If the end-device cannot achieve 19 1207 dBm EIRP, the Max EIRP SHOULD be communicated to the Network Server using an out-of- 1208 band channel during the end-device commissioning process. 1209 2.9.4 CN470-510 Join-Accept CFList 1210 The CN470 LoRaWAN supports the use of the OPTIONAL CFList appended to the Join- 1211 Accept message. If the CFList is not empty, the CFListType field SHALL contain the value 1212 one (0x01) to indicate the CFList contains a series of ChMask fields. The ChMask fields are 1213 interpreted as being controlled by a virtual ChMaskCntl that initializes to a value of zero (0) 1214 and increments for each ChMask field to a value of three (3) for 20 MHz plans A or B and two 1215 (2) for 26 MHz plans A or B.
