You can put a Frame Relay Protocol Analyzer between your Router and
Provider's Last Mile facility to see what is really happening in the Link.
If your traffic will get lowered below what was in the LSA, you can complain
to your provider, above your CIR min [Cisco term] then it is just OK to
burst to the Max Speed your port can handle [it depends 2ur provider if they
have a fee for this excess burst or just free].
