratio of 1/10), with all measurements based on a 200 ms
polling cycle.
The DS3 component goes into an operational state of disabled until
the LOS alarm condition is cleared. The LOS alarm state is cleared
after LOS defects have been absent for a period of 10 seconds +/-
0.5 seconds.
The losAlarm attribute is always set to off when the component has
been locked and left offline."
