Method and apparatus for border node behavior on a full-duplex bus
First Claim
1. In a full-duplex communications system having plurality of nodes, wherein one of the nodes is compliant with IEEE P1394b high-speed serial bus standard and receives a Self-ID packet from a high-speed serial bus connecting the plurality of node, a method for determining and communicating the existence of a hybrid bus comprising the acts of:
- examining received Self-ID packets by IEEE the P1394b compliant node for the absence of a Speed Code; and
determining the existence of a hybrid bus if any of said received Self-ID packets do not contain a Speed Code.

Abstract
A method for determining and communicating the existence of a hybrid bus In a full-duplex communications system having plurality of nodes, wherein one of the nodes is compliant with the P1394b standard and receives a Self-ID packet from the bus, comprising the acts of examining received Self-ID packets by the P1394b compliant node for the absence of a Speed Code; and presuming the existence of a hybrid bus if any of the received Self-ID packets do not contain a Speed Code.

3. A computer-readable medium containing instructions which, when executed by a computer, determine and communicate the existence of a hybrid bus in a full-duplex communications system having plurality of nodes, wherein one of the nodes is compliant with the P1394b standard and receives a Self-ID packet from the bus, by performing the acts of:
