Abstract

PROBLEM TO BE SOLVED: To allow termination, specially, even when an origination side can not notify a termination side of the number by changing termination control unless the telephone number of the origination side can be detected. SOLUTION: A registration circuit 26 registers a termination acknowledgement code through a signal line 26a so as to allow termination only when specific information is detected after a call connection is made once when the origination side uses a public telephone in a case wherein the origination side does not notify the termination side of the telephone number, or can not notify the termination side of the number. A registration circuit 30 registers a communication telephone number allowing the termination through a signal line 30a. Further, the registration circuit 32 registers a communication telephone number allowing the termination through a signal line 32a. Then a control circuit 20 is informed of an originating telephone number prior to a call connection and when the telephone number is a telephone number allowing termination, the termination is allowed, but when not or when the origination side selects a number nonnotification mode, the termination is inhibited.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to a facsimile apparatus capable of detecting a calling telephone number prior to call connection.

[0002]

2. Description of the Related Art Conventionally, a Caller in the United States has been used as a facsimile apparatus capable of detecting a calling telephone number prior to call connection (call connection in the sense that charging is started).
Facsimile devices compatible with the ID function have been proposed.

However, the Caller ID in the United States is
There was no notification of the cause when there was no notification of the calling phone number, only the notification of the calling phone number.

[0004]

Therefore, the same control is performed without distinguishing between the case where the calling side cannot send the calling telephone number and the case where the calling side has the number notification function but does not notify the number. It was. For example, in both cases, the call was rejected.

However, in the area where the outgoing telephone number cannot be sent out, rejecting the incoming call without notifying the outgoing telephone number may reject an important incoming call and may lose a business opportunity. There is a major drawback.

It is an object of the present invention to properly perform an incoming operation when a calling side cannot send out a calling telephone number in a facsimile apparatus capable of detecting a calling telephone number prior to call connection.

[0007]

Means for Solving the Problems The first invention of the present application is:
In a facsimile device capable of detecting a calling telephone number prior to call connection, a detecting means for detecting that the calling side has selected no number notification prior to call connection, and that the calling side is from a public telephone prior to call connection Has a detecting means for detecting the number, a detecting means for detecting that the calling side cannot notify the number prior to the call connection, and a registering means for registering a telephone number that permits the incoming call. When notified, if the telephone number is a telephone number that allows incoming calls, accept the incoming call, and if the telephone number is not a telephone number that allows incoming calls, or if the caller side does not notify the number prior to call connection. If selected, incoming calls are prohibited.

A second invention of the present application is that, when it is detected that the calling side is a public telephone before the call connection,
Alternatively, when the calling side detects that the number cannot be notified, the incoming call is permitted.

By these, even if the telephone number of the calling side cannot be detected, the incoming control is changed for that reason, and especially when the calling side cannot notify the number, the incoming call can be permitted and an effective operation can be obtained. .

The third invention of the present application is that, when it is detected that the calling side is a public telephone before the call connection,
Alternatively, when the calling side detects that the number cannot be notified, the call is connected once, and when the predetermined information is detected, the subsequent incoming call is permitted. As a result, when the calling side cannot notify the number or the calling party cannot notify the telephone number of the calling side, the incoming call can be permitted if the password can be input thereafter.

The fourth invention of the present application is that, when it is detected that the calling side is a public telephone before the call connection,
Alternatively, when the calling side detects that the number cannot be notified, there are three modes: a mode for permitting the incoming call, a mode for prohibiting the incoming call, and a mode for permitting subsequent incoming calls when the call is once connected and predetermined information is detected. It is characterized in that it has a selecting means for selecting one mode from the two modes and executes an operation in accordance with the selected mode. This makes it possible to select the control when the telephone number of the calling side is not notified, according to the user's preference.

Further, in the fifth invention of the present application, a telephone number for which an incoming call is permitted is separately registered for communication and communication, and if the originating telephone number is for communication, an operator is called,
If the calling telephone number is for communication, facsimile communication is performed. Further, the sixth invention of the present application is characterized in that, prior to the call connection, when it is detected that the calling side is from a public telephone, it is judged as a call and an operator is called. As a result, the incoming call from the public telephone can be effectively achieved in conformity with the fact that there are many calling purposes.

FIG. 1 is a block diagram showing the configuration of a facsimile apparatus according to one embodiment of the present invention.

An NCU (network control unit) 2 connects to a terminal of the line in order to use the telephone network for data communication and the like.
It controls the connection of the telephone exchange network, switches to the data communication path, and holds the loop. In addition, the NCU 2 receives signals from the control circuit 20 (signal lines 20
If a) is "0", the telephone line 2a is connected to the telephone side, and if the signal is "1", the telephone line 2a is connected to the facsimile machine side. If the signal is "2", the telephone line 2a is opened. In a normal state, the telephone line 2a is connected to the telephone 4 side.

