Thanks for that. So you were previously on two upstreams and now you're on one. You've got 8 downstreams and so prolly your area was thoght by VM to be close to upgraded.

But then, I speculate, problems appeared on the upstream. Most likely one channel was impaired and the CMTS needed 49 dBmv to get the data from your modem. So they've reverted pro tem to one channel and the power level has settled down.

It's spot on. The nominal target is 0 dBmv DS/40 dBmv US and they try to equalise things at the street cabinet amplifier to achieve this. Your US is as much below 40 as your downstream is above. So that's good.

Now to the utilisation question. Without going into the full technicalities, each downstream channel is capable of 55 meg. If you're on 60 meg, it would need less than 8 downloaders at full speed to saturate the downstream capacity on the 8 frequencies that are shared.

Similarly with the upstream, where one channel has 9 meg capacity. If VM were upgrading properly then you shouln't have congestion. If they haven't finished upfrading, they could have swung some cables onto your UBR.
