Abstract

PURPOSE:To facilitate dialing and to execute dialing processing efficiently by registering a pause time, a specification of a connection enable signal and a connection disable signal, a monitor time and number of times of dialing corresponding to various dial number patterns in advance. CONSTITUTION:When a dial signal is sent in the case of automatic dialing, whether or not a pattern of a dial number is a registered number pattern is discriminated and when the pattern is registered, the transmission of a dial signal is paused tentatively and automatically. Thus, it is not required for the operator to designate a pause on the occasion of a dial number entry, resulting that dialing is facilitated. Moreover, a reception signal is detected from a line while the signal transmission is paused and when a connection enable signal is detected, a succeeding dial signal is immediately sent, and when a connection disable signal is detected, the dialing is immediately stopped. Thus, line control is ensured. Moreover, since a destination line is registered by each number pattern, the dialing method is changed in response to the line in use.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a telephone line connected to
The present invention relates to a communication device that sends a dial signal and sends it to the other party.

[0002]

2. Description of the Related Art For example, in a company having a plurality of business establishments, a private branch exchange network is formed for each business establishment, and the private branch exchange networks are connected to each other by a dedicated line to perform private branch exchange of one business establishment. A telephone line network is often formed so that the extension of the network can directly dial the extension of the private branch exchange network of another office.

Even in such a telephone line network, a facsimile machine is often used. By the way, in the above telephone line network, when making a call from the extension of one office to the extension of another office, the operator first dials a specific number indicating that the call is to another office, and then You would dial the office number and then the extension number of the other party.

When performing this dial operation, depending on the switching network, after inputting the above-mentioned specific number or business office number, the dial operation is temporarily stopped, the response is confirmed from the line network, and a predetermined signal indicating connection is possible. When answered, it may be necessary to perform the next dial operation.

When an operator inputs a destination dial number and starts the operation, a facsimile machine having an automatic transmission function connects to a line and automatically sends out a predetermined dial signal. When using the dialing number, when you enter the dialed number of the other party, you can pause the sending of the dial signal at the desired number position by entering a specific symbol and specifying a pause. ..

[0006]

However, such pause designation may or may not be necessary depending on the destination of the call. Also, the digit position to be specified in the dial number is different even when necessary. For this reason, the operator has to judge whether or not it is necessary to specify a pause at each time of inputting a dial number and specify a pause at a predetermined digit position, which is a troublesome dial operation.

On the other hand, when the transmission of the dial signal is suspended, the signal tone to be confirmed differs depending on the exchange route. However, conventionally, various signals that differ for each exchange path are not detected, and instead, the pause time of dial signal transmission is set to be sufficiently long. Therefore, even if a signal tone indicating that the connection is possible is answered, the next dial signal cannot be sent immediately, and even if the transmission process is delayed or a signal indicating that the connection is impossible is transmitted, the transmission can be immediately stopped. However, there is a problem in that the calling process cannot be efficiently executed.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems, to provide a communication device which facilitates dial operation and can efficiently perform a calling process.

[0009]

To solve this problem, one invention of the present application is to transmit a dial signal when a part of the leading part of various dial numbers and the rest time are registered in advance in association with each other. In addition, every time a part of the registered numbers is transmitted, the signal transmission is suspended for the corresponding suspension time.

Another aspect of the present invention is to register some of the above-mentioned numbers and two types of signal detection conditions in advance, and to register some of the registered numbers when transmitting a dial signal. Each time a message is sent, the signal sending is temporarily stopped, the received signal from the line is detected, and the received signal that matches one of the two types of signal detection conditions corresponding to the sent part number is detected. On the other hand, while the transmission of the dial signal is immediately continued, the transmission is immediately stopped when the reception signal which matches the other of the signal detection conditions is detected.

[0011]

According to the above-mentioned one invention, the operator can easily perform the dial operation because the pause time required for transmitting the dial signal can be provided without specifying the pause when the dial number is input.

Further, according to another aspect of the invention, the dial signal can be immediately continued to be transmitted or the transmission can be stopped in accordance with the response from the line network, so that the transmission process can be efficiently executed.

