DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone apparatus having a function of managing a date and time.

[0002]

2. Description of the Related Art Many key telephone apparatuses display date and time on, for example, a display of a terminal. In such a key telephone device, the main unit has a calendar unit for managing the date and time, and the calendar unit updates and manages the date and time. Update management of the date and time in the calendar section is performed by counting clocks generated by a clock source such as a built-in crystal oscillator.

[0003] For this reason, when the power is turned off, the date and time are not managed. Therefore, when starting up the system, the user must operate each terminal or a specific terminal to input the current date and time by key. Further, even during the operation of the system, the error of the date and time increases due to the accumulation of the clock error, so that the user must periodically re-enter the correct date and time.

[0004] Generally, the work of inputting these dates and times is as follows.
It is performed in the following procedure. That is, for example, in the case of setting "13:59:00, August 20, 1993", the user first grabs the extension key (INT) and then dials the special key (e.g., # 651) indicating the date setting. Press. Then, in order to input “930820” indicating the date, dial keys “9”, “3”, “0”, “8”
After pressing “2” and “0” in order, press “#” indicating the decision. Further, a special number indicating the time setting (for example, # 65
Press the dial key to enter 2). Then, in order to input “135900” indicating the time, the dial keys “1”, “3”, “5”, “9”, “0”, and “0” are sequentially pressed, and then “#” indicating determination is pressed.

As described above, the work of setting the date and time is troublesome and burdens the user. Also, if there is an input error or no correction is made, the date and time will be incorrect unless the user notices this.

[0006]

As described above, in the conventional key telephone device, the clock generated by itself is counted up with respect to the calendar information and the time information designated by the user, so that the above-mentioned key telephone device is independently operated. Since information is updated and managed, there is a problem that erroneous information is managed unless the user frequently performs complicated setting work for correction.

[0007] The present invention has been made in view of such circumstances, and a purpose thereof is to automatically correct calendar information and time information, thereby always providing accurate calendar information and time information. It is an object of the present invention to provide a key telephone device that can provide time information and can reduce the burden on an operator.

The main controller 16 exchanges control information relating to the extension interface operation.

The identification information detecting circuit 14 is connected to the station line 3. The identification information detection circuit 14 detects and receives identification information given from the network via the station line 3, and supplies the received identification information to the main control unit 16.

The calendar unit 15 performs a time counting operation based on a clock generated by its own clock source, and
It has a well-known configuration for managing date and time information consisting of day, hour, minute and second information. The calendar unit 15 gives date and time information to the main control unit 16. The date and time information can be set by the main control unit 16.

The main control unit 16 controls each unit to realize the exchange operation. The main control unit 16 includes, for example, a microcomputer as a main control circuit, and includes a self-calling processing unit 16a and a calendar correction processing unit 16b in addition to a well-known general control unit in a key telephone apparatus. are doing. Of these, self-call processing means 16
In the process a, a call is made to any one of the outside lines 3 at the time of system initialization after the power is turned on. The calendar correction processing means 16b corrects and sets the date and time information of the calendar unit 15 based on the date and time information included in the identification information received by the identification information detection circuit 14.

FIG. 2 is a functional block diagram showing a specific configuration of the identification information detection circuit 14. The identification information detection circuit 14 includes a modem signal detection unit 21, a data detection unit 22,
It includes a PU 23, an interface unit 24, a serial / parallel conversion unit 25, and a tone detection unit 26.

This embodiment is connected to a network that provides a service called "CLASS" provided in the United States of America. This "CLASS"
In, predetermined identification information is transmitted by superimposing on a ringing signal from a network to a subscriber. As shown in FIG. 3A, the ringing signal is a signal of a predetermined frequency,
This is a signal that is repeatedly turned ON for 1 second across the FF.
A modem signal in which identification information is modulated for 3 seconds, which is an FF, is superimposed. The identification information includes date and time information, a caller identification number, and the like, and has, for example, a format shown in FIG.

The station line 3 is connected to the modem signal detecting section 21, detects a modem signal from signals arriving via the station line 3, and supplies the modem signal to the data detecting section 22 and the serial / parallel converting section 23. .

The data detecting section 22 detects data such as identification information in the modem signal and outputs it to the internal bus 27. The data output from the data detection unit 22 to the internal bus 27 is output to the data highway 17 via the interface unit 25 under the control of the CPU 24.

The serial / parallel converter 23 converts the serial modem signal supplied from the modem signal detector 21 into a parallel signal and outputs it to the internal bus 27. The local line 3 is connected to the tone detecting unit 26, and a predetermined tone signal (for example, 2130 Hz and 2750 Hz tone signals) is detected from signals arriving via the local line 3, and the data detected by the data detecting unit 22. give.

