Modulation Profile
The Profile Index number that identifies the properties of the Upstream
Channel ID.
You assign a modulation profile to an upstream channel by performing the
following tasks.
Data-Backoff
The data-backoff parameter sets a fixed start value for initial data backoff on
the upstream channels. By default, the TX data backoff Start parameter is set
to 5. Acceptable values are 0 to 15.
You set the data backoff range on the upstream channel by performing the
following task.
