Abstract
In a system for communicating between multiple signal sources and at least one destination, communications occur via a communications, line shared by the signal sources. The multiple signal sources are coupled to the shared communications line via respective interface circuits. The interface circuits operate to determine which signal source will control the shared communications line. The operation of the interface circuits involves a switching or enabling function responsive to signal activity from one of the signal sources. The switching operation also involves assigning relative priorities to the signal sources. The priortizing feature results from an interaction between the relative impedances of the signal sources and the destination.
