Abstract

PURPOSE:To provide a private branch exchange which can perform the ID transmission by an ID card through a single telephone set. CONSTITUTION:When an ID code is read out of the ID card put into a card reader 11, a central controller 10 actuates a DC loop circuit 12 to form a DC loop to a private branch exchange (not shown in the diagram). Then the controller 10 transmits an extension outgoing special number to the private branch exchange and converts the ID code read by the reader 11 into an outgoing ID to send this to the private branch exchange. Thus a DC loop is formed between a single telephone set (not shown in the diagram) and the private branch exchange. Under such conditions, the operation of the circuit 12 is stopped. The private branch exchange permits the extension outgoing received from the single telephone set as long as the outgoing ID supplied from an interface device 9 is registered.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange having a function of transmitting an outside line (ID transmission) from a terminal telephone using an ID card, and more particularly to a structure for making the ID transmission using a single telephone.

[0002]

2. Description of the Related Art In a recent private branch exchange, identification information (hereinafter referred to as a transmission ID) for exclusive use of an outside line is registered for each user, and the transmission is registered from a telephone of a terminal which reads an ID card. Some have a function of accepting an outside line call from the telephone when the ID is input. Therefore, private branch exchanges equipped with such functions
A dedicated telephone having a function of reading an ID card (hereinafter referred to as a telephone with an ID card reader) must be connected as a terminal. When making an ID call from this telephone with an ID card reader, the sender is the ID
By reading the ID card into this telephone using a card reader, the telephone transmits the ID code recorded in the ID card and the call request to the private branch exchange. When the private branch exchange receives the ID code and the call origination request, the private branch exchange is put into a state of accepting an outside line call from the telephone only when the call origination ID corresponding to the ID code is registered. After that, an outside line is transmitted from the telephone with the ID card reader through the private branch exchange.

By the way, when the conventional private branch exchange is used to make an ID call using a single telephone, the caller dials the outside telephone line special number after off-hooking the single telephone, and then dials the outgoing call ID. As a result, the private branch exchange is brought into a state of accepting an outside line call from the single telephone when the dialed call ID is registered inside. However, in a conventional private branch exchange, a telephone with an ID card reader as described above is required to make an outside line using an ID card, and a conventional single telephone (cordless telephone, answering machine, etc.) cannot be used for an ID card. There was a drawback that you couldn't make an outside call.

[0004]

As described above, a telephone with an ID card reader is required to perform ID transmission using an ID card by the conventional private branch exchange, and the ID transmission using the ID card is performed from a single telephone. Therefore, there is a drawback that it is uneconomical because it is necessary to replace the single telephone with a telephone with an ID card reader.

Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks and to provide a private branch exchange capable of transmitting an ID by an ID card using a single telephone.

[0006]

SUMMARY OF THE INVENTION The present invention has a private branch exchange having a single telephone as a terminal and having a function of permitting an outside call from the terminal only when correct calling identification information is input from the terminal. A card reader for reading the identification code recorded in the identification card, a conversion means for converting the identification code read from the identification card by the card reader into corresponding outgoing identification information, and the identification by the card reader. Immediately after the identification code in the card is read, a direct current loop forming circuit that forms a direct current loop with the private branch exchange, and after the direct current loop is formed by this direct current loop forming circuit, predetermined external line transmission information To a private branch exchange, and after the predetermined outside line transmission information is transmitted by the first transmission means, Second transmitting means for continuously transmitting the originating identification information obtained by the converting means to the private branch exchange; and, after the originating identification information is transmitted to the private branch exchange by the second transmitting means, the DC loop is formed. An interface device including a control means for opening a DC loop formed by a circuit is inserted between the single telephone and the private branch exchange.

[0007]

In the private branch exchange of the present invention, the card reader of the interface device inserted between the single telephone and the private branch exchange reads the identification code recorded in the identification card. The conversion means converts the identification code read from the identification card by the card reader into corresponding transmission identification information. The DC loop forming circuit forms a DC loop with the private branch exchange immediately after the identification code in the identification card is read by the card reader. The first transmitting means transmits predetermined outside line transmission information to the private branch exchange after the DC loop is formed by the DC loop forming circuit. After the predetermined outside line transmission information is transmitted by the first transmission means, the second transmission means continuously transmits the transmission identification information obtained by the conversion means to the private branch exchange. The control means opens the DC loop formed by the DC loop forming circuit after the transmission identification information is transmitted to the private branch exchange by the second transmitting means. As a result, the private branch exchange receives the same information as the outside line transmission by the identification information using the single telephone, so that the outside line transmission from the single telephone can be performed by using the identification card.
