JPH0946501A - Device for notifying erroneous termination of facsimile document - Google Patents

Abstract

PROBLEM TO BE SOLVED: To allow a sender to cope quickly with the occurrence of erroneous- termination of a facsimile document by notifying the occurrence of mis-arrival of the facsimile document to the sender when the facsimile document is sent in mistake to an extension telephone set. SOLUTION: When a modem (FAX) signal is received from a FAX 14 by a PBX 1 through an electric communication network 10, a modem signal detection section 2b informs it to a CPU 7 and the CPU 7 discriminates whether a destination of the received signal is an extension telephone set 12 or an extension facsimile equipment 13 based on a received number in the received signal. In the case of the arrival of the signal to the extension telephone set 12. The PBX 1 informs a message of 'mis-arrival' stored in a character storage section 6 to the opposite FAX 14 in terms of FAX signals. Or the message of 'mis- arrival' may be informed to the opposite FAX 14 in voice from a voice storage section in place of the FAX signals.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for notifying a caller that an incoming call has been received by a FAX (facsimile) call from an extension telephone connected to a PBX.

[0002]

2. Description of the Related Art A conventional FAX false call notification device will be described with reference to the block diagram shown in FIG.

In FIG. 3, when the FAX 14 erroneously receives an incoming call at the telephone 12 connected to the PBX 1, or when an attempt is made to reach the FAX 13 in the unreceivable state (busy: busy), communication is not possible due to protocol mismatch or busy. Since it is not possible, the FAX 14 judges that there is a communication error and outputs a communication error notification to the sender by itself.

[0004]

However, in the conventional error notification device as described above, is the sender's terminal being FAX and busy, or is the caller hanging up on the telephone due to incorrect numbering? I don't know.

The present invention solves the above-mentioned problems of the prior art. When a fax call is received by an extension telephone, the caller is receiving the call, that is, an erroneous call due to an incorrect numbering. It is an object of the present invention to provide a FAX false call notification device capable of notifying that there is something, and therefore capable of promptly performing FAX communication.

[0006]

According to the technical means of the present invention for achieving the above object, when an extension telephone connected to a PBX receives a FAX call from the outside, it is notified from a telecommunication network. It is characterized in that the FAX caller is notified of an erroneous incoming call by a FAX signal based on the caller number information.

[0007] Another technical means of the present invention for achieving the above object is to provide caller ID information notified from the telecommunications network when an extension telephone connected to the PBX receives a FAX call from the outside. Based on the above, it is characterized in that the FAX caller is notified of an erroneous incoming call by the voice data accumulated in advance.

[0008]

Therefore, according to the present invention, when a fax is erroneously transmitted to the extension telephone connected to the PBX, the caller can know that the call is erroneous due to the erroneous call notification.

【Example】

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the FA according to the first embodiment of the present invention.
X PBX, extension telephone, FA using false call notification device
FIG. 4 is a block diagram of a related configuration of a fax incoming to an X, a telecommunication network, and a PBX.

In FIG. 1, reference numeral 1 is a PBX, which is composed of a station line unit (card) 2, an extension unit (card) 3, a time division time switch 4 for exchanging data, a character storage section 6 and a CPU 7 for controlling these. Has been done. In the character storage unit 6, not only a message indicating an erroneous call, but also an accurate FAX number and the like are stored. The control signal from the CPU 7 and the detection signal to the CPU 7 are notified by the data bus 8, and the voice data and the like are notified by the PCM highway 9.

Within the station line unit 2, a calling number detector 2a for detecting the calling number 11 notified from the telecommunication network 10 and notifying the CPU 7, and a modem (MO) for recognizing the FAX signal.
DEM) signal (FAX signal) detector 2b and network-PB
It has an X interface 2c.

Reference numeral 12 is an extension telephone connected to the extension unit 3 of the PBX 1, 13 is an extension FAX connected to the extension unit 3 of the PBX 1, and 14 is a FAX connected to the telecommunication network 10.

In the above structure, the FAX 14 is a PBX.
When making a call to the extension telephone 12 connected to 1, the telecommunications network 10 adds the calling number 11 of the FAX 14 and PB
Notify X1 of the incoming call to the extension telephone set 12. PBX1
The calling party number 11 received from the telecommunication network 10 is detected by the calling party number detecting section 2a and notified to the CPU 7. Next, when the signal from the telecommunication network 10 is a modem signal (FAX signal), the modem signal detection unit 2b detects the modem signal and notifies the CPU 7 of it. The CPU 7 recognizes who is the called party from the FAX 14 (whether it is the extension telephone 12 or the extension FAX 13), and when it is the extension telephone 12 other than the extension FAX 13, it is stored in the character storage unit 6. The message is transmitted as a modem signal from the station line unit 2 to the FAX 14 via the telecommunication network 10. As described above, according to the first embodiment, when the FAX 14 erroneously receives an incoming call to the extension telephone 12, Based on the calling number 11 notified from the communication network 10, the F
An erroneous incoming call can be notified as an AX signal. (Embodiment 2) Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 2 shows the FA according to the second embodiment of the present invention.
X PBX, extension telephone, FA using false call notification device
FIG. 4 is a block diagram of a related configuration of a fax incoming to an X, a telecommunication network, and a PBX.

In the present embodiment, the same parts as those in the first embodiment will be designated by the same reference numerals and the description thereof will be omitted, and a different structure will be described.

The feature of this embodiment is that, as shown in FIG. 2, in place of the character storage unit 6 in the first embodiment, an accurate FAX number and the like are stored in addition to a message indicating an erroneous incoming call. The voice storage unit 5 is connected to the time division time switch 4 by the PCM highway 9.

In the above structure, the FAX 14 is a PBX.
When making a call to the extension telephone 12 connected to 1, the telecommunications network 10 adds the calling number 11 of the FAX 14 and PB
Notify X1 of the incoming call to the extension telephone set 12. PBX1
The calling party number 11 received from the telecommunication network 10 is detected by the calling party number detecting section 2a and notified to the CPU 7. Next, when the signal from the telecommunication network 10 is a modem signal (FAX signal), the modem signal detection unit 2b detects the modem signal and notifies the CPU 7 of it. The CPU 7 determines who is the called party from the FAX 14 (whether it is the extension telephone 12 or not).
If it is an extension telephone 13 other than the extension FAX 13, the message accumulated in the character accumulating unit 5 is used as a voice signal from the station line unit 2 via the telecommunication network 10 to the FAX 14. As described above, according to the second embodiment, when an erroneous call is received from the FAX 14 to the extension telephone 12, the voice data is sent to the calling FAX 14 based on the calling number 11 notified from the telecommunication network 10. As, it is possible to notify an erroneous call.
