This sounds like a good idea. From where I'm standing, 
telco might have issues co-locating a mux in their 
facility for E3.

What I can see happenning more quickly is having the mux 
at our PoP, and getting the telco to provision E1 
circuits (up to 16) into the mux, then breaking out as an 
E3 into the PA-MC-E3 port adapter and do the nx64Kbps in 
there. Does this sound like it can work?

Cheers,

Mark.
