On a related note, why didn't Mexico choose to go with the "Gringo
Peeg" Bell System, and opted instead for the European one?  With the
onset of free-trade (hopefully), this might be a severe detraction.  I
suspect a call to Mexico would be routed to one of the International
Switching Centers (AT&T-speak) - and where's the closest one to San
Diego - Atlanta?!!!

Anyone care to explain what is it about the European telephone system
that makes it different from the Bell System that the two require
"internetworking with special-purpose routers"?  Is it just that we
use the North American Digital Hierarchy, i.e. DS-0,DS-1,DS-3, etc,
and that they use the CEPT?  Or is it more to do with Inter-Office
Signalling?

Thanks, and sorry for all the question marks,
