This is a special case of my overall concern with interoperability. I believe 
EFM should provide a clean and extensible framework; however, leave too much 
functionality left open to the implementation, and then you'll get 
incompatible implementations.

ILEC needs are just different. It's not because we like to be conservative. 
We have to. Legacy is important, keeping customers is important., and 
offering a service that is at least as good as the existing one is of utmost
