Problems to be Solved by the Invention However, in the conventional electronic exchange described above, the telephone ₁₁
To 1 because each button A~C of _N is allocated fixedly correspond to outside line "1" to "M", the often outside line number than the number of key telephone 1 ₁ to 1 _N, all there is a problem that it is impossible to perform display control of the telephone 1 ₁ to 1 _N for the outside line.

Also, as shown in FIG. 10, as in the case of a dial-in incoming call, a primary incoming call is made by polarity reversal from the central office exchange and a primary response is made, and a preset child number (for example, extension number “5934”, When a call is received by “5935”) and connected to the telephone, even if a plurality of child numbers try to share one dial-in line L in order to control the incoming call of only one preset telephone, There is a problem in that it is not possible to distinguish whether a call has arrived at a child number or not, so that a call cannot be received.

Another problem is that unspecified external line incoming calls cannot be transferred as held calls in groups.

In view of the above-mentioned conventional problems, the present invention can perform display control for an outside line whose number is larger than the number of buttons of a telephone, and can receive a call even if a plurality of child numbers share one dial-in line. The purpose of the present invention is to provide an electronic exchange that can be used.

Means for Solving the Problems In order to achieve the above object, the present invention provides a first storage means for storing a number preset in common for each function button of a plurality of telephones, and an imaginary extension. Second storage means for storing the numbers of the function buttons of the telephone corresponding to the respective numbers in advance, and when a call is received at an imaginary extension, the function buttons of the telephone are referred to by referring to the second storage means. Is searched, and the function button of the corresponding number of each telephone is displayed by receiving a call by referring to the first storage means. When the telephone whose function button displays the reception responds, the responding telephone and the caller are identified. In addition to controlling connection, all incoming calls of function buttons are turned off.

According to the present invention, each function button of the telephone does not correspond to an outside line but corresponds to an imaginary extension according to the above configuration. Therefore, even when the number of outside lines is larger than the number of buttons of the telephone, the incoming call display and the hold display are performed. be able to.

Further, according to the above configuration, when a plurality of child numbers try to share one dial-in line, an incoming call can be made to each telephone by setting the dial-in line to a fictitious extension.

It is a control unit that performs response control, hold control, and the like.

Control section 3a, as shown in detail in Figure 2, the telephone 1 _1,
Extension numbers “1” to “N” assigned to ₁₂ , 1 _N and fictitious extension numbers (actual extension numbers “N + 1” to “N +
m ”) status information (vacant, incoming, on-call, on-hold)
And has a terminal status table T ₁ which the connection partner information is stored, in this example, a hypothetical extension number "1", "2",
“M” (m ≦ 99) has a floating number “1”,
“2” and “99” are assigned.

The control unit 3a also includes, as shown in FIGS. 1 and 2, floating button number is common for each phone 1 _1, 1 ₂ to 1 _N buttons A, B, connection information table T ₃ showing the connection of a C
(Address information) is set in advance.

The control unit 3a further includes, as shown in Figure 1 and Figure 3, and stores the caller information of each floating button number (external number, extension number), and the first button of the telephone 1 ₂ to 1 _N having a floating button management table T ₂ the connection information is set in advance.

In this case, as shown in FIG. 4 (a), an incoming call to an outside line is made to a telephone whose button is set to an outside line, or to an incoming call to a preset telephone (terminal). Although in-line is known, in this embodiment, an extension is set in advance to a fictitious extension (fictitious terminal).

Also, as shown in FIG. 4 (b), a dial tone is sent to the caller in response to the call signal from the central office, and when the caller sends the extension number by the PB signal, the extension number of the caller is transmitted. Although a direct-in dial for connecting to a telephone is known, in this embodiment, the direct-in dial is set in advance for an imaginary extension (an imaginary terminal).

Further, as shown in FIG. 4 (c), there is known a dial-in which receives a primary call by inverting the polarity from the central office exchange, makes a primary response, and receives a primary number (extension number) from the central office exchange set in advance. However, in this embodiment, dial-in is set in advance to a fictitious extension number.

Next, the operation of the above embodiment with reference to FIGS.
In particular, the operation of the control unit 3a will be described.

First, the in FIG. 5, outside line (direct in-line, direct dialing, dial) when coming from or extension to extension, at step 51, refers to the terminal status table T ₁ shown in FIG. 2, in the following step 52 It is determined whether the current state of the terminal having the extension number is idle. If not, the flow branches to step 53, where a busy tone is transmitted to the caller, and the process ends.

On the other hand, if the terminal of the received extension number is empty, the process proceeds from step 52 to step 54, where it is determined whether the terminal of the received extension number is an actual terminal or a fictitious terminal, and if the terminal is an actual terminal. Branch to step 55 to call the terminal.

On the other hand, searches the floating button number from the terminal status table T ₁ proceeds to step 56, if a fictitious terminal, floating button management table shown in FIG. 3
Writing caller information and state information in the area of the floating button number (incoming call) in T _2.

Next, in step 57, the buttons of the telephones 1 ₁ , 1 ₂ to 1 _N are controlled so as to display the incoming call by sequentially referring to the button connection information shown in FIG. 3 and the connection information table T ₃ shown in FIG. , and writes the state information (incoming call) in the terminal status table T ₁ shown in Figure 2.

