ABSTRACT:
A facsimile apparatus processes a predetermined signal from a second external apparatus by means of correlating a first external apparatus with the 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. The signal is used for the operative connection between the facsimile apparatus and the second external apparatus. According to the present invention, the second external apparatus is prevented from frequently transmitting the predetermined signal to the facsimile apparatus. The present invention is applicable to a facsimile apparatus used for an integrated digital network.
