Abstract

PURPOSE:To set control information stored in advance and to preclude the possibility of the illegal rewrite of control information by selecting a partial setting of control information of a layer allowed by command entry and transfer from a setting memory. CONSTITUTION:When a command reply signal is confirmed in a public telephone set 1 and a test switch 20 is operated, the public telephone set 1 reaches the test mode and when a dial key 21 is inputted, a transmission request command of a security code is sent to an operation setting device 30 via a transmission terminal TX and the telephone set awaits the call reception. On the other hand, the operation setting device 30 receiving the transmission request command sends a security code stored in an EEPROM 34 or an EEPROM 35 to the public telephone set 1 to await the call reception. Then the received security code is collated by the public telephone set 1 and when a predetermined password is entered by operating the dial key 21, the control information setting is made available. Thus, illegal setting of the control information is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a public telephone set for setting control information such as call time and call charges.

[Prior Art] In conventional public telephones, various control information such as call charges, call time, toll-free numbers, and prohibited dial numbers are stored in read-only memory (ROM) in advance. Call services are controlled based on this control information.

[Problems to be Solved by the Invention] The above-mentioned conventional public railway telephones do not allow maintenance personnel to change various control information at the installation location, and other control information, such as management number, calendar clock information, dial type, etc. Settings could not be changed at the installation location either.

Therefore, when changing and setting these control information, even a slight change requires replacing the ROM at the installation location, resulting in a problem of unnecessary expense. Furthermore, the control information set for each public telephone is often different, and the management of the ROM from manufacture to installation is extremely troublesome.

In order to solve this problem, if the installer or maintenance person were to be able to change the control information by operating the dial keys of the public telephone at the installation site, there would be a risk that the maintenance person or the like could make unauthorized settings. There is. Under these circumstances, in other countries, there has been a demand for the development of public telephones in which the control information will not be set incorrectly even if a maintenance person or the like operates the dial keys to change the control information.

[Means for Solving the Problems] In order to solve such problems, the first invention of the public telephone according to the present invention provides a control information setting system having a setting memory having the same data area as the control memory. A device, a connection means for connecting this control information setting device to a public telephone, an analysis means for analyzing a command input from a dial key when the control information setting device is connected by this connection means, and an analysis of this analysis means. The apparatus is provided with a control means that selectively causes the control memory to selectively perform a partial setting operation and a transfer operation of the control information of the hierarchy permitted by the dial key to the control memory according to the result.

Further, in a second aspect of the invention, when the control information setting device is not connected, the control means only performs the setting operation of the control information at the lowest level of the hierarchy according to the analysis result of the analysis means.

In a third aspect of the invention, the control information storage device is fixedly provided with a first setting memory and also includes memory connection means to which a second setting memory can be attached.

Further, in a fourth aspect of the invention, the control means determines a corresponding setting mode based on both the presence or absence of the second setting memory and the analysis result of the analysis means, and provides a portion of the control information according to the setting mode. It is designed to perform setting operations and transfer operations.

Further, in a fifth invention, the control means reversely transfers the control information in the control memory to the setting memory in accordance with the analysis result of the analysis means.

Further, the sixth invention provides for reversely transferring the control information of the control memory to one of the setting memories according to the output of the analysis means only when the second setting memory is installed in the control information setting device. It was designed to do so.

[Function] When a control information setting device is connected, when a command is input from the dial key, the partial setting operation and transfer operation of the control information of the layer permitted by this command input from the setting memory are selectively performed. It will be done.

Further, when the control information setting device is not connected, only the setting operation of the control information at the lowest level of the hierarchy is performed according to the analysis result of the analysis means.

Further, the second setting memory is removably attached to the control information storage device.

Further, a corresponding setting mode is determined based on both the presence or absence of the second setting memory and the analysis result of the analysis means, and a partial setting operation and a transfer operation of control information are performed according to this setting mode.

Further, the control information in the control memory is reversely transferred to the setting memory in accordance with the analysis result of the analysis means.

Further, only when the second setting memory is installed in the control information setting device, the control information in the control memory is reversely transferred to one of the setting memories in accordance with the output of the analysis means.

Next, the second factor is a front view of the operation setting device 30. In the figure, 36 is a connector for connection to the public telephone 1. The inside of this connector 36 is composed of four wires, two of which are 5V power supply lines supplied from the public telephone 1, and the other two wires are a transmission terminal TX and a reception terminal RX between the CPU 2 and CPU 31, respectively. This is a transmission line for transmitting control information as serial data. Further, the EEPROM 35 is removable.

Note that each of the EEPROMs 5, 34 and 35 has the same data area, that is, the same capacity.

Transfer and store it inside.

Then, in step 135, it is determined whether on-hook has occurred, and if the answer is "N", the process returns to step 130, and if "Y"
If , that is, on-hook, on-hook processing is performed in step 136 and the process ends.

Further, if the result in step 132 is "N", that is, if it is not a medium level setting command, it is determined in step 140 whether it is a low level setting command, and if this is "N", the process returns to step 120, and if "Y" That is, if it is a low-level setting command, low-level control information is set by operating the dial key 21 in step 141 and stored in the EEPROM 5, and the processing from step 135 onwards is executed.

