Abstract: PURPOSE:To simplify a processing at a receiving side and to reduce errors in a procedure by providing a means to transmit a signal to identify whether an error re-sending is continued or next frame data are transmitted, and informing an error re-sending frequency. CONSTITUTION:The title device has a means to re-transmit in the frame data indicated from an opponent destination based on a transmitting request from the opponent destination when the data are transmitted by dividing them into plural frames, a means to count the re-sending frequency of the same frame by means of the re-transmitting means, and a means to transmit the signal for identifying whether the error re-sending is continued or the next frame data are transmitted when the counting value of the counting means goes to a prescribed value, and the opponent destination is informed of the frequency of the error re-sending. Consequently, after an error frame is detected and a PPR(partial page request) signal is sent, a receiver can identify whether the high-speed data of the re-sending arrive or a low-speed procedure signal arrives. For such a reason, the high-speed data and low-speed data are not necessary to be made simultaneous, and the errors in the procedure can be remarkably reduced.
