SONET. That's what it's for.  It's dedicated isochronous bandwidth on a 
shared circuit, designed to let you merge them together onto a faster 
circuit and back out again.

You think when you make an ISDN call you're not getting a 64kbps dedicated 
circuit for the duration of the call?

In any case, when you lay cable, you lay down way more than you need, 
because the cost of the physical cable is trivial. THe first guy who asks 
for a connection causes 900 pairs to be laid. The next 899 require none of 
that work.
