Disclosed is a method for distributing customer contacts to a transaction processing entity of a transaction processing system. The method includes evaluating, by the first storage processor and as part of a first batch process, the set of enclosures relative to a set of identification rules. Crate storage unit may comprise a platform for receiving packed crates and a second platform for receiving empty crates. This enables various layers to be shared between the switches and the components. If the switching mechanism positions the drive mechanism adjacent to the drive surface of the first rail, then the drive mechanism engages the drive surface of the first rail to move the accessor along the first rail. The first tri-state element is controlled by the first pulse signal to enable the test data input signal to be latched when the test enable signal is in the first state.
