Abstract

PURPOSE:To prevent an ID code from being known to a telephone user and to simplify dialing by detecting a dial number from a telephone set and adding a registered ID code automatically to the number when it is decided to require the transmission of the ID code and sending the dial. CONSTITUTION:In dialing a number from an operating section 12 of a telephone set B, the signal is detected by a control circuit 10 and sent to a control circuit 4 of a master set A via transmission/reception circuits 11, 8. A deciding circuit 7 informs it to the control circuit 4 if a number requiring an ID code such as request of credit call service in the dial signal. Then the control circuit 4 inserts the ID code registered in the memory 5 to a predetermined position of the dial signal and sends it to a line 1. Then the dialing of the ID code is omitted. Moreover, even if no ID code is informed to the telephone set user, the specific service utility is used.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a key telephone device having a function that requires transmission of an ID code at the time of making a call in order to use a line, such as a credit card call.

Conventional technology Traditionally, telephone lines were operated by Nippon Telegraph and Telephone Corporation (NTT)2.
There was only one Beno company, but due to the enactment of the new Telecommunications Business Law, DD
New type 1 telecommunications carriers (NCCs) such as I, JAPAN-EC0M, and others have started owning telephone lines and providing various telephone line services to users. When using a contracted line for credit card calling, which is one of these various services, when making a call, an ID (identification) code such as a user number or PIN code is added to the dial, allowing you to pay for the call. You can use credit etc.

FIG. 2 shows an example of the NCC credit call numbering system. As shown in the figure, the caller dials the connection provider number, followed by the service request number, ID code, and telephone number of the other party.

Even with current key telephone devices that accommodate a plurality of lines, if the caller manually dials the ID code described above, it is possible to receive credit services and the like.

Problems to be Solved by the Invention However, with conventional key telephone devices, the caller must manually dial the ID3-7 code when making a call; therefore, the ID code must be communicated to the key telephone user. First, there is a risk that this ID code may be misused for a private phone. Furthermore, since the ID code includes the user's number and personal identification code, there are problems such as a large number of dialed digits, which significantly reduces dial operability and is inconvenient.

The present invention solves these conventional problems, and detects the dialed number at the time of dialing, and if it is determined that there is a need to send an ID code, it automatically adds an ID code and dials. This can prevent the ID code from being known to the telephone user, and also allows the user to easily perform dialing operations.
The object of the present invention is to provide a button telephone device having two functions.

Means for Solving the Problems In order to achieve the above object, the present invention provides a main device accommodating a plurality of lines with a code storage memory that can be registered only by a specific person, and a terminal (two telephones housed in the telephone). a determining means for detecting a dialed number and determining whether it is necessary to send an ID code; and when the determining means determines that it is necessary to send an ID code, the above-mentioned ID code storage memory is placed in a dial position designated for the line; The system is equipped with a means for automatically adding an ID code registered in the ID code and dialing the ID code.

Effects The present invention has the following effects due to the above configuration. In other words, the ID code can be automatically sent without the telephone user having to dial the ID code when performing a dialing operation that requires sending the ID code.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings. FIG. 1 is a block circuit diagram showing, as an embodiment of the present invention, a four-wire button telephone device using a microconbeater in the main device and the telephone circuit.

In FIG. 1, A is the main device and B is a telephone.

5 Beso main device A includes line 1, dial sending circuit 2 of line 1,
A telephone call circuit 3, a control circuit 4 that implements a microcomputer and controls the entire device using its software, an ID code storage memory 5, an ID code registration circuit 6, and a dial number determination circuit 7.
, a data transmission/reception circuit with telephone B (including a power supply circuit to telephone B) 8 is provided. Telephone B includes a telephone call circuit 9, a control circuit 10, a transmitting/receiving circuit 11, an operating section 12 consisting of a central office line button, a function button, a dial, and a display circuit.
is provided. Reference numeral 13 denotes a call and data line connected between main device A and telephone B.

Next, the operation of the above embodiment will be explained.

When an ID code (user number, password, etc.) is set in the ID registration circuit 6, this ID code is registered in the ID code storage memory 5 by the control circuit 4. This registration can only be done by a specific person. When the telephone B is used, when the caller dials from the operating section 12, this dial is detected by the control circuit 10, and the dial signal is sent to the control circuit 46 of the main device A via the transmitter/receiver circuit 11.8. It will be done. The control circuit 4 operates the dial sending circuit 2 of the corresponding line 1 to send a dial to the line 1. At this time, the dial number determination circuit 7 constantly determines whether or not the dial signal includes a number requiring transmission of an ID code, and notifies the control circuit 4 of the presence or absence. Now, if the caller uses the number system shown in Figure 2 for a credit card call, for example, as shown in Figure 3 (a), the service request number follows the service provider number (for credit card calls, dial "51"). , when the other party's telephone number is dialed, the dial judgment circuit 7 of the main device A determines that the dial sent from the telephone B includes a number ("51" in this example) for which an ID code needs to be sent. This is detected and the control circuit 4 is notified of this. The control circuit 4 then reads the ID code registered in the ID code storage memory 5 and adds this ID code after the service request number as shown in FIGS. 2 and 3(b). A dial is sent, and then the telephone number of the other party is sent.In this case, an electronic key telephone device is generally used.

Now, the dialing operation on telephone B is clearly faster than the timing when main device A sends the dial to line 1, so before main device A sends the ID code, telephone B can receive the other party's phone number. The dial signal is sent to the control circuit 4, but in order to cover this time difference, a method is used in which the dial signal sent from the telephone B is temporarily stored in the dial buffer memory in the main device A, and the time-related processing is There is no problem because it can be easily processed by using this memory.

In this way, according to the above embodiment, since the registration of the ID code is performed by the main device A, only a specific person who manages the main device A can manage the ID code, and there is no need to send the ID code. In the case of dialing, it is possible to automatically determine whether transmission is necessary or not, and automatically add an ID code to a pre-specified position. Therefore, the ID code is not known to the telephone user, and the user can omit dialing operations for the ID code.

In addition, in the case of a display telephone B that can display a dial number, the telephone B itself should not output an ID code dialing signal, and the main device A should not send the ID code to the telephone B. Phone B
It is possible to prevent the ID code from being displayed. Further, in the above embodiment, the judgment circuit 7 is configured to judge the dial number, but the same function can be realized by providing this judgment function to the software of the microconverter itself in the control circuit 4. Can be done.

Effects of the Invention As described above, according to the present invention, when the dialed number from the telephone is detected and it is determined that there is a need to send the ID code, the registered ID code is sent to the specified dialing position. Since the ID code can be automatically added to the telephone number and sent out by dialing, it is possible to prevent the ID code from being known to the telephone user in dialing functions (line services) that require the sending of the ID code. Further, since the operator 9/- can omit the dial operation for the ■D code, the dial operation can be easily performed.
