This attribute displays whether a Loss Of Frame (LOF) alarm state
has been entered. An LOF alarm state is entered when Severely
Errored Frame (SEF) defects have been observed and accumulated
for a period of 2.5 seconds +/- 0.5 seconds. A SEF defect is
detected when 3 (or more) out of 16 (or fewer) F-bits are in error, or
one (or more) M-bits in two (or more) out of four (or fewer)
consecutive M-frames are in error. 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.
The DS3 component goes into an operational state of disabled until
the LOF alarm condition is cleared. The condition is cleared when
framing has been achieved for a period of 10 seconds +/- 0.5
seconds. As long as SEF defects are detected, the node also
transmits the far-end SEF/AIS defect indicator over the outgoing
line. When not running in C-Bit Parity mode, the txRai attribute is
also set to on when transmitting the far-end SEF/AIS defect
indicator on the outgoing line.
The lofAlarm attribute is always set to off when the component has
been locked and left offline.
