Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents a predetermined telephone number signal from being transmitted to a subscriber line, thereby preventing a telephone call from being made by a telephone subscriber or a telephone payer. The present invention relates to a call control device to be prevented.

[0002]

2. Description of the Related Art International calls can be made by dialing an international telephone number from a telephone. However, call charges are higher than domestic calls. In some cases, an international call is connected to the other party, and a huge call fee is charged later. To avoid this from happening,
A regulating means for detecting an international telephone number signal from a dial and preventing the transmission of the international telephone number signal to the subscriber line is provided inside the telephone, and this restricting means is provided when the domestic telephone number signal is transmitted. It is conceivable to design the telephone so that the number signal can be sent to the subscriber line as it is, and the international telephone call itself, which requires a large fee, cannot be made.

[0003]

By using such a telephone, it is possible to prevent an expensive telephone call from being charged by an international call that is not desired by a telephone subscriber or a payer, but the international call itself is not possible. Therefore, it is not suitable for homes or business establishments that may make international calls.

Accordingly, an object of the present invention is to provide a call restricting device which can prevent a high-priced call which is not intended by a telephone subscriber or a payer, and which can make such a call when necessary. And

[0005]

In order to achieve this object, a call restricting apparatus according to the present invention is provided in a telephone or connected between a telephone and a subscriber line, and a telephone number signal is transmitted to the telephone. A call restricting device that can prevent the telephone number from being sent to a subscriber line from a telephone line, a detecting unit that detects a type of a telephone number signal from a telephone dial, and a telephone number based on the type detected by the detecting unit. A telephone number signal restricting means having a switching unit for transmitting or blocking a signal to a subscriber line; and switch means for incorporating the telephone number signal restricting means into the telephone line and removing the telephone number signal from the telephone line. The switch means is provided so that it can be operated from the outside. If the telephone line is formed by removing the telephone number signal restricting means by operating the switch means from the outside, that is, if the telephone line is formed without passing through the telephone number signal restricting means, the telephone can perform normal telephone functions. It is also possible to make international calls and domestic distant calls.
If the telephone number signal regulating means is incorporated (connected) into the telephone line by operating the switch means from the outside, that is, if the telephone line is formed via the telephone number signal regulating means, a specific type of telephone number signal Outgoing to the subscriber line is blocked. Therefore, a telephone call cannot be made by dialing a specific type of telephone number from a telephone, for example, by dialing an international telephone number. The switch means can be operated by, for example, inputting a personal identification number from a dial.However, in order to enable simpler and more effective operation, the call control device must be connected to a telephone and a subscriber line. A connection line means for connecting a telephone and a subscriber line, and a call originating from the telephone. A telephone number signal restricting means, comprising: a detecting unit for detecting the type of the telephone number signal obtained; and a switching unit for transmitting or preventing transmission of the telephone number signal to the subscriber line based on the type detected by the detecting unit. Switch means for selectively incorporating the telephone number signal regulating means and the connection line means into a telephone line, wherein the switch means is externally operated. It is preferably configured to allow, with a structure that.

[0006] If the connection line means is incorporated (connected) into the telephone line by operating the switch means from the outside, that is, if the telephone line is formed using the connection line means, the connection is directly made to the subscriber line. The telephone can be used in the same manner as described above. If the telephone number signal regulating means is incorporated (connected) into the telephone line by operating the switch means from the outside, that is, the telephone line is formed using the telephone number signal regulating means. If
Although the transmission of a specific type of telephone number signal to the subscriber line is prevented, the call restricting device can be configured so that ordinary people can easily connect to an existing telephone.

[0007] It is relatively common for telephone subscribers or telephone payers to want to restrict only international calls, but when only international telephone numbers are subject to restriction, the difference in the number of digits from domestic telephone numbers is used. That is a good idea. At present, domestic telephone numbers are composed of a maximum of 9 digits, and international telephone numbers are often 10 digits or more. Therefore, when a telephone number signal of 10 digits or more is transmitted, transmission to a subscriber line is prevented. By configuring the switching unit as described above, most international calls can be blocked, and domestic calls can be made without any trouble.

When the telephone number signal regulating means is incorporated in the telephone line, it is preferable that a child or the like operates the switch means so that the connecting line means cannot be incorporated in the telephone line. For this purpose, the switch means is configured to be operated by a removable rotation switching key, and the rotation switching key can be extracted in a state where the switching unit is incorporated in the telephone line. Good. To operate the switch means, it is necessary to insert and rotate a rotation switching key.
