    Nope, you will either be connected to one or the other. If you're out of spec for VDSL they will not install it and you will have to stay on ADSL

    Different entirely. In fact a line that has both sitting on it will be drowned out by VDSL.
    VDSL is a much higher bitrate the drawback of the technology is the range of it is hampered.
    The type of broadband gets jumpered on at the exchange or cab. Basically a wire gets run from the outbound side of a broadband port and stringed to the casewire feeding up to your property.

    Very basic:

    - ADSL and VDSL can not co-exist on the same copper pair.

    - ADSL always comes from the exchange.
    - ADSL can reach 5-6km

    - VDSL may come from the exchange or come from a fibre cabinet.
    - VDSL can maximum reach 2km, but is only really useful at 500-800m.

    Before my switch to FTTH I had the choice of staying on 15mbit adsl or switching to 12mbit VDSL. I think all new customers had no choice and had to go for VDSL if it was available to them.
    I'm about 1500m from the exchange.
