The list of data rates supported by the end-device SHOULD be communicated, as part of the 644 device profile, to the Network Server, using an out-of-band channel during the end-device 645 commissioning process. 646 For a network to enable use of these data rates on existing channels, for example added using 647 CFList, it is necessary to use a NewChannelReq MAC command to modify the DRRange 648 using the values indicated in Table 11. To add an additional frequency using 649 NewChannelReq, the values of DRRange listed in this table are used. 650 651 Target Configuration DRRange Description of Example Configurations MaxDR MinDR DR0 to DR5 5 0 Minimum set supported for certification.
