Table 37: AU915-928 ChMaskCntl value table 921 If ChMaskCntl = 5 then the corresponding bits in the ChMask enable and disable a bank of 8 922 125kHz channels and the corresponding 500kHz channel defined by the following calculation: 923 [ChannelMaskBit * 8, ChannelMaskBit * 8 +7],64+ChannelMaskBit. 924 If ChMaskCntl = 6 then 125 kHz channels are enabled, if ChMaskCntl = 7 then 125 kHz 925 channels are disabled. Simultaneously the channels 64 to 71 are set according to the ChMask 926 bit mask. The DataRate specified in the command need not be valid for channels specified in 927 the ChMask, as it governs the global operational state of the end-device. 928 929 2.6.6 AU915-928 Maximum payload size 930 The maximum MACPayload size length (M) is given by the following table for both uplink 931 dwell time configurations: No Limit and 400ms. It is derived from the maximum allowed 932 transmission time at the PHY layer taking into account a possible repeater encapsulation. The 933 maximum application payload length in the absence of the optional FOpt MAC control field 934 (N) is also given for information only. The value of N might be smaller if the FOpt field is not 935 empty: 936 937 938 939 940 941 942 943 944 945 946 947 948 949 Table 38: AU915-928 maximum payload size 950 The greyed lines correspond to the data rates that may be used by an end-device behind a 951 repeater. 952 For AU915-928, DownlinkDwellTime MUST be set to 0 (no limit). The 953 400ms dwell time MAY only apply to uplink channels depending on the 954 local regulations. 955 If the end-device will never operate with a repeater then the maximum application payload 956 length in the absence of the optional FOpt control field SHOULD be: 957 958 DataRate UplinkDwellTime=0 UplinkDwellTime=1 M N M N 0 59 51 N/A N/A 1 59 51 N/A N/A 2 59 51 19 11 3 123 115 61 53 4 230 222 133 125 5 230 222 250 242 6 230 222 250 242 7 Not defined Not defined 8 41 33 41 33 9 117 109 117 109 10 230 222 230 222 11 230 222 230 222 12 230 222 230 222 13 230 222 230 222 14:15 Not defined Not defined DataRate UplinkDwellTime=0 UplinkDwellTime=1 M N M N 0 59 51 N/A N/A 1 59 51 N/A N/A
