ATM doesn't necessarily mean 155Mbps. It's just that before Gig-E, the common Layer 2 protocol that offered more than 100Mbps was ATM, on the back of DSL backhaul deployments. If memory serves, ATM also went as far as STM-4/OC-12 speeds, although STM-1/OC-3 was more common. In this case, I'm recommending POS (which calls for PPP or HDLC Layer 2 encapsulations), much more efficient than ATM. > What about redundancy, is redundancy needed in a POP of > this size? Not sure, depends on the OP. I'd say add redundancy in if you can, always, but it's always a function of budget and need.
