Abstract

PURPOSE:To make an incoming display and holding display when an incoming call arrives at an aerial extension line even when the number of line wires is larger than the number of buttons of telephone sets by retrieving the number of the functional button of the telephone sets by referring to the 2nd storing means and displaying the incoming call on the functional button of the above-mentioned number of each telephone set. CONSTITUTION:When, for example, an incoming call arrives at an aerial extension line '1' from a line wire '1', the originating subscriber information (state information 4 indicating that an incoming call arrives through line wire '1') is written in the Number '1' area of a floating button management table T2. Then the button information A of extension line '1', button information C of extension line '2', and button information B of extension line 'N' are retrieved in a connection information table T3 and the incoming calls are respectively displayed. Moreover, status information (called state) is written in the area of the aerial extension line '1' in a terminal status table T1. Therefore, the incoming call can be displayed, even when the number of line wires is larger than the number of buttons of telephone sets 11-1N because the buttons A-C of each set are not provided in corresponding to the line wires, but to the aerial extension lines.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to incoming calls on a multi-function telephone connected as a terminal,
It relates to an electronic exchange that controls hold, response, etc.

BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 9, this type of electronic switching equipment has a terminal status table T' for storing status information of stain filling machines 11 to IN based on status information of outside lines "1" to rMJ. ot, and a connection information table TO2 that is fixedly assigned to external lines "1" to rMJ and stores connection information indicating connections between buttons of telephones 11 to IN. For example, when a call is received on external line "1" , the control unit 3 controls the table To
1. Telephone 11 corresponding to outside line "1" with reference to TQ2
The button A1 of the telephone 12, the button C1 of the telephone IN, and the button B of the telephone IN are sequentially searched and these buttons are controlled to display an incoming call.

In this incoming call display state, for example, when button A of the telephone 11 is operated, the network (NW) 2 is controlled to connect the outside line "1" and the telephone 11, and the button A1 of the telephone 11 and the button C1 of the telephone 12 are controlled. Telephone I
Button B of N is controlled to display a call, so that a call can be made between the outside line "1" and the telephone set 110.

When the hold button (not shown) of the telephone 11 is operated in this call state, the network 2 is controlled so that the outside line "1" is put on hold, and the button A1 of the telephone 11, the button C1 of the telephone 12, the telephone IN Button B is controlled so that it is displayed on hold.

For example, when button C of the telephone 12 is operated,
The network 2 is controlled to connect the telephone 12 with the held outside line "1", and the button A1 on the telephone 12, the button C1 on the telephone 12, and the button B on the telephone IN are controlled to display a call again, so that the outside line "1" is connected to the telephone 12. 1" and the telephone set 12.

Note that the above-mentioned incoming call display, call display, and hold display can be displayed with lamps of different colors, or can be displayed with a single color lamp blinking or continuously lighting.

Further, as illustrated in FIG. 8(a), when transferring the extension call state between the telephones 11 and 12 to another telephone IN, when the hold button of the telephone 11 is pressed, the control unit 3 11 and 12, a dial tone and a hold tone are sent respectively, and when a call operation is performed from telephone 11 to telephone IN, telephone IN is called and telephone IN is sent.
When the telephone 11 and the telephone IN are answered, the telephone 11 and the telephone IN are connected to each other, and when the transfer button of the telephone 11 is pressed, the telephone 12 and the telephone IN are connected and the telephone is set to a telephone conversation state.

Problems to be Solved by the Invention However, in the above-mentioned conventional electronic exchange, the telephone 11
~IN buttons A-C are fixedly assigned to outside lines "1" ~rMJ, so telephone 11~IN
If the number of outside lines is greater than the number of buttons, there is a problem that display control of telephones 11 to IN cannot be performed for all outside lines.

In addition, as shown in Fig. 10, when a dial-in call is received, a call is received as a primary response by reversing the polarity from the exchange, and a pre-set sub-number from the exchange (for example, extension number r5934J) is received. , "5935") and connect to that phone, even if multiple child numbers try to share one dial-in line in order to control incoming calls to only one preset phone. , there is a problem that it is not possible to receive a call because it is not possible to distinguish which sub-number the call is received from.O Also, there is a problem that it is not possible to transfer incoming unspecified external calls as a group-based held call. There is.

In view of the above-mentioned conventional problems, the present invention can perform display control for more outside lines than the number of buttons on the telephone.
Another object of the present invention is to provide an electronic exchange that can receive calls even when a plurality of sub-numbers share one dial-in line.

Means for Solving the Problems In order to achieve the above object, the present invention provides a first storage means for storing a common preset number for each function button of a plurality of telephones, and a fictitious extension number. and a second storage means for storing the telephone function button numbers corresponding to each number in advance, and when a call arrives at an imaginary extension, the telephone function button is stored with reference to the second storage means. The first storage means is searched for, and the function button corresponding to the number of each telephone is used to display an incoming call.

