Abstract

PURPOSE:To obtain the telephone set by which accurate calender information and time information are provided at all times and in which the load of the operator is relieved by forcibly updating information managed by a management means based on received information. CONSTITUTION:When date time information is given from a network, it is detected by an identification information detection circuit 14. The date and time information detected by the identification information detection circuit 14 is compared with date and time information stored by a calendar section 15 to discriminate the acceptance of the date and time information stored by the calendar section 15 and when both the date and time information sets are anticaincident and the date and time information stored in the calendar section 15 is inaccurate, the date time information detected by the identification information detection circuit 14, that is, the date time information given from the network is set to the calendar section 15. Since a call is made to itself in the system initializing processing, a received call is generated immediately after the system rising to obtain the date time information from the network.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In many key telephone devices, date and time are displayed on a display unit of a terminal, for example. In such a key telephone device, the main device has a calendar unit for managing the date and time, and the calendar unit updates and manages the date and time. The update management of the date and time in this calendar unit is performed by counting the clocks generated by a clock source including a built-in crystal oscillator.

Therefore, since the date and time are not managed when the power is turned off, the user must operate each terminal or a specific terminal to key in the current date and time when the system is started up. Further, even during the operation of the system, the error in the date and the time increases due to the accumulated error in the clock, and therefore the user has to periodically input the correct date and time.

Generally, these date and time input operations are
The procedure is as follows. That is, for example, to set "13:59:00 on Aug. 20, 1993", first grab the extension key (INT) and then dial the special number (eg # 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. Furthermore, a special number indicating the time setting (for example, # 65
Press the dial key to input 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 the determination is pressed.

As described above, the work of setting the date and time is troublesome and burdens the user. In addition, if there is an input error or if no correction is made, the date and time will remain wrong 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, the time information, etc. designated by the user. Since information is updated and managed, there is a problem that incorrect information is managed unless the user frequently performs complicated setting work for correction.

The present invention has been made in consideration of such circumstances, and the purpose thereof is to be able to automatically correct calendar information and time information, thereby always providing accurate calendar information and time information. An object of the present invention is to provide a key telephone device capable of providing time information and reducing the burden on the operator.

[0008]

In order to achieve the above object, a first invention is to receive predetermined information such as identification information given from a network via an outside line such as a station line when receiving a call, for example. Receiving means such as an identification information detection circuit,
For example, a forced update means such as a calendar correction processing means is provided, and by this forced update means, predetermined information such as date and time information managed by the management means based on the predetermined information received by the receiving means is displayed. I forced it to update.

A second aspect of the present invention is the compulsory update means of the first aspect of the invention, which compares the predetermined information received by the receiving means with the information managed by the managing means, and when they do not match. The information managed by the management means is forcibly updated.

Further, a third invention is based on the first and second inventions.
In addition to the invention described above, a call processing means such as a self-call processing means is provided, and at the time of system initial processing by this call processing means, one of the plurality of outside lines is used by using one of the plurality of outside lines. I made a call to another outside line.

[0011]

By taking such means, according to the first and second inventions, when predetermined information is given from the network via the outside line at the time of incoming call, this information is received by the receiving means. At the same time, the information managed by the management means is forcibly updated based on the received information.

Therefore, the information managed by the management means is automatically updated based on the information provided from the outside.
According to the third aspect of the invention, since a call is made to itself during the system initial processing, an incoming call is generated and predetermined information is obtained from the network, and the information managed by the management means is forced based on this information. Will be updated. Therefore, after the system initial processing, the information managed by the management means is automatically and promptly updated based on the information provided from the outside.

The main control section 16 controls each section in order to realize the exchange operation. The main control unit 16 includes, for example, a microcomputer as a main control circuit, and has a self-call processing unit 16a and a calendar correction processing unit 16b in addition to a well-known general control unit in a key telephone device. is doing. Of these, the self-call origination processing means 16
“a” is a process for making a call to any one of the outside lines 3 at the system initial after the power is turned on. Further, the calendar correction processing means 16b performs a process of correcting and setting 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, and a C
It has a PU 23, an interface unit 24, a serial / parallel conversion unit 25, and a tone detection unit 26.

