The return to the headend is 5 to 50mhz used for cable modem, phone and VOD access. Most systems try to stay away from using the return for video these days because it never seems to work well due to noise. The lowest channel used for forward is channel 2. Almost all cable systems use all the channels they can. Even the HAM bands etc... the FCC will shut us down if we have leakage over a set amount. Where I work we use every channel on the 750Mhz systems from ch2 to 117.
