Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling a facsimile machine which is connected to a dial-in line and executes a facsimile reception operation or a telephone reception operation according to an extension designation number received when a call is detected.

[0002]

2. Description of the Related Art In recent years, with the spread of facsimile machines, it has become necessary to share one telephone line between a telephone and a facsimile machine. In this way, when one telephone line is shared by a telephone and a facsimile machine, when an incoming call is detected and it is not known whether it is an incoming call to the telephone or an incoming call to the facsimile machine, an appropriate facsimile reception operation or call operation is performed. A situation occurs in which the

As one method for solving such a situation, for example, if a facsimile calling signal (calling tone CNG; transmission procedure signal of old CCITT Recommendation T.30) can be received within a predetermined time when an incoming call is detected, the other party If it is determined that the terminal (calling terminal) is a facsimile machine, and thereafter, a facsimile incoming call operation is performed and if the calling tone CNG cannot be detected within a predetermined time after the incoming call is detected, the other terminal is a telephone. It is conceivable to make a judgment and perform an operator's calling operation (for example, repeatedly ringing a ringing sound).

In addition, a dial-in service is provided to one telephone line (hereinafter, such a telephone line is referred to as a dial-in line), and a dial-in number for receiving a facsimile and a dial-in number for receiving a telephone are set. When an incoming call is detected, a predetermined dial-in operation is performed, and when a dial-in number for receiving a facsimile is notified as an extension specified number, a facsimile receiving operation is performed and a dial-in number for receiving a telephone is notified as an extension specified number. When it is called, the one that calls the operator is also in practical use.

FIG. 9 shows an example of a procedure at the time of dial-in connection (subscriber switch side). In this case, the terminal side is a facsimile machine.

First, when calling a dial-in subscriber, the subscriber line exchange first reverses the polarities of the office lines L1 and L2, and sends out a ringing tone after about 0.1 seconds.

Next, the subscriber exchange is connected to the central office lines L1 and L2.
When the primary response signal (DC loop formation) is received within 6 seconds after the polarity reversal of (when the signal does not arrive during this time, the subscriber exchange starts disconnection operation), the extension specified number ( Push button signal: 1 to 4 digits) is transmitted.

Then, the subscriber exchange receives the extension designation reception completion signal (DC loop disconnection) within approximately 0.3 seconds to a maximum of 2.1 seconds after the transmission of the extension designation number is completed (the signal is not received during this time). If it arrives, the subscriber exchange enters the disconnection operation), and then enters the secondary response signal waiting state after about 0.3 seconds.

Upon receiving the secondary response signal (DC loop formation), the subscriber exchange repolarizes the polarities of the office lines L1 and L2 to form a communication path.

When the DC loop is disconnected, the communication ends.

When a facsimile machine connected to the dial-in line receives an incoming call while the facsimile receiving operation cannot be performed due to, for example, a recording paper shortage or a memory exhaustion. The conventional device performs one of the following two operations.

[0012] One of them is an operation of turning off the silent incoming call (thus, the telephone rings at the time of incoming call) and controlling not to form a DC loop with respect to the ringing signal.

The other is to perform a primary response operation to a calling signal, receive an extension designated number, and if the extension designated number is an extension number for receiving a facsimile, the subsequent processing is performed. Is not executed (therefore, the subscriber exchange executes the disconnection operation).

[0014]

However, such a conventional apparatus has the following disadvantages.

First, in the former device, when the dial-in line connection procedure is not executed when the extension designated number for receiving a telephone call is received, it is impossible to communicate with the telephone set of the own station. Occurs.

Further, the latter device has a disadvantage that it cannot notify the user on the terminal side that the facsimile device is in a state in which it cannot receive an incoming call.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a method for controlling a facsimile machine which can effectively utilize a dial-in line.

[0018]

According to the present invention, there is provided a method for controlling a facsimile machine, which is connected to a dial-in line and executes a facsimile receiving operation or a telephone receiving operation according to an extension designation number received when a call is detected. When the extension designation number received at the time of detection is a value corresponding to the facsimile reception operation, it is checked whether the facsimile reception operation can be performed. If the facsimile reception operation cannot be performed, the operator calling operation is performed. When a facsimile reception operation can be performed, a predetermined facsimile reception operation is performed.

Further, in the control method of the facsimile apparatus which connects to the dial-in line and executes the facsimile receiving operation or the telephone receiving operation in accordance with the extension designation number received when the call is detected, the extension designation number received when the incoming call is detected is detected. When the value corresponds to the facsimile receiving operation, it is checked whether or not the facsimile receiving operation can be performed. If the facsimile receiving operation cannot be performed, the first operator calling operation is performed and the facsimile receiving operation can be performed. In this case, while performing a predetermined facsimile reception operation, when the extension designation number received at the time of incoming call detection corresponds to the telephone reception operation, the second operator calling operation is performed, and the first operator calling operation is performed. First operator calling time of the second operator and the second operator during the second operator calling operation Call time is obtained by setting to different values.

