RE: CIR in FRTS

You mincir could just as easily be 48k given that the service provider has
given you a CIR of 48K, you will always have that amount of bandwidth, if
adaptive shaping is on you transmission rate can be dropped to mincir not
cir.

So I would use mincir because in an adaptive shaping scenario if you used
CIR you could end up only transmitting at 24k a sec

Hi Minha,

If your contract with SP states "during congestion your provider will mark
any traffic in excess of 48 kbps as discard eligible ", your CIR is 48Kbps
and your Peak information rate would be 128kbps. and Tc is 125 ms
