Description (partial)

In the output of the command "show cable hop" on the CBR8 the output for the "Corr FEC" and Uncorr FEC" always remain at 0 for US channels of an RPD.
This becomes a problem if the customer configures dynamic modulation for RPD and wants to use these values.

The issue is always present but only becomes a problem when dynamic modulation is used for RPD and FEC needs to be used as trigger modulation changes.
