Central Controller |
(Glossary) |
When operating in Trunking communications mode, the central controller assigns base station repeaters as voice repeaters or data-only control channel repeaters. The base station repeater assigned as the control channel continually sends a background data word. The background data word (generated by the central controller) continually provides synchronization for the system. Through the control channel, the central controller also continually sends out an Outbound Signal Word (OSW). This OSW contains the System ID and is transmitted at least once every three seconds.
