Abstract: front page image
(EN)A time synchronous method for Synchronous Digital Hierarchy(SDH) includes the following steps: the host node transmits the synchronous time information to the slave node by the section overhead; the slave node adjusts its own time to time synchronization according to the synchronous time information carried by the received section overhead. A time synchronous system, a host node and a slave node are provided in the present invention. By the present invention, adjusting the finger of the branch will have no effect on the synchronous time information, and the coding signal of the synchronous time information will not bring the phase changed in the process of transmission, so as to improve the precision of time synchronization.
(FR)L'invention porte sur une méthode de synchronisation de hiérarchie numérique synchrone (SDH) comprenant les étapes suivantes: un noeud hôte transmet des informations de temps synchrone à un noeud esclave par la section du dessus; le noeud esclave ajuste son propre temps au temps synchrone en fonction des informations de temps synchrone de la section reçue du dessus. L'invention porte également sur un système de temps synchrone, sur un noeud hôte et un noeud esclave. Du fait de l'invention, le réglage du doigt de la branche n'a pas d'effet sur l'information de temps synchrone et le signal de codage de ladite information n'induit pas de modification de phase dans le processus de transmission, ce qui accroît la précision de la synchronisation temporelle.
