Which option lists the three layers of information in the DMR network window?

• A. DMR network level (1); DMR online ITU level (2); ITU specifications (3)
• B. DMR network level (1); DMR online ITU level (2)
• C. DMR online ITU level (2); ITU specifications (3)
• D. ITU specifications only

Answer: (A)

In the DMR network window, information is presented in three layers. The top layer shows the DMR network level, which covers the network’s own configuration and status within the DMR system. The middle layer is the DMR online ITU level, reflecting how the network aligns with ITU-related online parameters. The bottom layer lists the ITU specifications, i.e., the formal ITU standards that apply. Having all three layers together gives the complete picture: the network’s identity and status, how it fits with ITU online criteria, and the specific ITU standards governing it. Any option that omits one of these layers misses essential information, which is why the full three-layer combination is correct.
