Curr15Min/Curr1Day/Prev1Day :

 

Count of all encoded blocks received with uncorrected

 

errors on this channel, in the current 15 minute/ current

 

1 day/ previous 1 day interval.

 

 

NCD Count

Performance Data :

 

Number of packets with NCD (No Cell Delineation)

 

errors.

 

Curr15Min/Curr1Day/Prev1Day :

 

Number of packets with NCD error, received in the

 

current 15-minute/ current 1-day/ previous 1-day

 

interval.

 

 

HEC Count

Performance Data :

 

Number of packets with HEC error.

 

Curr15Min/Curr1Day/Prev1Day :

 

Number of packets with HEC error received in the

 

current 15 minute/ current 1 day/ previous 1 day interval.

 

 

NCD Failure Count

Performance Data :

 

Count of all blocks received with no cell delineation

 

(NCD) failures since agent reset. An NCD failure is

 

declared when an NCD defect is present for 2-3

 

seconds after SHOWTIME.(length = 4 bytes).

 

Curr15Min/Curr1Day/Prev1Day :

 

Count of all blocks received with no cell

 

delineation(NCD) failures in the current 15 minute/

 

current 1 day/ previous 1 day interval.

 

 

LCD Failure Count

Performance Data :

 

Count of all blocks received with loss of cell delineation

 

(LCD) failures since agent reset. An LCD failure is

 

declared when an LCD defect persists for more than 2 -

 

3 seconds.(length = 4 bytes)

 

Curr15Min/Curr1Day/Prev1Day :

 

Count of all blocks received with loss of cell delineation

 

(LCD) failures in the current 15 minute/ current 1 day/

 

previous 1 day interval.
