Bluntly, everything has the caveat "UP TO"
People don't want another compensation scheme that want PROPER, RELIABLE Broadband. People have had enough of bamboozled, obfuscated "UP TO".
(Anyone that has tried to get compensation from the Electricity supplier for poor service will understand this fully. It's so much effort chasing these pointless compensation schemes, to get blood out of stone, than the time and effort it takes. They are a complete waste of fucking space, as are the regulators that run them). Importantly it is money that could be alternatively spent actually laying FIBRE.
Everything BT do regards ADSL, FTTC/VDSL2 aka Infinity1/Infinity2/Pointless G.fast over BT's sweated copper carcass legacy infrastructure is "UP TO".
I need to repeat that three times.
It's dependent on:
Cabling used: Aluminium/Copper twisted pair
Line Length of the Copper/Aluminium.
Quality of the connections on route/oxidation/dampness/exposure/age of those cables/connections.
Quality of the home wiring, removal of extension wiring.
Quality of Filter.
Matching of modems, i.e Broadcom (Home Router) to Broadcom (Distribution Card) etc.
Correct Firmware Updates (particularly G.fast)
Low Level Noise ('pump noise'), Industiral locations.
Quality of Power Supplies.
Any talk of hard and fast numbers like this (and then to spend 54 pages arguing over symantics) is absolutely ridiculous, and completely missing the point. There is so much that is subjective here.
This seems to be a smoke screen so we all end up arguing about numbers and compensation, when the argument has been moved away from the technology, which is the important bit.
We need to bring the argument back to the technology being used. Continuing to rollout Copper when so much has been paid in subsidies for Superfast "Fibre" Broadband is madness.
All lines longer than 500m (250m as the crow flies) need to have a policy of pure fibre rollout, nothing else.
There is no other realistic solution for these rural lines. Copper based "up to" 10Mbps is near here nor there.
It's pointless and can't be transitioned to faster speeds as they become necessary, especially quickly. These 500m+ lines if we go this route will have no upgrade path whatsoever.
