Abstract
A technique for initializing a communications network having a ring topology chooses a ring master for each ring. The ring master communicates with all network nodes to assign each node a unique number. Upon power up, after all system clocks become stable, the ring master asserts a line that is normally used to delineate slots by holding the line for a predetermined amount of time. When a node is ready for operation, i.e. it has performed an internal reset procedure, and receives the asserted signal, it forwards such signal. Subsequent receipt of the asserted signal by the ring master indicates that the ring is operating properly.
