1. A method of using a physical upstream receiver, the method comprising:

  • in a normal mode, assigning a first set of parameters to the physical receiver for communicating with cable modems in a first frequency;

    in a lookahead mode, assigning a second set of parameters to the physical upstream receiver for communicating with a device in a second frequency, the second frequency being different from the first frequency;

    determining whether the second frequency should be used to communicate with the cable modems; and

    performing transitions between the normal mode and the lookahead mode periodically.
