Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having a function of ringing a connected telephone when a facsimile signal is not received after receiving a call and capturing a line.

2. Description of the Related Art When an incoming call is received, a transmission control procedure of facsimile communication is started. When a predetermined signal is not received from the other party, the connected telephone is ringed. There is known a facsimile apparatus having a facsimile / telephone automatic switching function of switching and connecting a telephone to a telephone side to make a call state.

By the way, in a general public telephone network, when making a call by telephone, when the telephone is ringed at the destination and a call is started, a ring back tone is returned from the central office.

Therefore, such a facsimile apparatus transmits a ringback tone to the calling side during the ringing of the telephone so as to notify that the calling is being performed.

By the way, specifications such as frequency and transmission timing of various tone signals in a telephone network such as a ringback tone are stipulated by a telecommunications carrier that owns the telephone network, and are internationally unified. Not something.

[Problems to be Solved by the Invention] Therefore, for example, when the above-described facsimile apparatus manufactured in Japanese specifications is used in a foreign country, the ringback tone transmitted from the facsimile apparatus is changed to the ring of the telephone network of the country. It may be different from the back tone. In this case, there is a problem that the calling party cannot determine the meaning of the tone signal, and cannot recognize that the called party is ringing the telephone and calling the operator.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus which can solve the above-mentioned inconvenience and can transmit a correct ring-back tone to a calling side in accordance with the specifications of a public telephone line network which is always used.

[Means for Solving the Problems] For this purpose, the present invention is to record a ringback tone received when a call is originated on the telephone network in use, and after receiving a call and capturing a line, While the facsimile signal is not received and the telephone is ringing, the recorded ringback tone is transmitted to the other party.

[Operation] As a result, a correct ring-back tone according to the specifications of the public telephone line network used can be transmitted to the calling side.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a facsimile apparatus according to an embodiment of the present invention. In the figure, a telephone line and a telephone 2 are connected to the facsimile machine 1.

A facsimile processing unit in the facsimile machine 1
Numeral 11 executes a series of processes for reading a document image and transmitting image information, while recording the received image information on recording paper. The RBT recording unit 12 is for recording a ringback tone received from a telephone line. The A / D (analog / digital) conversion circuit 12a converts a received signal into a digital signal, and a memory 12b stores the digital signal. And D / A to convert stored digital signals to analog signals
(Digital / analog) conversion circuit 12c.

The network control device 13 controls incoming and outgoing call control such as detection of an incoming call from a telephone line and transmission of a selection signal, and switches connection of the telephone line to the telephone 2, the facsimile processing unit 11, and the RBT recording unit 12.

The operation display unit 14 displays the operation state of the device while the operator performs various operations on the device such as designation of a call destination and start operation. The control unit 15 controls the above device and each unit.

When using this facsimile apparatus 1 with the above configuration, first, a ringback tone of the telephone line network to which this apparatus is connected is recorded.

When the facsimile machine 1 is not communicating, the telephone 2 is connected to the telephone line and is in a state where it can be used freely.

FIG. 2 shows a ringback tone recording process. That is, the operator off-hooks the telephone 2 and performs a calling operation to an arbitrary destination (process 101). When the ringing tone is heard from the handset after the calling of the other party is started (Y in process 102), the operation display unit 14 is started.
A recording instruction is issued by a predetermined operation (step 103).

As a result, the ringback tone signal received from the line is input to the RBT recording unit 12. In the RBT recording unit 12, the input signal is converted into a digital signal by the A / D conversion circuit 12a for a predetermined period of time (process 104). The memory 12b stores the converted digital signal (Process 105).

Thereafter, when the destination operator answers, the call is made as necessary, while when the answer is not answered, the telephone 2 is directly off-hook (process 106).

As a result, the ringback tone used in the telephone line network is recorded in the RBT recording unit 12.

FIG. 3 shows the communication processing of the facsimile apparatus 1. First, with the telephone 2 connected to the telephone line (processing 201), an incoming call is monitored (N loop of processing 202).

When an incoming call is detected (Y in process 202), the telephone line is switched to the facsimile processing unit 11 and connected (process 202).
203). Next, the facsimile processing unit 11 responds to the other party by transmitting, for example, a CED signal and a DIS signal, and starts a predetermined transmission control procedure for facsimile communication.
On the other hand, when a predetermined facsimile signal such as a DCS signal is transmitted from the other party (Y in step 204), the transmission control procedure is continued to execute predetermined facsimile communication (step 205). When this communication operation ends, the state returns to the initial state (to processing 201).

By the way, in the above case, when the other party's caller is trying to talk and calling from the telephone, the predetermined facsimile signal is not transmitted.

If the facsimile apparatus 1 does not receive a predetermined facsimile signal even after a certain period of time has passed (N in process 204),
A ringing signal is output to the telephone 2 to cause ringing (processing
206). At the same time, the signal of the ring back tone stored in the memory 12b is read out, and the D / A conversion circuit 12c
To convert to an analog signal. Then, the ringback tone signal converted into the analog signal is transmitted to the destination. After that, the stored signal for a predetermined time is repeatedly and continuously transmitted (process 207).

Next, the hook state of the telephone 2 is started (step 20).
8) In the case of on-hook (N in processing 208), the above processing 20
Return to 6.

Then, when the telephone set 2 is off-hook by the operator (Y in step 208), the ringing of the telephone set 2 is stopped, the transmission of the ring back tone is stopped (step 209), and the state returns to the initial state (step 208). 201).

As a result, the telephone line is switched from the facsimile processing unit 11 to the telephone set 2 and the operator can talk with the caller.

As described above, in this embodiment, the ringback tone used in the telephone network is recorded first, and the signal tone is transmitted, so that the use of the telephone line network which is always used is performed. The correct ringback tone can be sent to the calling party. This allows the caller to correctly know that the called party is calling the operator.

In the above-described embodiment, the ringback tone is converted to a digital signal and the data is stored in the memory. However, the analog signal may be recorded as it is, for example, on a recording tape. Needless to say. In addition, the ringback tone recording operation is started manually, but may be automatically executed.

[Effects of the Invention] As described above, according to the present invention, a ringback tone received when a call is originated through the telephone line network being used is recorded, and the recorded ringback tone is transmitted to the calling party. , So that a correct ringback tone in accordance with the specifications of the public telephone network being used at all times can be transmitted to the calling side.
