If your CIR and your port speed are the same, then:
CIR=64000 (port speed of local router)
Bc=8000 (port speed of remote router divided by 8)
Be=64000 (port speed of remote router)
MinCIR=64000 (Carrier enforced CIR)
Tc=Bc/CIR
Tc=8000/64000
Tc=.125
In this scenario, you will not have any burst capability, because your
port speed is equal to your CIR.
Does that help?

Dear all,
Under FR environment, when CIR equal to Access Rate, how the excess
burst rate (Be) work? For example, 64K=CIR, Tc=1 seconds, Bc=8000Bytes,
Be=9000Bytes. Can I say: it can't burst to 9000Bytes within one seconds
because it over the access rate?
Anyone can clarify these parameters?
