Re: 200Mbit coming soon? (According to a survey)
 

Most cabinets should be able to accommodate them but no doubt there will be many that need replacing.

The £5500(approx) is for: Shelf, 4 Line cards, COGE3 Card, lomi8 card, fans and cabling. This is for a straight swap of existing shelf. Then the STM1 Transmission shelf will then be replaced with ECI Broadgate in the cabinet and headend so another £3-4000,(approx). The you need extra pair of fibres for the comm's to the MSAN shelf again massive cost and waste of fibre in my opinion. This is a very basic costing as around the country there are different vendors in use, Nortel,Nokia,Marconi ect all with there differing requirements.

The cabling from Line cards to E sides again brings many problems and solutions have been tried but you can't beat ripping out the existing interface cabling and replacing with new from Line card to E side but again this is a massive cost in labour for contractors

Re: 200Mbit coming soon? (According to a survey)
 

I can only go off the documentation I have seen, I'm not in the Access dept so not close to it.

But from what I have seen last year, DOCSIS 3.1 deployment is scheduled to start in Q2 next year, with a further upgrade planned in Q3 2017. The network is planned to be 600Mb ready by end 2016/2017.

There's a whole host of other stuff to be looked at as well CCAP, EPoC running DOCSIS 3.0 and 3.1 together and other stuff that is outside of my area of expertise

OF course 10Gb is not going to be offered, why would it. It's theoretical. The main thrust of the article is that VM is moving to Docisis 3.1. and from what I've seen it will be well before 2020 - I don't know where you get that from.

Re: 200Mbit coming soon? (According to a survey)
 

Yeah, isn't the "theoretical" of DOCSIS 3.0 something like 1.5Gbit?

Re: 200Mbit coming soon? (According to a survey)
 

I agree, at some point last year one of the forum users posted a powerpoint presentation which Neil Burkett (sp) used at the AGM and it in they discussed VM's plans for docsis3.1 and their deployment strategy. They definitely said they were going to being domestic trials this year with a view to it being rolled out next year.

Re: 200Mbit coming soon? (According to a survey)
 

So nowhere near 10Gb then.
Which is what I've been saying all along

Did you miss the title or the start of the article? Or the particular sentence I was specifically quoting from?


---------- Post added at 18:48 ---------- Previous post was at 18:46 ----------

That's about as likely as 10Gb on D3.1.

If they ever go 10Gb it'll involve such a big rebuild they may as well go FTTB or FTTP.

Re: 200Mbit coming soon? (According to a survey)
 

yeah that's pretty much my point, if D3 is capable of 1.5Gbit and we're sitting on 150Mbit (maybe 300 or even 600 in some years), then all the hoohah about D3.1's theoretical speeds is worth nothing.

Re: 200Mbit coming soon? (According to a survey)
 

I think there's some confusion here.

Pierre wasn't saying that VM will deliver 10Gb via DOCSIS 3.1 this year or next. He was I believe saying that VM will be delivering 300Mb via DOCSIS 3, which they will, and that they are working towards 3.1, which they are.

The network is certainly going to have work done on it, however this work will not be anywhere near as extensive as an FTTP overlay, it will be closer in cost per premises passed to BT's FTTC build as it will entail conversion to an FTTLA HFC architecture.

Shorter term the main plan will be upgrading the network so that return is split at 85MHz or higher and downstream is at 1GHz which along with further resegmentation will push fibre deeper into the access network anyway. Between those, CMTS, and CPE upgrades delivering 1Gb/100Mb via HFC using nothing more than DOCSIS 3 becomes a possibility.

DOCSIS 3.1-capable kit is there right now with more being deployed.

I would think they will as they know BT have trialled G.FAST and have opened a lab at Adastral Park to develop it further.

Re: 200Mbit coming soon? (According to a survey)
 

I doubt they'll be too scared of a product in production exactly nowhere with no finished final hardware and not on BT's roadmap for commercial deployment.

