Short Introduction into IEEE 1394

IEEE 1394 in fact defines two types of hardware implementations for this bus system, cable and backplane. The only one described here and supported by the Linux subsystem is the cable implementation. Most people not familiar with the standard probably don't even know that there is something else than the 1394 cable specification.

If you are familiar with CSR architectures (as defined in ISO/IEC 13213 (ANSI/IEEE 1212)), then you already know quite a bit of 1394, which is a CSR implementation.
