IMAGE COMMUNICATION APPARATUS CAPABLE OF PERFORMING FACSIMILE COMMUNICATION VIA IP NETWORK, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM

摘要

The present invention provides a technique that enables an image communication apparatus capable of performing voice communication and T.30 in-band FAX communication over the IP network to positively detect a CNG signal and achieve switching to FAX reception in the answerphone connection mode and the FAX/TEL-switching mode. The communication apparatus includes a MODEM that controls facsimile communication and a SLIC that controls a telephone. A selector includes switches for connecting the IP network and the MODEM, and switches for connecting the IP network and the SLIC. A CPU controls the switches of the selector such that signals from the IP network are supplied to both of the MODEM and the SLIC.

主权项

1. A communication apparatus that is capable of executing facsimile communication via an IP network, the communication apparatus comprising:
a facsimile controller including a tone detector configured to detect a CNG signal, and configured to control facsimile communication; a telephone controller configured to control a telephone; a selector configured to control whether to supply input signals from the IP network to both the facsimile controller and the telephone controller, or to either the facsimile controller or the telephone controller; and a setting unit configured to set a reception mode of the communication apparatus from among a plurality of reception modes including a FAX/TEL-switching mode that, when a call is received, automatically determines whether to execute a facsimile reception or execute voice communication using the telephone, wherein the selector provides control so that the input signals from the IP network are supplied to the facsimile controller and are prevented from being supplied to the telephone controller according to a call for voice communication being received when the FAX/TEL-switching mode has been set by the setting unit, and wherein the facsimile controller executes the facsimile communication via the IP network according to the tone detector detecting the CNG signal.
