mscLpDS1RxRaiAlarm 1.3.6.1.4.1.562.36.2.1.12.7.16.1.4

This attribute displays whether an RAI (Remote Alarm Indication) alarm state has been entered. An RAI alarm state is entered when the RAI defect indicator has been observed and accumulated for 3.5 seconds +/- 0.5 seconds. For 3pDS1Atm, and 8pDS1Atm cards: alarm is declared immediately upon observing the defect is present, with no integration time. For 3pE1Atm, and 8pE1Atm cards: alarm state is entered when the RAI defect indicator has been observed and accumulated for 2.5 seconds +/- 0.5 seconds. If the RAI defects are intermittently occurring, the 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 RAI alarm state is cleared when the RAI defect indicator has been absent for 10 seconds +/- 0.5 seconds (for 3pDS1Atm, and 8pDS1Atm cards: alarm is cleared immediately upon observing the defect is absent, with no integration time). The RAI alarm is usually an indication that the far end facility is unable to gain synchronization.
