The channels are actually digitally communicated by time division multiplexing, but here, for convenience, they are described as space division type. Therefore, in FIG. 3, description of a circuit for time division multiplexing the D channel and two B channels and a circuit for separating the time division multiplexing is omitted.

FIG. 4 is a diagram showing an example in which the display on the board of the terminal device for the incoming line is refilled and controlled. Since the common control method can be used for the display refill control for the incoming line and the display refill control for the hold line, the following describes the display refill control for the incoming line and the display refill control for the hold line. The explanation of it is omitted.

FIG. 4A shows a state where there is an incoming call on the line AAA accommodated in the current page of the line button "L1" and the lines BBB and CCC accommodated in other pages. The call control processor displays the name of the line AAA on the current page accommodated in the line button "L1" 22-1 on the fluorescent display section 24-1 of the fluorescent display 24 as "aaa" and the corresponding lamp. Blinking 23-1 indicates that the line AAA is receiving an incoming call to the line button "L1". At this time, since the line EEE accommodated in the line button “L2” 22-2 on the current page is not used, it is only necessary to display the line name “eee” on the display unit 24-2 to display the corresponding lamp. We are extinguishing 23-1. Incoming line button "I1" 22-3, "I2" 22-
4 is a line button “L1” of the terminal device which is not displayed on the currently selected page but is displayed on other pages,
When the line accommodated in "L2" or the line BBB and the line CCC, which are lines not accommodated in any page of the line buttons of the own terminal device but set in advance as data, are receiving an incoming call, -3 is the line name "bb
"b" and the line name "ccc" on the incoming call display section 24-4, respectively, and the corresponding lamps 23-3 and 23-
4 is flashing to indicate that there is an incoming line and the line name. In this state, since all incoming lines are displayed on the board of the terminal device, the lamp 23-7 corresponding to the button "refill" 30 is extinguished.

FIG. 4 (B) shows a state corresponding to the incoming call on the line BBB at the time of the incoming call shown in FIG. 4 (A). Incoming line BB
When an incoming call arrives at B or CCC, the incoming line button "I
When 1 ”22-3 is pressed to respond to the line BBB, the display on the board changes to the state shown in FIG. 4B, and the responding line BBB is excluded from the incoming line button“ I1 ”22-3, The display of the corresponding display unit 24-3 is turned off and the corresponding lamp 23-3 is extinguished.Even in this state, since all the incoming lines are displayed on the board of the terminal device, the lamp corresponding to the refill button 30 is displayed. 23-7 is extinguished.

FIG. 4C shows a case where a new incoming call is received, which is not displayed on the currently selected page but is not stored on the line accommodated on another page or on any page of the line buttons of the own terminal device. When the line DDD, which is a line set in advance by data, arrives, the display on the board becomes the state shown in FIG. 4 (C). Since the incoming line button “I2” 22-4, which is the last of the incoming line buttons, is being used to indicate that the line CCC is receiving a call, the lamp 23-7 corresponding to the refill button 30 is displayed in a blinking manner. ,
Notify that there is an incoming call that is not displayed on the board of the terminal device.

FIG. 4D shows a state in which the refill operation is performed. Line DD not displayed on the board of the terminal device
When the operator who has received the incoming call at D recognizes it by blinking the lamp 23-7 and presses down the refill button 30, the display on the board becomes the refilled state shown in FIG. 4 (D). Incoming line button "I2" 22-4 The incoming line button "I2" 2 that has already used the incoming line CCC
While refilling to 2-3, the line name "ccc" is displayed on the corresponding display section 24-3, the corresponding lamp 23-3 is blinked, and the line CCC is being received by the incoming line button "I1". indicate. At the same time, a new incoming line D
The DD is stored in the incoming line button “I2” 22-4, the line name “ddd” is displayed on the corresponding display unit 24-4, and the lamp 23-4 is made to blink, and the incoming line button “I2” is displayed. Indicates that DDD is ringing.
By this processing, since there is no incoming call which is not displayed on the board of the terminal device, the lamp 23-7 corresponding to the refill button 30 is extinguished. Through the above processing, the incoming line is refilled.

In the above description, the method of refilling the incoming line to the forward line is shown, but it is also possible to display the incoming line DDD on the used incoming line button "I1" 22-3. By doing so, when a larger number of incoming line buttons are provided than in the present embodiment and the operator is to select the response order according to the priority of the incoming line of the incoming line in other terminal devices, the incoming line button that is not used is called. If you continue to display it, you can not display the incoming order of the incoming line,
Depending on the incoming line, there is a risk of waiting for a long time and the service of the system will be degraded.Therefore, the operator does not display the incoming call on the used incoming line button, but the operator refills it and displays it in the incoming line display section in the order of incoming calls. By doing so, the order of incoming calls on the incoming line is made clear.

