    Lost MDD is generally a downstream issue, as is the RCS error (the R, incidentally stands for ‘received’, ie what the hub is getting). All I can tell from what you have posted is that one upstream channel has dropped to 32 QAM (however it is the 23.6 MHz channel which is renown for being susceptible to interference) but, that, in itself isn't worth losing sleep over.

    T3 errors aren’t too unusual, one or two a day is fine, if you are only getting one upstream channel, then, yes that is a serious problem, but if it is now back to the usual five, then fine. Remember that on startup the hub will only have a few channels locked which provide it with the information it needs to lock onto the others (slightly simplified, but still).

    And in answer to your last point, you can’t. The hub automatically ramps up the power until the other end (the CMTS) confirms that it is receiving it loud and clear.
