Abstract

PURPOSE:To control the operation of an automatic answering telephone system, which is set in a separate place from any key telephone set by obtaining a role as the operating terminal equipment of the automatic answering telephone system in the plural key telephone sets. CONSTITUTION:The plural key telephone sets is caused to obtain the role as the terminal equipment of the automatic answering telephone system and a dial signal to be set in advance is transmitted from any key telephone set through an extension. Then, the automatic answering telephone system is caused to be preparing condition and remote control can be executed. Further, since the operation of a recording or reproducing is executed by the key telephone set during a calling by a line wire, a calling recording or a reproducing sending can be executed without operating a special switching to the line wire. Thus, a convenient automatic answering telephone system can be formed.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an answering machine that connects to a telephone line having a central office line and an extension line using a plurality of button telephones such as a home telephone. be.

(Conventional technology) FIG. 2 shows the configuration of a conventional answering machine.

In the figure, 1 is a DC circuit, and 2 is a calling signal detection circuit, which are connected to a central office line.

3 is a remote control signal detection circuit;
4 is a communication circuit, which is connected to the office line via the DC circuit 1. Reference numeral 5 denotes a recording and reproducing circuit, which records the audio signal of the telephone call circuit 4 and sends out a reproduced signal. 6 is a control circuit, which includes the calling signal detection circuit 2 and the remote control detection circuit 3.
The telephone answering machine operates according to signals from the telephone answering machine. 7 is an operating section, which can also be operated directly by hand.

Next, the operation will be explained. In fig.

The calling signal detection circuit 2 is a circuit that detects 16 signals, which are calling signals from one office line, and constantly monitors the office line. If a calling signal is received at this time, the detection signal is sent to the control circuit 6 and the answering machine is activated. That is, the DC circuit 1 is closed, and a signal from the central office line is sent to the remote control detection circuit 3 and the telephone call circuit 4, thereby performing operation as an answering machine or remote control operation.

(Problem to be solved by the invention) Even if an answering machine is connected to a telephone line that has a central office line and an extension line like the conventional home telephone mentioned above, the ringing signal of the extension line is completely different from the ringing signal of the central line. Therefore, this answering machine cannot be started.For reasons more than 0, it is impossible to receive or pass signals between the extension and the answering machine, so no matter how many key phones there are, it is difficult to operate the answering machine. If you want to do so, you have to go to the installation location.

An object of the present invention is to eliminate the drawbacks of the conventional system, to enable an answering machine to be activated from any key telephone connected by an extension, and to control operations such as setting, confirming, and canceling the answering machine. be. That is, an object of the present invention is to provide a more user-friendly answering machine system in which a plurality of key telephones serve as terminal equipment of an answering machine.

(Means for Solving the Problems) The answering machine system of the present invention has a plurality of telephones installed, and one button telephone system that can make calls to a central office line and an extension.
In an answering machine system in which an answering machine is connected to an extension with a central office line remote control function, the answering machine can be put into a ready state by issuing a preset dial signal from any key telephone via the extension. This allows for remote control, and
It has a function to detect the hook-up of a key telephone connected in parallel to the answering machine on the line, and when this is detected, the answering machine is stopped. It has a function to detect the hook-up of series-connected key telephones, and upon detecting this, the answering machine can record and reproduce the call only at this time.

(Function) According to the present invention, an answering machine can be activated from any of a plurality of key telephones connected by an extension,
In addition, the operations of the answering machine, such as setting, canceling, confirming, and recording messages, can be controlled by pressing the dial button from each button telephone.

Further, in the case of a call interruption by the button telephone while the answering machine is in operation, or when a call is received from a telephone that is recording or is being set, the operation of the answering machine can be automatically stopped.

Furthermore, by performing a recording or playback operation during a call on an outside line using a button telephone, it is possible to record or reproduce and transmit a single call without performing a special switching operation for that outside line.

(Example) An embodiment of the present invention will be described based on FIG.

FIG. 1 shows the configuration of an answering machine system according to the present invention. In this figure, the same parts as those in the conventional example shown in FIG. 2 are given the same reference numerals, and the explanation thereof will be omitted. 8
1 is a line switching section, which switches between an internal line and an outside line in response to a signal from the control circuit 6. A loop detection circuit 9 is connected in series to the line and detects hook-up of a key telephone. 10 is an extension signal monitoring circuit;
Always connected to your extension. 11 is an auto-disconnect circuit that monitors changes in the line.

Next, the operation will be explained. When you press the dial button on the button telephone to send a dial signal to the extension line,
The extension signal monitoring circuit 10 looks at the signal and sends a signal to the control circuit 6 only if it matches a preset 2- to 4-digit remote control mode transition number. Then, the control circuit 6 closes the DC circuit 1 and connects the extension line, the communication circuit 4 and the remote control signal detection circuit 3. The operation from then on is exactly the same as a conventional remote control from an outside line.

Next, when a key telephone connected in series to the line is hooked up to grab an outside line, the loop detection circuit 9 detects it and sends the signal to the control circuit 6. At this time, when the operating section 7 of the answering machine is set to the recording state, the outside line call signal is recorded, and when the answering machine is set to the playback state, the reproduced sound is sent to the outside line. Even if you perform this operation when the key telephone connected in series to the line is not hooked up, the recording will only be played back from the answering machine's microphone and speaker.

Next, when the telephone answering machine hooks up a key telephone connected in parallel to the line and grabs the outside line while the telephone answering machine is operating as an answering machine, the auto-disconnect circuit 11 is activated and the telephone answering machine stops its operation. , is opened in the DC circuit 1 and disconnected from the line.

(Effects of the Invention) According to the present invention, a plurality of key telephones have the role of operating terminal equipment for an answering machine, and any key telephone can control the operation of a remote answering machine. Furthermore, it detects that the key phone is hooked up and stops the answering machine and records the call.

The system automatically switches to playback and transmission mode, greatly improving operability and having great practical effects.
