With DSL, modem to local phone exchange is not shared, but I suppose
that what happens beyond that nobody can say as it is too varied. (?)
I understood local Quest to use ATM to my ISP, but it shouldn't matter
to me because Quest guarantees the transfer speed (to 256/128 ?), but
I think they've got it set up to guarantee (or at least almost always
provide) 640/128.  Quest and the ISP decide on protocols I need to
tell my modem to use to talk with the ISP.  I was told it is PPPoATM.
But I communicate via plain TCP/IP and no PPP-anything; the modem is
a router.  Some ISPs configure the modem as a bridge so it looks to
your system like one of your ISP's NICs extended to your site.

From what I've seen, Quest is near-100% reliable as long as you don't
need to deal with so-called customer service for service changes, etc.,
and low hassle, while Cable is plagued with game-playing like frequent
downtime, not allowing servers, sharing subnets, etc.  The extra speed
would be nice, though.
