The list of data rates supported by the end-device SHOULD be communicated, as part of the 1553 device profile, to the Network Server, using an out-of-band channel during the end-device 1554 commissioning process. 1555 For a network to enable use of these data rates on existing channels, for example added using 1556 CFList, it is necessary to use a NewChannelReq MAC command to modify the DRRange 1557 using the values indicated in Table 68. To add an additional frequency using NewChannelReq 1558 the values of DRRange listed in this table are used. 1559 1560 Configuration DRRange Description of Example Configurations MaxDR MinDR DR0 to DR5 5 0 Minimum set supported for certification.
