It's taken British telcos years to plan for this, and it's been put off a couple of times to deal with practical problems such as situations where you absolutely can't put fiber-to-the-premises in in any reasonable timescale.

This time they really seem to be determined to make it happen, even if it involves bizarro products like SOGEA, and if I recall correctly a sort of exchange-hosted baseband-only single-line DSLAM for the most intractable cases such as elderly people with no access to mains power - but even then it will implement the standard Digital Voice protocols, not the legacy DSLAM stuff.

"Copper wires, the kind of cabling used in landlines for over a century, can only carry a limited amount of data. They carry phone calls as a continuous electrical signal that mimics the original sound wave, which is what makes them analogue."

If someone reads this quickly, they might easily conclude that data is also transmitted as analogue sound signals (like a POTS modem) when ADSL has been around for many years and has pretty high throughput.
