There are still hidden costs associated with PNI at PAIX type
facilities. Have you ever tried to disconnect a PNI or CNI after you've
upgraded to a higher port size? It is not as easy as it might seem. The
up side to telco based private interconnects is that it allows for
greater network diversity in metropolitan areas where more than one
interconnect location exists.

The real problem that I see is how do you realistically expect to dump
an OC48s worth of IP traffic on another backbone in one place wihtout
effectively destroying their network? It continues to amaze me how
everyone wants to sell settlement based peering or restricted transit
when their networks are no where near the size, capacity-wise, to offer
that service.

Are there any other suggestions, other than ATM?

Cross-connects ala PAIX & Equinix models.

Fewer opportunities for provisioning delays and/or back hoe trauma.

A cross-connect inventory is much easier to manage, troubleshoot during an
outage, and grow into larger amounts of capacity than a mix of circuits
ordered from ever changing / merging carriers.  Just think about how many
people-hours are wasted in the direct circuit process if a merger gets in
the way and one side of the peer suddenly has to order capacity over a
carrier not in your facility because their MSA is in the way... hmm.

Better yet, how many folks get pulled into conference calls trying to
troubleshoot circuits when they have gone down...  This expense is rarely
calculated in cost model projections....
