You make it sound like ADSL is an alternative to ISDN.  It's more correct
to think of ISDN as an alternative to POTS.

ADSL is designed to work in addition to an existing telephone connection -
either POTS or ISDN.  BT claim that offering both POTS+ADSL and ISDN+ADSL
would cause unacceptable interference, and so offer only POTS+ADSL. 
ISDN+ADSL is commonly available in other countries though.  It has
significant advantages - two simultaneous conventional calls, rock-solid
digital connection etc.

We were rather behind in the implementation of ISDN when ADSL came along,
and given BT's refusal to offer both together it has rather killed the
market for ISDN, but arguably we're the ones who are using old technology
in the UK with POTS+ADSL.  More advanced countries offer ISDN+ADSL.