According to the present invention, when the function button indicates an incoming call and the telephone answers, the telephone that answered is controlled to be connected to the caller, and all the incoming call indicators on the function button are turned off. 0 The present invention also provides control so that when a function button of a telephone during a call is operated, the function button of the corresponding number of each telephone is displayed on hold by referring to the first storage means. be.

Effects According to the present invention, each function button on the telephone does not correspond to an outside line, but corresponds to a fictitious extension, so that an incoming call and a hold display can be performed even when the number of outside lines is greater than the number of buttons on the telephone. Can be done.

However, according to the above configuration, if multiple child numbers try to share one dial-in line, each telephone can receive calls by setting the dial-in line to the overhead extension.

It is a diagram.

In FIG. 1, 11% 12 to IN are telephones having at least three buttons A, B, C, respectively;
Telephones 11, 12 and IN have extension numbers "1" and 1, respectively.
rNJ is given.

Note that buttons A, B, and C of the telephone 11 are assigned floating button numbers "1", "99", and "2", respectively, and buttons A, B, and C of the telephone 12 are assigned floating button numbers "1", "99", and "2", respectively. 99'', ``2'', and ``1'' are assigned to the telephone IN buttons A1B and C, respectively.
Floating button numbers "2", "1", and "99" are assigned.

2 is a network (NW) for selectively connecting an outside line and telephones 11N 12 to IN, and selectively connecting telephones 1112 to IN; 3a is for incoming call control and response as described later; This is a control unit that performs control, hold control, etc.

The control unit 3a, as shown in detail in FIG.
．． 12. Extension number assigned to IN “11~” Every NJ,
and fictitious extension number (actual extension number rN+1” ~ rN
+mJ) status information (vacant, incoming call, busy, on hold)
and a terminal status table T1 in which connection partner information is stored, and in this embodiment, fictitious extension numbers "1" and "2" are stored.
, rmj (m≦99) has a floating number “1”,
"2" and "99" are assigned.

As shown in FIGS. 1 and 2, the control unit 3a also controls each of the telephones 11, 12 to 12 having a common floating button number.
A connection information table T3 (address information) indicating the connection between IN button A and BSC is set in advance.

The control unit 3a further includes 7 as shown in FIGS.
It stores caller information (external line number, extension number) for each 0-ting button number, and also has a floating button management table T2 in which initial button connection information of telephones 11 to IN is set in advance.

Here, as shown in Fig. 4(a), incoming external calls include receiving an external line to a telephone whose button has been set to the external line, and direct calls receiving an extension to a preset telephone (terminal). In-line is known, but in this embodiment, it is set in advance so that an extension call is received on a fictitious extension (fictitious terminal).

Further, as shown in Fig. 4(b), in response to a call signal from the central office exchange, a dial tone is sent to the caller, and when the caller sends a PB double signal extension number, the extension number is Direct in-dials that are connected to telephones are known, but in this embodiment, direct in-dials are set in advance to overhead extensions (overhead terminals).

Furthermore, as shown in FIG. 4(c), a dial-in method is known in which a call is initially received by reversing the polarity from the central office exchange, the primary response is received, and the call is received using a preset sub-number (extension number) from the central office exchange. However, in this embodiment, dial-in is set in advance to a fictitious extension number.

Next, the operation of the above embodiment, particularly the operation of the control section 3a, will be explained with reference to FIGS. 5 to 7.

First, in Figure 5, the outside line (direct inline,
When a call is received from an extension (or from an extension), in step 51, the terminal status table T1 shown in FIG. Determine whether or not. If it is not available, the process branches to step 53, a busy tone is sent to the caller, and the process ends.

On the other hand, if the terminal whose extension number received the call is idle,
The process proceeds from step 52 to step 54, where it is determined whether the terminal with the incoming extension number is an actual terminal or a fictitious terminal. If it is an actual terminal, the process branches to step 55, and that terminal is called.

On the other hand, if it is a fictitious terminal, the process proceeds to step 56, where the floating button number is searched from the terminal status table T1, and the caller information and status are stored in the area of the floating button number in the floating button management table T2 shown in FIG. Write information (incoming call).

Next, in step 57, the button connection information shown in FIG. 3 and the connection information table T3 shown in FIG. Terminal status table T shown in Figure 2
Write status information (incoming call) to 1.

That is, for example, when a call arrives from an outside line rzJ to an overhead extension "1", as shown in FIGS. 2 and 3, the caller information (external line "1" ”) and status information (incoming call) (step 56), button information A1 extension “2” of extension “1” (telephone 11) is written according to the connection information table T3.
(telephone 1ω button information C1 aN (telephone IN)
The button information B is searched to display an incoming call, and the status information (incoming call) is written in the area of the virtual extension "1" in the terminal status table TI (step 57).

