There is a sticky post in here...but here is the info from there.

Downstream

* Knowsley networks using QAM64 are: -7 to +3 dBmV.

* Knowsley networks using QAM256 are: -3 to +7 dBmV.

* Langley & Bromley networks using QAM64 are: -10 to 0 dBmV.

* Langley & Bromley networks using QAM256 are: -4 to +6 dBmV.

Upstream

* Upstream signal levels (from the modem) should be between 34 and
55dBmV.

So you downstreams are a bit high.
