Well, order two FDDI ports at MAE-West, each into a router which has
two T3s back to your data center.  Each two T3s should be able to do
90mbits/sec of hdlc or ppp framing back to you, and route back and
forth from the FDDI.

Or order an OC3 'WAN' link, but plug it into an AIP card in a 75xx
and pull 3 T3s back to your main site.

Can a Cisco AIP speak ATM to the wan port of a Gigaswitch?
