Conventional base station interface architecture for RF trunking multisite switch
摘要
An interface for a conventional base station into a digitally trunked network of RF communications systems acts a pseudo-down link from a multisite switch to a trunked site controller. The interface monitors the conventional channels from the base station and sends a channel assignment message to the multisite switch when it detects a voice signal. The channel assignment message notifies the trunked RF systems that a new call is active so that each system can assign a trunked working channel to the conventional call. Similarly, the multisite switch sends a channel request when a trunked call is to be broadcast over a conventional channel. The interface keys the channel and couples the channel to the trunked call.
