Reconfiguration control method for a loop-type data network |
摘要 |
This invention discloses a loop-back control method for loop-type data transmission systems in which, when a trouble occurs on both transmission lines of two systems, two stations adjacent to the trouble region return signals toward a control station in response to a command from the control station, thereby to separate the trouble region and continue the operation. According to this invention, when the control station detects the occurrence of a trouble on the transmission lines of the two systems, it sends out a broadcast command to search for the trouble point to the transmission lines of both systems and thereafter a loop-back command is issued so that the stations adjacent to the trouble point can loop-back the transmission.
