They are not the first to trial or even rollout 50Mbit in the UK.
Ask4 are, with their 50Mbit symetrical.
Maybe first DOCSIS 3.0 50mbit ?
Probably refers to cable (coax) service in general. Symmetrical and DOCSIS of any type do not usually get along. That Ask4 50/50 symmetrical tier is for Fiber. FTTB= fiber to the bungalow
