Upstream and downstream gross bit rates (bits in the air) are defined by the
constellations and symbol rates, as follows:
where, 1 and 2 correspond to bands 1 and 2 of the upstream or downstream signal, and
where the symbol rate is a multiple of 67.5 Kbps.
When setting bit rates, ensure that the following is always true:
