•We contemplated several architectures, including putting all nets on Junipers directly and using transitional cross-connects (tccs) that allow bolting ethernets to atms to sonets.

•Did side-by-side comparison of Cisco 6500 vs Extreme Black Diamond. Liked Extremes, but no oc12 atm, and winning feature was Cisco’s OSM-2OC12-atm 1483 bridged-routing blade
