    摘要： A network switch including a plurality of first network ports, a plurality of second network ports, a first bus, a second bus and a bridge interface coupled between the first and second buses. The first ports receive and transmit network data according to a first network protocol and the second ports receive and transmit network data according to a second network protocol. The first and second buses operate according to different bus standards. The bridge interface enables data transfer between the first and second buses and thus between the networks operating at different protocols. The switch includes a switch manager that controls the flow of network data and a processor for performing supervisory and control functions. The bridge interface includes receive buffers and transmit buffers assigned to respective ports. During packet data transfer operations across the first bus, the bridge interface emulates a first network port. During packet data transfer operations across the second bus, the bridge interface primarily acts as a slave to the second network ports by storing control lists for execution by the second network ports. This processor is relieved of performing necessary overhead functions associated with the second bus and is thus freed to perform other important switch functions.

    摘要： A direct media independent interface (DMII) connection for a network device including a data link circuit, a connector, a clock circuit and a crossover connection. The data link circuit includes a reconciliation circuit that transmits and receives signals according to the MII standard. The clock circuit asserts at least one MII clock signal on the crossover connection to synchronize data transfer. The crossover connection crosses MII transmit signals with MII receive signals. A grounding circuit is optionally provided to ground one or more of the MII signals that are not required for the DMII connection. The connector may be a standard MII connector, or may be implemented as a minimum or reduced profile connector for carrying only the desired MII signals. The crossover connection is performed internally within the DMII port, or externally by a crossover cable. The cable is a standard MII cable, or is implemented as a minimum or reduced profile cable. The clock and ground circuits may be incorporated within either or both DMII ports, or may be incorporated within a crossover cable.

    摘要： An adaptor allows a magnetic stripe card reader to receive information from other media such as wireless proximity chip cards while maintaining the ability to receive a magnetic stripe card. In accordance with one embodiment, the adaptor includes a simulacrum structure of sufficiently narrow width to fit substantially permanently within the slot of the magnetic stripe reading device, while providing sufficient room for a magnetic stripe card to also be concurrently accommodated within the slot and read by the reader head. The simulacrum structure may be in electronic communication with one or more transceivers of wireless communications such as RF and IR.
