PPP over SONET

I was thinking... as far as my limited knowledge allows..
It seems that PPP or HDLC over OC-3 would be faster than
ATM over the same OC-3 circuit, and (at this stage) have fewer
But you can configure PVC's with ATM, working with an ATM
cloud, similar to frame relay, no? And if this is the case, then
a large backbone-type provider may desire to set up an ATM cloud,
making it easy to add POP's (just add them to the cloud), and allow
for more layer 2 routing (just configure PVC's between every POP you
have, building a full web, and a traceroute would now travel 2 or 4
hops instead of 12...?)
instead of some sort of hierarchichal star topology, you'd
have a large web...
and one more potential benefit to ATM -- won't it scale
very well to OC-12? ie, when you want to upgrade your network to
OC-12, you'd have no changes to make?
just thinkin... and I love it when y'all correct me, I tend
to learn a lot :)
