Well aren't BT claiming that BB is now within reach of some 98% or is that not right?...

It may be that 98% of people 'live in an area served by a broadband-enabled exchange'.
It doesn't mean that everyone in that area can get broadband though.

Well just how far does the wiring extend from a BT exchange?, AFAIK BB connections are possible, tho not that fast!, up to some 7-8 Km....
It's not the distance, it's the attenuation...
With a 50V ballast resistor bridge (50 ohm elements), a modern telephone incorporating ASTIC, and 20 lb/mile UG cable, 570 ohm line loop is the max permissible resistance for 60mA transmitter current, equating to
6.45 miles. [Atkinson]. (This was when trunk lines were cabled in up to 100 lb/mi.)I expect loop length was pushed further when electronics got pushed into local exchanges.
Bandwidth deteriorates rapidly with line length; which means that broadband-users located beyond 3.8 miles (6 kilometres) from their local telephone exchange are restricted to 1Mbps or less.

Wonder if it's the same guy who keeps calling me from India saying "Helo how arre U today. You have been selected at random... and have wona free ". Never found out what it was as I put the phone down. Blimey, hope it's not NTL support!
Arguably much the same thing;).....
is what people find the best attribute...
Jezzzz thats going some!....
