Abstract

PURPOSE:To use one line for a telephone set and a facsimile equipment or the like in common by energizing a calling bell when an intermittent signal is consecutive for a prescribed time or a prescribed number of times. CONSTITUTION:When a call signal from an exchange 11 is consecutive for 5 sec or over in a reply device 12, it discriminates that the signal is a call to a telephone set 19. When a call signal stops within 5 sec and a recall exists within 6 sec and the call signal is consecutive for 1 sec, it is decided to a call to a facsimile reception equipment 20. While a network access equipment 1 calls an opposite party when the facsimile transmission is instructed, the equipment 1 hooks on once after 3 sec and the opposite party is called again after 5 sec.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a call answering method in a communication device such as a telephone or facsimile machine connected to an exchange. The system is configured so that a bell rings immediately in response to a call from the exchange. In addition, if such a telephone and facsimile device are shared by a single line from the exchange, transmissions from the other party's facsimile device will only be possible if the user has previously connected the line to the facsimile device. It is configured to be able to receive messages automatically, and normally the line is connected to the telephone side, and when used as a facsimile device, the user generally switches to the facsimile device after communicating with each other by phone. [Problems to be solved by the invention] In conventional telephones, facsimile machines, etc., the bell rings immediately in response to a call from the exchange, so noise from the exchange or an erroneous call (especially if the caller does not notice it) When disconnecting immediately), the bell often rings several times and then stops, causing discomfort to the user.

In addition, when a telephone and a facsimile device are shared by a single line from an exchange, the line is usually connected to the telephone side, so transmissions from the other party's facsimile machine cannot be automatically received, and one line is connected to the telephone side. If you are connected to a facsimile machine and the other party calls without your knowledge,
A harsh sound will come back and cause discomfort. Therefore, it is common for telephones and facsimile machines to be connected to separate lines of an exchange.
There were problems such as increased costs.

An object of the present invention is to provide a call answering system that distinguishes normal calls from unnecessary calls such as noise from exchanges or erroneous calls, and prevents the bell from ringing in response to unnecessary calls such as noise. It is about providing.

Another object of the invention is to:
A call answering system that distinguishes between calls to a telephone and calls to a non-telephone such as a facsimile machine, and that can automatically receive transmissions from the other party's facsimile machine when line 14 is shared by a filling machine and a facsimile machine, etc. It is about providing.

[Means and effects for solving the problem] The present invention provides a communication device such as a telephone or a facsimile machine connected to an exchange, in which an intermittent signal (ring tone signal) generated by a call from the exchange is transmitted for a predetermined time or a predetermined time. The main feature is to monitor whether or not the number of repetitions continues, and if it continues, to ring the bell for the first time. This results in
It is possible to prevent the bell from ringing in response to unnecessary calls such as noise from a switchboard or an erroneous call. Further, the present invention provides that when the above-mentioned intermittent signal is interrupted before reaching a predetermined time or a predetermined number of times, and the operation in which the intermittent signal arrives again within a predetermined time is repeated a predetermined number of times, a non-telephone device such as a facsimile machine The non-telephone is determined to be a call, and the non-telephone is made to respond. As a result, one line can be shared by a telephone and a facsimile machine, etc., and transmissions from the other party's facsimile machine etc. can be automatically received, and normal telephone calls can be received by a person.

,〔Example〕 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall configuration diagram of an embodiment of the present invention. In FIG. 1, on the calling side, a telephone (A) 10
is connected to the exchange 11 via a line 101, and the facsimile transmitting device 9 is connected to the exchange 11 via a line 102 via the network access device 1. On the other hand, on the called side,
A telephone (B) 19 and a facsimile receiving device 20 are connected to an exchange 11 via a response device 12 and a single line 103. Network access group [1 is communication instruction switch 2
．． Dial operation unit 3, dial register 4, dial signal generation unit 5, network access control unit l-6
, a timer (A) 7, and a network control unit 1-8. The response device 12 also includes a network termination unit 13, a call detection unit 14, a response control unit 15, a switch 16,
It consists of a timer (B) 17 and a call end detection unit 18.

In the following description of this embodiment, the response device 112 is
If the call signal from 1 continues for 5 seconds or more, it is determined that the call is to telephone 19.

If the readout signal stops within 5 seconds, and then there is a call again within 6 seconds, and the call signal continues for 1 second, it is determined that the call is to facsimile receiving device R20. Correspondingly, when the network access device 1 is instructed to send a facsimile, it calls the other party, goes on-hook three seconds later, and then calls the other party again five seconds later.

