Abstract
In a trunked communications network, a multiple site information distribution control 'switch' (multisite switch) provides access to digitized audio and control signals from various audio sources to one or more audio destinations connected at various 'nodes' in the multisite switch. A dedicated Network Interface Module (NIM) is provided in the multisite switch to facilitate interconnection and communication between multiple networks of similar multisite switch controlled architectures to create an 'extended' mega-network. The NIM allows an entire remote network to appear as a just another multisite switch node in a local network and vice versa. A trunked communications network having a NIM can communicate through this 'node' with other networks having a NIM, thus establishing inter-network communications in a manner that is essentially transparent to users in either network. The use of a plurality of NIMs per multisite network allows connection of multiple networks together, for example, in a 'star' or series configuration, to greatly expand geographic coverage.
