PROBLEM TO BE SOLVED: To provide a multiple interface panel for improving reliability of multiple data with respect to respective channel data, improving transmission efficiency and attaining remote maintenance. SOLUTION: In a multiple interface panel, parity operation is performed on reception data for each data channel, first parity information is inserted into relevant bits of a multi-frame and on the basis of control of a maintenance control unit, maintenance information is inserted into bits for maintenance in the multi-frame. The first parity information and the maintenance information are separated from a reception frame, parity operation is performed on reception data for each data channel, third parity information is output, and the first and the third parity information are compared. On the basis of the maintenance information of the reception frame, the reception frame is returned to a transmitting side and on the basis of the control of the maintenance control unit, regardless of a comparison result of the returned frame for the reception data of the data channel, the reception data of the reception frame are output to the interface panel of the relevant terminal as they are.