BT Labs are pretty busy with lots of new tech, such as VDSL and PON, still a way behind in deploying them commercially.

Re: 200Mbit coming soon? (According to a survey)
 

They haven't even managed vectoring yet , things continue to move at a glacial pace.

Re: 200Mbit coming soon? (According to a survey)
 

Openreach and BT generally have never had any interest in competing with Virgin on speed and this isn't going to change.

Vectoring will happen as and when BT need it to in order to adhere to the Superfast Cymru contract and any others that name 100Mb as a requirement.

Re: 200Mbit coming soon? (According to a survey)
 

Sorry. I was specifically referring to the first sentence that said "could eventually... 10Gb" so I assumed the response was directed at that.

Re: 200Mbit coming soon? (According to a survey)
 

I would expect the roll out of vectoring to start in Q3 this year.

Re: 200Mbit coming soon? (According to a survey)
 

I also like how 802.11n has now been inflated up to 1Gb/s in the 2.4Ghz band.

Re: 200Mbit coming soon? (According to a survey)
 

The ratios are way better this time around :)

392MHz of spectrum for downloads, 192MHz for uploads.

Currently on US cable networks it's more like 35MHz for uploads, not all of which is usable that's closer to 27MHz, and over 900MHz for download, of which modern CPE can use 192MHz.

Sightly better on Euro networks but even on the best of those the ratio is 60MHz, of which perhaps 45MHz is usable, to 256MHz via modern 32 channel CPE out of, again, over 900MHz.

Fully DOCSIS 3.1-ready networks have been in planning for a while as it's always been expected that at some point customers would be wanting much higher upstream speeds.

No reason why VM's plant can't be mid-split before my 40th birthday.

Re: 200Mbit coming soon? (According to a survey)
 

Well, that's the hardware capabilities of the CPE, but as you say the network itself has to be physically wired to support it... and that's not a small task.

The maximum hardware capabilities haven't ever been particularly relevant to the actual marketed end-user speeds. After all, previous (DOCSIS 1.0, DOCSIS 2.0, and debatably the VMNG300 D3.0) hardware have all been capable of much better ratios than current CPEs that actual products never came close to offering.


And if a highly capable D3.1 CPE were to be deployed on the current networks within the next year or so, it would actually make it worse, not better, since the CPE would allow more downstream to be utilised yet the upstream spectrum would still be limited by the physical network.

Re: 200Mbit coming soon? (According to a survey)
 

3.1 can offer an immediate improvement in upstream speeds over the current set up even without physical network changes. 3.1 also needs work on the downstream; there's a fair amount of linear TV and VOD there and finding the equivalent of another 33 free QAMs of downstream spectrum over the current band plan isn't trivial.

Regardless the CPE and standards support a far better practical upstream ratio than the predecessors.

It's also worth mentioning that the ratios deployed elsewhere in the world are quite different from those here which have historically been conservative on the upstream.

The USA come to mind as some who pushed upstream hard in the past. A 101/35 tier from Cablevision on DOCSIS 3.0 and 30/5 on US DOCSIS 2.0 come to mind.

VM and the rest of the Liberty Global group will be upgrading networks accordingly in any event.

It's a non-issue though as VM aren't going to be deploying a DOCSIS 3.1 product imminently, there's plenty of life left in DOCSIS 3.0.

Re: 200Mbit coming soon? (According to a survey)
 

Yes it will, but it won't magically open up 192Mhz of upstream capacity without the network split being physically changed, while the 392Mhz of downstream capability can be used pretty much straight away.

Only the current generation of 8 down 4 up D3 CPEs. Wasn't the VMNG300 theoretically 4 down 4 up, and DOCSIS 2 and before were all 1 down 1 up anyway.

Didn't we establish VM were going to start deploying D3.1 early next year?

Re: 200Mbit coming soon? (According to a survey)
 

Wasn't the theoretical 8/8 with a firmware update?

