JP3125961U - Composite adapter for communication terminals - Google Patents

Abstract

Conventionally, when communication or a telephone call is attempted using a public line, free communication or pay communication cannot be effectively used. In the present invention, at least one public line is connected and at least one communication terminal device is connected, and a telephone number sent at the other party's outgoing call or a signal sent to the public line is determined to determine whether it is free communication or paid communication. An adapter is provided for informing the notification unit.
A dial number is recognized and determined, and a notification unit is provided. The composite adapter can be easily connected to an existing telephone or communication terminal device, and when a call is made, a charge or free charge can be clearly identified from the user or a nearby person. In addition, since an informing unit is provided, it is possible to check for free and paid if the call is made as usual without having to check the number or listen to the sound and make a decision for free of charge.

Description

  The present invention is a device for connecting to a communication terminal device such as a telephone to improve convenience.

  In the case where a conventional telephone or the like uses a cheap line, there is a service in which a charge is reduced by adding to a normal dial number and dialing. In addition, there is a service that can realize a free call if a line is selected properly, for example, an IP phone is a line that realizes a free call. Currently, there is a service that allows you to make cheap calls by dialing 4 to 6 digits at the beginning of your mobile phone number.

  However, it is natural to dial the other party's dial number, but if the person who forgets to dial the additional number and dials a person who does not know that the charge will be reduced, the connection will remain without the number. Become. In such a case, the precious service could not be used effectively. In some cases, free calls are also free, even though it is free calls without knowing whether to pay or not, it was easy to finish things that should be spoken in detail over time . On the other hand, even though it was a toll call, I talked for a long time, and I could not use the free call service. In particular, IP phones, etc., are usually free toll if the other party is the same IP phone company, but it is mistakenly judged as free even between different IP phone companies, resulting in communication costs exceeding expectations. It sometimes happened.

  In addition, it is natural to put the handset on the ear during a call and return it to the place where the handset of the telephone body is placed when the talk is over. However, in this case, if the handset is not firmly on the telephone body, the situation is the same as when the handset is raised. This is very inconvenient. In other words, the exchange cannot make an incoming call in this state. The inconvenience of not being able to receive emergency calls as well as calls from outside occurred. Furthermore, if the handset is disconnected and it has been standing for a long time, it cannot be immediately sent even if the handset is returned. This is because the office switch does not operate immediately even if the telephone is turned off and the handset is returned because the station switch has been in a long state.

  In addition, if the user is not specified, depending on the destination, there are cases where it is much higher than the normal call charge, so it will become a problem later by looking at the charge, and the other party who should not make a call is also unaware Troubles often occurred.

  The present invention connects at least one public line and at least one communication terminal device, determines the telephone number sent when calling the other party or the signal sent to the public line, and determines whether the communication is free or paid. An adapter characterized by notifying the notifying unit is a first device, and at least one public line is connected and at least one communication terminal is connected, and a signal sent to the public line at the time of non-calling is transmitted. An adapter characterized by determining and notifying the notifying unit is a second device, wherein at least one public line is connected and at least one communication terminal device is connected, and a telephone number transmitted at the time of outgoing call is determined. If it is determined that the connection is not desired, a third consideration is an adapter characterized by disconnecting the public line and the communication terminal device. Connect at least one public line and at least one communication terminal device, determine the telephone number sent when calling the other party, add the desired additional number to the sent telephone number, and then the public line A third aspect of the present invention is to solve the above-mentioned problems by using a composite adapter characterized in that a dial is transmitted to the dial.

  FIG. 1 is a block diagram of a composite adapter for a communication terminal according to an embodiment.

  This will be described with reference to FIG. A line 2 and a telephone 3 are connected to the adapter 1. The line 2 is a general public line, a public line, an IP telephone line, or the like. A coupling unit 7 is configured between the telephone 3 and the line 2. This coupling unit 7 detects the voltage and current when the telephone 3 is picked up and the function for taking out the dial signal from the telephone 3, or the coupling function for sending the dial signal to the line 2, and the telephone 3 is turned on. Has the function to judge.

  The coupling unit 7 is connected to the dial transmission / reception unit 5, the CPU 4, and the determination unit 6. A notification unit 8 is coupled to the determination unit 6. The notification unit 8 includes LEDs and includes a green LED and a red LED. Although not shown in the figure, power is supplied to control each part. The CPU 4 has a memory for storing dial numbers and values necessary for operation.

  Next, the operation when the user actually uses it will be described. When the user lifts the receiver 3, the coupling unit 7 can easily detect it, so the CPU 4 temporarily disconnects the line 2. The user then dials the dialed number. This number is recognized by the dial transmission / reception unit 5, and the additional service number that makes the call charge cheaper is dialed on the line 2, and the dial transmission / reception unit 5 is operated to perform dialing. This dial number is stored in advance in the memory unit of the CPU 4. If the additional service number is 0011, after dialing 0011 to the line 2, the telephone number sent from the telephone 3 is dialed. The user only needs to dial the telephone number of the other party, and even if a user who does not know at all uses it, a call with the additional service function can be established.

