Some will get 250 megabits down, some 25 megabits. 35b Supervectoring often reaches speeds over 200 megabits by using twice the spectrum, 35 MHz. (Hence the name, 35b, used by most engineers.) DT has been condemned for not delivering the promised speeds and hiding that with "up to" figures. They've now announced that the "up to 250 megabit" 35b homes will get a minimum of 103 meg down.
It was originally promised for ~2015 but the vectoring engine is just reaching reliability. DT had pushed the 35b operational date back to 2019. Höttges in the financial call now says they will turn on 35b in 2018.
Whenever DT turns on the higher speeds, they will quickly reach 15M homes.
That implies the units going into the field today support the 35 MHz on the physical layer. They won't turn them on for now, because without the vectoring noise-cancellation the speeds will be much lower.
Timotheus Höttges CEO said, "At the end of 2018, our fiber coverage will be around 80%, by the way, as always promised and our speeds will step up massively with super vectoring. At the end of this year, already 15mm and I repeat that, 15mm German homes will have access to speeds of up to 250 megabits per second."
He also raised the promised vector deployment from the previously 80% to "85% to 90%" in 2019.
A decade ago, German official Mathias Kurth predicted DT would have to upgrade the 65% of Germany that had cable. It was unnecessary to give them a subsidy or concessions. Since then, DT has chosen to play a game of chicken with the government. They've claimed they needed either a subsidy or the ability to decimate competition. They held hostage the German homes deprived of a better Internet. Kurth's successor, Jochen Homann, initially resisted DT's demand to raise the unbundling prices to give the incumbent a bigger advantage.
Since then, cable has taken share. Kabel Deutschland offered twice the speed for the same price. DT did only a very cheap upgrade to VDSL without adding additional remote cabinets. That allowed them to advertise "up to 100 megabits." Few receive even half that. They've now added vectoring to perhaps a third of the lines, which allows higher speeds but still usually less than advertised.
