Abstract
A communication link for a dispatcher console to a multisite network of RF digitally trunked radio site transceivers and other dispatcher consoles. The communication link provides the dispatcher console direct access to a wide area RF network. A multisite central switch establishes audio and control communications between the different sites and various dispatcher consoles. The dispatcher consoles have audio and control links to the multisite switch. The multisite switch has a distributed architecture in which a switch node interfaces with the dispatcher console. A control communication protocol provides a standard format for message packets between the multisite switch and dispatcher console.
