ChMaskCntl ChMask applies to 0 Channels 0 to 15 1 RFU .. .. 4 RFU 5 RFU 6 All channels ON The device SHALL enable all currently defined channels independently of the ChMask field value. 7 RFU Table 7: EU863-870 ChMaskCntl value table 373 If the ChMaskCntl field value is one of values meaning RFU, the end-device SHALL reject the 374 command and unset the "Channel mask ACK" bit in its response. 375 2.2.6 EU863-870 Maximum payload size 376 The maximum MACPayload size length (M) is given by the following table. It is derived from 377 limitation of the PHY layer depending on the effective modulation rate used taking into account 378 a possible repeater encapsulation layer. The maximum application payload length in the 379 absence of the optional FOpt control field (N) is also given for information only. The value of 380 N MAY be smaller if the FOpt field is not empty: 381 382 DataRate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 230 222 5 230 222 6 230 222 7 230 222 8:15 Not defined Table 8: EU863-870 maximum payload size 383 If the end-device will never operate with a repeater then the maximum application payload 384 length in the absence of the optional FOpt control field SHOULD be: 385 386 DataRate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 250 242 5 250 242 6 250 242 7 250 242 8:15 Not defined Table 9 : EU863-870 maximum payload size (not repeater compatible) 387 2.2.7 EU863-870 Receive windows 388 The RX1 receive window uses the same channel as the preceding uplink. The data rate is a 389 function of the uplink data rate and the RX1DROffset as given by the following table. The 390
