Link Violations (imaLinkImaViolations)

Indicates the ICP violations including a count of erred, invalid, or missing ICP cells except during SES-IMA or UAS-IMA conditions.

Oif Anomalies (imaLinkOifAnomalies)

Specifies the number of OIF anomalies at the near-end, except during SES-IMA or UAS-IMA conditions.

Near End Severely Errored Seconds (imaLinkNeSevErroredSecs)

Specifies the number of 1-second intervals containing greater than or equal to 30 per cent of the ICP cells counter as IV-IMAs, or one or more link, LIF, or LODS defects, except during UAS-IMA condition.

Far End Severely Errored Seconds (imaLinkFeSevErroredSecs)

Species the number of 1-second intervals containing one or more RDI-IMA defects, except during UAS-IMA-FE condition.

Near End Unavailable Seconds (imaLinkNeUnavailSecs)

Number of unavailable seconds at the near end. Unavailability begins at the onset of 10 contiguous SES-IMA and ends at the onset of 10 contiguous seconds with no SES-IMA.

Far End Unavailable Seconds (imaLinkFeUnavailSecs)

Number of unavailable seconds at the far-end. Unavailability begins at the onset of 10 contiguous SES-IMA-FE and ends at the onset of 10 contiguous seconds with no SES-IMA-FE.

Near End Tx Unusable Seconds (imaLinkNeTxUnusableSecs)

Number of Tx unusable seconds at the near-end Tx LSM.

Near End Rx Unusable Seconds( imaLinkNeRxUnusableSecs)

Number of Rx unusable seconds at the near-end Rx LSM.

Far End Tx Unusable Seconds (imaLinkFeTxUnusableSecs)

Number of seconds with Tx unusable indications from the far-end Tx LSM.

Far End Rx Unusable Seconds (imaLinkFeRxUnusableSecs)

Number of seconds with Rx unusable indications from the far-end Rx LSM.

Near End Tx Failures (imaLinkNeTxNumFailures)

Number of times a near-end transmit failure alarm has been entered on a link.

Near End Rx Failures( imaLinkNeRxNumFailures)

Number of times a near-end receive failure alarm has been entered on a link.

Far End Tx Failures (imaLinkFeTxNumFailures)

Indicates the number of times a far-end transmit failure alarm has been entered on a link.

Far End Rx Failures (imaLinkFeRxNumFailures)

Number of times a far-end receive failure alarm has been entered on a link.

Tx Stuffs Inserted (imaLinkTxStuffs)

Number of stuff events inserted in the transmit direction.

Rx Stuffs Inserted (imaLinkRxStuffs)

Number of stuff events detected in the receive direction.
