See the figures in my sig. As you were told however, aluminium between you and the cab could screw things a bit.

My broadband basic info/help site - www.robertos.me.uk | Domains,site and mail hosting - Tsohost.
Connection - Plusnet UnLim Fibre (FTTC). Sync ~ 56.4/14.5Mbps @ 600m. - IPv4BQM IPv6BQM

In reply to a post by allofus:
My question is why does BT persist with VDSL2 when for longer real world line lengths VDSL gives better performance?



Does it?

From around 1200m the performance, according to that graph, is very much the same.


It is also wrong putting ADSL and VDSL directly together as there is a additional unknown line length before a cabinet. So for example a 400m VDSL line might replace a 4km ADSL

No idea at present. Currently running an ECI modem so no stats. The ECI gives a slightly higher speed than the Huawei - with a Huawei cabinet.

For the avoidance of douby you are getting Ethernet GEA which is delivered by Openreach -which allows 60+ service providers to offer FTTC service one Which BT Retail offer a product called ifninty (infinity can only be sold at >15 meg) other service provers such as talk talk. plusnet sky, ident - etc etc may offer a different product at different price points

And here is the test at 500m or so:

Don't worry about the Upstream - it is being restricted to 10Mb by the router!

The attenuation would be really interesting. Haven't you got a HH5?

And while they are pessimistic I get ripped apart from I give estimates saying they are too high at other times.

The fact I get slated for being both above and below suggests we are in the right sort of area.

Three different power masks are running, depending on the distance of the cabinet from the exchange, with the masking done to try and ensure existing ADSL and ADSL2+ services do no see any reduction in speed from VDSL2 cross talk.

So very much part of what Openreach deploy.

Best thing is for people to get speed tests onto our maps i.e. run with postcode supplied and we can over time compare this with our estimates and use that to refine things.

No!

And at present I have been asked to keep the ECI/2701 combination running. And I need the VOIP interface.
