Kind Code:
B2
Abstract:
A timing control arrangement that dynamically controls the distribution of timing information in a distributed digital communication system. A reference timing signal is distributed from a reference master node 1 to all other nodes 2-6 in the system. The distribution is accomplished on a dynamic basis without the use of a central control. Each node is connected by links 101-111 to at least one other node and each node receives timing signals from all of the links to which it is connected. Each node selects one of these signals as its timing reference by scanning the various signals it receives to identify the one signal that is applied via a link path that is the <> to the master reference node as indicated by information specifying the number of intermediate nodes through which the timing signal has traveled from the reference node to reach the receiving node. This decision is based on a set of bits included in the timing signal transmitted by each node indicating the number of intermediate nodes between itself and the reference node.
