This is a plain-language description explaining what a specific FNB connection configuration actually does, meant to be read directly by an admin instead of decoding the encoded ctFDDINMConfig string. It lets an admin pick the right configuration option by name rather than parsing cryptic connection codes. For example, a description reading "Dual counter-rotating ring, both MACs active" tells the admin exactly what wiring topology config ID 2 represents without decoding the ASCII connection string.
