  • Method and device for returning to a normal communication link after using a standby link
    Patent number: 5367562
    Abstract: A data communication system comprises two links between two terminal equipments, a standby link being used in the event of malfunctioning of a normal link. A method of returning to the normal link after using the standby link comprises, in parallel with transmission on the standby link, preliminary verification of the continuity of the normal link. The preliminary verification involves simultaneous transmission of a data signal by the terminal equipment initiating the continuity verification procedure, on the normal link and on the standby link, and detection by the other terminal equipment of the presence or absence of power on the normal link. This is done for each transmission medium of the normal link if the latter comprises separate media for each transmission direction.
