  • the remote device 1207 determines whether the time of the communication device 12 or the communication device 20 is shifted by comparing the measurement values described in the test messages received from the communication device 12 and the communication device 20.

Abstract

La présente invention concerne un appareil de communication et un système de communication dans lesquels des anomalies peuvent être localisées dans des serveurs de temps et dans des réseaux dont les chemins de communication ont été rendus redondants. Un appareil de communication (10) acquiert des éléments d'informations relatives au temps depuis une pluralité de serveurs de temps (101, 102) par le biais d'une pluralité de réseaux (103, 104) et compare les éléments d'information entre eux, localisant de cette façon une anomalie dans les serveurs de temps (101, 102) ou dans les réseaux (103, 104). Un appareil distant (107) acquiert des éléments d'informations relatives au temps depuis l'appareil de communication (10) par le biais de la pluralité de réseaux (103, 104) et compare les éléments d'information entre eux, déterminant de cette façon une anomalie de l'appareil de communication (10).
