Abstract
A rate adjustable backplane includes a set of switch slots configured to receive one or more switch cards forming a switch core and a plurality of line slots each configured to receive a line card. A low speed bus couples the line slots to the set of switch slots. A high speed bus also couples the line slots to the set of switch slots. Each line slot includes a low speed connector coupled to the low speed bus and a high speed connector coupled to the high speed bus. The low speed connector is adapted to receive a mating connector of a line card to establish a low speed communication connection between the line card and the switch core. The high speed connector is adapted to receive a mating connector of the line card to establish a high speed link between the line card and the switch core.
