ABSTRACT:
A multipurpose bus connects subsets of intercommunicating modular circuit packs in a complex electrical system. An individual one of the subsets may use the bus leads to transport signals differently from the other subsets. Each of the subsets of the circuit packs is selected to use the bus in particular time intervals. The subset, thus selected, uses the bus leads the way its own protocol governs during those particular time intervals and otherwise ignores the bus.