By the way, this embodiment is connected to a network for providing a service called "CLASS" provided in the United States. This "CLASS"
In the above, the network transmits the predetermined identification information to the subscriber by superimposing it on the ringing signal. The ringing signal is a signal of a predetermined frequency as shown in FIG.
It is a signal that repeats ON for 1 second with FF in between.
The modem signal in which the identification information is modulated is superimposed on the FF for 3 seconds. The identification information includes date and time information, a caller identification number, etc., and has the format shown in FIG. 3B, for example.

A station line 3 is connected to the modem signal detecting section 21, and a modem signal is detected from signals coming through the station line 3 and given to a data detecting section 22 and a serial / parallel converting section 23. .

The data detector 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.

Next, the operation of the key telephone apparatus configured as described above will be described according to the control procedure of the main control section 16. Note that the general operation of the button telephone device including the processing relating to the exchange connection is the same as that of a known button telephone device, and therefore its explanation is omitted and the date and time of the calendar unit 15 performed by the calendar correction processing means 16b. The description will focus on the process related to the information correction setting.

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

If the date and time information is not detected in the identification information detection circuit 14 due to the circumstances such as the date and time information is not set in the identification information or 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 transmitted while being superimposed on the ringing signal and the date and time information is detected by the identification information detection circuit 14, the main control unit 16 will identify this date and time information. In addition to receiving 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 they match (step f).

If the two pieces of date / time information match,
Since the date and time information stored in 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 / time information do not match, the date / time information held by the calendar unit 15 is incorrect, so the main control unit 16 sets the date / time information received from the identification information detection circuit 14 in the calendar unit 15. Thus, the date and time information of the calendar unit 15 is corrected and set (step g). After that, the main control unit 16 returns to the standby state.

When the main power source is turned off and the operation is stopped and the main power source is turned on and activated, the main control section 16 first performs a system initial process (step a). In this system initial processing, in addition to general initial processing such as system initial reset processing, self-calling processing by the self-calling processing means 16a is performed. The self-calling process is a process of making a call to another station line 3 by using one of the station lines 3, that is, a process of calling itself.

After the system initial processing is completed, the main control section 16 proceeds to step b to enter the 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, and therefore the processes after step c are performed as described above.

Thus, according to this embodiment, when the date and time information is given from the network, the identification information detection circuit 14 detects this. Then, the date / time information detected by the identification information detection circuit 14 is compared with the date / time information held by the calendar unit 15 to determine whether the date / time information held by the calendar unit 15 is correct. 15
If the date and time information held by is incorrect, 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.

Therefore, the date and time information of the calendar unit 15 is automatically corrected, and the user does not need to perform setting work for correction. This can reduce the burden on the user. Moreover, since the date and time information given from the network is accurate, the date and time information held by the calendar unit 15 is always accurate.

Further, according to the present embodiment, since the call is made to itself in the system initial processing, it is possible to immediately make an incoming call after the start-up and obtain the 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 user's burden can be further reduced by eliminating the need for the user's initial setting work.

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 calendar unit 15 with the date and time information held by the calendar unit 15. Only when they do not match, the date and time information detected by the identification information detection circuit 14 is determined by the calendar unit 15.
However, when the identification information detection circuit 14 detects the date / time information, the date / time information may be unconditionally set in the calendar unit 15.

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

In the above embodiment, the key telephone device connected to the network for providing the service called "CLASS" is illustrated, but it has a function of notifying the subscriber side of predetermined information regarding the date and time. The present invention can be applied to any key telephone device connected to a network, even if connected to any network. In addition, various modifications can be made without departing from the scope of the present invention.
