ABSTRACT:
In synchronous digital communication systems using a synchronization quality marker (SSM), timing loops can be created. To avoid such timing loops, a synchronous digital communication system is provided having network elements (NE11, . . . , NE33) in which two classes (top, bottom) are defined for interface units (S.sub.1, . . . , S.sub.x, . . . , S.sub.X+i).
