Abstract
In a versatile communication device having a telephone function and a facsimile function, an erroneous detection of an on-hold melody as a control signal, such as a calling tone (CNG) signal, is prevented when the on-hold melody is played during an on-hold period of the telephone, thereby preventing the device from mistakenly switching connection to the facsimile function during the on-hold period. Further, the on-hold melody containing a signal component of the CNG signal or other control signal is prevented from sending to the remote device, so the remote device provided with a facsimile function does not switch to a facsimile mode during the on-hold status of the voice communication.
Claims11
A communication device comprising:
- a telephone section for a voice communication with a remote telephone device, said telephone section including an on-hold key for entering an instruction to place said telephone section in an on-hold status;
- a facsimile section for transmitting and receiving facsimile data to and from a remote facsimile device;
- discriminating means for discriminating a predetermined signal received through the line;
- determining means for determining whether or not the voice communication established between said telephone section and the remote telephone device is being in the on-hold status;
- and
- disabling means for disabling said discriminating means when said determining means determines that the voice communication established therebetween is in the on-hold status.
A communication device comprising:
- a telephone section for a voice communication with a remote telephone device, said telephone section including an on-hold key for entering an instruction to place said telephone section in an on-hold status;
- a facsimile section for transmitting and receiving facsimile data to and from a remote facsimile device;
- discriminating means for discriminating a predetermined signal received through the line;
- indication signal generating means for generating a predetermined indication signal indicative of the on-hold status;
- determining means for determining whether or not the voice communication established between said telephone section and the remote telephone device is being in the on-hold status;
- and
- control means for controlling said discriminating means so that said discriminating means discriminates the predetermined signal while canceling a signal component of the predetermined indication signal from the predetermined signal when said determining means determines that the voice communication established therebetween is in the on-hold status.
