### Description

```asn1
lpDS3DS1LofAlarm OBJECT-TYPE
SYNTAX INTEGER {
on(0),
off(1) }
ACCESS read-only
STATUS mandatory
DESCRIPTION
"This attribute indicates whether a LOF (Loss of Frame) alarm state
has been entered. The LOF alarm state is entered when LOF defects
(2 out of 5 framing bits in error ) have been detected for 3 seconds
+/- 0.5 seconds. If the LOF defects are intermittently occurring, the
LOF 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. This tributary goes
into an operationalState of disabled until the LOF alarm state is
cleared. Also, an RAI alarm is transmitted to the far end for the
duration of the LOF alarm state
The condition is cleared when framing has been achieved for 10
seconds +/- 0.5 seconds."