First, a case will be described in which a transmission from the facsimile transmitting device 9 is automatically received by the facsimile receiving device 20.

To send the facsimile 9, enter the recipient's dial number from the dial operation unit 3, and enter the dial number from the dial register 4.
record the dialed number. Next, the sender sends communication instructions to the network access control unit 6 via the communication instruction switch 2.
tell to. The network access control unit 6 sends a signal to the network control unit 8 to set the switch 11 in a hook-off state, and when the switch 11 receives a response signal from the network control unit 8, it is stored in the dial register 4 in advance. A signal for transmitting the dial number is sent to the dial signal generating unit 5, which converts this into a dial signal and sends the dial signal to the exchange 11 via the network control unit 8. When the calling signal from the exchange 11 passes through the network control unit 8 and stays at the network access control unit 6, the network access control unit 6
sets timer (A) 7 for 3 seconds.

When the network access control unit 6 is activated 3 seconds after the timer (A) 7, the network access control unit 6 sends a signal to the network control unit 8 to set the switch 11 to the hook-on state, and then the timer (A) is activated. ) Multiply 7 by a 5 second time set. When the network access control unit 6 is activated after 5 seconds, the network access control unit 6 puts the network control unit 8 into a hook-off state with respect to the exchange 11, similar to the first activation from the communication instruction switch 2, and the exchange 11 After receiving the response signal from the switch 11, control is performed to send the dial signal to the exchange 11 again.

Next, when the network access control unit 6 receives a signal from the network control unit 8 indicating that the calling signal from the exchange 11 has been interrupted and the other party is in a response state, it instructs the facsimile transmitter 9 to send a facsimile signal. do. A facsimile signal from the facsimile transmitter 9 is sent to the exchange 11 via the network control unit 8. When the sending of the facsimile signal is finished, the facsimile transmitting device 9 sends a completion signal to the network access control unit 6. Based on this signal, the network access control unit 6
The footer is turned on and the control state is returned to the initial state.

On the other hand, the answering device 111 receives a call from the exchange 11.
2 detects a call signal with a call detection unit 14 and transmits it to a response control unit 15.

The response control unit 15 sets a timer (B) 17 for 5 seconds, sets the switch 16 to the initial state of terminal 1, and causes the network termination unit 13 to terminate the signal from the exchange 11. The ringing signal stops within 5 seconds,
When this is transmitted from the call detection unit 14, the response control unit 15 re-sets the timer (B) 17 for 6 seconds. If a call is sent again from the call detection unit 14 within the 6 seconds, the response control unit 15 sets the timer (B) 7 to 1 second, and if there is one call within 1 second, the response control unit 15 initializes the internal state. Return to state. Also, if the response control unit 15 is activated one second after the timer (B) 17 and a call is still being detected, the response control unit 15 switches the switch 6 to the terminal 3 and transmits the signal from the exchange 11 to the facsimile receiving device. 2
o and activates the facsimile receiving device 20. When the facsimile receiving device 1t20 finishes receiving the facsimile signal, it sends a termination signal to the response control unit 15, and the response control unit 15 returns the switch 16 to the terminal 1 and returns to the initial state. Further, even when the response control unit 15 is activated from a 6-second timeout from the timer (B) 17, it determines that the previous call was due to noise from the exchange 11, and returns to the initial state.

Next, the answering device 1 responds to a call from the telephone (A) 10.
The second operation will be explained. In this case as well, in response to a call from the exchange 11, the call detection unit 14 operates as described above, and the response control unit 15 sets the timer (B) 17 to 5 seconds. Next, after 5 seconds have passed, the response control unit 1 is activated by the timer (B) 17.
5 connects the switch 16 to the terminal 2, and the telephone (B) 1
Ring the bell at 9 to complete the call.

When the call ends, the response control unit 15 connects the switch 16 to the terminal 1 in response to a signal from the call end detection unit 18, returning to the initial state.

In the above embodiment, time monitoring is used to distinguish between unnecessary calls such as noise, calls to a telephone, calls to a facsimile machine, etc. However, it is also possible to monitor the number of intermittent call signals. .

〔Effect of the invention〕

As explained above, according to the present invention, in the case of communication from a facsimile etc., it is connected to a facsimile receiver etc., and in the case of communication from a normal telephone, it is connected to the telephone and the bell rings, allowing the same communication as normal. If the call is due to noise from the exchange.

Since these calls are removed, calls from a single line from the exchange can be separated into invalid calls, facsimile calls, and telephone calls, which eliminates the discomfort caused by unnecessary calls and further promotes the spread of facsimile services. There are increasing benefits.
