Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for stopping ringing of a telephone used in electronic exchanges, key telephone devices, etc.

2. Description of the Related Art Conventionally, in electronic exchanges, for example, when a central control unit detects an incoming call to a central office line circuit, it determines which key telephone is to ring the incoming call, controls the call path, and transmits the incoming sound source to that key telephone. Sends a ringtone from. When a ringtone is sent to the key telephone, the key telephone rings at a volume corresponding to the volume setting, thereby allowing the user to recognize the incoming call. Then, by operating the volume as necessary, the ringtone volume can be adjusted. For example, if the ringtone is too loud and becomes a nuisance, such as an incoming call during a meeting or an unnecessary call, you can reduce the ringtone by adjusting the volume.

Problems to be Solved by the Invention However, the method of controlling the ringtone volume by manipulating the volume as in the conventional example described above has problems with polyphony.

There is a problem in that if the ringtone is once lowered by operating the system and then forgotten about, the next time a call arrives, the ringtone may be too low to recognize the call.

The present invention solves these conventional problems by being able to recognize incoming calls each time an incoming call is received, and to easily stop the incoming call ringing while an incoming call is incoming. It is an object of the present invention to provide a method for stopping ringtones.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides, by operating a preset ring stop button on a telephone that sends out a ringtone from a ringtone source when a call arrives,
This is to stop the ringing tone mentioned above.

Therefore, according to the present invention, a telephone set that sends a ringtone from a ringtone source emits a ringtone corresponding to the volume setting, thereby recognizing an incoming call, and eliminating the need for this incoming call. In some cases, by operating a preset button on the phone while receiving the call,
You can stop the ringtone.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

First, a first embodiment of the present invention will be described.

FIG. 1 is a schematic block diagram of an electronic exchange that implements a ring tone stopping method according to a first embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a button telephone set, each of which has a built-in system 2 for controlling the volume of incoming calls. 3 is an extension circuit that controls the button telephone 1, 4 is a central office line circuit that controls the central office line, and 5 is a communication path, which connects a plurality of button telephones 1.
and a plurality of station line circuits 4 are selectively connected. Reference numeral 6 denotes a ringing sound source, which is selectively connected to a plurality of key telephones 1 through a communication path 5. A central control unit (CPU) 7 controls the extension circuit 3, the central office line circuit 4, the communication path 5, the ringtone source 6, and the like. Reference numeral 8 denotes a memory for setting the stop of ring tone transmission connected to the central control device 7, and when a button of each button telephone 1 is pressed, the transmission of the ring tone from the ring tone source 6 under the control of the central control device 7 is stopped. It can be set as follows. That is, for example, when you do not want to receive any incoming calls during a meeting, you do not want to receive incoming calls from an outside line, or you do not want to receive incoming calls by the other party's number, etc., as shown in Figure 2. In the memory 8, 1 and 0 are set to indicate whether or not to stop transmitting a ringtone corresponding to the extension number of each button telephone 1.

In the above configuration, a method for stopping the ringtone will be described below.

Lift the handset of key phone 1 and take it off-hook.
When you operate the central office line button, the extension circuit 3 detects this and
The information is transmitted to the central control device 7. The central control unit 7 determines the number, controls the communication path 5 and the office line circuit 4, and acquires the office line. Therefore, by dialing the other party's number from the button telephone 1, the central control unit 7 sends it to the central office line via the extension circuit 3, the communication path 5, and the office line circuit 4, and when the other party answers, the call is made. button telephone 1 by control of route 5
You can connect the central office line and make calls. Further, when a calling signal is sent from the office line, the office line circuit 4 detects this and transmits it to the central control unit 7. Based on this, the central control device 7 controls the communication path 5 and connects the incoming sound source 6 to each key telephone 1 via the extension circuit 3. This allows each button phone 1
The ringtone will sound and you will be able to recognize the incoming call. Here, when the handset of any one of the key telephones 1 is lifted up and off-hook, the extension circuit 3 detects this and notifies the central controller 7 of the occurrence. Based on this, the central control device 7 controls the communication path 5 to disconnect the incoming call sound source 6 from the key telephone 1, and connects the central office line and the button telephone 1 by controlling the communication path 5, so that a call can be made.