Re: 200Mbit coming soon? (According to a survey)
 

no, it was 8/4 and VM ran out of contract with the manufacturer so they couldn't get the new firmware made. The vmng300 would have been a cracking modem if it could load balance across 8 channels.

Re: 200Mbit coming soon? (According to a survey)
 

Between me and everyone else to ever visit this site. 400mb d/l will be the next big step ;) and uploads will be increased by a huge amount :)

Re: 200Mbit coming soon? (According to a survey)
 

You think cable companies have that much unused downstream capacity lying around ready to be used pretty much straight away?

Finding another 64MHz for this year's upgrades was a non-trivial task. Some areas are going to need, and will receive, plant upgrade to go further. Part of this upgrade is 85MHz mid-range upstream with a relatively easy upgrade to full DOCSIS 3.1 range via diplexer swap.

If dealing with VM:

I mentioned specifically practical ratio and chose my words carefully on that one. EuroDOCSIS 1/1.1 you were dealing with 50Mb downstream, 10.24Mb upstream channels, usually at a ratio of 1:4 or 1:3 making offering anything like symmetry extremely unwise as channels degraded at c.70% utilisation and upstream usage was way more constant than downstream.

EuroDOCSIS 2.0 is a different animal but still maximum upstream bandwidth 27Mb with same restrictions on channel degradation hence perhaps 20Mb usable at most. The highest service tier I've seen on DOCSIS 2 was 10Mb.

Statistical contention has left more options and this effect on 3.1 will be even more pronounced.

Did we? Liberty Global doesn't mean VM by default. This tech is more likely to be deployed where a Liberty Global company is in competition with FTTP or where a hardware refresh is due.

The plans for the next couple of years at least are focused around DOCSIS 3.0. Subject to change of course.

VM are deploying new kit, some of which is DOCSIS 3.1 ready, however 3.0 supplies what is needed for a while. It's not like Openreach are pushing hard with their 80Mb/20Mb FTTC product - VM will be offering the same or better than anything Openreach offer in consumer grade services anywhere in their footprint by the end of the year.

---------- Post added at 23:16 ---------- Previous post was at 23:15 ----------

No, quite the opposite. The fact that it will be restricted to the current spectrum until major network upgrades are done means it will not offer a huge change in available ratios.

Re: 200Mbit coming soon? (According to a survey)
 

Exactamundo. We've had some pretty authoritative information from those who do know.

Re: 200Mbit coming soon? (According to a survey)
 

Can't really say much about this part as probably TMI, beyond that I suspect Pierre was referring to DOCSIS 3.1-ready equipment along with 'other' upgrades. The plans as they stand are for deployment of more DOCSIS 3.0 downstreams and this has kicked off already, with 600Mb-ready network coming via more of the same.

That ignores a number of issues preventing more efficient use of the current spectrum. VM's upstream ratios are not due to a lack of upstream split.

As far as VM go though it's not really an issue. There won't be a DOCSIS 3.1 transition for a while yet. Kit is going in that is ready for it but plans still focus around DOCSIS 3.0, not to mention that major network upgrades start soon per comments in the thread about massive network upgrades :)

---------- Post added at 09:41 ---------- Previous post was at 09:39 ----------

A guy making a first post on the forum predicting a near-tripling of VM's speeds downstream and huge increases upstream?

Clearly legit.

VM have no need to go ridiculous, they're already #1 in 95% of their covered areas.

Re: 200Mbit coming soon? (According to a survey)
 

Or it could be a very knowledgable existing member registering a new alias so that the 'leak' couldn't be traced to him ;)

They were already #1 in most of their covered areas before they decided to 'go ridiculous' and double BT's headline speed. Clearly 152 was a direct shot at BT/FTTC, so who knows, VM 400 may be a shot at BT's last remaining stronghold, 330Mbps FTTP.

Re: 200Mbit coming soon? (According to a survey)
 

100Mb -> 120Mb -> 152Mb was relatively easy. 300Mb / 400Mb not so much.

