Abstract
Abstract A first ISDN terminal transmits a receipt result information report to a second ISDN terminal via a D-channel after the first ISDN terminal receives a data from the second ISDN terminal. The data comprises image information. The image information is transmitted via a B-channel. The receipt result information report indicates a result of receiving of the image information for confirmation by the second ISDN terminal of the receiving at the first ISDN terminal. The D-channel is used for transmitting predetermined protocol information between the ISDN terminals. The predetermined protocol information includes an identification information. The identification information is used for controlling a connection between the ISDN terminals.
