Abstract

PURPOSE:To attain a management for a tariff by an individual unit, by collating an inputted password number to a memory circuit, issuing permission for originating call trunk line only when collation is completed, and outputting an address corresponding to the password number to a tariff managing device. CONSTITUTION:At the time of using push-button telephone sets 2a-2n by the user of a telephone, the password allocated to each individual is inputted first to the push-button telephone set, and following that, a prescribed telephone number is inputted. Thereby, a central processing unit 9 collates the personal identification number with a memory circuit 13, and outputs a permission signal to an input-output interface 7 only when a corresponding personal identification number exists. A switch circuit network 4 is operated by the output, and a corresponding push-button telephone set is connected to a trunk line 1 through a sound circuit line 6, and a sound interface circuit 5, then a call is permitted. In this way, by setting the personal identification number different for each individual, it is possible to prevent the telephone from being used by a third party, and also, to perform the management of the tariff by each individual.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a button telephone device having a charge management function,
In particular, the present invention relates to a key telephone device that allows charge management for individuals.

[Conventional technology]

Conventionally, when a large number of telephones are installed relative to the number of telephone office lines, a main device is installed between the plurality of button telephones and the telephone office lines to switch the telephone lines. and,
In this type of telephone system, when managing charges for each of multiple key telephones, a charge management device is installed in the main unit, and the charge management device calculates the frequency of use of each key telephone. Manages telephone charges.

[Problem that the invention seeks to solve]

In the above-mentioned telephone charge management system, charge management is performed for telephones, and therefore charge management for each person using the telephone is not possible. Therefore, when managing charges for individuals, it is necessary to allocate a telephone to each individual for exclusive use, and an unnecessarily large number of telephones must be installed. Furthermore, even if this is done, it is difficult to perform accurate charge management, as each individual does not necessarily use only the specified telephone, and the telephone may also be used by a third party.

[Means for solving problems]

The button telephone device of the present invention solves the above problems and enables charge management on an individual basis.

The button telephone device of the present invention includes: a charge management device that is built into a main device and manages charges in units of preset addresses; and a memory circuit that stores addresses of the charge management device in correspondence with recited numbers. The system is equipped with a central processing unit that verifies the input PIN number against a memory circuit, permits station line calling only when the PIN code is verified, and outputs the address corresponding to the PIN number to the charge management device.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

The figure is a block circuit diagram showing the overall configuration of an embodiment of the present invention. In the figure, a plurality of office lines 1 are connected via a main device 20 to a plurality of key telephones 2a to 2n.

That is, this main device 20 is equipped with a central office line accommodation circuit 3 having a function of detecting polarity reversal of the central office line 1, a switch circuit network 4 for switching audio circuits, and an audio interface circuit 5 for supplying direct current. The plurality of office lines 1 are connected to the office line accommodating circuit 3 and then to each matrix column of the switch circuit network 3, and further from the audio interface circuit 5 to each of the button telephones 2a to 2 through the audio circuit line 6. 2n respectively.

Further, the subject ff20 is provided with an input/output interface circuit 7 connected to the central office line accommodation circuit 3 and the switch circuit network 4. This person output interface circuit 7
is connected to a charge management device 8 and a central processing unit 9, and is further connected to a data interface circuit 10 and a data circuit line 11.
It is connected to the plurality of button telephones 2a to 2n via.

The charge management device 8 is configured to calculate telephone charges corresponding to a plurality of preset addresses and add up the charges. This address corresponds to a password number to be described later, and is further set for each individual using the telephone.

A read-only memory 12 and a memory circuit 13 are connected to the central processing unit 9. The read-only memory 12 stores a program for operating the central processing bag W9, and the memory circuit 13 stores a plurality of different recitation numbers corresponding to each individual and addresses corresponding thereto, as described above. ing.

Further, the central processing unit 9 is configured to control the key telephones i2a to
2n to data circuit line 11. The code number input through the data interface circuit 10 and the input/output interface 7 is checked against the memory circuit 13, and only when the code is checked, a signal is output to the switch circuit network 4 through the input/output interface 7 to permit central line transmission. At the same time, the address corresponding to this code number can be output from the memory circuit 13 to the fee management device 8.

According to the above configuration, the telephone user can use the button telephones 2a to
When using 2n, a person first inputs a code number assigned to each individual using a key telephone, and then inputs a predetermined telephone number.

Then, the recited number is transferred to the data circuit line 11. The data is input to the central processing unit 9 through the data interface circuit 10 and the input/output interface 7.

The central processing bag W9 compares this recitation number with the memory circuit 13, and outputs a permission signal to the input/output interface 7 only when a corresponding recitation number exists. The switch circuit w44 is operated by this output, and the corresponding button telephone is connected to the office line 1 via the voice circuit line 6 and the voice interface circuit 5, thereby enabling a telephone conversation.

At the same time, the central processing unit 9 retrieves the address corresponding to the recited number from the memory circuit 13 and outputs this address to the fee management device 8 through the input/output interface 7. As a result, the fee management device 8
Waits for a polarity inversion signal from , and calculates and totals charges for the corresponding address.

Therefore, with this device, it is possible to make a telephone call using a code number, and to manage charges on a per code number basis. Therefore, by setting a different code number for each individual, it is possible to prevent third parties from using the telephone and to manage charges on an individual basis.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and in particular, various modifications can be made to the configuration of the main device.

〔Effect of the invention〕

As explained above, the present invention verifies a preset PIN number, enables a call using a telephone circuit when the PIN number is verified, and manages charges for each PIN number by using an address corresponding to the PIN number. Because of this structure, 1-meter talk is only possible when the code number is verified, which prevents people outside the group from using the phone, and at the same time allows charge management for each code number, that is, for each individual. This makes it possible to effectively manage telephone calls and their charges.
