Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when called from a calling side, automatically responds to the calling side, and the reason why the call cannot be made is allowed to be sent to the calling side. The present invention relates to a telephone terminal device capable of visible display, and further to a private branch exchange system in which such a telephone terminal device is housed in a private branch exchange as an extension subscriber terminal.

[0002]

2. Description of the Related Art In recent years, telephone service has been remarkably improved by improving a telephone terminal device (hereinafter referred to as a telephone) itself, for example, "Profile of Multi-functional Telephone" (monthly magazine "Computer & Network LAN" (1984 /
In 4)), various services by telephone are introduced.

[0003]

However, even with those telephones, apart from the case where the called telephone is busy, the called telephone is placed in the unresponsive state due to the absence of the subscriber or the like. However, the situation is that the call from the calling side can only be passively dealt with. When a called party in a busy state is called by a third party, a busy tone is generally sent from the exchange to the third party. It is known from the busy tone that the called side is in a call-disabled state, but if the call cannot be answered due to the absence of the called-side subscriber, the called-side telephone must simply be in a continuous ringing state. Under such a condition, the calling side had to make some decision such as once stopping the calling and then calling again.

By the way, in order to solve the above problems, when an incoming call is received while the called subscriber is absent, the incoming call is transferred to a destination specified in advance by the called subscriber. If the so-called (absent) call transfer service is implemented, but the destination is not specified or the service registration is temporarily canceled, the called subscriber The call transfer service is not always provided in the absence, and the caller cannot take appropriate measures despite the fact that the caller needs to make a call with the callee at an early stage. Is.

A first object of the present invention is that when the calling side calls, the calling side automatically responds to the call and the reason why the call cannot be answered is sent to the calling side. The purpose is to provide a telephone terminal device whose reason is easily known. A second object of the present invention is to provide a private branch exchange system in which the reason why the called extension subscriber cannot answer and the later answerable time can be easily known to the calling extension subscriber.

[0006]

A first object of the present invention is to provide a storage unit for storing a reason why a response is impossible and a later response possible time point information inputted from the keypad unit by a key operation as an update possible at any time, and the storage unit. a state that has been stored in the response-friendly time information later with unresponsive reasons part, when the calling signal is detected, an automatic response unit for automatically responding to the call out, automatically responding to the call Then, the response failure reason information sending section for sending the above-mentioned reason why the response is not possible and the later response time point information as a PB signal, and the above-mentioned response after sending the reason for the response failure and the later response time point information as a PB signal. A busy tone sending unit that sends a busy tone with an intermittent pattern corresponding to the reason why
While confirming and displaying the reason why the response is not possible and the later response possible time point information entered from the keypad as visual information, the reason why the response is impossible and the later response possible time point information received as a PB signal are confirmed and displayed as visible information. And a visible display section that includes at least the following.

The above-mentioned second object is achieved by housing the telephone configured as described above in a private branch exchange as an extension subscriber terminal.

[0008]

In each of the called telephones, when there is a call from the calling telephone through the general exchange, the call is automatically answered, and the call cannot be registered in advance in the called telephone. The reason and later response time point information are transmitted as a PB signal, and the busy tone signal corresponding to the reason why the response is impossible is transmitted, while the calling side telephone sets
Based on the decoding result of the reception of the PB signal from the called telephone, the reason why the called telephone terminal cannot respond and the later response time information is visually displayed, and the response from the called telephone terminal By audibly displaying the busy tone signal corresponding to the reason why the call cannot be made, the reason why the called subscriber cannot answer the call can be specifically and easily known.

[0009]

EXAMPLES The present invention will now be described FIG. 1, the Figure 2.
First, referring to FIG. 1, an explanation will be given of a mode in which a telephone according to the present invention is accommodated in a private branch exchange (or a central exchange). As shown in the figure, the telephone (TEL0) 1 has a dial keypad 8 and a display window 7 on its operation surface in addition to the handset 6 and also has a two-wire subscriber line or a four-wire subscriber line. 5. The private branch exchange 3 is accommodated via the subscriber circuit (line circuit) 2 corresponding to the telephone 1, but other telephones in general (not shown, but not necessarily the telephone according to the present invention) are also subscriber circuits. It is housed in the private branch exchange 3 via 4 or the like.

Now, with the telephone 1 according to the present invention, there is a call from the calling telephone via the private branch exchange 3 in a state in which the reason why the telephone cannot answer and the time when the telephone can respond later are registered in advance. In this case, the telephone 1 automatically answers the call, the pre-registered reason why the call cannot be answered and the later-available answer point information as a PB signal, and the busy tone corresponding to the reason why the call cannot be answered. The point that the signal is sent to the calling side telephone is clearly distinguished from the conventional telephones in general. On the calling telephone,
At least the busy tone signal corresponding to the reason for the unresponsiveness is audibly displayed so that the reason for the unresponsiveness on the telephone 1 can be specifically known. At that time, if the calling telephone is configured in the same manner as the telephone 1, coupled with the audible display of the busy tone signal, the reason why the call cannot be answered and the later response is displayed on the display window 7. By displaying the timetable information, the calling side can more surely know the reason why the call cannot be answered and the time when the call can be answered later.