[0013]

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram of a facsimile apparatus according to an embodiment of the present invention. In the figure, a scanner 1 reads an original image, and a plotter 2 records and outputs a received image. The encoding / decoding unit 3 compresses the image information to be transmitted by various encoding methods, while decoding the received image information to restore the original image information. The system memory 4 stores information registered in advance in the device or temporarily stores various information during communication operation.

The modem 5 sends and receives image information and various procedure signals for transmission control. The modem 5 is provided with a tone signal detection circuit 5a. The tone signal detection circuit 5a detects various tone signals received from the line and can arbitrarily set the frequency of the detection signal and the on / off time of the signal.

The network control device 6 is connected to a telephone 7 and a telephone line, and controls a predetermined line when making or receiving a call. The network control device 6 includes a dial number reading circuit 6
a is provided. The dial number reading circuit 6a reads a dial signal transmitted when a manual call is made by a dial operation of the telephone 7.

The operation display unit 8 is for displaying various information such as the operating state of the apparatus as the operator performs various operations. The system control unit 9 is a microphone computer that controls the above-mentioned units, and the system bus 10 is a signal line through which the above-mentioned units exchange various control signals and data with each other.

With the above configuration, it is assumed that the facsimile apparatus of this embodiment is connected to the extension of one private branch exchange network. In addition, it is assumed that this switching network is capable of calling from an extension line to an outside line or dialing to another private branch exchange network by a predetermined dial operation.

When using this facsimile apparatus, the operator first performs dial condition registration processing.
In this registration process, as shown in FIG.
Various types of information such as pause time, frequency of connectable signal and detection time, frequency of connectable signal and on time and off time, monitoring time and number of calls are registered in association with each other.

The above-mentioned number pattern is a part of the number at the beginning of each dialed number of each calling party. In this example,
"0" is an outside line, "8" is a call to another private branch exchange network,
"832" is a call to one specific private branch exchange network, "00"
081 "is an NCC (New Cmmon Car
The outside line is transmitted via the tier) line, and “0001” indicates the overseas line.

By the way, in the private branch exchange network of the present embodiment, when each dial signal of the above number pattern is transmitted, the exchange network or another exchange network linked to the exchange network executes a predetermined exchange operation. To do. Then, when each switching network becomes ready to receive the next dial signal,
It is designed to respond with a connectable signal. This connectable signal is a so-called dial tone, which is a continuous signal of a constant frequency. Further, when the line to be used is busy and the predetermined switching operation cannot be continued, the connection failure signal is responded. The unconnectable signal is a so-called busy tone, and is an intermittent signal that is turned on and off at a constant frequency and a constant cycle.

The above-mentioned pause time to be registered is a time during which the transmission of the dial signal is temporarily stopped for the above-mentioned exchange operation after the dial signals of the respective number patterns are transmitted. The signal frequency of the connectable signal is the frequency of the signal received from the switching network, and the detection time is the time for detecting the signal. When the connectable signal is not received, "0" is registered in each of the signal frequency and the detection time.

The signal frequency of the unconnectable signal is the frequency of the signal to be received, and the ON time and OFF time respectively indicate the ON / OFF time of the intermittent signal. The monitoring time is a time limit for executing signal detection. The number of outgoing calls is the number of times redialing is repeated when communication with the destination is impossible.

Each of the above information is registered by a known technique.
The registered information is stored and stored in the system memory 4.

Next, the automatic transmission operation of this facsimile will be described.

3 and 4 show this automatic transmission operation. That is, the operator inputs the dial number of the calling party by a predetermined operation of the operation display unit 8 (process 101) and activates the communication operation (process 102).

When the facsimile apparatus is activated, the line is connected (step 103) and the entered dial number is compared with each number registered as a number pattern. In this case, it is first determined whether or not the first digit of the dial number is registered, and if it is not registered, then the first 2 digits are registered.
It is determined whether the dial number is registered while incrementing the number of digits one digit at a time, like the case where it is determined whether the digit is registered (step 104).

If there is a matching registration number at any digit (Y in process 105), the dial signal for the number of digits is transmitted (process 106). Next, various registration information corresponding to the registration number is read (process 107). Then, it waits for the time indicated by the pause time of the registration information (process 108). Further, the frequency and the detection time of the registered connectable signal, the frequency of the unconnectable signal, the on time and the off time are set in the tone signal detection circuit 5a (process 109). As a result, the tone signal detection circuit 5a comes to detect the reception signal of the set condition.

