摘要

Synchronous telecommunication networks, distributed control systems and integrated cir cuits have its accuracy of operation dependent on the existence of a reliable time basis sig nal extracted from the line data stream and acquirable to each node. In this sense, the existence of a sub-network (inside the main network) dedicated to the distribution of the clock signals is crucially important. There are different solutions for the architecture of the time distribution sub-network and choosing one of them depends on cost, precision, reliability and operational security. In this work we expose: (ⅰ) the possible time distribu tion networks and their usual topologies and arrangements, (ⅱ) How parameters of the net work nodes can affect the reachability and stability of the synchronous state of a network. (ⅲ) Optimizations methods for synchronous networks which can provide low cost archi tectures with operational precision, reliability and security.
