The files take a little interpreting apparently, haven't yet looked at them myself.

Found my postcode - Lines = 100%, Uplift = 7.46 whatever that means.

If correct the large Zip files contains all the useful information. I don't know whether to be encouraged that my postcode appears in the list

it sounds as though uplift is the increase in speed that can be expected as a factor of average ADSL2 speeds... so if the average for your cab is (say) 3Mbps on ADSL2 you should expect about 22Mbps on FTTC.

That's my take on it anyway.

That's right and it's one of the metrics that BT use to decide whether to upgrade a cabinet to FTTC. i.e. too close to the exchange and the relative uplift is low compared to what ADSL2+ (direct from the exchange) can provide so they don't bother. Equally, as a little village near me has discovered, if the nearest cabinet is x miles away then none of the lines from the cabinet are short enough to provide an acceptable uplift and so won't be upgraded.

Thanks for the confirmation Simon.

It's nice to see that there is some logic behind things that BT do