In this state, the received signal from the line is monitored for the period indicated by the monitoring time (process 110, process 1).
Process 11 from N of 10 and process 11 from N of process 111
2. From N in process 112 to process 110).

Now, for example, as shown in FIG.
It is assumed that the dial number "8321234" is input. Of these numbers, "832" is the number of another private branch exchange network, and "1234" is the extension number of the other party.

In this example, the first digit "8" is registered as a number pattern. Therefore, as shown in FIG. 7B, after the dial signal of "8" is first transmitted, it waits for 2 seconds, which is the rest time. Then, a signal that is a connectable signal that is turned on for 1000 seconds or more at 1000 Hz, and a signal that is not connectable at 1200 Hz is 600 ms on and 100 ms.
Monitor for signals that cycle off and on.

When the circuit network completes a predetermined switching operation, a connection enable signal is transmitted from the circuit. The tone signal detection circuit 5a detects the inter-connection signal. When this signal is detected (Y in processing 110), the dial number collating operation is further continued (to processing 104).

In the above example, it is then determined that "832" is registered. In this way, when there is another registration number (Y in process 105), the dial signal for that number is further transmitted (process 106), and the same operation as above is performed according to the registration information (to process 107). This allows
Send a dial signal of "32" and wait for 3 seconds.
A signal which is turned on at 800 Hz for 2 seconds or more and a signal which is turned on and off at a frequency of 800 Hz in a 300 ms cycle are monitored.

When the switching network completes a predetermined switching operation, a connection enable signal is sent from the line. When this connectable signal is detected (Y in process 110), the process returns to the dial number matching operation (process 104) in the same manner as above.

In the case of the above dial number, there is no corresponding registration number. In this case (N of processing 105), the dial signal for the untransmitted portion is transmitted (processing 113). As a result, in the above example, "1234" is transmitted next to call the destination facsimile machine. When the destination facsimile machine responds, predetermined facsimile communication is executed (process 114).

On the other hand, during the signal monitoring period, for example, when there is no free line in the switching network and the line becomes busy, the switching network responds with a connection disable signal. When this connection disable signal is detected (Y in process 111), the line is immediately disconnected (process 115) and the transmission is temporarily stopped.

After that, the number of calls to the destination is counted (process 116) and compared with the registered number of calls (process 117). Then, when the counted number of calls is less than the registered number of calls (N in process 117), the system waits for a certain period of time (process 118) and repeats the above-described calling operation (to process 103). In this way, the calling operation is repeated, and when the number of callings exceeds the registered number (Y in processing 117), the calling processing is stopped.

Further, during the signal monitoring period, it is conceivable that neither the connectable signal nor the connectable signal is not detected due to a malfunction of the facsimile machine or the switching network, for example.
In such a case, when the monitoring period exceeds the registered monitoring time (Y in process 112), the line is disconnected (process 118) and the transmission process is stopped.

Next, the transmission operation by manual operation will be described.

In the case of manual call, the operator uses the telephone 7
Use to dial the destination dial number digit by digit. In this case, dial signals are sequentially sent to the line simultaneously with the dial operation.

The facsimile apparatus, as shown in FIG.
When the operator operates the dial (process 201), the dial number of the dial signal transmitted is read digit by digit (process 202). Then, similar to the process 104 of FIG.
The dialed number is compared with the registered number pattern (process 203). Here, when the number pattern of the dial number is not registered (N in process 204), the reading of the dial signal is repeated (process 201).
What).

On the other hand, when the number pattern of the dialed number is registered (Y in process 204), each registration information corresponding to the number pattern is read (process 205). Then, similarly to the process 109 of FIG. 3, the tone signal detection circuit 5
a is set to a detection state of a predetermined connectable signal and a connectable signal (process 206), and the received signal is monitored for a designated monitoring time (process 207, N in process 207).
Processing 208, processing 209 from processing 208 N, processing 207 from processing 209 N). Here, when the connection enable signal is detected (Y in process 207), the process returns to reading the dial number again (process 201).