The hybrid circuit 6 separates the transmission system signal and the reception system signal, sends the transmission signal from the addition circuit 12 to the telephone line 2a via the NCU 2, and receives the signal from the other side via the NCU 2. The signal is sent to the modulator / demodulator 8 via the signal line 6a.

The modulator / demodulator 8 is based on ITU-T Recommendation V. 8,
V. 21, V.I. 27 ter, V.I. 29, V.I. 17, V.I.
It is a modulator / demodulator that performs modulation and demodulation based on 34, and each transmission mode is designated by the signal line 20c. The modulator / demodulator 8 inputs the signal output to the signal line 20b, outputs the modulated data to the signal line 8a, inputs the received signal output to the signal line 6a, and inputs the demodulated data to the signal line 8a.
output to b.

The ANSam sending circuit 10 is a circuit for sending an ANSam signal. When a signal of signal level "1" is output to the signal line 20d, the ANSam sending circuit 10 sends an ANSam signal to the signal line 10a and sends it to the signal line 20d. When the signal of the signal level “0” is being output, no signal is output to the signal line 10a.

The adder circuit 12 inputs the information of the signal line 8a and the information of the signal line 10a, and adds the result of the addition to the signal line 12a.
Output to

The reading circuit 14 outputs the read data to the signal line 14a, and the recording circuit 16 sequentially records the information output to the signal line 20e line by line.

The memory circuit 18 is used to store raw information of read data and encoded information, and to store received information and decoded information.

The demodulation circuit 22 inputs the information of the signal line 6a and outputs the V.V. V.23 which demodulates and outputs the demodulated data to the signal line 22a. 23 demodulation circuit.

The registration circuit 24 is a circuit for registering the telephone number of the calling side which permits the incoming call through the signal line 24a.
In the registration circuit 24, telephone numbers for which incoming calls are permitted are registered without distinction between calls and communications.

In the case where the calling side does not notify the telephone number, the registration circuit 26 permits the incoming call only when the predetermined information is detected after the call is connected once the calling side is a public telephone or the calling side cannot notify the number. In order to do so, this is a circuit for registering this incoming permission code via the signal line 26a.

The selection circuit 28 selects "permit incoming call", "prohibits incoming call", or "connect once call," as an incoming call permission mode when a dial tone is used to make a call from a public telephone or a number cannot be notified. A circuit that selects one mode from the three modes of "permit subsequent incoming calls only when predetermined information is detected" outputs the selected state to the signal line 28a.

The registration circuit 30 is a circuit for registering a telephone number for a call, which allows an incoming call through the signal line 30a.

The registration circuit 32 is a circuit for registering a communication telephone number which permits an incoming call through the signal line 32a.

The control circuit 20 controls the entire facsimile apparatus of this embodiment. Particularly, in this embodiment, the calling telephone number is notified prior to the call connection, and the telephone number permits the incoming call. If it is a telephone number, the incoming call is permitted, and if the telephone number is not a telephone number that allows incoming calls,
Or, when the calling side selects No Number Notify, incoming calls are prohibited. Further, if it is detected that the calling side is a public telephone prior to the call connection, or if the calling side detects that the number cannot be notified, the incoming call is permitted.

2 and 3 are flow charts showing the control flow of the control circuit 20 in the first embodiment of the present invention. In the first embodiment, the circuits 26, 28,
30 and 32 are not used.

In S46, it is judged whether or not the registration of the telephone number for which the incoming call is permitted is selected by the operation unit (not shown). When the registration is selected, the process proceeds to S48 and the outgoing call for permitting the incoming call is made through the signal line 24a. The telephone number of the side is registered in the circuit 48, and if registration is not selected, the process proceeds to S50.

In S50, it is determined whether or not an incoming call is detected. If an incoming call is detected, the process proceeds to S54, and if no incoming call is detected, the process proceeds to S52 and other processes are performed.

Here, when the calling side selects the notification of the telephone number and makes a call (specifically, when the telephone number of the calling circuit is received from the exchange), the process proceeds to S64.
Continue the incoming call operation. When the calling side selects the non-notification of the telephone number and makes the call (specifically, when the signal (P) is received from the exchange), the process proceeds to S62.

If the caller selects "notify" from the public telephone to make a call (specifically, if the (C) signal is received from the exchange), the process proceeds to S64. Furthermore, when the caller cannot notify due to the facility restrictions of the communication carrier (specifically, when the (O) signal is received from the exchange)
Proceeds to S64.

In S62, the signal "0" is output to the signal line 20a, the CML is turned off, that is, the telephone line 2a is connected to the telephone side 2b and the incoming call is rejected. After this,
Return to S42.
