no, i still dont understand where the reported power levels come into it. Where does the 21 or 23 come into it which we start off with (is that from the cmts?) and as we assuming that we star off at 0 do we then add the reported power levels to the +3? Can you do a worked example based on an average of 8dBmv over 8 channels which is what I think the op has.

And putting my confusion about the reported power levels aside, are you saying that in order for VM to ever use a 16 channel modem that the power levels would have to be 0? (21 +(4x3))=33
