1. A method for facilitating communications between a network node and a Head End of an access network, the access network including a plurality of nodes which communicate with the Head End via at least one upstream channel and at least one downstream channel, the method comprising:

  • configuring the Head End to utilize a first modulation profile for receiving communication signals from at least one network node via a first channel;

    detecting a change in at least one channel condition on the first channel; and

    dynamically configuring the Head End to use a second modulation profile for receiving communication signals on the first channel, wherein said dynamically configuring is performed in response to the at least one channel condition change being detected on the first channel, and wherein the at least one channel condition chance includes a Forward Error Correction (FEC) factor value change.
