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.

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.
