Right, but math still works no matter which way you go. :) His math was
pefectly accurate to come up with the number in Bc.
But you're correct in that the Tc is actually derived by the router based on
the other parameters that we do configure. I (perhaps mistakenly) assumed
he was working something on paper...

You can not change the Tc value directly. You have change the Bc value to
affect the Tc. To figure out the Bc value use the following formula.
Bc=Tc*CIR
Default 125 ms per Tc
Bc =.125 * 128000 = 16000bps
For 10ms Tc
Bc = .01 * 128000 = 1280bps

Subject: Frame-Relay Traffic-Shaping (FRTS)
I am having some trouble working out the mathematics involved with a
particular Frame-Relay traffic shaping exercise. If I start with (CIR) =
128000bps and a (bc) =16000 and a (tc)=125ms and then change the (tc) value
to 10ms seconds, are the below calculations correct?
CIR = 128000bps
bc = 1280bps because (1/100) of 128 000 = 1280
tc = 10ms because (1/100) of 1000 = 10
Any help would be appreciated. Thanks in advance.
