When we select the adaptation rule “min”, how are the operational CIR/PIR rates of a...

The administrative PIR values are ignored and both operational rates are set to the minimum residual rate allowed by the hardware.

The administrative PIR value is ignored and both operational rates are set to the administrative CIR value.

They are chosen as the largest multiple of the hardware rate step that is less than or equal to the corresponding CIR/PIR administrative value.

They are chosen as the smallest multiple of the hardware rate step that is greater than or equal to the corresponding CIR/PIR administrative value.