  Further, the operation when the current call is a free call will be described. For example, a general public line can be easily understood by changing the polarity of the connected line, that is, + and − when a telephone call is charged. That is, since the direction of the polarity of the voltage applied to the line 2 can be recognized by the determination unit 6 at the time of calling from the telephone 3, the control unit 4 activates the notification unit 8 to notify whether it is a pay call. For example, the user can easily determine that the notification unit 8 is charged if the red LED is turned on. Conversely, if + and-are not changed, that is, if the call is free, the free call is made if the green LED is lit on the notification unit. In recent IP telephones, it is known that calls between the same providers are free calls. In this case, the station receives more signal sound when dialing. This signal sound is different from the connection at the time of a paid call and the connection at the time of a free call, and it can be easily judged by listening to this sound. In other words, the judgment unit 6 listens to this signal sound and transmits it to the CPU. The CPU judges the signal sound of the paid pattern and the signal sound of the free pattern, and if it is executed in the same manner as described above, it is free by seeing the color of the LED. Whether it is a call or a paid call can be determined from the outside, for example, without being a user.

  In addition, even if the difference between free and paid is the change of +-polarity of the above-mentioned polarity or signal sound, if the input to the judgment unit 6 is matched to the charged or free signal of the line, it will be notified in the same manner as described above. Is possible. In addition, it may be determined whether the other party's dial number is a paid call or a free call. Specifically, in the case of an IP telephone network or the like, the provider can be identified by a number of several digits after 050. That is, when the number is the same provider as the provider used by the user at the time of outgoing call, since the free call connection is established, it is only necessary to inform the notification unit 8 that it is free. Further, as long as it is possible to determine whether the other party dial number is free or charged even if it is not an IP telephone network, the other party number may be notified of free or paid.

  Next, the operation when the user puts the handset after the call is finished but the handset is displaced, or when the handset is disconnected will be described. Since the handset is raised, a busy tone is transmitted from the general public line office exchange after a while. This busy tone is called busy tone, and is a repeated pattern with a single frequency of 400 Hz for 0.5 seconds and a 0.5 second stop. That is, since the coupling portion 7 of the adapter 1 is connected to the line 2, the signal sound can be taken out. The CPU 4 determines whether this sound transmission pattern is a busy pattern and the frequency is 400 Hz. If it is determined that the sound is a busy sound, the LED is turned on in red for the notification unit 8. That is, when the handset is in the raised state, the red LED lamp is lit, so that the state in which the handset is raised can be easily understood from the outside. If the user returns the handset, the busy sound stops. Therefore, since the CPU can determine the stop as described above, the red LED lamp is turned off. In the description here, the red LED is turned on. However, if the alarm unit 8 is buzzed or the like and a warning is given by sound, it is possible to recognize the LED of the alarm unit 8 even if it is not visible.

  Next, the operation when the destination is restricted will be described. The other party's dial is sent from the telephone 3 side. The dial number can be recognized by the dial transmission / reception unit 5 through the coupling unit 7. That is, a number that is not desired to be stored in the memory unit in the CPU 4 is stored in advance, and when the number matches, the CPU 4 disconnects the coupling unit 7 from the line 2. Then, the dial from the telephone 3 is not sent to the line 2, and the transmission is terminated without establishing the transmission. Similarly, it is possible to easily determine why the user could not make a call by turning on or blinking LED red on the notification unit 8. Similarly, a buzzer or the like may be sounded, or a warning sound may be transmitted from the handset 3 of the telephone 3 through the coupling unit 7.

  In the explanation, the operation is performed when a telephone is connected. However, the operation is not limited to the telephone but may be any apparatus that uses a communication line such as a facsimile machine or a modem terminal. Can be prevented. In other words, if the facsimile number of the other party to be transmitted in advance is registered in the CPU 4, when the dial number from the facsimile arrives, the dial number is compared with the number in the memory, and if it matches, the communication is maintained as it is. If the dial number does not match, the line and the facsimile are disconnected to disconnect the communication, thereby preventing an erroneous facsimile.

Effect of device

  The composite adapter according to the present invention can be easily connected to an existing telephone or a communication terminal device, and when a call is made, it can be clearly understood from the user and nearby people whether there is a charge or no charge. In addition, since an informing unit is provided, it is possible to check for free or paid if the call is made as usual without having to check the number or listen to the sound and make a decision for free of charge.

  In addition, since it is no longer possible to receive a telephone call due to forgetting to return the handset such as a child or an elderly person, it is possible to secure a safe life for the user and there is no doubt that it will contribute to society.
