A sequence of cards is stored that graphically represents available options within an information system. The conveyor includes a continuous first chain and a continuous second chain extending parallel to the first chain. A fourth ejection opening array is disposed between the first ejection opening array and the second or third ejection opening array. The RCMS reallocates idle RF resources between the network of cells whether those resources are redundant or not. Each of the stop ring and cavity control ring are moveable by separate actuators and a single control system. The resource managers of all intermediate nodes and all leaf nodes respond to their coordinating or intermediate nodes with an indication of supportability.
