PURPOSE:To enable the two reception signals to share the same decoder and the synchronizing device by switching the reception signal selection device with the transmission timing signal of the reception signal of one side to change the reception signal from one side to another. CONSTITUTION:Reception signal A is selected through reception signal selection device 6 and receives the bit set-up via bit synchronizing device 4 after decoding 3 to be given data decording 8. While the starting signal sent from reception signal B is identified by starting signal decoder 7, and the reception mode control signal 9 of the output sets devices 6 and 8 to the selection and decoding modes of signal B. Then signal B is selected through device 6 and receives the synchronous set-up by bit synchronizing device 4 after decoding 3 to be given data decoding 8. As a result, the two reception signals can share the same decoder and sychronizing device. |