That is, for example, when the outside line "1" arrives in an imaginary extension "1", as shown in FIGS. 2 and 3, caller information (external to the area number "1" of the floating button management table T ₂ " 1 ") and status information (write in incoming) (step 56), the button information C extension" 1 "by the connection information table T ₃ (telephone 1 ₁₎ of the button information a, the extension" 2 "(telephone 1 ₂₎ , And retrieves the button information B of the extension N (telephone 1 _N ), displays the incoming call, and writes the state information (incoming call) in the area of the fictitious extension “1” of the terminal state table T ₁ (step 57).

Therefore, according to the above embodiment, the telephone ₁ 1, 1 ₂ ~1 _N
Each button A, B, C does not correspond to the outside line, because it corresponds to the imaginary extension, can be number of external arrives also displayed if more than phone ₁ 1, 1 ₂ ~1 _N number of buttons .

Next, the operation of responding to an incoming call to the fictitious extension will be described with reference to FIG.

In the sixth view, or is operated in response button on the phone ₁ 1, 1 ₂ ~1 _N, if it is answered by dialing, step 61
In connection information searching floating button number by the table T ₃ and the button connection information, searches whether the data in the area of the floating management table T ₂ is written.

If no data has been written (if no incoming call is being received), the process branches from step 62 to step 63, and sends a fast busy tone (FBT) to the answering telephone. Continue to 64.

In step 64, controls the network 2 so as to connect the caller with the response telephone written in the floating button management table T ₂ in step 56 of FIG. 5,
In step 65, it erases the calling party information and the status information of the floating button management table T _2, also step
In 66 writes the connection partner and state information in the area of the extension of the response telephone terminal status table T ₁ shown in FIG. 2 (during a call), erase the data of the imaginary extension of the area that arrive.

Then, in step 67, controls to turn off the incoming display by referring to the connection information table T _3.

Therefore, according to the above embodiment, if any of the phone by coming into imaginary extension responds, since its imaginary extension area of the terminal status table T ₁ is is a free, coming back to the imaginary extension (Steps 52 and 54 in FIG. 5).

Next, the hold operation during a call will be described with reference to FIG.

In Figure 7, the telephone 1 ₁ during a call, 1 ₂ to 1 _N buttons A, B, when any one of C is operated, in step 71, the floating button number corresponding to the operated button management table T Referring to the area No. ₂ , it is determined whether data is written.

If data has been written (when another telephone is ringing or on hold), the process proceeds from step 72 to step 73 and ignores the operation. If data has not been written, steps 72 to 74 are executed. proceeds to the write to the floating management table T ₂ the calling party reads from the terminal status table T _1, respectively to the phone and the other party who hold delivering the dial tone holding tone (step 75,
76).

Then, in step 77, by referring to the connection information table T ₃ is controlled such that the buttons of the phone ₁ 1, 1 ₂ ~1 _N is hold display, in the following step 78, an imaginary extension is assigned to the button and discriminates whether or not the that, in the case where assigned proceeds to step 79, writing a "pending" in the area of the state information of the floating management table T ₂ corresponding to the imaginary extension.

Therefore, if you arrive at this pending fictitious extension,
In steps 51 to 53 of FIG. 5, a busy tone is transmitted to the caller.

In this hold display state, the telephone 1 _1, 1 ₂ to 1 or hold the displayed button _N is operated in an off-hook condition, when it is answered by dialing the other party written in step 74 to the floating management table T ₂ If, controls the network 2 to connect the telephone in response, then erases the calling party written in the floating management table T _2, erases the hold display of each phone ₁ 1, 1 ₂ ~1 _N.

Therefore, according to the above embodiment can also be hold display in each case from the outside line number phone ₁ 1, 1 ₂ ~1 _N number of buttons is small, also responds with the hold display.

As shown in FIG. 8 (b), for example if the phone 1 ₁ and the telephone 1 ₂ is transferred to the telephone 1 _N during a call, placed on hold display state by the operation of the floating button on the phone 1 _1, telephone 1 _The transfer is performed by the operation of the floating button displayed with _N on hold, so that the operation is simplified as compared with the conventional transfer operation shown in FIG. 8 (a).

Also, when a plurality of child numbers try to share one dial-in line, the telephone can be received by setting the dial-in line to a fictitious extension.
The floating button number is set as a group number, and when a call is received by a telephone of the group, the call is held by the button of the floating button number, whereby the call can be transferred to the telephone of the group.

According to the present invention, as is apparent from the above embodiment, the invention of claim (1) can perform the incoming call display and the hold display even when the number of outside lines is greater than the number of buttons on the telephone.
If any of the telephones responds by receiving a call at the fictitious extension, the area of the fictitious extension in the terminal status table is empty, so that it is possible to receive a call at the fictitious extension again and to operate the telephone efficiently. It has the effect of being able to.

According to the invention of claim (2), even when the number of outside lines is larger than the number of buttons of the telephone, the incoming call display and the hold display can be performed, and further, a plurality of child numbers try to share one dial-in line. In this case, you can set up a dial-in line for a fictitious extension to receive calls to each telephone,
The floating button number is set as a group number, and when an incoming call is received by a telephone of the group, the call is held by the button of the floating button number, so that it is possible to transfer the call to the telephone of the group.