Also, the first operator calling time,
The second operator calling time can be set to an appropriate value.

Further, in the control method of the facsimile apparatus which is connected to the dial-in line and executes the facsimile receiving operation or the telephone receiving operation according to the extension designation number received at the time of detecting the call, a predetermined dial-in line is detected at the time of detecting the incoming call. If the procedure signal cannot be received, the incoming operation is performed when the non-dial-in line is connected, while if the predetermined dial-in line procedure signal is received when the incoming call is detected
When the received extension designation number has a value corresponding to the facsimile receiving operation, it is checked whether or not the facsimile receiving operation can be performed. If the facsimile receiving operation cannot be performed, the operator calling operation is performed while the facsimile calling operation is performed. When the receiving operation can be performed, a predetermined facsimile receiving operation is performed.

[0022]

Therefore, regardless of whether or not the facsimile reception operation can be performed, the dial-in line connection procedure is appropriately performed. Therefore, when the telephone extension number is received, the operator is called without fail, and as a result, the telephone is connected. You can make appropriate calls. When the facsimile reception operation cannot be performed, the operator is called, and the user who answers the telephone hears the signal from the facsimile apparatus, so that the call is received by the facsimile apparatus. It is possible to know the situation in which no response can be made, and it is possible to perform work such as inspecting the state of the facsimile device of the terminal itself, and as a result, the usability of the facsimile device is improved.

Further, since the operator call time when the facsimile reception operation cannot be performed and the operator call time when the telephone extension designation number is received are set to different values, the operator calling mode in each state is set. It can be different, and appropriate operation is possible.

Further, when a dial-in line procedure signal cannot be received within a predetermined time when a call is detected, an incoming call operation is performed when a non-dial-in line connection is made. For example, the dial-in service is activated from the contract of the dial-in service. An appropriate incoming call operation can be performed during the period up to the time.

FIG. 3 shows an example of processing when a call signal of 16 Hz is transmitted from the subscriber exchange and an incoming call is detected.

First, the detection of a call signal of 16 Hz is monitored (NO loop of decision 101). When the call signal is detected and the result of decision 101 is YES, the above primary response signal is sent out. The operation (primary response operation) is performed (process 102), the operation of receiving the extension designation number sent from the subscriber exchange is started (processing 103), and the process waits until reception of any extension designation number is completed (determination). 104 NO loop).

If any of the extension designation numbers is received and the result of the determination 104 is YES, the above-mentioned predetermined extension designation reception completion signal is sent (process 105), and the extension designation number received at that time is It is checked whether it is the telephone extension number (decision 106). The result of judgment 106 is Y

Starts the ringing operation of the telephone 11.

Then, it is monitored whether the user picks up the handset of the telephone 11 and goes off-hook before the timer TM times out (decisions 303, 3).
04 NO loop).

The user does not respond to the ringing of the telephone 11,
When the result of determination 305 becomes YES when the timer TM has timed out, the operator calling operation for the telephone 11 by the network control device 10 is terminated (Process 3
05), the operator calling process A is terminated.

When the user picks up the handset in response to the ringing of the telephone set 11 before the timer TM times out and the result of the decision 303 is YES, the network control device 10 sends the telephone set 11 to the telephone set 11. The operator calling operation is ended (process 306), the above-described secondary response operation is performed (process 307), and the user waits until the user ends the call, returns the handset, and goes on-hook (NO loop of decision 308). The user returns the handset, goes on hook, and when the result of determination 308 is YES, the operator calling process A is terminated.

In this way, in this embodiment, when a ringing signal is detected, the dial-in line connection procedure is once executed to receive the extension designation number, and the received extension designation number is the telephone extension number. Since the operator calling operation is performed, the dial-in connection to the telephone is possible regardless of the state of the facsimile device, and the usability of the facsimile device is improved.

If the designated extension number is a facsimile extension number and the facsimile device cannot perform the receiving operation, the operator is called to hear the tone signal transmitted from the facsimile device on the partner terminal side. ing. As a result, the user knows that this incoming call is related to the calling request from the facsimile machine, and recognizes that there is a reception failure in the facsimile machine of the own terminal and the incoming call cannot be answered. Therefore, it is possible to perform work for removing the cause of the reception failure.

Since the time for calling the operator when the telephone extension number is received and the time for calling the operator when the facsimile extension number is received but cannot be received are set to different times, each operator calling time is set. Can be set to an appropriate value, and the usability of the facsimile apparatus is improved. In this case, the former ringing time can be set to a general time in which the calling user can repeatedly listen to the ringing tone and hold off-hook (for example, a period of time during which the ringing tone rings 10 times). , The latter calling time is the time to wait until the transmission procedure signal is received from the partner terminal after the facsimile device of automatic transmission detects the off-hook of the partner terminal (for example, the repeating sending operation of the calling tone CNG is performed about three times). Time to execute).

