This attribute specifies the committed information rate (CIR), and
represents the rate at which the network FRF.5 ATM VCC agrees to
transfer information under normal conditions. A conservative CIR
value would be the sum of the CIRs of all the individual FrAtm
Dlcis multiplexed by the VCC.
The cir is converted into ATM service parameters according to the
conversion policy specified by the connectionTransferPriority
attribute. The conversion policy is defined under the ModuleData
FrameRelayService AtmNetworking TransferPriority/n component.