If the refill button 30 is operated in the state where there is an incoming call on the line DDD of FIG. 4C, the incoming call of the line CCC displayed on the incoming call line button "I2" 22-4 is automatically used. Move to line button "I1" 22-3 and receive incoming line DDD line button "I2" 2
Although it is possible to use the automatic refilling method displayed on 2-4, the incoming line button "I1" 22-3 is used for the line BB.
Since the line BBB is abandoned halfway based on the caller's operation in response to the response from another terminal device to B, the line BBB is pushed down by pressing the incoming line button "I1" 22-3. When the incoming line button "I1" becomes unused at the moment of attempting to respond to, there is a possibility that it will be automatically refilled properly and the response will be to the line CCC for which the handler has no intention of responding. It does not use the automatic refilling method.

FIG. 5 is a diagram showing the control of the transaction memory corresponding to the refilling process for the incoming line shown in FIG. 4, and shows the structure and stored contents of the transaction memory provided in the temporary storage device 34. Since the display control for the incoming line and the transaction memory control method for the holding line are also common here, only the transaction memory control for the incoming line will be described, and the description of the transaction memory control for the holding line will be omitted.

As shown in FIG. 5A, the incoming queue head pointer (ICQH) 51 is registered with the transaction memory 52 of the line AAA, indicating that the line is receiving a call. The transaction memory 53 of the line BBB is registered in the linkage 55 of the transaction memory 52 of the line AAA, and the line CC of the transaction memory 53 of the line BBB is registered in the linkage 57 of the transaction memory 53 of the line BBB.
C transaction memory 54 is registered, line CC
In the linkage 59 of the transaction memory 54 of C, "0" indicating that there is no next incoming call is set, and the incoming order is maintained by this linkage. Incoming call type 56 of transaction memory 52 of line AAA
Is set to '0' indicating that the line AAA is displaying the incoming call on the current page of the fluorescent display (VFD), and the incoming call type 58 of the transaction memory 53 of the line BBB is accommodated in the incoming call line button. The order of '1'
Is set, and similarly, the incoming call type 60 of the transaction memory 54 of the line CCC is set to "2".

Here, when responding to the line BBB,
As shown in FIG. 5B, the transaction memory 53 of the line BBB is excluded. Since the line BBB is no longer receiving an incoming call, the incoming queue head pointer (ICQ
H) 51 includes transaction memory 52 of line AAA
Is registered and does not change, however, the line CC is stored in the linkage 55 of the transaction memory 52 of the line AAA.
The C transaction memory 54 is registered. Also,
Incoming call type 5 of transaction memory 52 of line AAA
6 and the incoming call type 60 of the transaction memory 54 of the line CCC do not change because the display on the terminal board does not change.

Next, when the line DDD arrives, the line in FIG.
As shown in (C), the transaction memory 61 of the line DDD is added. As in FIG. 5B, the line AA
Since A is still receiving an incoming call, the transaction memory 52 of the line AAA remains registered in the incoming queue head pointer (ICQH) 51 and does not change.
Since the incoming call on the line DDD is the final incoming call, the line CCC
The transaction memory 61 of the line DDD is registered in the linkage 59 of the transaction memory 54 of
The linkage 62 of the DD transaction memory 61 is set to "0" indicating that there is no next incoming call, and the incoming call type 63 of the transaction memory 61 of the line DDD is set to the transaction memory 54 of the line CCC.
'3', which is next to the incoming call type 60, is set.

Here, when the refill button is pressed,
As shown in FIG. 5D, refilling is executed.
As in FIG. 5B, since the line AAA is still receiving an incoming call, the incoming queue head pointer (ICQ
H) 51 includes transaction memory 52 of line AAA
Remains registered and does not change. Although there is no change in the linkage because there is no change in the incoming order of each incoming line, the incoming call type 60 of the transaction memory 54 of the line CCC
Then, the incoming call type 63 of the transaction memory 61 of the line DDD is refilled and "1" and "2" are set in the incoming order.