Next, the operation of the key telephone apparatus configured as described above will be described according to the control procedure of the main control unit 16. Since the general operation of the key telephone apparatus including the processing related to the exchange connection is the same as that of the well-known key telephone apparatus, the description thereof is omitted, and the date and time of the calendar unit 15 performed by the calendar correction processing unit 16b are omitted. The following description focuses on the processing related to the information correction setting.

First, in the standby state, the main control unit 16 waits for an incoming call to occur (step b in FIG. 4). When an incoming call occurs, the main control unit 16 determines whether or not date and time information has been detected by the identification information detection circuit 14 (step c).

If the date and time information is not set in the identification information or if the date and time information is not detected in the identification information detection circuit 14 due to circumstances such as the identification information is not superimposed on the ringing signal, the main control is performed. The unit 16 returns to the standby state and waits for another incoming call.

On the other hand, if the identification information in which the date and time information is set is superimposed on the ringing signal and transmitted, and if the date and time information is detected by the identification information detecting circuit 14, the main control unit 16 converts the date and time information into the identification information. In addition to the date and time information received from the detection circuit 14, the date and time information held by the calendar unit 15 is also received (step d). The date and time information received here is stored in a built-in memory (not shown).
Subsequently, the main control unit 16 compares these two pieces of date and time information (step e), and determines whether or not they match (step f).

If the two date and time information match,
Since the date and time information held by the calendar unit 15 is correct,
The main control unit 16 returns to the standby state as it is. On the other hand, if the two pieces of date and time information do not match, the date and time information held by the calendar unit 15 is incorrect, so the main control unit 16 sets the date and time information received from the identification information detection circuit 14 in the calendar unit 15. Then, the date and time information of the calendar unit 15 is corrected and set (step g). Thereafter, the main control unit 16 returns to the standby state.

By the way, when the main power supply is turned on and started from the state where the main power supply is turned off and the operation is stopped, the main control unit 16 first performs a system initial process (step a). In the system initial process, a self-calling process by the self-calling processing means 16a is performed in addition to a general initial process such as a system initial reset process. The self-calling process is a process for making a call to another station line 3 using any one of the station lines 3, that is, calling itself.

After the end of the system initial processing, the main control section 16 shifts to step b, enters a standby state, and waits for an incoming call. At this time, an incoming call is immediately generated by the self-calling process in the system initial process, so that the processes after step c are performed as described above.

Thus, according to the present embodiment, when date and time information is provided from the network, the identification information detection circuit 14 detects this. The date and time information detected by the identification information detection circuit 14 is compared with the date and time information held by the calendar unit 15 to determine whether the date and time information held by the calendar unit 15 is correct. Fifteen
If the date and time information held by is not accurate, the date and time information detected by the identification information detection circuit 14, that is, the date and time information given from the network is set in the calendar unit 15.

Accordingly, the date and time information of the calendar section 15 is automatically corrected, and there is no need for the user to perform setting work for correction. As a result, the burden on the user can be reduced. In addition, since the date and time information provided from the network is accurate information, the date and time information held by the calendar unit 15 is always accurate.

Further, according to the present embodiment, since a call is made to the self in the system initial processing, an incoming call can be generated immediately after startup to obtain date and time information from the network. Accurate date and time information can be quickly set in the unit 15. As a result, the date and time information held by the calendar unit 15 can be made accurate immediately after startup, and the burden on the user can be further reduced by eliminating the need for an initial setting operation by the user.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the identification information detection circuit 1
4 compares the date and time information detected by the identification information detection circuit 14 with the date and time information held by the calendar unit 15, and only when the two do not match, the date and time information detected by the identification information detection circuit 14 is compared with the calendar unit 15.
However, when the identification information detection circuit 14 detects the date and time information, the date and time information may be set in the calendar unit 15 unconditionally.

In the above embodiment, the self-call process is performed in the system initial process, but this process is not always necessary and can be omitted. Further, in the above embodiment, the calendar unit 15 stores the year, month, day, hour, minute,
Although it is assumed that date and time information consisting of information of seconds is managed, it is not necessary to manage all of these information, and it may be possible to manage only some of the above information,
Alternatively, other information such as a day of the week other than the above may be managed.

In the above-described embodiment, the key telephone apparatus connected to the network providing a service called "CLASS" is exemplified. However, the key telephone apparatus has a function of notifying the subscriber of predetermined information relating to date and time. The present invention can be applied to any key telephone device connected to a network. In addition, various modifications can be made without departing from the spirit of the present invention.
