PRI* is often provisioned on fibre (although more and more often over
existing copper if available), just like E1 lines.  BRI** is provisioned
on copper almost exclusively.  At least, that's what's happening in .uk
and I'd be extremely surprised if it were radically different in .us.

* - aka ISDN-30
** - aka ISDN-2 (or ISDN-2e)
