Abstract

PURPOSE:To automatically display and confirm the time of an opposite country at any time, by using a country number and time difference response memory device which stores a time difference with a country shown as a country number used in an international direct distance dialing, and a telephone set with a time indicator possible to display a time and date. CONSTITUTION:When a user off-hooks a telephone set 1 with a time indicator and dials the specific number and the country number of the opposite country of the international direct distance dialing, a central controller 3 detects and retrieves it. And if the country number which coincides with the number exists, the controller takes out the time difference corresponding to the country number. Furthermore, the controller takes out the values of a present date and a present time from a timepiece device 4, and finds the present date and time of the opposite country of the international direct distance dialing designated by the user by adding taken out time differences, and issues instruction to display those to the telephone set 1 with the time indicator. Thereby, the date and the time at a present time of the opposite country of the international direct distance dialing designated by the user are displayed on the time indicator of the telephone set 1 with the time indicator.

[Detailed Description of the Invention] Industrial Field of Application The present invention is capable of making a telephone call to a destination country by directly dialing a number specifying the destination country and the telephone number of the destination country without going through an operator. This invention relates to an electronic switchboard capable of so-called international landmark calls.

BACKGROUND ART FIG. 2 shows the configuration of a conventional electronic exchange. The configuration of this conventional example will be explained below (as shown in FIG. 2. The communication path switch 2 (=connected) is configured to be controlled by the central control device 3 (2). The central control device 3 also controls the communication path switch 2. 4 is a clock device. Yes, and connected to the central control unit 3.

Once the date and time values have been set for the clock device 4, other devices are turned off and the clock device 4 stops operating (even if there are two).
It is a device that continues to operate and automatically advances the date and time values and always maintains the current date and time values.

Next (2) Operation of the above conventional example (explained in two parts.Telephone 1
When the C channel switch 2 (2) is connected, the central control device 3 detects this, retrieves the current date and time values from the clock device 4, and sends them to the telephone 1 connected to the new C dual channel switch 2. and instructs the clock display to display the retrieved date and time values.The clock display of phone 1 independently displays the given date and time values until phone 1 stops working. If you want to check the time in the other party's country for an international white call, use & look at the date and time values shown on the clock display of this phone 1, and manually add the time difference between the two parties. This allows you to recognize the time in the other country.

Problems to be Solved by the Invention However, in the above conventional example, if the user wants to check the time in the other country of the international Shirabu Menzume, it is necessary for the user to be fully aware of the time difference with the other country. The problem was that each calculation had to be made based on the time difference.

The present invention solves these conventional problems, and when a user wants to check the time in the other party's country for an international white call, the user can dial the country code of the other country and automatically check the time at any time. The purpose of this is to enable users to display and confirm the time in the other country.

Means for Solving the Problems In order to achieve the above object, the present invention provides a country code/time difference compatible memory that stores the country code used in international white calls and the time difference between the country indicated by the country code. If you want to check the time in the other party's country for an international white call using a device and a telephone with a clock display that can display the time and date, you can check the time in the other country by dialing the country code of the other country. It is configured so that the current time is immediately displayed.

Therefore, according to the present invention, the country code/time difference compatible memory device (- is the country code used when making an international white call and the time difference between the country indicated by the country code and the time difference between the country code and the country indicated by the country code is stored. When checking the time in the other country of a Shirabe call, the user can specify the country code of the other country and use the country code/time difference compatible memory device to determine the time difference between the country and the specified country. By displaying the date and time by adding the requested time difference to the current time on a telephone equipped with a clock display that can display the time, the user can check the time in the other party's country for an international white call. It has the effect of being able to recognize the time without knowing the time difference with the other country, or without calculating the time yourself from the time difference.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 2, reference numeral 1 denotes a telephone, which has a clock display capable of displaying time and date.

The telephone set 1 is connected to a call path switch 2 and is configured to be controlled by a central control unit 3. The central controller 3 also controls the communication path switch 2.

4 is a clock device, 5 is a memory device corresponding to the country code and time difference, and each is connected to the central control device 3 (two are connected to each other; the clock device 4
Once you set the date and time values, it will continue to operate even if other devices are turned off and stopped, automatically advancing the date and time values so that the current date is always displayed. - Configured to hold time values. The country code/time difference compatible memory device 5 stores the time difference between the country code used to determine the other party's country during an international call and the country indicated by the country code (- if there are multiple time differences in the country). It combines a country code with an area code used to designate a certain region within that country, and stores the corresponding time difference.

Next, the operation of the above embodiment will be explained in two parts. In the above embodiment, the user takes off-hook the telephone 1 with a clock display, and selects the special number for checking the time of the destination country for an international white call and the country code of the destination country. When you dial , the central control device 3 detects this and stores all digits of the country code of the destination country.From the country code stored in the country code and time difference compatible memory device 5, select a country that matches the stored country code. The central control device 3 searches to see if the number exists, and if a matching country code exists, takes the time difference stored in correspondence with the country code.The central control device 3 also searches the clock device 4. By extracting the current date and time from , and adding the time difference retrieved from the country code/time difference compatible memory device 5 to this value, the current date and time of the destination country of the international white call specified by the user is determined. and instruct the telephone with a clock display 1 (2) to display this, and display the clock display of the telephone 1 with a clock display (
: Displays the current date and time of the destination country of the international Shirabu call specified by the user.

In this way, according to the above embodiment, if you want to check the date and time of the other party's country for an international white call, you can specify the country code of the other country from your telephone and immediately ( It has the advantage that the date and time can be displayed, and the time can be easily recognized by the display on the clock display (-).

Effects of the Invention As is clear from the above embodiments, the present invention has the following two effects.

(1) Even if the user does not know the time difference with the other country of the International Hakubu Rensho, if the user specifies the country code (including the area code) required for the international Hakubu call, the user will be able to know it immediately from the telephone. Is possible.

(2) Even if the user has a time difference table, it is faster than calculating the time by looking at the table and is accurate (
= It is possible to know the date and time of the other party's international Hakubu call.

(3) You can display and check the current time and date of the recipient country before sending an international notification, so you can avoid situations such as accidentally making a late-night call to the recipient overseas and causing trouble. This has the advantage that it can be prevented.
