Your signal as far as I can tell is fine, but you can't see the upstream SNR, which has to be read as an average at the CMTS. I bet this problem will take a very long time to fix, since it isn't something that can be easily seen by TWC. Not even a house tech can see the upstream SNR, so sending one of those out will just waste time. I guess you can try to call Tier 3 and see what they can do, but I doubt they will do much.
actually yes a house tech can see the upstream snr they just have to have their spectrum analyzer tool set to the upstream channels if they are programmed into it.
