Abstract
When facsimile data is transmitted by performing facsimile communication, a public line is seized. Then, when the public line is seized, it is a determined which of a dial tone signal or a voice signal for phone call a signal received from the public line is, it is controlled to perform the facsimile communication in a case where the received signal is determined as the dial tone signal, and it is controlled not to perform the facsimile communication in a case where the received signal is determined as the voice signal.
Claims19
A facsimile apparatus comprising:
- a communication unit configured to perform facsimile communication;
- a line seizing unit configured to seize a public line in order to transmit facsimile data by the facsimile communication;
- a determining unit configured to determine, in a case where said line seizing unit has seized the public line in order to transmit the facsimile data by the facsimile communication, which of a dial tone signal or a voice signal for a phone call a signal received from the public line is;
- and
- a control unit configured to control said communication unit to perform the facsimile communication in a case where the received signal is determined as the dial tone signal, and not to perform the facsimile communication in a case where the received signal is determined as the voice signal.
A control method for a facsimile apparatus, comprising the steps of:
- performing facsimile communication;
- seizing a public line in order to transmit facsimile data by the facsimile communication;
- determining, in a case where the public line was seized in said line seizing step in order to transmit the facsimile data by the facsimile communication, which of a dial tone signal or a voice signal for a phone call a signal received from the public line is;
- and
- controlling said communication step to perform the facsimile communication in a case where the received signal is determined as the dial tone signal, and not to perform the facsimile communication in a case where the received signal is determined as the voice signal.
A non-transitory computer-readable storage medium which stores therein a program for causing a computer to perform a control method for a facsimile apparatus, the method comprising the steps of:
- performing facsimile communication;
- seizing a public line in order to transmit facsimile data by the facsimile communication;
- determining, in a case where the public line was seized in said line seizing step in order to transmit the facsimile data by the facsimile communication, which of a dial tone signal or a voice signal for a phone call a signal received from the public line is;
- and
- controlling said communication step to perform the facsimile communication in a case where the received signal is determined as the dial tone signal, and not to perform the facsimile communication in a case where the received signal is determined as the voice signal.
