IMHO:

This is what I thought happens - Just a guess (probably get flamed )

DSL represents the connection between client and telecoms atm network. Which
seems to establish some form of "ppp" type connection across telecoms ATM
network. This represents the connection between client and ISP. Telecom
charges the dsl user on a usage based system.

If the ISP did not connect to the client through the ATM network then they
would probably need ISDN T-1 circuits to take the incoming modem calls and
the appropriate modem hardware. Ie they need a modem and 1/24th of an T-1
ISDN connection for each client. This is probably more expensive than the
ATM type solution because they need hardware and fixed bandwidth per client
ie each modem requires 64kbs.

Now I assume what ISPs rely on is that not everybody thrashes there internet
connection so they will "concentrate" all their clients going through one
Internet pipe. The speed of this pipe only needs to be good enough to
maintain their customers perception of Quality of service.
