If the end-device receives the Join- 1288 Accept message from one of the above downlink (DL) common join channels, the end-device 1289 SHALL use the corresponding channel plan 14 in the above table. 1290 1291 14 The corresponding channel plan can be determined by the uplink join channel, which corresponds to a pair of common join channels including UL and DL. The DL join channel is the channel from which the end-device receives the join-accept message.
