Abstract

PURPOSE:To allow a user of a telephone line to confirm when, where and how long a telephone call is made and how much telephone tariff is expected by detecting the polarity inversion of the telephone line. CONSTITUTION:When a called party replies (off-hook) in an NTT line, the polarity of the DC level at the caller is inverted and when the called party or the caller hooks on its handset, the polarity of the DC line is restored. Then the caller uses an input key 2 to select out a telephone number of the called party in a data storage device 1 and a network controller(NCU) 3 applies automatic dialing. The hook-off of the called party is detected by a polarity inversion detector 3-2 of the NCU 3, a timer 4-1 of a counter 4 is started and when the hook-on state is reached, the timer 4-1 is similarly stopped and a talking time is obtained. Thus, the user of a telephone network immediately recognizes the telephone tariff, number of times of use and a place to which a phone call is made.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] This invention relates to a dial device having a data storage device, an input key device, an NCU, a timing device, a calculation device, and an optical display device.

[Conventional technology 1] With the enforcement of the Telecommunications Business Law in April 1985, telecommunications businesses and the installation of terminal equipment were liberalized, and various manufacturers began selling intelligent telephones with various functions such as auto-dial. However, with the exception of telephones for which you have to pay a fee, such as public telephones, telephone users must
There is no way to know the cost of a call until you receive a bill from NTT.

[Problem to be solved by the invention] It is uneasy not to know the telephone usage charges immediately, and even if the bill is requested later, the usage time, place of telephone calls, number of calls, etc. must be clearly stated on the bill. Since it is not done, the user does not know. Even if the user measures the usage time and calculates the fee, there are problems such as the fee varies depending on day and night and distance, and a great deal of effort is required. The present invention is intended to solve these problems, and its purpose is to provide a device that allows telephone network users to easily check call charges, number of calls, place of call, etc. It is in.

C Means for Solving Problems j The dial device of the present invention has a data storage device, an input key device, an NCU, a clock device, a calculation device, and an optical display device, and the data storage device has a telephone number , the input key device has a memory for storing standard data of telephone charges based on usage time zone, usage time, distance, and data from other devices; the NCU has at least a telephone network polarity reversal detection device and a selection signal sending device for sending out a telephone number in the data storage device as a dialing signal; the clocking device has a control input device; The calculation device has a timer that starts and stops according to a signal from the computer and a clock that measures the time.
The optical display device is characterized in that it has a calculation device for calculating the charge for one call from the data of one device, and the optical display device has a display device for displaying data from other devices.

[Operation I] On an NTT line, when the called party answers (off-hook), the DC polarity of the outgoing call is reversed. Thereafter, when the called party or the calling party hangs up the telephone (on-hook), the DC polarity returns to its original state. According to the above configuration of the present invention, the calling party selects the called party's telephone number in the data storage device using the input key device, and auto-dials it by the NCU. The off-hook state of the called party is detected by the polarity reversal detection device of the NCU, and the timer of the clock device is started. When the on-footer condition occurs, stop the timer in the same way,
Call time is required. The call charge can be determined based on the call time, clock data from the timer, and data from the data storage device.

[Embodiment 1 FIG. 1 is a block diagram in an embodiment of the present invention,
1 is the data record '1'! 2 is an input key device, 3 is an NCU, and 3-1.3-2 is a selection signal sending device and a polarity reversal detecting device, which are located in each of the three NCUs. 4 is
Timing devices 4-1 and 4-2 are timers and clocks located in the timing devices of 4, respectively. 5 is a computing device, 6 is an optical display device (in this embodiment, a liquid crystal display is used), and 7 is a telephone line connection terminal. 8 to 12 are input data and control signals from the large oyster device to other devices. 13 is a signal output when the polarity reversal detection device 3-2 detects a change in the DC polarity of the telephone line.

14 is a signal line for receiving and passing data between each device. The operation will be explained below.

Data record-1! The device 1 stores reference data for call charges based on telephone number, time of use, time of use, and distance. This data can be input from the input key device 2,
Possible changes include transferring data from another device or replacing part of the memory in the data storage device. This data storage device also stores data from other devices. For example, the calculation result of the calculation device 5 and the number of calls from the signal 8 from the input key device are also stored. When operating this device as a caller, the caller operates the input key device, operates the selection signal transmitter by signal 12, and performs an off-hook and dial call. At this time, it is possible to send the telephone number directly from the input key device to the selection signal transmitting device, or to send the telephone number in the data storage device to the selection signal transmitting device by using the input key device. When the receiving side goes off-hook, the direct current polarity on the calling side of the telephone line is reversed, which is detected by the polarity reversal detection device 3-2, and the timer 4-1 is started by the signal 13. Furthermore, if the receiving side does not respond, it is also possible to go on-hook using signal I2. After the receiving side goes off-hook, when the transmitting side or the receiving side goes on-hook, the DC polarity on the transmitting side returns to the original. The polarity reversal detection device 3-2 detects this, and the timer 4-1 is stopped by the signal 13. The signal 13 is also sent to the clock 4-2, and the clock 4-2 stores the current time in the data storage device as the call use time. Instead of timer 4-1,
It is also possible to utilize the difference in off-hook and on-hook times determined by the clock 4-2.

The calculation device 5 calculates the call charge based on the value of the timer 4-1 (communication time), the value of the clock 4-2 (use time period), and the data in the data storage device 1. This calculated data can also be displayed on the optical display device 6 during one call. These data are also stored in the data storage device via signal 14.

The optical display device is activated by the signal 9 from the input key device 2.
Data of other devices and device status can be displayed.

[Effects of the Invention] What has been described above is one embodiment of the present invention.According to the present invention, by detecting the polarity reversal of the IT telephone line, it is possible to determine when, where, and for how long the call was made, and how much the call cost. This has the effect of allowing the telephone line user to check whether a call has been made or not.
