This is the total number of ICP Violations including the number of errored, invalid or
missing ICP cells, except during an SES (Severely Errored Seconds) or a UAS
(UnAvailable Seconds) condition.
OIF (Out of IMA Frame) is the occurrence of IMA anomalies.
This is the number of OIF anomalies, except during SES or UAS conditions.
This is the number of one-second intervals with greater than 30% of the ICP cells
counted as IV (ICP Violation) or one or more link defects (such as LOS (Loss Of Signal) or
LOF (Loss Of Frame)), LIF (Loss of IMA Frame defect), or LODS (Link Out of Delay
Synchronization defect) defects, except during UAS conditions.
This is the number of one-second intervals containing one or more RDI (Remote Defect
Indicator) defects, except during UASFE conditions.
This is unavailable seconds detected by the IMA line card.
This is unavailable seconds detected by the remote IMA device.
This is the number of link-layer transmission (Tx) or receiving (Rx) failures detected by
the IMA line card.
This is the number of link-layer transmission (Tx) or receiving (Rx) failures detected by
the remote IMA device.
This is the number of unusable seconds in the transmission (Tx) or receiving (Rx)
direction detected by the IMA line card.
This is the number of unusable seconds in the transmission (Tx) or receiving (Rx)
direction detected by the remote IMA device.
This is the number of stuff events the IMA line card has inserted on the link in the
transmission (Tx) or receiving (Rx) direction. Stuff events are inserted on a link when
the delay of the link is out of tolerance in the IMA group.
