Abstract
In a data communication apparatus, when performing a calling operation, an image transmission speed is assigned using a CCITT nonstandard reception command NSS after transmitting a dial signal, and the NSS is repeatedly transmitted at a predetermined time interval. Upon reception of a reception-preparation-confirming signal transmitted from an apparatus of a communication partner, a command, an identification signal and image data are transmitted at the image transmission speed based on information relating to the communication partner's apparatus which has been stored, so that the time required for communication procedures is shortened.
