DME channels are allocated per RTU. How many channels are dedicated to each RTU?

Explanation:
DME channels are allocated in pairs to each RTU, giving two channels per RTU. This setup provides redundancy and capacity: if one channel experiences interference or needs maintenance, the other can continue handling interrogations and replies, ensuring continuous DME operation for aircraft. The two-channel arrangement also aligns with how DME/TACAN systems use paired frequencies, helping to maintain reliable distance measurements across the network.
