Open in standard view

This table contains statistics related to Advanced Spectrum
Management's Frequency and Modulation Agility feature
          
This table applies to all CMTS card types.
          
For CMTS 2x8 cards, frequency and modulation agility
hop decisions are made on the basis of SNR measurements.   
For older, 1x8 and 1x4 cards, hop decisions are made on the 
basis of error thresholds, or modem flapping.
          
This table displays all upstream channels, regardless of whether
they members of spectrum groups, or not.   Agility actions
can take place only for those channels belonging to spectrum
groups that have hop actions configured.
