Okay, here's the answer you've been waiting for from some guy on the
internet in this record-low participation quiz. This URL takes you
directly to the relevant section to save time:

So it turns out that John, Edward and myself were all wrong and only
Jason and Jeroen were right! And the proof is right there in the
video.

I don't see any proof of anything in the section of the video you posted.
I didn't watch the entire video.
Maybe you should post the proof for this example in text and ask why a 30
minute video is needed if a few lines of text is enough.
DOCSIS isn't my field but I would have thought that the average cable
modem
could report whether or not it's happy with the signal levels.
The ISP/Cable company I use ripped the cable and phone lines out and put
fibre to the home into the small town I live in about a year ago.
So DOCSIS is history here.

John knows what I mean as we're both veterans here. I actually agree
with you. The question itself is just plain stupid if the answer
suggests that two absolute quantities added together cannot make an
absolute total.

Pompous twit might be going a bit far but that's what came to mind while I

The guy with the headphones seems embarrassed.

I did manage to find this

I'll add it to my collection of pdfs I've had a quick look through but never
read.

The guy with the phones introduces him as a 50 year veteran of the
cable industry but doesn't set out his precise qualifications, so
perhaps he has none!
Thanks for the link. I save all such documents for off-line reading on
plane flights and such like.
