Abstract

PURPOSE:To easily release calling origination connection restrictions. CONSTITUTION:An operator loads a magnetic card 3 in the card reader 21 of a telephone terminal 2. The card reader 21 reads the ID card out of the magnetic card 3 and transfers it to a telephone exchange 1. A controller 13 receives the ID code, sent from the telephone terminal 2, through a line circuit 11 and decides whether it is previously registered in a main storage device 14. Then when the ID card is registered yet, the calling connection restrictions set for the telephone terminal 2 are released. Consequently, the telephone terminal 2 is enabled to call and the operator dials the number of an calling destination. The controller 13 receives the number through the line circuit 11 and performs calling connection processing. Then the telephone terminal 2 is connected to the calling destination and after the telephone call ends, the controller 13 sets calling connection restrictions of the telephone terminal 2 newly.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange system comprising a telephone exchange and a telephone terminal whose outgoing connection is restricted.

[0002]

2. Description of the Related Art Conventionally, in a telephone exchange system including a telephone exchange and a telephone terminal connected to the telephone exchange and the outgoing connection is restricted by the telephone exchange, the outgoing connection restriction of the telephone terminal is released and When making a call from the telephone terminal, the operator dials the special number and the ID code from the telephone terminal, and the telephone exchange receives the information and releases the outgoing call connection restriction of the telephone terminal, and the outgoing call from the telephone terminal is possible. I was trying.

[0003]

As described above, in the conventional telephone exchange system, in order to release the outgoing call connection restriction, it is necessary to perform a troublesome operation of dialing the special number and the ID code from the telephone terminal. There wasn't. Further, the operator has to store the special number and the ID code.

An object of the present invention is to eliminate such drawbacks and to provide a telephone exchange system in which an outgoing call connection restriction can be released by a simple operation and an operator does not need to store an ID code or the like. It is in.

DISCLOSURE OF THE INVENTION According to the present invention, in a telephone exchange system comprising a telephone exchange and a telephone terminal connected to the telephone exchange and the outgoing connection being restricted by the telephone exchange, the restriction of outgoing connection is released. A magnetic card on which predetermined information for magnetic recording is magnetically recorded, and a magnetic card reading means provided on the telephone terminal for reading the predetermined information from the magnetic card and sending the read information to the telephone exchange. And the telephone exchange comprises:
When the predetermined information is received from the telephone terminal, restriction releasing means for canceling the outgoing connection restriction of the telephone terminal,
After the restriction releasing means releases the outgoing connection restriction, the restriction setting means sets the outgoing connection restriction of the telephone terminal under a predetermined condition.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 shows an example of a telephone exchange system according to the present invention. Reference numeral 1 is an automatic telephone exchange, and 2 is a telephone terminal connected to this telephone exchange. Reference numeral 3 is a magnetic card on which an ID code for canceling the outgoing connection restriction is magnetically recorded. The telephone terminal 2 is equipped with a magnetic card reader 21, and when the magnetic card 3 is attached to the magnetic card reader 21, the above-mentioned ID code is read from the magnetic card 3 and the read ID code is sent to the telephone exchange 1.

In the telephone exchange 1, 12 is a switch frame, and 15 is a line trunk connected to this switch frame. Reference numeral 11 is a line circuit that connects the switch frame 12 and the telephone terminal 2, and reference numeral 13 is a control device that controls the switch frame 12. The control device 13 is also connected to the telephone terminal 2 through the line circuit 11, and releases and sets the outgoing call connection restriction based on the information stored in the main storage device 14. Main memory 14
Stores various control information and an ID code for releasing the outgoing connection restriction.

Next, the operation will be described. It should be noted that the call connection regulation is set for the telephone terminal 2, and the regulation is lifted to make a call from the telephone terminal 2. The operator first attaches the magnetic card 3 to the card reader 21 of the telephone terminal 2. When the magnetic card 3 is attached to the card reader 21,
Read the ID code magnetically recorded there,
Transfer it to the telephone exchange 1.

In the telephone exchange 1, the control device 13 receives the ID code sent from the telephone terminal 2 through the line circuit 11 and determines whether or not the ID code is a pre-registered ID code in the main storage device 14. To do. When the control device 13 determines that the ID code is the registered ID code, the control device 13 releases the outgoing call connection restriction set for the telephone terminal 2.

As a result, the call can be made from the telephone terminal 2, and the operator dials the number of the callee. The controller 13 receives this number through the line circuit 11,
Perform outgoing connection processing. Then, when the telephone terminal 2 is connected to the call destination and then the call ends, the control device 13 sets the outgoing call connection restriction of the telephone terminal 2 again.

Further, if the control device 13 determines that the ID code is registered and releases the outgoing connection restriction of the telephone terminal 2, if the number is not dialed by the telephone terminal 2 within a fixed time, The cancellation of the outgoing call connection restriction is canceled and the outgoing call connection restriction for the telephone terminal 2 is reset.

[0012]

As described above, in the telephone exchange system according to the present invention, the magnetic card is used as the I
The information such as the D code is read, the telephone exchange receives the information, and when the information is the registered predetermined information, the outgoing connection regulation set for the telephone terminal is released. Therefore, in the telephone exchange system according to the present invention, it is not necessary to dial the special number and the ID code as in the conventional case, and the outgoing call connection restriction can be released by simply inputting the magnetic card. The operator does not need to store the ID code as in the conventional case.
Further, when the call ends after the outgoing connection restriction is released, the outgoing connection restriction is automatically set, so that the service class is not affected.
