... is the current subject bible.

If there are no T4 events in your network log preceded by 16 T3 events in close order, then the upstream is just about performing correctly. I'd be nervous about such a high upstream power level - it requires that much power to push your upstream data through. Might just be your coax cable needs screwing tighter.
