Abstract

PURPOSE:To prevent the function deterioration of a system due to disconnection of a transmission line by constituting the transmission line into a double-loop system, and separating a column time decoder output into two frames, to feed terminal equipments connected to the transmission lines respectively, and sending signals. CONSTITUTION:A signal separated into two frames is sent from a column time decoder CT-D104 to two lines Data 1 and Data 2. For example, the breaking of wire occurs between electronic seat boxes SET112a and SEB11b, and passenger service unit decoders PSUD109b and PSUD109c. Consequently, the CT-D104 receives data from the SEB112b to SEB112n with a frame 1 for the transmission of the synchronizing signal and clock signal of the Data 1 from the terminals 105 and 107 of the CT-D104, which transmits data to PSUDs 109c-109n. Similarly, the CT-D104 send data with regard to the synchronizing signal and clock signal of the Data 2 from the terminals 106 and 108.
