Abstract
A multisite network switch for a series of RF digital trunked radio transceivers and dispatcher consoles. The switch establishes audio communications between different sites and various dispatcher consoles. The multisite switch has a distributed architecture in which each node of the switch is supported by a microprocessor controlled card. These nodes perform all of the logical functions of the switch. When the switch is booted-up or reset, each node executes a dynamic address generation algorithm to select a unique address and resolve any address conflicts with other nodes.