Based on the control of these transaction memories, the refill program control will be described below. FIG. 6 is a schematic diagram of a program for controlling the refill lamp corresponding to the refill button. This program is started in a fixed cycle, and in step S1, the incoming queue head pointer is checked to determine whether there is an incoming call. If there is an incoming call, the transaction memories are sequentially extracted in step S2, and it is checked in step S4 whether the incoming call type of the transaction memory is "3" or more. If the incoming call type is less than "3", the process returns to step S2 to extract the next transaction memory and continue the process. If the incoming call type is "3" or more, it means that there is an incoming call that cannot be displayed on the line button or the incoming line button displayed on the current page of the fluorescent display (VFD). By blinking the corresponding lamp, the operator is notified that there is an incoming call that is not displayed on the board of the terminal device.

In this embodiment, since the refilling of the incoming call and the refilling of the hold are controlled by one refill button and the lamp, the lamp corresponding to the refill button is blinked by the incoming call regardless of whether the call is put on hold in step S5. Exit the program.

In step S2, transaction memories are sequentially extracted, and when the incoming transaction memory is exhausted before the condition of step S4 is satisfied, it is determined in step S4 that the transaction extraction is completed,
The process jumps to step S6 to extinguish the lamp corresponding to the refill button, indicating that there are no more incoming calls that are not displayed on the board of the terminal device, and then checks whether or not the call is on hold.

The call hold check is the same as the incoming call. In step S7, the hold queue head pointer is checked to determine whether there is a hold. If there is a hold, the transaction memory is sequentially extracted in step S8, and the transaction memory is extracted in step S10. It is checked whether or not the reservation type of is 3 or more. If the hold type is less than "3", the process returns to step S8 and the next transaction memory is extracted to continue the process. However, if the hold type is "3" or more, the fluorescent display (VF
In order to indicate that the line button or the hold line button displayed on the current page of D) has a hold that cannot be held and displayed, in step S11, the lamp corresponding to the refill button is blinked, and the operator handles it on the board of the terminal device. Notify that there is a hold that is not displayed in and terminate this program.

In step S8, transaction memories are sequentially extracted, and if the pending transaction memories are exhausted before the condition of step S10 is satisfied, it is determined in step S9 that the extraction of the transaction memories is completed, and the process jumps to step S12. In step S12, the lamp corresponding to the refill button is extinguished, indicating that the call hold not displayed on the board of the terminal device is no longer present, and the program ends.

Next, regarding the method of setting the incoming call type and the hold type in the transaction memory when the page is switched by pressing the previous page button, the next page button or the refill button, the outline of the incoming call type and the hold type setting program will be described. This will be described with reference to FIG. In step S21, the incoming queue head pointer is checked to determine whether there is an incoming call. If there is an incoming call, the transaction memory is sequentially extracted in step S22, and the line of the transaction memory is connected to the fluorescent display (VF) in step S24.
It is checked whether the line button displayed on the current page of D) is accommodated, and if accommodated, the incoming type of the transaction memory is set to "0" in step S25. If the line button displayed on the current page is not accommodated, step S26
In step S27, 1 is added to the counter that has been cleared in advance, and the counter value is set in the incoming call type of the transaction memory in step S27.

The above processing is sequentially performed for the incoming transaction memories, and when the processing for all the transaction memories is completed in step S23, the pending type is set next. The setting of the hold type is similar to the setting of the incoming call type, and in step S28, the hold queue head pointer is checked to determine whether or not the call is held. If the call is on hold, the transaction memory is sequentially extracted in step S29, and in step S31, the line of the transaction memory is accommodated in the line button displayed on the current page of the fluorescent display (VFD). Is checked, and if the line button displayed on the current page is accommodated, the hold type of the transaction memory is set to "0" in step S32. If the line button displayed on the current page is not accommodated, 1 is added to the counter that has been cleared in step S33, and the counter value is set in the hold type of the transaction memory in step S34, and this program is executed. finish.

In the above-mentioned invention, the case where an incoming call is received on the line accommodated in the own-seat terminal device and the case where the call of the own-seat terminal device is put on hold is explained. However, there is an incoming call to a terminal device other than the own-seat terminal device. In the case, or when the call is held by another terminal device other than the own terminal device, the refilling can be performed similarly.

[0037]

With the above arrangement, it is possible to visually display that there is an incoming call that is not currently displayed on the incoming terminal device. Furthermore, it is possible to visually display that there is a hold for which the call hold is not currently displayed on the terminal device that held the call. In addition, by displaying the arrival or hold display in this way, the operator knows that there is an incoming call or hold that has not been displayed, and by performing a refill operation, the incoming and holding lines that are not displayed on the terminal device are displayed. The name can be displayed.
