Abstract
A device for coupling first and second bi-directional wired digital data signals to each other and to a data unit, for use with first and second service wire pairs installed at least in part in walls within a building. The first service wire pair concurrently carries the first bi-directional wired digital data signal and a first service signal carried over a first service signal frequency band, using frequency division multiplexing. The first wired digital data signal is carried over a frequency band distinct from the first service signal frequency band. The second service wire pair concurrently carries a second bi-directional wired digital data signal and a second service signal carried over a second service signal frequency band, using frequency division multiplexing. The second wired digital data signal is carried over a frequency band distinct from the second service signal frequency band.