Then, when each button telephone 1 is emitting a ringtone as described above, it is determined whether or not this incoming call is unnecessary. For example, the ring tone is set to be different for incoming calls from an internal line and for calls from an external line, so if the call is from an internal line, it is necessary and accepted, but if the call is from an external line, it is not necessary. The system determines whether or not to accept the call based on the ringtone type, or, if it is equipped with a caller number display function, whether or not it is necessary to accept the call using the displayed caller number. or, if you are in a meeting, determine that all incoming calls are unnecessary. If you judge that the incoming call is unnecessary, press the preset ring stop button on the button telephone 1 while the incoming call is ringing, and the information will be detected by the extension circuit 3 and sent to the central control unit. 7 can be conveyed. Based on this, the central control device 7 stores the memory 8 for ring tone transmission stop setting.
A search is made to determine whether or not the key telephone 1 of the extension number whose ringing stop button was operated has been set in advance to stop sending out ringtones, as shown in FIG. If the setting of memory 8 is 0, that is, it is not set,
Since the ringtone source 6 continues to be kept connected, the ringtone continues to sound. If the setting in the memory 8 is 1, that is, if it is set, the central controller 7 controls the call path 5, disconnects the ringing sound source 6 from the button telephone 1,
The transmission of the ring tone is stopped, and the ring tone of the button telephone 1 is stopped. Next, when the key telephone 1 receives a call again, the central controller 7 controls the call path 5 in the same manner as above and connects the ring tone source 6 to the key telephone 1, so that the key telephone 1 returns to the volume 2 setting. The incoming call will ring at the appropriate volume, allowing you to recognize the incoming call. Therefore, it is possible to select between making a call and stopping the incoming ringing by pressing the button for stopping the ringing as described above.

As described above, according to the above embodiment, the memory 8 for ring tone transmission stop setting is set to stop transmitting the ring tone when the button operation of the button telephone 1 makes it unnecessary to receive a call. , When there is an incoming call on key telephone 1, first,
The central controller 7 controls the communication path 5 and sends a ringtone from the ringtone source 6 to the button telephone 1, and the button telephone 1 generates a ringing tone according to the volume setting, thereby recognizing the incoming call. This incoming call can be classified as an incoming ringing sound,
If the other party's number display function is determined to be unnecessary due to a meeting being in progress, etc., by operating the buttons on the button telephone L while the call is incoming, the central control unit 7 will refer to the memory 8 for ring tone transmission stop settings. However, if the memory 8 is set to stop transmitting a ring tone to the key telephone 1 when a button is operated as described above, the call path 5 is controlled and an incoming call is sent from the ring tone source 6 to the key telephone 1. It is possible to stop the sound transmission and stop the telephone from ringing. Therefore, for example, you can stop the ringing and ignore all incoming calls during a meeting, or you can only accept calls from the desired party and ignore all other calls by stopping the ringing. . Further, since the ringing of an incoming call is stopped by pressing the button as described above, the ringing of the incoming call can be easily stopped.

In addition, since it is possible to decide whether or not to use this function for each button telephone 1 according to the settings in the memory 8 for ring tone transmission stop settings, it is possible to prevent incoming calls from being stopped due to erroneous operation. can.

Next, a second embodiment of the present invention will be described.

FIG. 3 is a schematic block diagram of a standalone telephone that implements the ringtone stopping method according to the second embodiment of the present invention.

In FIG. 3, 11 is an input terminal, 12 is a switch circuit, 13 is a volume, and 14 is an amplifier. 15 is a speaker,
Reference numeral 16 denotes a ringtone rising detection means which is activated when detecting that a ringtone is input to the input terminal 11, and is configured not to operate when the ringtone is intermittent. Reference numeral 17 indicates a button for stopping ringing, and reference numeral 18 indicates an operation of the ring tone rising detection means 16 and the button 17 for stopping ringing.
This is a flip-flop circuit that controls N and OFF.

In the above configuration, a method for stopping the ringtone will be described below.

When a ringtone is input to the input terminal 11, the detection means 16 detects the rise of the ringtone. This detection signal inverts the flip-flop circuit 18, and its output is used as the switch circuit 1.
Turn on 2. This will change the ringtone to poly, -m13,
The signal is applied to the speaker 15 via the amplifier 14, and the incoming call can be sounded at the volume set by the volume 13. If it is determined that the incoming call is unnecessary during an incoming call, the button 17 for stopping the ringing is suppressed to return the flip-flop circuit to its original state and turn off the switch circuit 12.
to stop the ringing.

Note that a microcomputer may be used instead of the flip-flop circuit 18.

Effects of the Invention As described above, according to the present invention, the telephone that sends the ring tone from the ring tone source emits the ring tone according to the poly-me setting, which makes it possible to recognize the incoming call. If the incoming call is not required, the ringing can be stopped by operating a preset ringing stop button on the telephone while the incoming call is incoming. Therefore, each time an incoming call is received, it is possible to recognize the incoming call, and if the incoming call is unnecessary, the ringing of the incoming call can be easily stopped during the incoming call.
