Interesting that they'll upgrade people to 80 mb/s when its available (If i read that correctly) although with it being a DSL variant isp its much more "up to" then cable where you get nearly exactly the speed you pay

I'm getting 40/10 sync but actual speeds of 37/8 on each of my two FTTC connections. The last engineer to visit told me that just 5 of the slots in the fibre cabinet serving me have been used so far, out of a potential 95 or 98 (forgotten which). I haven't seen any offerings by ISPs based on the 15Mbit upload speed product that OpenReach are discontinuing. There's a Google Docs spreadsheet detailing many FTTC offerings of the OpenReach products at: http://bit.ly/f3il0d

It's not much more "up to" at all, only a little. The vast majority (70%) of people on 40mbps VDSL have sync speeds of 38mbps or higher, 80% get at least 35mbps, and only 10% get 30mbps or less.

Not sure if the 80mbps will be using a fatter profile (at which point it will be more variable) or bonded lines (at which point it won't, and 70%+ of people will get 76mbps+)

Surely it depends on what "up to" is supposed to signify? I've always considered that it refers to the fact that you will receive varying speeds which may not {always} be the highest but potentially sometimes could be. In that respect, FTTC is the same as any other product because if everyone who had it decided to download huge files simultaneously then nobody would receive the maximum speed. The available bandwidth isn't 40Mbit * # users.

Some information here which may be relevant, although it doesn't mention "profile". I think I remember reading something else about it a couple of weeks ago:

"The approximate doubling of the FTTC speeds will be possible because BT is increasing the amount of optical spectrum allocated within the fibre services from 7MHz to 17MHz, the spokesman said. "We don't need any new hardware — it's just tweaking the network," he noted, adding that this made the upgrade almost cost free.

BT did not launch its FTTC services at the higher speed because it did not at the time have permission to do so from the NICC, the UK's network interoperability technical forum, BT's spokesman said. Nick Ireland, who heads up the NICC's testing working group and is also BT's UK industry liaison, told ZDNet UK on Thursday that this permission was granted about a week ago."

OK, that's the fatter profile - using more bandwidth (and a bigger frequency range) on the copper cables and widening the PSD mask. Nothing to do with optical spectrum or fibre network at all, ironically.

VDSL 2 profile 17a if you're interested.

Distance from cabinet is the decider of speed really. The available bandwidth is at least 15Mbit * # users so even at 80Mbit/s line rate there's zero chance of contention between cabinet and exchange. Anything individual operators want to do to contend further is of course up to them.

Any reason for 2 lines? also interesting about the fiber slots

may I ask where you got these percentages from.

Originally took IDnet, for the faster upload speed (which is also not metered) and static IP for work use, to replace one of my ADSL connections. I believe in having at least two Internet connections because sods law one won't work when you really need to do something online fast. I suppose I could use mobile broadband but never really gave it much consideration years ago and it's still unpredictable. I could have saved and cancelled the other ADSL, that I recently switched to BT Infinity, but because I wanted to keep that phone line anyway, and Infinity Option 2 is now truely unlimited, I decided to keep give that a try. I'll debate the need for them both, again, next year. I know of someone who has two ADSL24 connections running with MLPPP (bonded) via a RouterBoard router. So he could potentially be getting 40Mbit upload by the end of this year.
