The device variant engineers can create device variants with different SIP configuration settings. The device variants are shipped with the device. </p> <p>The engineers configure the Keys based on the Key Space design to create the device variants at the time of device creation. The device variants are stored in the device. </p> <p>Standard CenRep based tools can be used to create the device variants.
