TRANSMISSION PATH DUPLEX COMMUNICATION SYSTEM AND CONTROL METHOD THEREFOR |
摘要 |
PURPOSE: A transmission path duplex communication system and a control method therefor are provided to prevent data loss generated in case of switching the first path to another path when abnormality is generated in the first path. CONSTITUTION: A channel shelf(200) has a receiving board unit(210) including the first receiving terminal(210A) and the second receiving terminal(210B), for receiving data transmitted from a control shelf(100), and outputting the first and second path cell data and the first and second path enable signals. The channel shelf(200) has a duplex control unit(220) for receiving the first and second path enable signals outputted from the receiving board unit(210), and outputting corresponding duplex enable signals and the first and second path cell data. The channel shelf(200) has a reception master control unit(230) for receiving the first and second path cell data outputted from the duplex control unit(220) and outputting the received data through one path, and a channel board unit(240) for receiving a signal outputted from the reception master control unit(230). |
