摘要:
A wireless extension of the IEEE 1394 bus where two clusters of 1394 devices are linked by a wireless bridge. The device clusters communicate without being bridge-aware. The wireless bridge provides for a bus reset isolation. The wireless extension including a buffer memory for storing self-identification packets in the 1394 interfaces of both boxes of the wireless bridge. With these buffer memories the self-identification packets of the bus stations in the other cluster can be collected and they can be read out during the self-configuration phase of the network after a bus reset when the bus grant is assigned to the box of the wireless bridge that is also connected to the bus where the bus reset has occurred. The physical layer block of the 1394 interface transmits artificial self-identification packets for all bus stations of the other cluster.
