Small grey boxes with white numbers on every 100yards or so. If you have these then you are on TPON. It means you have fibre to the end of your street and only the last few meters is copper, this means ADSL is a while off for you yet. BT have been trying this sort of stuff on new housing estates that are quite far from the exchange.

If you don't the only thing you can do is head on over to http://www.bt.com/braodband and check the interest in your area.
