Description The number of times the CMTS misses the Ranging request from the Cable Modem. The CMTS issues a Station Maintenance packet every 10 seconds and waits for a Ranging request from the Cable Modem. If the CMTS misses a Ranging request within 25 msec then the Miss Object will be incremented. If ccsFlapTotalNum is high, Hit and Miss are high but ccsFlapPowerAdjustmentNum and ccsFlapInsertionFailNum are low then the flapping is probably caused by the modem going up and down. Miss 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 ccsFlapMisses 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 an user resets all the statistical objects for this entry. The value of the object ccsFlapLastResetTime indicates the last reset time.
