Abstract
The invention is a circuit which permits spare circuit packs to replace operational circuit packs while keeping peripheral circuitry apprised of the status of the packs. The circuit receives signals from a first conductor and returns the signals to the conductor so that a spare circuit pack can be removed without affecting the signals to the peripheral circuits. The circuit also detects the signals on a second conductor and applies the same signals when a circuit pack including the circuit is reconnected. The circuit also includes elements which prevent loading down the conductors while power from the circuit is cut off or during power up.
