The cable Phy sends one to three self-ID packets at the base rate (100 Mbits/s) during the self-ID phase
of arbitration or in response to a ping packet. The number of self-ID packets sent depends on the number
of ports. Figures 7

21 show the format of the cable Phy self-ID packets. Inside the GRF,
the first received quadlet of a self-ID packet is always 0000_00E0h, and the final quadlet is always the
quadlet containing the acknowledgement code.

21. Phy Self-ID Packet #2 Format
When there is only one node (i.e., one Phy/link pair) on the bus, following a bus reset, the GRF contains
0000_00E0h and the acknowledge quadlet only.
Example:
If there are three 1394.a compliant nodes on the bus, each with a Phy containing three or less
ports, the GRF of any one of the links is shown below. The FULLSID bit is assumed to be set
in this example.
