### 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.
