ccsFlapCrcErrorNum 1.3.6.1.4.1.9.9.114.1.1.5.1.16

The number of times the CMTS upstream receiver flagged a packet with a CRC error. If ccsFlapCrcErrorNum 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 object 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. This object is going to replace the object ccsFlapCrcErrors and the value of this object can be reset to zero if this entry is removed from the table and then re-added, or if a user resets all the statistical objects for this entry. The value of the object ccsFlapLastResetTime indicates the last reset time.
