Enough to make clear my contempt for someone who clearly has no experience in what they are talking about and appears to be some random guy in their parents' basement regurgitating Google alongside some snippets they've picked up in online forums.
Wouldn't be so bad except your wild, baseless and clueless speculation has actively harmed work towards resolutions in this forum. You clearly have no idea what you are talking about, no experience to speak of in the IT field and genuinely just regurgitate what you have learned from reading this forum alongside some ridiculous speculation based on Google.
There are few posters on here more obstructive to the resolution of more complex issues than you posting your clueless, baseless nonsense.
Do take a moment to try and work out a way to explain my post with QoS, CoS or whatever is your current obsession in an attempt to cover up that you have no idea of the basics of networking let alone the finer details of DoCSIS or quality of service managed IP networks.
Comcast run with way more than 16 SC-QAMs. They've 24+ running in many places alongside 4 x 6.4 MHz wide upstreams crammed into the low split 5-42 MHz band.
Yeah I know. I've been reading through the early Docsis 3.1 posts with modem stats and most of those are 16+1 OFDM for some strange reason.
They sell an 'Extreme' 300Mb tier. Selling that on 38 x 16 = 608 Mb of capacity is 'risky' given how intolerant the United States consumers are to visible contention and requires very small nodal areas.
But they're very tollerant to post-rs errors it seems. I've seen many consumers with 33 dB downstream and millions of post-rs without much complaint. Mostly due to the overhead cables perhaps. "My errors increase when the wind blows".
