Abstract:
1. A device for coupling local area network packet-based digital data signals between first and second network cables each having first and second wire pairs, the first and second wire pairs of the first cable also defining a phantom channel for carrying a first signal, the device comprising: a first signal transformer having a primary winding and a secondary winding, said primary winding having a center-tap connection, said first signal transformer being operative to pass local area network packet-based digital data signals; a second signal transformer having a primary winding and a secondary winding, said primary winding having a center-tap connection, said second signal transformer being operative to pass local area network packet-based digital data signals; a first local area network connector having a first contact pair coupled to said primary winding of said first signal transformer, and a second contact pair coupled to said primary winding of said second signal transformer, for connecting said primary windings of said first and second signal transformers to respective ones of the first and second wire pairs of the first local area network cable; a second standard local area network connector having a first contact pair coupled to said secondary winding of said first signal transformer, and a second contact pair coupled to said secondary winding of said second signal transformer, for connecting said secondary windings of said first and second signal transformers to respective ones of the first and second wire pairs of the second local area network cable; a third connector having a first contact coupled to said center tap connection of said primary winding of said first signal transformer and a second contact coupled to said center tap connection of said primary winding of said second signal transformer, for connecting said center tap connections to the phantom channel defined by the first and second wire pairs of the first cable; and a single enclosure housing said first and second signal transformers and said first, second and third connectors.
