Abstract
A facsimile apparatus ignores or rejects a requirement to connect with a second external apparatus if the facsimile apparatus is communicating with the first external apparatus when the second external apparatus transmits the predetermined signal to the facsimile apparatus. But the facsimile apparatus memorizes the second external apparatus. After the communication with the first external apparatus, the facsimile apparatus asks the second external apparatus to connect therewith in order to transmit image data. According to the present invention, the second external apparatus is prevented from transmitting the predetermined signal more than twice. The present invention is applicable to a facsimile apparatus used for an integrated digital network.
