This read-only bitmask reports security-related conditions detected by the terminal, including a link ID violation bit that flags when the RF link partner's identity doesn't match what's expected. An operator checks this bitmask to detect potential unauthorized or misconfigured link pairings rather than a plain RF quality issue. For example, the linkIdViolation bit being set could indicate someone connected the wrong remote terminal to this link, rather than a fading or noisy RF path.