Therefore, according to the above embodiment, the telephones 11.12-
The IN buttons A, B, and C do not correspond to outside lines, but correspond to overhead extensions, so the number of outside lines is 11.12 to IN.
Incoming calls can be displayed even if there are more buttons than the number of buttons.

Next, the operation of responding to an incoming call to the above-mentioned overhead extension will be explained with reference to FIG. 6. In FIG. In step 61, the 70-ting button number is searched based on the connection information table T3 and the button connection information, and it is searched whether data has been written in that area of the floating management table T2.

If no data has been written (if no call is being received)
In step 62, the process branches to step 63, and a first busy tone (FBT) is sent to the answering telephone.
If data has been written, the process advances from step 62 to step 64.

In step 64, the network 2 is controlled to connect the answering telephone with the caller written in the floating button management table T2 in step 56 of FIG. 5, and in the subsequent step 65, the caller information in the floating button management table T2 is and erase the state information, and also
In step 66, the terminal status table Tl shown in FIG.
writes the connected party and status information (calling in progress) in the extension number area of the answering telephone, and erases the data in the area of the overhead extension that received the call.

Next, in step 67, the connection information Chiful T3
control to turn off the incoming call display.

Therefore, according to the above embodiment, when a call arrives at an overhead extension and one of the telephones answers, the area for that overhead extension in the terminal status table T1 is empty, so the call is not received again at this overhead extension. (steps 52.54 in FIG. 5).

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

In FIG. 7, when any of the buttons A, B, and C of the telephones 11, 12 to IN is operated during a call, step 7
1, the area of the floating button number management table T2 corresponding to the operated button is referred to to determine whether data has been written.

If data is being written (another phone is receiving a call,
If the call is on hold), the process proceeds from step 72 to step 73 and ignores the operation. If no data has been written, the process proceeds from step 72 to step 74, reads the other party from the terminal status table TI, and performs floating management. This is written in table T2, and a dial tone and a hold tone are sent to the telephone set on hold and the other party, respectively (steps 75 and 76).

Next, in step 77, the connection information Chiful T3
With reference to , the button on each telephone 11, 12 to IN is controlled to be displayed on hold, and in the following step 78,
Determine whether or not a virtual extension is assigned to the button, and if so, proceed to step 79 and write "on hold" in the status information area of the floating management table T2 corresponding to the virtual extension. .

Therefore, when a call arrives at this on-hold virtual extension, a busy tone is sent to the caller in steps 51 to 53 of FIG.

In this hold display state, when the button on the telephone set 11.12-IN that is displayed on hold is operated in the off-hook state or a response is made by dialing, the answering party and the other party written in the floating management table T2 in step 74 are Network 2 like connecting a phone
, and then deletes the other party written in the floating management table T2, and controls each telephone 11N 12.
~Delete the IN hold display.

Therefore, according to the above embodiment, even when the number of buttons on each telephone 11, 12 to IN is smaller than the number of outside lines, a hold display can be displayed, and a response can be made using this hold display.

As shown in FIG. 8(b), for example, when the telephone 11 and the telephone 12 are in the middle of a call and the call is transferred to the telephone IN, the operation of the floating button on the telephone 11 puts the telephone on hold and the telephone IN is put on hold. Transferred by operating the displayed floating button, therefore, as shown in FIG. 8(a)
The operation is simpler than the conventional transfer operation shown in .

Additionally, if multiple sub-numbers try to share one dial-in line, each phone can receive calls by setting the dial-in line to an overhead extension.Furthermore, by setting the floating button number as a group number, When a call arrives at a group phone, the call can be transferred to the group phone by placing the call on hold using the button corresponding to the floating button number.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention includes a first storage means for storing a common preset number for each function button of a plurality of telephones, and a first storage means for storing a common preset number for each function button of a plurality of telephones; and a second storage means for storing function button numbers corresponding to each other in advance, so that when a call arrives at a fictitious extension,
The second storage means is referred to to search for the number of the function button of the telephone, the first storage means is referred to and the function button of each telephone is set to display an incoming call, and the function button is set to display an incoming call. When the telephone that answered the call answers, the telephone that answered the call is controlled to be connected to the caller, and all incoming call displays on the function buttons are turned off, and further,
If the function button on the phone is operated during a call, the first
Since the function button of each telephone set is controlled so that the function button of the corresponding number is displayed on hold by referring to the storage means of In addition, if multiple child numbers try to share one dial-in line, each telephone can receive calls by setting the dial-in line to an overhead extension.
