ABSTRACT:
In a "Futurebus+" backplane, at each end of the backplane the signal lines are each electrically connected to a power bus spaced from the rear face of the backplane via a discrete resistor which is housed in a throughbore in a body of electrically insulating material detachably secured to the rear face of the bakplane and which is electrically connected between the power bus and a pin soldered in a plated through hole and interconnected in the signal line. The ground lines are each connected to the power bus via a discrete capacitor which is housed in a throughbore in the body and which is electrically connected between the power bus and a pin soldered in a plated through hole and interconnected in the ground line. In the event that a resistor or capacitor should be faulty, only the signal or ground line to which the faulty resistor or capacitor is connected will be out of service until the faulty resistor or capacitor is replaced.
