Hi,
Generally speaking, as long as there's more BW on the backbone,
no problem. But it does depend on circuit design.
The unwritten norm is CIR is 50% of circuit. The hardware stop
is port speed. If you have a fractional T1 with a port speed of
256K on a spoke, a full T on the hub and a CIR of 128K your
burstable to 256K, and also hardware limited to 256K.
Now if it's 3:30 PM EST and Cisco just announced a 500% increase
over projected quarterly gains, right after the fed announced
a 1.4% drop in unemployment on the last Friday of the quarter, the
same morning Pfizer announced they have successfully developed
a pill that does the same for women as Viagara does for men...
then maybe you won't get the burstable speed to 256K but you still
get the 128K. :-)

Subject: CIR on Frame-relay
Hi all
Quick question for you guys.
What happens if data transfer rate in frame relay exceed CIR?
Would there be a delay or retransmission?
What if Voice transfer rate in Frame relay exceed CIR?
Thanks in adv.
