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 ccsCmFlapTotalNum is high, Hit and Miss are high but ccsCmFlapPowerAdjustmentNum and ccsCmFlapInsertionFailNum 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. The value of this object can be reset to zero if this entry is removed from the table and then re-added, or if the ccsCmFlapResetNow object was set to true(1). The value of the object ccsCmFlapLastResetTime indicates the last reset time.