I'd best pass this on to the guys planning the additional capacity for this year's upgrades with the note that they need to find another ~33%. :)

Re: 200Mbit coming soon? (According to a survey)
 

True, but either way they were already well ahead with 100/120 in most areas (as long as you didn't take peak-time congestion into account). Beyond 'pwning BT' there wasn't really any other reason to come up with 152 was there?

Hehe. You and I both know that higher maximum speeds don't result in a proportional increase in utilisation so the actual required capacity will be less than the increase in headline speed. ;)

Re: 200Mbit coming soon? (According to a survey)
 

I'll restate. I'm privy to some capacity planning information and it's not being done on the basis of 400Mb with a 'huge' upstream increase for right now.

Re: 200Mbit coming soon? (According to a survey)
 

As it's most likely confidential we won't ask either.;)

Re: 200Mbit coming soon? (According to a survey)
 

It's not just about keeping up with VM , the BT Ceo claims to be interested in making a big push on their TV product.

To qualify for a multi room box you need BB speeds of at least 23 Mbps which in my opinion isn't enough if you have two recordable HD boxes. Recording or watching one Internet HD channel uses around 8 Mbps with two tuners per box that can soon push some upto their maximum infinity connection.

BT have also discussed their aspirations to introduce 4K Sport which would require considerably more , Netflix 4K currently requires a connection of 15 Mbps or greater so you'd imagine fast moving sport would be at least 20.

Re: 200Mbit coming soon? (According to a survey)
 

BT will be delivering about 40Mb to about 50% of the population. I suspect they're fine with that for a while.

To deliver too much more will start to cost some serious money. BT aren't huge fans of spending money on infrastructure, they prefer spending on content these days.

Re: 200Mbit coming soon? (According to a survey)
 

Considering 1080p Blu-ray averages over 30Mbps (taking the example of the LOTR trilogy) decent quality 4K is going to require considerably more than 15-20Mbps.

Re: 200Mbit coming soon? (According to a survey)
 

But then your comparing optical media to broadcast/streaming , Netflix streams 4K using the HEVC/H.265 codec and recommends a connection of 25 Mbps although the stream requires around 15 Mbps the results are pretty good in my experience.

Re: 200Mbit coming soon? (According to a survey)
 

That's the whole point. Streaming quality is crap. Streaming services are held to pathetically poor standards because everyone is used to sub-720p quality being labelled '1080p' and proper 1080p quality being labelled 4K.

The results are pathetically poor in my experience.

Re: 200Mbit coming soon? (According to a survey)
 

So this years upgrade is ~225Mbps? as 33% on top of that is 300Mbps ;)

Re: 200Mbit coming soon? (According to a survey)
 

This year's top tier will be 300 :)

Re: 200Mbit coming soon? (According to a survey)
 

Heh, I forgot about the audio. Blu-ray disks with DTS-HD Master audio (which are widely available today) can use up to 25Mbit/s just for the audio alone. Never mind what upcoming Dolby Atmos audio tracks will use, with up to 128 audio streams...

---------- Post added at 00:42 ---------- Previous post was at 00:41 ----------

I'd offer, but without a Blu-Ray drive in my PC all I can do is take poor quality phone-cam shots of my projector screen while playing it... kinda defeats the point. Also lack of frame control that way.

Re: 200Mbit coming soon? (According to a survey)
 

In the case of the Lord of the Rings trilogy the following bit rates were used for the extended edition Blu Rays:

LOTR: Fellowship of the Ring
Average video: 29.84Mbps
Average audio: 4.717Mbps

LOTR: The Two Towers
Average video: 29.9Mbps
Average audio: 4.427Mbps

LOTR: The Return of the King
Average video: 30.23Mbps
Average audio: 4.474Mbps

The comparisons I linked were notable in mentioning the difference in audio quality.

Fingers crossed that, at some point fairly soon, enhanced lossy codecs and lower bit rates aren't needed to compensate for sub-standard networks.

