This attribute displays whether a multiframe RAI (remote alarm
indicator) alarm state has been entered. A multiframe RAI alarm
state is entered when a multiframe RAI alarm indicator (bit 6 of
timeslot 16 in frame 0 is set to a one) is observed and accumulated
for 2.5 seconds +/- 0.5 seconds. If the multiframe RAI indicator is
intermittently received, the multiframe RAI 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 multiframe RAI alarm condition is cleared when the
multiframe RAI alarm indication is not received for 10 seconds +/-
0.5 seconds. The multiframe RAI alarm is usually an indication that
the far end facility is unable to gain multiframe synchronization.
The 8pE1Atm card does not support the multiframe RAI alarm.
