The following output displays that the hop action succeeded and that a new channel
width has been assigned to the upstream port by the spectrum manager:
The following output displays that the noise power level is restored:

Viewing the Spectrum Management Roll-back Function

When the spectrum roll-back function is enabled, the spectrum manager returns the
upstream channel width or modulation profile setting, that was adjusted during a hop
action, to the original configuration when upstream channel conditions improve.
In the following output example, the roll-back function starts when the ingress noise
is removed:
The following output shows the existing upstream channel width reverting to its
original upstream channel width setting:
