120M : Can someone explain why cable suffers on upload?

That would be pretty damn good if true!

Telford has a habit of just blindly making stuff up. It won't be true.

Though I do suspect the next tier jumps will be to 60/120/200 but I reckon the upload ratio will remain at 10:1.

Surely not Are you sure about that? Whatever next?

That's about as likely as this:

200/20? As the next top tier?

Most likely yes. Even Docsis 3.1 has a recommended 10:1 ratio, so you'll likely be seeing that ratio for years and years to come.

To be honest, I have yet to see a post from TC which hasnt been truthful, regarding VMs strategies, although 2:1 upstream does seem very far fetched, so did the doubling of download speed, but TC saw that coming much before everyone else

[qasdfdsaq]

Well all VM D3 modems support 4 upstreams and 64QAM

Virgin Media will bring out 50:1 yes they will as they know they cannot remain ratio at 10:1 forever or they will lose business to BT

Err.. You must have skipped maths at school.. You're suggesting their next tier will be 200/4. That's 50:1. LOL. That's more competitive how?

[Chrysalis]

VM need to get back to 10:1 first, last I checked most areas at tiers other than the 120 are not back to 10:1.

If you make random predictions often enough, you will get some right occasionally, like The Daily Express annually predicting the coldest winter for years. I'm just hoping a ratio of 50:1 isn't one of TC's correct ones.

Fair enough, but on the flip side, can you link me to (or even recall) the last time he was wrong?

Not yet case closed but I'm willing to put quite a few bob on the chances that this one is going to prove to be complete and utter BS...
http://www.cableforum.co.uk/board/12...l#post35642660 (it's the 200down 100up by next year prediction)

[craigj2k12]

Innocent until proven guilty, when was the last time he was proven to be wrong?

Seem to remember him predicting the end of VM and that Sky would cap or block P2P. Haven't looked for a link. These sorts or prediction can take a while to mature. So who knows.

Perhaps TC = The new Nostradamus.

[craigj2k12]

Well firstly, a quick google search brings up a few users on the VM forum using QAM64 upstreams, so theres one thing we have evidence of...

http://community.virginmedia.com/t5/...t/true#M135133

Upstream:
US-1 US-2 US-3 US-4
Channel Type 2.0 N/A N/A 2.0

And these guys have a 16QAM and 64QAM upstream:

So from TC's stats, the things I can see no other proof of are:

So the only things I can see out of place is the reduced symbol rate (even the users on the VM forum with QAM64 upstreams have 5120000Sym/sec) and the traffic rates, everything else checks out, so I have no reason to doubt him.
