Description: This attribute displays whether the Path Remote Failure Indication (P-RFI) alarm state has been entered. An P-RFI alarm state is entered when Path Remote Defect Indicator (P-RDI) defects have been observed and accumulated for a period of 2.5 seconds +/- 0.5 seconds. The P-RDI defect is the occurrence of the P-RDI signal in five contiguous valid STS or STM frames (bit 5 of the G1 byte set to 1). If the P-RDI defects are intermittently occurring, the P-RDI 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 Path component goes into an operational state of disabled until the P-RFI alarm condition is cleared. The condition is cleared after no P-RDI defect has been detected for 10 seconds +/- 0.5 seconds. The rxRfiAlarm attribute is always set to off when the Path component has been locked and left offline by the operator or when the Path component has been suspended since the parent component has been locked.
