PURPOSE:To guarantee mutual connectability without being affected by phase difference at the time of bulk connection by executing a connecting procedure based on BAS reception interruption and controlling the demultiplex processing of received data after the absorption of phase difference. CONSTITUTION:The received data of one channel are distributed to the other channels by a selector 19, and a data receiving state can be provided at all times. Synchronizing monitoring circuits 11 and 13 reads a multiframe number, frame number and BAS and output a frame timing signal. Read timing generating means 15 and 16 detect the phase difference of received data between channels, generate a read timing signal, correct that read timing signal and generate BAS reception interruption synchronously with this signal. On the other hand, the received data absorbing the phase difference are outputted from the received data storage means 12 and 14. Then, a CPU 21 executes the connecting procedure by using the BAS after the absorption of phase difference based on the BAS reception interruption and controls the demultiplex processing of received data. |
