Abstract
A technique is disclosed for facilitating communications between a network node and a Head End of an access network. The access network includes a plurality of nodes which communicate with the Head End via at least one upstream channel and at least one downstream channel. The Head End is configured to monitor channel conditions on selected channels of the access network. The Head End is also configured to modify or change the modulation profile used on a selected channel in response to detecting a change in conditions on that particular channel. If the Head End detects that the channel conditions have deteriorated, the Head End may change the modulation profile on the selected channel to one which is better suited for transmitting data on the channel given the current channel conditions. If the Head End detects that the channel conditions have improved, the Head End may change the modulation profile on the selected channel to one which provides for faster data transmission on the selected channel.
