Abstract
A data network has a bus to which are connected a given node, a parent node and a child node; and arbitration over acquisition of the bus is performed before data is communicated between nodes. Transition to an initial state in a self identification phase, in which the given node is enabled to respond to an arbitration signal received from the parent node, is controlled by receiving at the given node a SELF_ID packet representative of the child node, as well as the arbitration signal (SELF_ID_GRANT) from the parent node, which would enable the given node to transmit to the parent node a SELF_ID packet representative of the given node. The initial state is assumed at the given node, from which the SELF_ID packet is permitted to be transmitted from the given node to the parent node, if reception of the arbitration signal from the parent node is completed at the given node.
