Re: [TWC] Possible problem with new Zoom 5341j

Here are my upstream numbers right now:

Upstream Bonding Channel Value
Channel ID 6 5
Frequency 23800000 Hz 19000000 Hz
Ranging Service ID 14033 0
Symbol Rate 5.120 Msym/sec 2.560 Msym/sec
Power Level 45 dBmV 45 dBmV
Upstream Modulation [3] QPSK
[3] 16QAM
[3] QPSK
[2] 16QAM

Ranging Status Success Success

Is there any way for me to tell if noise is the issue or will I need a tech to come here?

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.

Ah nice I did not know that, well it may still be difficult to get the right person to do a spectrum analysis, but that is my experience so far, TWC is hard to actually get to fix issues that aren't apparent to them.
