DOCSIS 3.0 across the pond

Tipped by Ignite See Profile
One of our resident UK readers sends word that the CEO of UK's biggest cable company (NTL) has announced a 50Mbit product to be commercially trialled by paying customers. According to this earnings report (pdf), the speedy tier should arrive sometime this month. The product is "wideband DOCSIS, possibly with the modem in the cabinet then ethernet over coax from there, due to the high cost of the wideband DOCSIS kit," tips the user.

Their current internet plans are:
»www.home.ntl.com/icat/broadband

Their terms are here:
»www.home.ntl.com/page/broadbandusage
and here:
There are no monthly caps on internet usage. See section 20.2 of this link for info about no monthly caps being applied. »www.home.ntl.com/page/userpolicy

P.S. They are changing name from NTL to Virgin Media in 1st qtr 2007:

Re: American ISP's are you listening..

If you look at there terms look at the bottom. Monthly Usage Allowance. but there is a number 4. im guessing dail-up? "These services are provided through a BT line and not through the ntl cable network"

It isn't dial-up. But it is like a CLEC in the US. Some NTL broadband is offered over BT circuits, where the BT rules apply.

coax Ethernet from the node??????

If your running ethernet over coax for the last mile, why dont they deploy ethernet over coax from a fiber node for the last mile, much higher speeds, less overhead, less D2A, A2A, A2C conversions. The DOCSIS 3 to Coax Ethernet convertor isnt going to be a cheap piece of equipment (its active electronics), and it eats line power, why dont they just do Coax Ethernet to the home stright from the nice fat fiber node?

Presumably because that would involve a cabling infrastructure upgrade too. A typical HFC network consists of a node that drives a hundred or more drops via a series of amplifiers and multi-port taps. I guess that what NTL are planning to do is place a multi-user DOCSIS 3 modem in each tap (which from what I remember have many more ports than the typical tap used in the US), meaning that each user then has a dedicated coax link from the modem to their house. With your plan, multiple Ethernet-over-coax links would need to be carried from the node to the taps, and this may be beyond the capabilities of the existing coax.

Isnt the speed increase nullified by sharing a individual modem?

I suspect that the "device" is actually a multiple-modem unit. In other words, it offers the same functionality as multiple individual modems but in one physical device, allowing the sharing of some circuitry such as the node-side interface, power supply, control function etc. This sharing would ensure that an N-port modem was considerably cheaper than 'N' discrete modems.

Range and the requirement to add additional equipment to every cabinet on the path from node to customer doing it that way.

Check the Narad Networks products, you'll note that to get the signal through a standard CATV amp it needs to be split off before the CATV amp then recombined with the output of the CATV amp it as it has to work at different frequencies which are outside the range of the CATV amps, which usually tend to max on most plants at 880MHz or less.

Unlikely for there to be room there for the ethernet signal, but enough room for 4 6/8MHz wide QAM carriers, yep, sure.

England - useless broadband through capping!

Isn't the UK the country where you can have a 10 mbps downstream with a 60 GB/month cap?

I'd take my old 3/768 DSL from verizon over an UK ISP anyday. But I'd rather keep the 31/9.5 I have now without caps.

If you're "stuck" with comcast and their 3-6(I don't keep up with cable speeds), or roadrunner's 4-10 mbps connections, don't feel bad. At least you can use it.

Re: England - useless broadband through capping!

Sorry we've no ISPs offering 10Mbit with a 60GB/month limit.

Infact I'm not aware of any service of >8Mbit with a cap unless you choose to pay less for a capped service, about half the country is covered by uncapped ADSL2+, and a similar amount by uncapped cable.

Yep half the country has access to up to 24Mbit services, I think that's a tad higher than the proportion covered by FIOS, which is to be honest the only thing I envy about the US HSI market.

Perhaps do your research before making sweeping statements though sir

I did. Just because BT or NTL are not capping at this minute does not mean they haven't capped on and off in the past, or that they won't do so in the near future.

Here's the last article I read. Before you say "ZOMG THAT'S OLD", I don't have much reason to keep up with british broadband.

»news.bbc.co.uk/1/hi/technology/4749987.stm

quote:
Cable firm NTL is to up the basic speeds of its broadband offering to 10Mbps.
quote:
NTL also said that usage allowances would go up from 30GB to 75GB a month.
The caps come then are revoked, then come then are revoked. If they ramp the speed up by 2-5x in the future, do you think there really won't be any capping done?

Re: England - useless broadband through capping!

Yep, we're a tad more competitive now than we were, check the LLU story for evidence of this.

Should also mention that ntl never, ever actually enforced the caps that were placed on the service. They were politely informed by the public that capping wasn't seen as acceptable, and despite leaving the caps in the T+Cs never pulled up anyone for going over those limits.

A quick google search doesn't really count as research sir

The UK market now doesn't really do capping apart from on cheaper products or those which have to use the ILEC's wholesale services. Shaping tends to be more used where needed.

The largest pay TV company in the UK offering uncapped ADSL2+ for less than $20 a month on top of a TV package costing as little as $30, with a rollout plan covering 70% of the population.

Companies like Bethere offering uncapped ADSL2+ up to 24Mbit for $45/month, coverage soon to be about the same as cable.

Bulldog currently offering uncapped ADSL2+ and telco line rental for less than $60/month.

UKOnline offers uncapped ADSL2+ for less than $60/month.

You can see why capping isn't the most popular thing, too many options that aren't capped.

I am quite amused by the way that you mentioned Comcast as an example of good old uncapped USA broadband. Probably not the best move to discuss an ISP with a history of capping its' users but not actually telling them what those limits were.

quote:
According to a spokeswoman, the company began sending notes about two months ago to the top 1 percent of the heaviest users--people who collectively use about 28 percent of the company's bandwidth--telling them they were violating their terms of service.
To quote you:

FIOS is your shining light among a group ranging largely from mediocrity to poor service. A couple of odd exceptions such as OOL but largely average at best, piss poor at worst.

How much of the US has this amount of options?

BT Wholesale ADSL Max - Up to 8Mbit RADSL, ILEC DSLAM, choose from over 200 ISPs using wholesale product, wide variety of capped and uncapped prices and speeds.
BT Wholesale SDSL - Up to 2Mbit SHDSL, ILEC DSLAM, choice of several wholesale product users, prices.
Be LLU - Up to 24Mbit uncapped ADSL2+
Bulldog LLU - Up to 24Mbit uncapped ADSL2+
Easynet LLU (aka Sky Broadband) - Up to 24Mbit uncapped ADSL2+ and bonded SDSL up to 4Mbit
Homechoice LLU - Up to 8Mbit uncapped ADSL + IPTV / VOD
Pipex LLU - Up to 8Mbit ADSL / VoIP
Tiscali LLU - No comment as these guys suck
NTL Cable - Speaks for itself

Re: England - useless broadband through capping!

I have dissed comcast and roadrunner many times both on this forum and in the DSLR IRC channel. Comcast would put a random cap around 30 GB/month uploaded, but they never cared how much you downloaded. This is pretty lame but it is better than a cap both ways, IMO.

I do not have that many options here. I can get covad resellers for 768/128 for $50/month with a one year contract. Roadrunner cable, I believe 4/384 here for $40-$45/month, verizon DSL 3/768 for $30/month, or FIOS 31/9.5 for $55/month. There are choices here too - it's pretty obvious which is best, but it's not like all of america has one ISP per area.
