spectrum-group 3
Troubleshooting Tips
To troubleshoot the configuration, make sure you have entered a valid spectrum group number and type.
Configuring and Activating Spectrum Groups
After you create a spectrum group, you need to configure a list of upstream frequencies and optional
nominal power levels that each spectrum group can use when an upstream frequency change is necessary.
Each spectrum group should have its own list of upstream frequencies. Valid frequencies are 5,000,000
to 42,000,000 Hz; valid power levels at a channel width of 1.6 MHz are –10 dBmV to 25 dBmV.
