Abstract: A data network includes a plurality of network devices spaced apart from one another and distributed at multiple locations, a plurality of cables each coupled to a respective one of said plurality of network devices by a respective one of a plurality of first connectors, and a network hub including a second connector coupled to each of said plurality of cables. The network hub also includes a removable and replaceable termination element that mates with the second connector to provide signal connectivity between selected ones of said plurality of cables. The removable and replaceable termination element couples each of the plurality of cables to another of the plurality of cables such that any signal transmitted on the plurality of cables by the plurality of network devices both enters and exits said network hub at said second connector.

Abstract: A data network includes a plurality of network devices, a plurality of physical. transmission lines each coupled to a respective one of said plurality of network devices, and a network hub coupled to each of said plurality of physical transmission lines. The network hub has a removable and replaceable termination element providing signal connectivity between selected ones of said plurality of transmission lines. In one embodiment, the data network is installed within an aircraft including a fuselage, an empennage connected to the fuselage, a lift-generating surface coupled to the fuselage, and at least one engine for propelling the aircraft.
