What Are They?
These errors are counts of errors each card observes on the polling bus. The polling bus is a unidirectional bus
from each Broadband Controller Card (BCC) to all the other cards in the shelf. It is a shared resource.
from each Broadband Controller Card (BCC) to all the other cards in the shelf. It is a shared resource.
What Do They Mean?
These errors indicate a problem with the BCC, backplane, or one of the cards sitting on the bus. If they occur
on only one card, that card is most likely to have the problem. As the card will ignore the polling cycle that
had a parity error, these errors can lead to Bad Grant errors, which result in cell losses.
