If you are having trouble answering these questions, it might be time to take a refresher course on the role of nodes in a DMR network.
In a DMR network, there are nodes with two functions, a control node and a switching node. There is only one control node in a network, and in a multi-node network, the lowest numbered node is the control node.
To help you visualize what this explanation looks like, the course DMR Network Architecture: DMR Node Architecture includes a diagram that makes it easy to see the role of a control node.
For further information about switching nodes, watch the video below and read the accompanying DMR Node Architecture lesson. You can also take the full Introduction to DMR course on the Tait Radio Academy.
