Object
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 Misses count will be incremented.
If ccsFlapTotal is high, Hits and Misses are high but
ccsFlapPowerAdjustments and ccsFlapInsertionFails are
low then the flapping is probably caused by the modem
going up and down.
Miss counts 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.
