Any plans to increase speed

When I was on the digital region network they updated the profiles to allow speeds of around 90meg+ , are there any plans to do this on the BT network?

The only issue I can see is that digital region had to replace some line cards at the CAB as the current ones only supported 70-80meg.

The 'only' problem? Id' say that if it applied to BT's network it'd be a pretty major, if not devastating issue.

It would seem likely that BT would want their FTTC network to be able to hit the EU Digital Agenda targets for 2020; the obvious change necessary would be packages for 100Mbps.

They could probably choose to do that now, but not many people would be able to get those speeds - the main restriction now coming from crosstalk, caused by high takeup.

It would seem likely that higher speed packages will only come about when those problem are countered - by the use of vectoring. That too seems likely to require new hardware, so might also be limited.

Vectoring alone might not be enough either; DLM might need to make use of alternatives to FEC & interleaving, such as G.INP and SRA. Tools such as these might counter the 10% reduction in speed triggered by today's DLM.

If you are feeling reasonably flush then FTTP is your best chance of higher speeds with BT.

Requires profile 30 which makes vectoring and or g.fast harder so no.

Faster options might appear via vectoring

that may be part of the reason to ditch the supplied modems, as I would guess many of the 3rd party devices are gigabit capable, the billion 8800nl i am using now I consider a budget device but it still has a gigabit ethernet port. It has a good stable broadcom DSL chipset as well.

If you're talking FTTPoD then it isn't available everywhere (in fact I think the footprint is still quite small at the moment). Plus FTTPoD is pretty much business only and carries a 36 month contract tie in and the only option is the top 330Mb/s package.

FTTP itself isn't available where FTTC is delivered.

They could increase the headline speed to 100Mb though I don't think they'd be able to achieve the 10% of people connecting at 100Mb without spending some money on vectoring.

Certainly there's nothing stopping them doing it though, the line cards in BT's current kit are the same standard as those Digital Region were using.

no chance. 80/20 is to stay with us for the next 3 years until 2018 then BT only uplift to 100Mb from 80Mb.

BT is far behind than rest of superfast fibre!

adsl max -- think you might not be correct there --

Is there a way to put ADSLmax on ignore on these forums?

Given the Superfast Cymru contract requires BT to produce 100Mb next year I'm going to take a wild guess that you're wrong.

Surprised one of your numerous extremely high level contacts within BT couldn't fill you in.

Won't be an 'uplift' either - separate new product. Openreach can't simply increase speeds as Virgin Media do.

Cheeky sod!

Most (If not all) of the Line Cards installed on Openreach cabinets are Profile 17a which are (Per specification) capable of Up to 100Mbps downstream.

A Cisco document I looked at a few days ago for a VDSL2 WAN Interface mentioned a combined data rate of 17a to be 150Mbps; which I'm assuming is 100Mbps down and 50Mbps up.

So I'm guessing BTw could raise it to that if they wanted too, but I'd like to think they are looking more into Vectoring first...

those speeds realistically need vectoring to be marketable.

I think post vectoring we will either see 100 or 120mbit services. I would be surprised if was no change, as BT will want something back for their investment, no matter how small it is.

Personally I would be happy with 80mbit alongside a decent snrm which would be the case if vectoring was enabled for me, I dont see a jump from 80 to 100 been significant.

surprised then why they don't release a max package to allow people to connect at whatever there currently syncing at. On my router its showing a max rate of 98 meg so if the line cards are capable why not just alter the profile to let people make use of whats there.

My guess would be that they aren't offering a max service at the moment (while vectoring's not implemented at least) because it would likely increase crosstalk (more bitloading used up on all 'max' lines, and as such I imagine the power output would be around 13.0dBm or higher on the downstream - again for crosstalk). When vectoring is rolled out, perhaps in the future such service might be offered.

As I understand it, vectoring capable hardware is being rolled out into DSLAM's at the moment, so at some point in 2015 we might well see vectoring or at least an official announcement from Openreach prior to the activation of vectoring.
