What do these numbers mean?
- Control channel

- The other frequencies the site uses for calls. A trunking scanner follows them automatically once it has the control channel.

- RFSS (Radio Frequency Sub-System)
- A group of sites run by the same controller. Large Project 25 systems can have several.
- NAC (Network Access Code)
