Hi Mike,
These are Cisco definitions. Take the trouble to read this document:
http://www.cisco.com/en/US/tech/tk713/tk237/technologies_configuration_e
xample09186a00800942f8.shtml
Basic Cisco definitions are as follows:
access rate
-Cisco's definition for the physical line speed, or port speed.
frame-relay cir
-To Cisco, CIR is the average rate defined by the problem statement, in
bps.
-Cisco defines rate given to you by the telco as the "mincir", not CIR.
-Default cir is 56000 bps.
frame-relay mincir
-The telco/ISP guaranteed rate.
-By default, mincir is equal to half of the cir, in bps
mincir = cir/2
