Abstract
A system and method are shown for providing a fully synchronized two-way communication network having a number of transmission stations (10) and selective call receiving devices (27). Each transmission station (10) stores station identifying information and an updatable synchronization priority indicator. Periodically, each station (10) transmits a timing message that includes the station's identifying information, priority indicator, and information relating to the timing of the station's frame clock (45). When a given station receives a timing message transmitted from another station, it determines whether the other station is a direct upstream station thereof. The given station is responsive to a timing message from its direct upstream station for adjusting its frame clock (45) based upon the timing information contained in the message received from the direct upstream station. The given station thereby synchronizes itself with its direct upstream station. Each station also updates its stored priority indicator in the event that there is a change in the station's direct upstream station.