FIG. 6 shows another processing example when a call signal of 16 Hz is transmitted from the subscriber exchange and an incoming call is detected.

First, the detection of the call signal of 16 Hz is monitored (NO loop of decision 401). When the call signal is detected and the result of decision 401 is YES, the above primary response signal is sent out. The operation (primary response operation) is performed (process 402), the operation of receiving the extension designation number sent from the subscriber exchange is started (process 403), and a predetermined time (for example, about 8 seconds = (6 + 0.6 + ( It is monitored whether or not the reception of any extension designation number is completed before the lapse of (the maximum value of extension designation number transmission time)) (NO loop of decisions 404 and 405).

When the predetermined time elapses without receiving the extension designation number and the result of judgment 404 is YES, at that time, the internal state of the own terminal is checked to determine whether the reception operation can be performed. Examine (decision 406).

When the result of the judgment 406 is YES, the facsimile reception procedure is executed when the calling tone CNG is detected, and the CNG detection switching facsimile reception processing is executed to perform the call operation when the calling tone CNG is not detected (process 407). ), End the operation at the time of this incoming call.

Further, for example, when the recording paper is out of the plotter 5 or the image storage device 8 is in a memory full state, it is a case where the facsimile receiving operation cannot be properly performed, and the determination 406 is made. When the result is NO, a predetermined operator calling process B (process 408)
Then, the operator is called to notify the operator of the state of the terminal itself, and the operation upon receipt of the call is terminated.

When any of the extension designation numbers is received and the result of the determination 405 is YES, the above-mentioned predetermined extension designation reception completion signal is transmitted (process 409), and the extension designation number received at that time is determined. It is checked whether it is the telephone extension number (decision 410). The result of judgment 410 is Y
When it becomes ES, a predetermined telephone reception process (process 41
1) is executed to end the operation at the time of this incoming call.

If the received extension designation number is a facsimile extension number and the result of decision 410 is NO, then at that time, the internal state of the terminal itself is examined to see if the receiving operation can be performed (decision). 412).

When the result of determination 412 is YES, the above-described secondary response operation is performed (process 413), a predetermined facsimile reception process (process 414) is executed, and the operation at the time of incoming call is terminated.

The user returns the handset, goes on hook, and when the result of determination 607 is YES, the operator calling process B is ended.

In this way, in this embodiment, when the extension designation number cannot be detected within the predetermined time after the incoming call is detected, it is determined that the dial-in line is not established, and the non-dial-in line is connected. Therefore, the appropriate incoming call operation can be performed during the period from the dial-in service contract to the dial-in service being effective, for example.

In the above-described embodiment, when the facsimile device cannot perform the receiving operation, the user is made to hear the signal transmitted from the facsimile device of the partner terminal, so that the facsimile device of the own terminal receives a reception failure. However, for example, the facsimile device is provided with means for transmitting a voice message indicating that a reception failure has occurred, and the handset of the telephone is set in response to the ringing of the ringing tone. By sending the above voice message to the picked-up user, it is possible to notify the facsimile apparatus of the own terminal that the reception failure has occurred. In this case, the voice message can be sent from an external speaker or the like. In this case, the connection procedure processing for the subscriber exchange after the secondary response is not performed.

Further, in the above-described embodiment, the operator calling time (phone receiving ringing time, facsimile receiving ringing time) is set, but the ringing number of times of ringing for operator calling is set. , Produces the same effect.

Further, in the above-described embodiment, the case where the polarity reversal due to the on-hook of the calling side cannot be detected after the extension designation number reception completion signal is transmitted has been described. However, even when such a phenomenon can be detected, the present invention is similarly applied. can do.

[0080]

As described above, according to the present invention,
The dial-in line connection procedure is properly performed regardless of whether or not the facsimile reception operation can be performed. Therefore, when the extension number for the telephone is received, the operator is always called, and as a result, the telephone call by the telephone is properly performed. Get the effect that you can. If the facsimile reception operation cannot be performed, the operator is called, and the user who answers the telephone hears the signal from the facsimile apparatus, so the incoming call is to the facsimile apparatus. It is possible to know the situation in which no response can be made, and it is possible to perform an operation such as inspecting the state of the facsimile device of the terminal itself. As a result, the usability of the facsimile device is improved.

Since the operator call time when the facsimile reception operation cannot be performed and the operator call time when the telephone extension designation number is received are set to different values, the operator calling mode in each state is set. There is also the effect that they can be made different and appropriate operation is possible.

When a dial-in line procedure signal is not received within a predetermined time when a call is detected, the incoming operation is performed when the non-dial-in line is connected. For example, the dial-in service is activated from the contract of the dial-in service. There is also an effect that an appropriate incoming call operation can be performed in the period until the time.