Re: 200Mbit coming soon? (According to a survey)
 

Yeah, I wasn't trying to dispute the streaming vs Blu-ray argument at all, I was genuinely curious to see how things like streamed h.265 stacks up against say an MPEG-2 blu-ray. It's one thing to mention bit rates but if the CODEC is naff, then it's not the full picture.

Re: 200Mbit coming soon? (According to a survey)
 

I'm puzzled how we got onto Blu Ray from talking about broadcasting/streaming sport.

Shock horror Blu Ray offers greater PQ and specs.

Re: 200Mbit coming soon? (According to a survey)
 

Indeed, that's what reminded me of it in the first place. The LOTR trilogy is faily old by now, but does still use DTS-HD Master audio, although only in 6.1 format. Regardless, up to 25Mbit/s peaks are allowed, even if the average is much lower.

That, in fact, leads me to one of the fundamental differences between streaming and optical media - the latter allows for much higher variability in data rate, whereas streaming is more akin to the CBR (constant bit-rate) encoding that was used in the very early days that has been long since abandoned, because, well, it sucked.

Unfortunately for decent VBR steams to work we either need much faster (peak) internet connections or bigger buffers... And nobody likes buffering.

---------- Post added at 11:46 ---------- Previous post was at 11:43 ----------

Well, H.265 streaming is just as rare as MPEG-2 Blu-Ray, as in both are the exception to the norm. Most streaming uses H.264 class codecs as do most Blu-rays. It's only very old Blu-rays and very new streamers that do different, so comparing a 2016 codec to a 2006 codec isn't exactly representative :p:

Speaking of, H.265, 4K, wide-gamut and deep-colour have all been incorporated into the Blu-ray UHD standard now, so streaming is going to have even more competition.

---------- Post added at 11:56 ---------- Previous post was at 11:46 ----------

Actually, now that you mention it, that's missing out one very important metric: bits per pixel. Those movies frames are 1920x800x24p equating to 36.9 million pixels per second, represented by around 30 million bits per second of data.

HDTV broadcasts and/or streams are typically 1920x1080x30p or 60p equating to at least 62.2 million pixels per second, or in other words, that's at a minimum already 70% more data that has to be compressed into one third the bitrate.

Speaking of, Sony's 'Mastered in 4K' blurays are 1080p media with an enhanced average bitrate of 35Mbps to 38Mbps supposedly.

Re: 200Mbit coming soon? (According to a survey)
 

H.265 is already in use , Netflix use it for 4K , Wuaki are using it for 4K Amazon Instant 4K some Youtube 4K uses it as well as Google's own VP9.

Re: 200Mbit coming soon? (According to a survey)
 

And none of them are 1080p

Re: 200Mbit coming soon? (According to a survey)
 

Agreed but that's hardly surprising considering many who can already watch 1080p streaming would be ruled out as they'd need new hardware.

Re: 200Mbit coming soon? (According to a survey)
 

Yes they would, although ruling out PCs which are perfectly capable of software decoding is a bit obtuse.

Regardless, the point was Kushan was interested in a comparison between streaming and Blu-ray quality, presumably at the same resolution - in which case the same codec is likely to be used for both.

Re: 200Mbit coming soon? (According to a survey)
 

All this talk of higher speeds - I'm still hoping VM Business get their issues with static IP on the 152 Mb/s service fixed quickly, otherwise the 50 Mb/s service could look decidedly slow in the range of services they offer :-)

As it is, when compared to new residential services it's bottom tier now and could be below bottom tier soon!

Re: 200Mbit coming soon? (According to a survey)
 

In this thread, peops seem focused on the speeds. Well it called 200 meg coming soon.

100/200/300 has been put forward as the VM end point for DOCSIS 3.0 (was it me?) with an interim of 50/150/200 or something like that.

Then there has been talk of 12 or 16 downstreams and capability for 24 downstream channels.