If "N" is determined in step 111, that is, if the operation setting device 30 is not connected, a password input display is performed in step 150, and then in step 15
In step 1, it is determined whether key human resources are available, and this is "N".
If , wait until the key power is available, and if ``Y'', that is, if there is key power, it is determined in step 152 that it matches the PIN number, and if ``N'', the process returns to step 107, and if ``Y'' is If so, a low level setting process is performed in step 153. This low level setting process will be explained in detail in the flowchart of FIG.

If it is determined in step 110 that "rN", that is, it is not a setting command, a test is performed in step 160, and it is determined in step 161 whether on-hook has occurred. And if this is "N", step 1
Returning to step 07, if "Y", that is, on-hook, on-hook processing is performed in step 136.

Further, if "rN" in step 106, that is, if there is no operation of the test switch, it is determined in step 170 whether on-hook has been established, and if "N", dialing is made in step 171.

Telephone control processing such as call processing and billing processing is performed, and the process returns to step 106. When "Y" is determined in step 170, that is, when on-hook, processing from step 136 onwards is performed.

Next, FIG. 4 is a flowchart illustrating details of the low level setting process. First, in step 200, a low-level setting mode is displayed on the LCD display #r22, and then in step 201, it is determined whether there is key power.When "N" is determined in step 201, that is, if there is no key power, key power is If it is "Y", that is, if there is key data, it is determined in step 202 whether this key data is a low-level setting command, and if "N", the process returns to step 200 and "Y"'', that is, if it is a low-level setting command, it is determined in step 203 whether setting contents have been input by operating the dial key 21.

If "N" in step 203, wait until the settings are input; if r Y J, that is, if the settings are input, control information is set in the EEPROM 5 in step 204, and on-hook is activated in step 205. If the judgment is "N" in step 205, the process returns to step 200, and if "Y", that is, on-hook, on-hook processing is performed in step 206 and the process ends.

Next, FIG. 5 is a flowchart illustrating details of the high level setting process. First, in step 300, a high-level setting mode is displayed on the liquid crystal display circuit 22, and then in step 301, it is determined whether there is manual key power by operating the dial key 21, and if this is "N", it is determined that there is no key input. If the waiting state is "Y", that is, if a setting command is input, it is determined in step 302 whether this setting command is a high-level setting command.

When step 302 is "Y", that is, if it is a high-level setting command, it is determined in step 303 whether it is a batch data setting command, and when this is "Y", in step 304, operation setting data is read, that is, operation setting. The high-level f/lI control information stored in the EEPROM 35 in the device 30 is read, and in step 305 a setting process is performed, that is, this control information is transferred to the EEPROM 5 in the public telephone 1 and stored therein. Then, in step 306, on-hook is determined, and if "N", the process returns to step 300, and if "Y", that is, on-hook, an on-hook process is performed in step 307, and the process ends.

If the result in step 303 is "N", that is, if the command is not a bulk data setting command, it is determined in step 310 whether the setting contents have been input by operating the dial key 21, and if the result is "N", the system waits until the input is made. , "Y", that is, if it is input, high-level setting processing is performed in step 311 and stored in the EEFROM 5, and processing from step 306 onwards is executed. Also, step 302

As explained above, the setting of the control information of the public telephone according to the present invention can be transferred from each setting mode at the middle level and the high level to the setting mode at a lower level.

In this embodiment, the control information is stored in the EEPROM5.
34 and 35, but the configuration is not limited to this, and any memory that can be read and written, such as a backed-up RAM, may be used. Therefore, the operation setting device 30 may be powered by a battery. You may do so.

[Effects of the Invention] As is clear from the above explanation, when a command is input from the dial key when the control information setting device is connected, the public telephone according to the present invention is authorized by this command input. Since the configuration is configured to selectively perform partial setting of control information in the layered layer and transfer from the setting memory, only the maintenance person who owns the control information setting device can read the control information stored in advance in this control information setting device. This has the effect that information can be set in public telephones and there is no fear of unauthorized rewriting of control information.

In addition, when the @control information setting device is not connected, the configuration is configured so that only the setting operation of the control information at the lowest level of the hierarchy is performed according to the analysis result of the analysis means, so even if there is no control information setting device, the control information can be set. This has the effect of allowing you to do this.

In addition, since the second setting memory is removably attached to the control information storage device, if the setting of higher-level control information is no longer necessary, the second setting memory is also unnecessary and the control information can be controlled. This has the advantage that the information storage device can be constructed at low cost.

Further, the corresponding setting mode is determined based on both the presence or absence of the second setting memory and the analysis result of the analysis means,
Since the configuration is configured to perform the partial setting operation and transfer operation of the control information according to the setting mode, there is an effect that the control information can be set according to the hierarchy.

In addition, the control information in the control memory is reversely transferred to the setting memory according to the analysis result of the analysis means, so
If other public telephones require the same control information,
The control information storage device storing this reverse-transferred control information can be connected to another public telephone and copied.
This has the effect of eliminating the need for manual setting operations.

Further, the control information of the IIJgl memory is configured to be reversely transferred to one of the setting memories according to the output of the analysis means only when the second setting memory is installed in the control information setting device. This has the advantage that the setting memory for copying the control information can be selected.
