Near End Severely Errored Seconds (imaLinkIntervalNeSevErroredSecs)

Number of 1-second intervals containing greater than or equal to 30 per cent of the ICP cells counted as IV-IMAs, or one or more link defects in one of the previous 96 intervals of 15 minutes each.


Far End Severely Errored Seconds (imaLinkIntervalFeSevErroredSecs)

Number of 1-second intervals containing one or more RDI-IMA defects in one of the previous 96 intervals of 15 minutes each.

 


Near End Unavailable Seconds (imaLinkIntervalNeUnavailSecs)

Number of unavailable seconds at the near-end in one of the previous 96 intervals of 15 minutes each. 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 (imaLinkIntervalFeUnavailSecs)

Number of unavailable seconds at far-end in one of the previous 96 intervals of 15 minutes each.


Near End Tx Unusable Seconds (imaLinkIntervalNeTxUnusableSecs)

Number of unusable seconds at near-end Tx LSM in one of the previous 96 intervals of 15 minutes each.


Near End Rx Unusable Seconds (imaLinkIntervalNeRxUnusableSecs)

Number of unusable seconds at the near-end Rx LSM in one of the previous 96 intervals of 15 minutes each.


Far End Tx Unusable Seconds (imaLinkIntervalFeTxUnusableSecs)

Number of seconds with Tx unusable indication from the far-end Tx LSM in one of the previous 96 intervals of 15 minutes each.


Far End Rx Unusable Seconds (imaLinkIntervalFeRxUnusableSecs)

Number of seconds with Rx unusable indications from the far-end Rx LSM in of the previous 96 intervals of 15 minutes each.

 


Near End Tx Failures (imaLinkIntervalNeTxNumFailures)

Number of times a near-end transmit failure alarm condition has been entered on a link in one of the previous 96 intervals or 15 minutes each.

 


Near End Rx Failures (imaLinkIntervalNeRxNumFailures)

Number of times a near-end receive failure alarm condition has been entered on a link in one of the previous 96 intervals of 15 minutes each.

 


Far End Tx Failures (imaLinkIntervalFeTxNumFailures)

Number of times a far-end transmit failure alarm has been entered on a link in one of the previous 96 intervals of 15 minutes each.


Far End Rx Failures (imaLinkIntervalFeRxNumFailures)

Number of times a far-end receive failure alarm has been entered on a link in one of the previous 96 intervals or 15 minutes each.

 


Tx Stuffs Inserted (imaLinkIntervalTxStuffs)

Number of stuff events inserted in the transmit direction in one of the previous 96 intervals of 15 minutes each.


Rx Stuffs Inserted (imaLinkIntervalRxStuffs)

Number of stuff events detected in the receive direction in one of the previous 96 intervals of 15 minutes each.
