Abstract
A recipient communication terminal device, that can communicate in a V.34 communication mode, communicates with a transmitter communication terminal device, that cannot communicate in the V.34 communication mode. The transmitter device detects whether or not the recipient device includes V.8 communication mode capability in accordance with a received digital identification signal (DIS). When the transmitter device detects that the recipient device includes V.8 communication mode capability, the transmitter device generates a silent state for a prescribed period of time as a response to the received DIS, or stands by without responding to the received DIS until a second DIS is received.
Claims20
A communication terminal device comprising:
- means for detecting a presence or an absence of a capability of an ITU recommendation V.8 communication mode in accordance with a received digital identification signal;
- and
- means for generating a silent state for a prescribed period of time as a response to the received digital identification signal when the means for detecting detects the presence of the capability of the V.8 communication mode.
A communication system comprising:
- a recipient communication terminal device that can execute communication in an ITU V.34 communication mode, and
- a transmitter communication terminal device that cannot execute communication in the ITU V.34 communication mode,
- wherein the transmitter communication terminal device comprises:
- means for detecting a presence or an absence of a capability of an ITU recommendation V.8 communication mode in accordance with a received digital identification signal;
- and
- means for controlling to generate a silent state for a prescribed period of time as a response to the received digital identification signal when the means for detecting detects the presence of the capability of the V.8 communication mode in the recipient communication terminal device.
A facsimile communication method comprising:
- making a call to a recipient communication terminal device from a transmitter communication terminal device;
- transmitting a digital identification signal by the recipient communication terminal device;
- responding to the recipient communication terminal device by the transmitter communication terminal device after a prescribed period of silent time;
- and
- transmitting image data to the recipient communication terminal device from the transmitter communication terminal device.
A facsimile communication method comprising:
- receiving a first digital identification signal;
- determining a presence or absence of ITU recommendation V.8 communication mode capability in accordance with the first digital identification signal;
- and
- when the ITU V.8 communication mode capability is present, executing either a first mode or a second mode of operation,
- wherein the first mode of operation comprises generating a silent state for a prescribed period of time, and
- wherein the second mode of operation comprises standing by until a second digital identification signal is received.
A facsimile communication terminal device incapable of communicating in V.34 communication mode, comprising:
- a control unit that detects a presence or absence of V.8 communication mode capability in accordance with a received digital identification signal, and that executes either a first mode or a second mode of operation when V.8 communication mode capability is detected,
- wherein the first mode of operation comprises generating a silent state for a prescribed period of time, and
- wherein the second mode of operation comprises standing by until a second digital identification signal is received.
