That is so wrong it's just not funny. Mods please delete this?

:-) that's funny, I was thinking the same thing!! There's just so many to choose from, and I keep losing those pesky DVD's....

Apparantly a turbo button is to be introduced to temporarily speed up your connection.

You sure? According to that link, NTL appear to think that they can squeeze up to 50 Mb from the cable network using DOCSIS 3. And, I suspect, as more efficient encoding methods are introduced, the network will have the bandwidth available to surpass that..

to CableForum BTW.

VDSL is yet another option amongst many.

Why delete it?
I'm interested to know what the actual capacity of the infrastructure is, would you like to explain why you think it's wrong?

dev · 08-08-2005, 12:29

any mention of a cost or if the cap is a hard limit one?

Certainly, cable downstreams are a broadcast architecture, that bit of coax is simulataneously carrying 27+Mbit of DOCSIS traffic, even if some of it is padded empty frames, along with all the DTV, analogue, and out of band.

Existing ntl network build specs up to 860MHz, with the range between 5 and 65MHz being used for upstream traffic, that leaves after a guard band of 20MHz the 85-860MHz band to be used for downstream cable traffic.

At nominal 64QAM 6 bits per symbol and assuming a symbol rate of 0.8Megasymbols/MHz just for the sake of argument that gives 775 x 0.8 x 6 = 3.72Gbps capacity, this can be increased further through 256QAM, 8 bits/symbol.

That's just an approximation with regard to Msymbols/MHz, to illustrate.

On one hand this news is great, and it's very exciting, the prospect of having 10mb, something that parts of Europe have had for years, and i've always been jealous of.

But, on the other hand i'm really not sure that very many of us could actually USE that much speed. 10mb will roughly be about 1250k/sec.

How many ntl customers could actually use up that much bandwidth? And if they do find things that take advantage of it, it's really going to bugger up any ideas of a low cap. If people start using things like streaming live tv, concerts, online dvd rentals etc, they'll soon run out of useage for that month.

I'm not knocking it, i am excited about the upgrade, and i'll be on here like everyone else waiting for the details of when it starts, and how to jump the queue etc. But i just wonder in reality, will many of us actually get to use it in a way that we really experience a difference.

IanUK · 08-08-2005, 13:06

I'm not knocking it either, but I'm really concerned about the Proxies, Poplar can't even handle 3 meg, what hope does it have with 10mb ?

MysticKiller · 08-08-2005, 13:08

So when can I as a 300k cutomer get 10mb? and what will the cap be? 5gb/month? I'm sure it would be something ridiculous like it is on 1mb lol.

Virtually all customers could use the 10 mbps and more if you think about it. Streaming tv such as live football matches and films may quickly use up your allowance but the cost of that extra bandwidth may be less than the cost of subscribing to watching the same football match or the cost of online renting of the film. NTL could make a range of events and films available online through something like broadband plus that you pay for in "over the cap" charges rather than not getting any profit out of third party online video rentals that would be the case if they had a much larger cap.

Read the news article on the front page.

My take on it, (i'm sure i'll be corrected if wrong) by the end of 06 all will be on 10M, but each will have different levels or caps, you can buy higher bandwidths has you need it, i think.

Millay · 08-08-2005, 13:16

hmmm, do we have to have this thread now for another two/three how ever long months

...

Surly those of us on 3mbit are surfeing at pretty much flat out for web pages, they cant appear much quicker.. my 1 - 3mbit uprgrade was great, but this whilst I welcome it and look forward to using it for mutimedia etc... I can wait it will happen, it will be great when it does... just be cool

Chrysalis · 08-08-2005, 13:16

Really am looking forward to this, I wonder if telewest top dogs had say in this as to ensure NTL have products to please telewest customers when merger happens.

I would expect a mass of people upgrading to top tier when the news hits of first batch of 3mbit getting the upgrades, and is there any indication that the 75 gig is still a soft cap or will be a hard cap? I am hoping it stays as a guideline that NTL only enforce when congestion occurs.
