Yeah, I could see that working. As another responder already, spans from 
multiple telcos are probably already synchronized to each other (or 
very, very close), so the card's framer can deal with the slight 
differences.

The difference between 1.544 and 2.048 is not something it can handle.

OK, I could have been mistaken, but it would surprise me if the card 
could handle it :-)

I agree; I don't know why it would work that way either.
