Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for registering a telephone operator number in an automatic telephone exchange, and particularly to a system for registering a personal operator number different from a telephone number from a telephone set.

Conventionally, as a telephone operator number registration system in an automatic telephone exchange, a system having the configuration shown in FIG. 1 has been used. In the system shown in the figure, under the control of a central control unit 160, a typewriter 190 stores the telephone number and call restriction class of the telephone in correspondence with telephones 100 to 10n via an interface circuit 180 to a telephone operator number registration memory 170. It is configured to register information, etc., and call restriction class information is registered for each operator assigned to a telephone number, centering on the telephone number. Here, for example, if the call restriction class of telephone 100 is Special A and the call restriction class of telephone 101 is B, then it is impossible to make a central line call from telephone 101 having the call restriction class B. However, if the person who owns the telephone 101 is using the telephone 101 that is in the call restriction class
If you use , it is possible to make calls to the central office line.

However, in the conventional registration method, when converting call charges in the above case, the user uses a telephone 10 that has the calling restriction class of Party B.
1, the call charges are added to the telephone set 100 which has the special A call restriction class, so there is a drawback that accurate call charges cannot be calculated. Furthermore, it is impossible to know who is making the call when calling from a telephone installed in a conference room, etc., so there is no other option than to treat it as miscellaneous expenses.

The present invention was made to solve these drawbacks, and includes a magnetic card reading device for each telephone, a memory in the subscriber circuit, and information on the operator number and calling restrictions from each operator's magnetic card. By reading information, etc. and storing these information signals in memory, no matter where the telephone operator moves or which telephone he or she uses to make a call, the call charge will be accurately reported to the operator. The purpose of the present invention is to provide a telephone operator number registration method in which the number is added.

In order to achieve such an object, the present invention provides a magnetic card reading device for reading operator number information, calling restriction information, etc. recorded on a magnetic card for each telephone in an automatic telephone exchange, and the magnetic card reading device. means for frequency modulating the information signal from the subscriber circuit, and means for detecting a communication path empty state for controlling connection of the frequency modulated information signal to the telephone set, and means for frequency demodulating the information signal in the subscriber circuit. , a memory for storing the demodulated information signal, and a communication path empty state detection means for controlling the connection to the means for frequency demodulating the information signal from the telephone set. The device is configured to store and register information, call restriction information, etc. in a memory.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 2 is a block diagram showing an embodiment of the telephone operator number registration system of the present invention, and FIG. 3 is a block diagram showing details of the magnetic card reading/transfer device and subscriber circuit shown in FIG. 2. In these figures, the telephone operator number registration method of the present invention is applied to each telephone 200.
20n, and subscriber circuits 210 to 21n connected to the respective telephones 200 to 20n.

The above magnetic card reading and transferring device 280-28n
As shown in FIG. 3, the magnetic card reader 3
08, a frequency modulation circuit 307, and a communication path empty state detection circuit 301, and if the telephone operator does not set the magnetic card 309 owned by the operator into the magnetic card reader 308, the telephone 300 will not be activated. It is configured so that it cannot be used.

The magnetic card reader 308 reads telephone operator number information, calling restriction information, etc. from the magnetic card 309, and is provided for each telephone.
The magnetic card 309 is, for example, a cash card,
It can be configured as an employee number card similar to a credit card, and the above information is magnetically recorded on it.

The frequency modulation circuit 307 frequency modulates a signal such as operator number information read from the magnetic card 309, and the modulated information signal is transmitted to a transformer via a frequency transmission driver 306 and a break contact 304 of a relay 303. 305.

The communication path empty state detection circuit 301 is connected to the secondary side of the transformer 305, detects the empty state of the communication line, and controls the connection of the information signal from the frequency modulation circuit 307 to the communication line. It is.
That is, when the telephone 300 is in an off-hook state, in a ringing state, or in a howler state, the communication path empty state detection circuit 301 sets the input of the relay driver circuit 302 to a low level to operate the relay 303, and changes the break contact 304 from the closed state. The communication line is changed to the open state, and the transmission of the information signal to the busy telephone line is controlled. Further, when the communication channel empty state detection circuit 301 detects the empty state of the telephone set, it sets the input of the relay driver circuit 302 to a high level to put the relay 303 into the recovery state, holds the break contact 304 in the closed state, and performs transmission control. Under the control of circuit 321, the information signal is controlled to be transferred to the subscriber circuit.

The subscriber circuits 210 to 21n each include a frequency demodulation circuit 313, a memory 314, and a communication line state detection circuit 310, and are automatically activated when the communication line is in an idle state to disconnect the communication line. The contents of the magnetic card 309 set in the magnetic card reader 308 are read through the magnetic card reader 308 and written into the memory 314.

The frequency demodulation circuit 313 demodulates the frequency of the information signal from the frequency modulation circuit 307, which is input via the transformer 319 of the subscriber circuit, the break contact 318, the receiver circuit 311, and the bandpass filter circuit 312. The received information signal is stored in the memory 314 via the serial/parallel data conversion circuit 322 under the control of the reception control circuit 320.

The memory 314 stores information signals from the magnetic card reader 308 provided for each telephone, and the writing is performed by the reception control circuit 3.
20. This reception control circuit 320
is configured so that if the telephone becomes busy before the received data is completely completed, the data is discarded and no writing operation is performed in the memory 314. Note that this memory 31
The contents of 4 can always be read from the central controller 323.

The telephone line status detection circuit 310 is connected to the transformer 319, detects the vacant status of the telephone line, and detects the frequency demodulation circuit 31 of the information signal from the telephone line.
This controls the connection to 3. That is, if the call line is busy (talking, ringing transmission, howler sound transmission in progress), this communication line state detection circuit 310 sets the input of the relay driver circuit 316 to a low level and operates the relay 317, thereby causing the break. When the contact 318 is open and the phone is not busy,
The input of the relay driver circuit 316 is set to high level to restore the relay 317 and break contact 31
8 is in the closed state, and the information signal is sent to the frequency demodulation circuit 3.
13.

In addition, in the registration method of the present invention, a call restriction class is not fixed for each telephone, and information such as the operator number and call restriction is read from the magnetic card and written to the memory of the subscriber circuit. The corresponding operator number and the calling restriction class of that operator are determined. Therefore, each time the phone operator changes, the call restriction class is changed to the call restriction class in the magnetic card owned by the operator.
Further, the registration system of the present invention is configured so that if no magnetic card is set in the magnetic card reader, information indicating that there is no telephone operator is transferred, thereby making it possible to confirm the absence of the operator.

As explained above, the present invention provides a magnetic card reading device for each telephone, a memory in the subscriber circuit, and reads the operator number information, calling restriction information, etc. from the magnetic card of each operator. By configuring these information signals to be stored in memory, the outgoing call restriction class is not fixed to the phone, but can be changed by inserting the magnetic card owned by the user into a magnetic card reader compatible with the phone. Call restrictions and call charges are converted based on the call restriction class information and caller ID information in the magnetic card, so the operator can accurately add charges and make call restrictions no matter which phone he or she uses. When the handler removes the magnetic card from the reader, the absence of the handler can be automatically detected. Furthermore, if the handler is absent and moves to another location, the call transfer function can be automatically performed by inserting the handler's magnetic card into a magnetic card reader compatible with the telephone at the destination. Furthermore, going to work,
It can also satisfy time recorder functions such as leaving records,
This system has various effects different from conventional telephone exchange services, such as being able to call a called party using either a telephone number or a personal number owned by the operator.
