Redundancy in voice and data communications systems
Abstract:
A method includes receiving information at an interface circuit and providing the information from the interface circuit to a processing circuit through a direct communications path between the interface circuit and a processing circuit, which processes the information received from the interface circuit. The method further includes providing the information from the interface circuit to the processing circuit via a crosspoint switch in response to a failure of the direct communications path, wherein the direct communication does not pass through the crosspoint switch.
