Assumes the chassis are connected in a line topologywith a typical selection of C Series modules containing a variety of timing architectures. Forinformation about network synchronization accuracy, visit and enter Info synchronization is system-dependent. Assumes a system containing one hop with optimizedC Series module selection.
