Abstract
A multiple cell lane switching system includes a number of individual cards interconnected via a plurality of cell lanes. Each card includes devices for receiving a plurality of cells from a transmission line and for buffering cells in an order corresponding to the received cell order. Cells are transmitted from a first card across the plurality of cell lanes to a second card in an order corresponding to that in which that they were received from a first transmission line at the first card. At the second card, the cells are read from the cell lanes and buffered. Finally, the cells are transferred from the cell lane buffers of the second card to a second transmission line in an order replicates the order of cell reception at the first card.
