errors on this channel, in the current 15 minute/ current
1 day/ previous 1 day interval.
Performance Data :
Number of packets with NCD (No Cell Delineation)
errors.
Curr15Min/Curr1Day/Prev1Day :

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).

Count of all blocks received with no cell
delineation(NCD) failures in the current 15 minute/
current 1 day/ previous 1 day interval.
Performance Data :

(LCD) failures since agent reset. An LCD failure is
declared when an LCD defect persists for more than 2 -
3 seconds.(length = 4 bytes)
