Abstract
A system includes a communication device that includes a number of interface cards and a switching complex. Upon receiving a data signal, an input card modifies header bits of the data signal to identify an input port on which the data signal was received. The switching complex uses the modified header bits to communicate the data signal to an output card and associated output port. In a particular embodiment, the switching complex may also modify header bits to identify the input card.