Has anybody thought about what's going on in the real world? Line cards on BSR? Are Motorola BSRs now end of life and being replaced by Arris? Do the hubs/data centres have the electrical power and server room space for build and transition? Will they have to temporarily put 12 channel line cards into BSRs at crowded local hubs while they sort out their space issues?

These are the real behind the scenes challenges for VM to be able to wave their willy even higher.

Not to mention that are still DOCSIS areas out there (not many) but area upgrades have to happen everywhere. That would include FTTP using RFOG which can happen in any area getting a complete overhaul because of 20 year old cab amps. There's stacks of behind the scenes stuff they play real close to their chest to make all this happen.

Re: 200Mbit coming soon? (According to a survey)
 

Just spoke to a virgin bloke in one of the green cabs around here, he said there will defiantly be an increase this year, he said the packages are likely to be 300mb top tier then 200 and 100.

In every upgrade programme there will always be those upgraded early and those upgraded near the end. I speak from experience having been right near the end for the upstream 10:1 upgrades way back when as my area needed rebuilding. Not a bad thing to be near the end either, probably means lots of network upgrades are coming.

I don't care about downstream any more i just want a decent upstream for streaming. Does any one have an idea as to what the upload would be on 300mb and 200mb ?

Somewhere vaguely in the region of between 10:1 and 20:1

Re: 200Mbit coming soon? (According to a survey)
 

But then, they did introduce 152 just to one-up BT, so for the same reason I'd think 24 up is more likely than 20 - again just to beat BT.

Re: 200Mbit coming soon? (According to a survey)
 

true

Re: 200Mbit coming soon? (According to a survey)
 

anything over 20mb upload sounds good to me

Re: 200Mbit coming soon? (According to a survey)
 

absolutely, the only reason why I wanted 100mbits, 120 and 152 was for the upload speed. I was very lucky that in that I signed up for the initial 100mbit tier as soon as it became available and got put on 100/10 a few months before they stopped it so I have been on 10mbits+ for 2 and a half years now I think.

Re: 200Mbit coming soon? (According to a survey)
 

24 isn't on the table. 20 is fine to beat BT.

Re: 200Mbit coming soon? (According to a survey)
 

Given that VM historically don't overprovision on the upstream, and to date there's no mention of STM going away on the upstream, it will at best equal BT not beat them...

Re: 200Mbit coming soon? (According to a survey)
 

The 'current' 152/12, 100/6 and 50/3 tiers are all overprovisioned 5% on upstream to comply with ASA regulations.

The 152/12 is overprovisioned to 12.6 Mb, the 100/6 is 6.32 Mb, the 50/3 3.17Mb.

Well some areas are already on QAM64 for the upstream. I wouldn't be surprised if more channels started appearing, too.

Re: 200Mbit coming soon? (According to a survey)
 

Will all areas go to 64QAM? I ask as being in an area fed from New Malden. Upstream here has historically been poor due to the state of the network. Hopefully the work to rectify that has left in in good shape for this.

Re: 200Mbit coming soon? (According to a survey)

By the year 2017 BT FTTC will be 400/40! :):D

Welcome back telfordcable.

VM will (to my mind obviously) programme things so that every area is up to the same standard. Indeed if it's to have 100/200/300 tiers, then the two higher tiers will need the 64QAM and additional channels. Whether > 2 channels will be provisioned to the 100 meg tier, I can't say.

I thought he was permanently banned at the same time that nuttehbutteh dude was.

Re: 200Mbit coming soon? (According to a survey)
 

Every tier will be provisioned the same so all DOCSIS 3 devices regardless of their service tier will receive as many upstream channels as are available in the group. :)

Modems that only have 8x4 cable front ends in areas with >8 channels will lock to the 8 channels they are offered, while 24x8 or 32x8 modems will take the whole group. This is done on a per-CPE basis to load balance channels - note that in the case of those in areas with 12 downstreams already some top out at 291MHz and go right down to 235MHz while others are on the same channels they were when the area was running on 8, 267MHz - 323MHz, and yet others run on 251MHz - 307MHz.

