Spectrum hopping rules determine the action taken when the spectrum manager
decides to change the parameters of an upstream channel to combat noise.
Operators can improve upstream channel conditions to combat ingress noise by
specifying hopping rules for upstream frequency changes, upstream frequency
band changes, modulation profile changes, channel-width reduction (until
channel conditions improve), and power adjustments (if it is necessary).

Defining a spectrum group contains the following tasks outlined in this section:

■

Creating a Spectrum Group

■

Scheduling the Availability of a Spectrum Group Band

■

Scheduling the Removal of a Spectrum Group Band

■

Configuring Spectrum Data Collection

■

Configuring Spectrum Hopping Rules

■

Configuring the Spectrum Hopping Error Threshold

■

Configuring the Spectrum Hopping Flap Threshold

■

Enabling and Disabling Spectrum Roll-back

■

Configuring the Guard Band

■

Reviewing the Spectrum Group that You Created

Creating a Spectrum Group

Follow these steps to create a cable spectrum group:

1.

Use the

cable spectrum

command in Global Configuration mode to create a

cable spectrum group and enter the new mode in which to configure your cable
spectrum group:

MOT(config)#

cable spectrum

<

WORD

>

where:

WORD

is the spectrum group name.

Note:

No spaces are allowed for the spectrum group name.
