Which set of these MIR parameters are applicable depends on the interactions of other
parameter values. These interactions are described under
Setting the Configuration
Source
on Page 295. Also, where the Configuration Source parameter setting in the AP
specifies that BAM values should be used, they are used only if Prizm is configured to
send the values that it stores for the MIR parameters.
MIR Data Entry Checking
Uplink and downlink MIR is enforced as shown in
Figure 20.
NOTE:
In these figures, entry refers to the setting in the data rate parameter, not the
burst allocation parameter.

For example, in the Canopy SM, if you set the Sustained Uplink Data Rate parameter to
2,000 kbps and the Sustained Downlink Data Rate parameter to 10,000 kbps, then the
uplink and downlink MIR that will be enforced for the SM can be calculated as shown in
Figure 21.
