    Abstract: A method for ensuring reliable transmission of a DCN signal by a gateway is disclosed. When acting as a sending gateway, the gateway packs a DCN signal detected into an IFP packet and sends the IFP packet to the IP side, then, reports a fax end event to a Soft Switch after a designated delay period; and the Soft Switch issues a State Switching Command for switching the two gateways back to voice state after receiving the fax end event. When acting as a receiving gateway, the gateway modulates a DCN signal detected and sends the modulated DCN signal to a receiving facsimile machine; if a switching command issued by a Soft Switch is received during sending the DCN signal, the gateway delays the switching; if the gateway has not received a switching command after the DCN data is sent, the gateway initiatively reports a fax end event.

    Abstract: Disclosed is an Internet FAX apparatus which, after receiving an Internet address from a certain destination, can communicate with the same destination in later transmission or during communication by connecting to a LAN and switching to an Internet FAX mode requiring no communication charge. An Internet facsimile apparatus on the receiving side transmits its Internet facsimile function and Internet address on an NSF signal in a standard protocol of G3 facsimile transmission and/or transmits its telephone number, Internet facsimile function, and Internet address on TSI and NSS signals in the standard protocol of G3 facsimile communication. The Internet facsimile apparatus registers an Internet facsimile function and Internet address of a partner apparatus as destination data. The Internet facsimile apparatus communicates with the partner apparatus by using the Internet address in the destination data in later transmission or by disconnecting ordinary facsimile mode communication and switching to the Internet FAX mode.
