column deprecated SNMPv2-SMICounter32

The number of times the CMTS upstream receiver flagged
a packet with a CRC error.
              
If ccsFlapCrcErrors is high, it indicates the cable
upstream may have high noise level.  The modem may not be
flapping yet but it may be a potential problem.
              
This count can indicate:
    Intermittent upstream,
    Laser clipping, or
    Noise bursts.
              
Laser clipping can happen if the signal power is too high
when the upstream electrical signal is converted to an
optical signal.  When it happens the more input produces 
less output, until finally there is no more increase in 
output.  This phenomena is called laser clipping.
Discontinuites in the value of this counter can occur if
this entry is removed from the table and then re-added, and
are indicated by a change in the value of
ccsFlapCreateTime.