From the telephone 1, in order to prioritize the visible display over the audible display, the reason why the response is not possible and the later response possible point information is transmitted as a PB signal, and then the busy tone corresponding to the reason why the response is not possible. It is desirable that the signal be sent,
Further, as the busy tone signal, it is easy to think that a frequency signal from a specific single frequency signal oscillator, which is prepared in advance for PB signal generation, is transmitted with an intermittent pattern corresponding to the reason why the response is impossible. It is supposed to be. By the way, there is an incoming call request from the calling side telephone to the private branch exchange 3 in the private branch exchange 3 in a state in which the reason why the call cannot be answered in advance and the later-available answer point information is registered as updateable at any time. In such a case, it may be considered that the private branch exchange 3 sends to the calling telephone the busy reason corresponding to the reason why the response is not possible, the later response possible time information, and the reason why the response is not possible. .

Here, the reason for registering the reason why the response is not possible and the later response possible time information in the telephone 1 in advance will be described. That is, in FIG. 2, the display window 7 and the dial keypad 8 in one specific example are shown in detail as a part of the appearance of the telephone 1, but as will be understood from this, a plurality of specific dials are shown. For each key (in this example, dial keys corresponding to the numbers 1 to 6), there is a reason that the key cannot respond to the nearby position (away, during a meeting,
"Going out, etc.) is also displayed in advance.
Therefore, for example, assuming that the subscriber leaves the seat for a short period of time, if the message "leave" is registered as a reason why the response is not possible, first press the "message" registration key twice. When operated, the message registration request is input to the telephone 1, and then the "leave" key, that is, the dial key corresponding to the numeral 1 is pressed. After that, the "message" registration key is pressed once as a registration completion key, so that the reason why the response is "away" is completed. In order to change the reason why the response is currently not registered to another message, the same dial key pressing operation may be performed again. If the "message" registration key is used as a registration completion key and the "message" registration key is not pressed within a certain time (for example, 10 seconds) from the time when it is pressed twice, the contents of the pressing operation before that Will be canceled as invalid. Therefore, when the reason for leaving unanswered is "Away" is registered, if you press the "Message" registration key twice when returning, and leave it as it is, the reason for unresponsiveness that the message was registered until then The "seat" is to be released.

By the way, when not only the reason for not responding but also the later response possible time information is also registered, the calling subscriber is notified of the appropriate later recall time, The service can be improved when recalling. For example, in the case where a message is registered as a reason why the user is "away from the desk" as a reason for not responding, and a case of registering response time information as a scheduled return time is also described, the dial key corresponding to the number 1 is pressed. When operated, a request display “RTN” prompting the user to enter the scheduled return time is displayed on the display window 7 (RTN).
Is an abbreviation of the English word "RETURN". When the display prompts the user to press the dial key "11 # 30", for example, the scheduled return time (in this example, 11:30 on the day) is displayed on the display window 7. 11-30 "is displayed, but after that, the" message "registration key may be pressed once as a registration completion key. After that, on the display window 7, “RTN11
"-30" is displayed. As long as some reason for not responding is registered in the telephone 1,
When a call signal is detected, the call is automatically sent.
It is said that the response is possible. That is, when the telephone 1 is called from the private branch exchange 3 on the basis of an incoming call request to the telephone 1, the telephone 1 automatically answers the call and a communication path with the calling telephone is set. In this state, the telephone 1 first transmits the reason why the response is not possible and the later response possible time point information as a PB signal, and then outputs the busy tone signal corresponding to the reason why the response is not possible. It's good. At that time, the calling telephone is the telephone 1.
In the case of being configured in the same manner as described above, for example, the "leaving away" display as the reason for the unresponsiveness is displayed as a lamp lighting state, and "11-30" as the scheduled return time is displayed on the display window 7. Since it is displayed, it is easy to know that the person is away from the seat at this moment, but the call can be made after 11:30.

Although the reason why the unresponsiveness is "away from the desk" has been described above, the reason is similar for other unresponsiveness reasons. However, when the reason why the response is not possible is "return home", "RTN" indicating return: RETURN is unnecessary, and it is sufficient to simply display the time when the user left the desk to return home. If the reason for not responding is "on vacation", the number following "RTN" is not the time but the date of returning (in this example, November 30
Assuming the day), the time display "11-30" (11
It is necessary to display November 30th at (30 minutes), and "1
If the intermediate display between 1 and 30 is blinked as a mark different from "-", for example, an asterisk symbol corresponding to the "message" registration key, the error disappears.

As can be seen from the above, when the other party's telephone is constructed in the same manner as the telephone 1 , the other party can display various types of display as described above, but the other party's telephone is not necessarily so constructed. Since it is not always the case, the telephone set 1 sends the busy tone signal corresponding to the reason why the response is impossible after the reason why the response is not possible and the later response time point information is transmitted as the PB signal. Has become desirable. Even if the other party's telephone is not a multi-function telephone, the busy tone signal can be audibly displayed on at least the other party's telephone, so that the other party can easily know at least the reason why he / she cannot answer.

Finally, a little supplementary explanation of the connection of a telephone set according to the present invention to a subscriber line will be made so that even a two-line subscriber line can be connected to a four-line subscriber line. It's okay. 2 subscriber lines to and from the telephone exchange
This is because the PB signal can be transmitted / received on the two-line subscriber line even in the line system. It goes without saying that the present invention can also be implemented by a method of using information lines in a so-called multi-function telephone that uses four or more lines. In addition, the letter "RT" indicating the return
N "can be uniquely created and displayed inside the telephone 1 from the numerical information.

[0017]

As described above, according to the first aspect of the present invention, when the calling side is called, the automatic answer is given and the reason for no response is sent to the calling side. , The telephone terminal device which makes it easy for the calling side to know the reason for the unresponsiveness, and in the case of claim 2, the reason for the unresponsiveness at the called extension subscriber and the later time at which the unresponsiveness can be called Private branch exchange systems that can be easily known by extension subscribers are available.