When all the dialing operations are completed and the other party responds, the operator activates the communication operation of the facsimile apparatus. When the facsimile device is activated (process 210), it executes predetermined facsimile communication with the destination facsimile device (process 211).

On the other hand, when the connection-disabled signal is detected during the monitoring period of the received signal (Y in step 208), the operation display unit 8 displays that the line is busy (step 21).
2). If neither a connectable signal nor a connectable signal is not detected during the predetermined monitoring period (Y in process 209), an error display is performed (process 213).

As described above, in this embodiment, the pause time, the specification of the connectable signal and the connectable signal, the monitoring time, and the number of calls are registered in advance corresponding to various dial number patterns.

Then, in the case of automatic transmission, when transmitting the dial signal, it is judged whether or not the dial number is a registered number pattern, and if it is the registered number pattern, the dial signal The sending is automatically paused. As a result, the operator does not need to specify a pause when inputting a dial number, unlike the conventional case, and the dial operation becomes easy.

Further, while the transmission of the dial signal is stopped, the received signal is monitored, and when the connection enable signal is detected, the next dial signal is immediately transmitted, so that the line control can be surely performed. At the same time, the pause time is not taken longer than necessary, so that the call can be sent quickly.

Further, when the connection-disabled signal is detected, or when the signal is not detected within the preset monitoring time, the transmission is immediately stopped, so that unnecessary line connection is prevented. ..

Further, since the number of times of calling is registered for each number pattern, for example, the calling method is increased depending on the line used, such as increasing the number of times of re-calling for a destination that is frequently busy. Can be changed.

On the other hand, in the case of manual transmission, the dial number dialed on the telephone 7 is read to determine whether it is a registered number pattern. If it is a registered number pattern, The predetermined connectable signal and the connectable signal are detected. And
When the connection-disabled signal is detected, the fact that the line is busy is displayed. Therefore, the operator can easily determine that the line is busy without making a judgment from the signal sound heard from the handset of the telephone set 7. it can. Further, it can be seen that this line busy indicates that the destination facsimile machine is not operating and the line of the switching network is full.

If neither a connectable signal nor a connectable signal is not detected within a predetermined monitoring time, an error is displayed. In this case, it is considered that there is a dial signal transmission error or a malfunction of the switching network, so the operator can easily understand such a situation.

By the way, the number of call originations registered in FIG. 2 sets the number of times of re-calling when a connection disabled signal is detected. The connection disable signal described in the above embodiment is received not because the line of the destination facsimile machine is busy, but because of the busy communication line inside the switching network.

Although not described in the above embodiment, this facsimile machine recalls a call even when the destination facsimile machine is busy. If no call is made and the other party does not respond after a certain period of time has elapsed, the call is temporarily stopped and the call is reissued. If a communication error occurs after the other party responds and starts communication, the communication is temporarily stopped and the call is recalled. The number of outgoing calls for repeating the recalled calls in such three types of cases is fixedly set in advance.

Therefore, the number of calls to be registered as shown in FIG. 2 can be registered separately from the fixed number of calls. In this case, the number of calls to be registered can be set to a value larger than the fixed number of calls.

When the call is temporarily stopped due to the busy communication line in the switching network, the other party's device does not have a problem, and therefore, there is a high possibility of being able to communicate with the other party by repeating the re-calling. Therefore, it is possible to increase the possibility of successful communication by increasing the number of outgoing calls to be registered as described above.

In the above embodiment, the detection of the received signal is started after waiting the rest time after sending the dial signals of various number patterns, but the signal detection is immediately started without the rest time. You may do so.

Further, although the description has been made by taking the facsimile machine as an example, it is needless to say that the present invention is not limited to the facsimile machine and can be similarly applied to various communication apparatuses for transmitting by a dial type telephone line.

[0058]

As described above, according to the present invention, when a dial signal of a pre-registered number pattern is transmitted when a dial signal is transmitted by automatic transmission, only the registered down time is automatically set. Since the signal transmission is stopped, the operator does not need to specify the pause when inputting the dial number, and the dial operation becomes easy. When a signal received from the line is detected while the signal transmission is stopped, and the signal received under one condition registered in advance is detected, the transmission of the next dial signal is immediately restarted while another condition is received. When the reception signal of is detected, the line is immediately disconnected, so that the transmission process can be efficiently executed.