Load balanced across in 3 groups of channels 1-8, 3-10 and 5-12. Channels have to run consecutively so this is the best they can do.

Just to clarify BT's FTTC will not be 400Mb/40Mb by 2017. The current FTTC product might be in the 100Mb/30Mb ballpark but cannot go to 400Mb.

This will be a new product using the new standard G.fast. BT have not announced any details of the download or upload speeds they plan to offer on the newer standard they'll be rolling out, beyond that they plan on offering 500Mb to 'most' homes by 2025 and will start in 2016-17, with the hope of offering 'a few hundred' megabits per second to 'millions' of homes and businesses by 2020.

Things will be clearer when they have done the trials. As this is brand new technology BT do not know what it's capable of when rolled out to any kind of scale - no-one does yet as it hasn't been rolled out to any kind of scale yet, so it won't surprise anyone to know that 400Mb/40Mb was a number picked out of the hindmost and, regardless, the upload speed will be way higher than 10% of download in any event.

VM will be at gigabit speeds, if necessary to compete, by 2020.

you obviously don't know what you are talking about because our No 1 most reliable source of information on this forum says otherwise

Re: 200Mbit coming soon? (According to a survey)
 

I wont believe it until I hear truthspeaker speak it.

Re: 200Mbit coming soon? (According to a survey)
 

No chance of that! :rolleyes:

BT can get up to 500Mbps to 1000Mbps download /250Mbps to 500Mbps upload with G.fast and super vectoring

:p::D Many thanks. The evil telford cable are back!

Re: 200Mbit coming soon? (According to a survey)
 

Interesting. The fastest they've managed with the trials so far is 786Mb download, 231Mb upload, at 19m, with no vectoring needed as that was the only G.fast signal on the cable bundle.

Evidently you're privvy to some information that the people doing the trials themselves aren't.

As well as that you also seem to know more about Virgin Media's plans for future capacity upgrades than Virgin Media do.

All in all I'm thinking we need to ask you what the lottery numbers are as you appear to have a crystal ball.

Re: 200Mbit coming soon? (According to a survey)
 

I doubt Virgin Media will NOT roll out nationwide Fibre To The House! Like London already have it with VM.

Re: 200Mbit coming soon? (According to a survey)
 

There's nowhere in London with FTTP from Virgin Media. The trials are at Papworth and Edinburgh.

There are no plans to upgrade existing areas to FTTP in the near term. The coaxial network can, with upgrades, deliver very high speeds.

Next please.

Were they not the same person ?

Re: 200Mbit coming soon? (According to a survey)
 

Re: 200Mbit coming soon? (According to a survey)
 

Yeah but like he said, that's without super vectoring.

---------- Post added at 20:32 ---------- Previous post was at 20:32 ----------

What? Where?

---------- Post added at 20:33 ---------- Previous post was at 20:32 ----------

It's super faster than normal vectoring.

Re: 200Mbit coming soon? (According to a survey)
 

BT are keeping it a secret! Super Vectoring will be a winner! Virgin Media will going lose the best fastest uk broadband in UK soon.

Unless you can back up your assertions with appropriate links/quotes, kindly stop posting crap.

Re: 200Mbit coming soon? (According to a survey)
 

Not much of a secret really given you got it from ISPReview.

Doesn't exist even in a lab. VM's plans call for the capability to deliver higher downstream than that tech is 'theorised' to by 2016, with the upgrade path to do it mapped out and the budget in place.

Re: 200Mbit coming soon? (According to a survey)
 

I would have just said "stop posting crap"

So why do i now have this config, was a 100Mbps connection (speed doubled from the 50 I was paying for? http://www.cableforum.co.uk/board/35738962-post130.html)

Super Hub VMDG480 config now


Wooosh!
Only speedTests at 170Mb/s max mind, and I probably need a new router (Asus N66), but clearly way over the 108 it used to be!
