Facsimile apparatus
First Claim
1. A facsimile apparatus for facsimile communications over an IP network, comprising:
- a network interface that connects to the IP network via a LAN or a public line;
a TCP/UDP/IP protocol control unit that is connected to the network interface and controls an IP protocol and a TCP/UDP protocol;
a real-time transfer protocol control unit that is connected to the TCP/UDP/IP protocol control unit and controls a real-time transfer protocol;
a voice encoding/decoding unit that is connected to the real-time transfer protocol control unit and encodes and decodes a voice signal;
a facsimile modem that is connected to the voice encoding/decoding unit and modulates and demodulates a facsimile signal;
a first T30 protocol control unit that is connected to the facsimile modem and controls a T.30 facsimile protocol;
a first communication image processing unit that is connected to the first T30 protocol control unit and conducts image processing of communication image data; and
an image storage unit that is connected to the communication image processing unit and stores a read image or image data received from a network;
wherein;
real-time facsimile communications of a virtual voice-mode are conducted with a conventional facsimile apparatus via the IP network.

Abstract
A virtual voice mode facsimile communication unit, comprised of a TCP/UDP/IP control section which controls an IP protocol and a TCP/UDP protocol, a real-time transfer control section which controls a real-time transfer protocol, a voice encoding/decoding section which encodes/decodes a voice signal, a MODEM which modulates/demodulates assuming that a facsimile signal is a voice signal, a T30 control section which controls a T.30 facsimile protocol and a communication image processing section which conducts image processing of communication image data, is provide for real-time facsimile communications with a conventional facsimile apparatus over an IP network in a state kept connected to a LAN via a network I/F.
