I think this is a non-issue, considering that with the next generation of
IP-only boxes ATM will become hopelessly useless.

Better yet, the real big boxes are removing any need to do clustering, so
the average number of IP hops for an NSP is going to be like 3 or 4.

Don't forget about ss7 bypass. It may get even better than you
can imagine at the moment.

SS7 (or any other sort of PSTN relationship) has absolutely
*nothing* to do with this.

Let me guess -- you worked for Bell Labs in a previous life?

Like IP over raw fiber. Our friendly WDM vendors would love to get rid
of SONET. SS7? What's that? :wink:
