What are you talking about.  You can go back and tell your provider
that you are losing one packet per 10^-5 and expect them to actually
do something to fix it with a leased line.  You can't do that with FR
unless your PVC CIR is wire speed or you traffic shape to your CIR.

Who do you buy leased lines from?  Nobody we buy from.  If you are
talking about a tiny provider buying a T1 from a larger IP provider,
you might want to find another provider if that is your impression.  I
think the discussion was building a backbone though.
