JPH08331213A - Automatic fax cut-off telephone set - Google Patents

Abstract

PURPOSE: To prevent an unpleasant communication tone from being heard by discriminating that the incoming call is of a Fax by analyzing the frequency of the communication tone from the opposite party, automatically cutting off communication with the opposite side FAX and outputting a message showing that to a receiver. CONSTITUTION: A call is originated from the opposite side FAX through a telephone line 5. In this case, when the receiver is picked up, the opposite side FAX is connected and the communication tone flows from the opposite side FAX. An analytic part 4 analyzes the frequency of this communication tone, detects the difference from a voice and discriminates a wrong telephone call from the FAX. This analytic part 4 starts a FAX control part 3 and a voice generating part 2. The started FAX control part 3 immediately disconnects the line with the opposite side FAX and the voice generating part 2 outputs the message such as 'this is wrong call from FAX' to a receiver 1.

1 is a block diagram showing one embodiment of the main part of the present invention. In FIG. 1, 1 is a handset, 2 is a voice generation unit, 3 is a FAX control unit, 4 is an analysis unit, and 5 is a telephone line. The operation of the FAX automatic blocking telephone configured as described above will be described. Here, the description of the operation when called from a normal voice telephone is omitted.

A telephone line 5 from a partner FAX (not shown)
Take a call via. Here, when the receiver is picked up, the other party FAX is connected and the communication sound from the other party FAX flows.
