PURPOSE:To transmit data without giving effect on a normal operation system if a fault takes place in a system by connecting each of transceivers for operating system/standby system data lines and an internal timing transceiver section to the operating system/standby system data bank. CONSTITUTION:The internal line transceiver section 40 is connected to each of the operating system and standby system data lines 21, 22 via the operating system and standby system data line transceivers 41, 42. A timing line control section 50 is connected to the transmission lines 21, 22 via the timing transceivers 43, 44 and the transceivers 40, 41, 42 are controlled in the timing of the control section 50. The operating system and standby system data banks 11, 12 are connected respectively to the transmission lines 21, 22. If a fault takes place in one of the operating or standby systems, the effect given on the standby system or the operating system in normal operation is eliminated to transmit data. |
