Abstract
An elevator system including a plurality of elevator cars, and a system processor for dispatching the elevator cars. The system processor provides floor address and address interpretation signals for the cars, which signals select whether or not a car is able to answer a corridor call, and when it is, the signals determine whether the car will consider only a corridor call from the addressed floor, or a predetermined family of calls using the addressed floor as a reference.
