Upstream Receive Power Levels
Upstream channels connected to a single physical connector may vary in channel width and power levels as long as the
variance falls within a user-configured power level group. The tables below describe the three power level groups. All of
the power levels for all of the channels connected to a single physical connector must fall within the same table.

Note: All upstream Rx (receive) values are measured in dBmV. Power after attenuation may vary slightly from one CAM to
another. Power Level Group 1 supports a total input power of 29 dBmV.
