Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to functional group assignment (hereinafter also referred to as tenant division) in a button telephone device that has a built-in microprocessor in its main device and controls telephones, etc. using a storage program method. It is related to the control method.

(Prior art and its problems) In recent years, "key telephone devices" have been equipped with one main device and multiple button telephones, and the main device accommodates multiple office lines (including PBX extensions), and each The button telephones are connected to their main device, and the main device includes a switch circuit network and a program means for controlling it, and the main device includes a switch circuit network and a program means for controlling it. It is configured so that the connection can be made.

In conventional key telephone devices of this kind, when dividing tenants, the central office lines and key telephones accommodated are grouped in a certain relationship, and various functions of the key telephone device, such as hold transfer, etc., are grouped. , call, incoming, outgoing, and telephone calls are completely dedicated (closed) within the group, or have several commonly used office lines, and only the use of those office lines is non-dedicated or open (free). Just as it was said that the level of exclusive use can be relaxed depending on the situation, the usage has become such that, from the perspective of a certain function, it is either completely closed or completely free. In cases where the only options are completely closed or completely free usage, when it is completely dedicated, the hardware is the same system, but the software is separate equipment, and the central office lines between individual groups are Transferring calls on hold causes inconveniences such as having to call back using another station line or having the other party call back. In addition, even if there is a group that does not want to use the line if it is completely free, if a station line that two or more groups want to use arises, it becomes free for all groups, causing problems such as not being able to handle it.

(Objectives and Features of the Invention) The present invention provides a tenant control system for key telephone devices that makes the most of the feature that the hardware is the same and can be used more conveniently.

The basic principle of the present invention is to enable flexible tenant division by allocating telephone line groups and telephone groups to each functional unit (for example, calling from a central office line, receiving a telephone call from a central office line, receiving a call from a central office line, and transferring calls on hold, etc.). be.

(Structure and operation of the invention) The present invention will be explained in detail below using the drawings.

FIG. 1 is a system configuration diagram of an embodiment of the present invention. In the figure, 1 indicates a line key 1-1a and a line status display 1 that indicates the usage status of the office line, extension line, etc.
-1b, a variable display 1-2 composed of a liquid crystal etc. and displaying the other party's telephone setting number, call charges, etc.;
Control circuit 1-3 including transmission control with SUB, handset 1-4, hold key 1-5, speaker 1-6
It is a key telephone KT1 equipped with the following functions. KT2,
KT3,..., KT1x are also button telephones and have the same configuration as telephone 1 (KT1).
ME is the main device, SW is the communication path network (switch group), and 2 (SUB) is the key telephone KT1 to KT.
(x) and the control circuit CPU3. 3 (CPU) is a microcomputer that exchanges data between the read-only memory 4 (ROM) and the temporary memory 5 (RAM), and also controls the control center of this system, and performs all of the control calculations of the present invention. is being done here. 6 (COT) is an interface circuit with the office lines 7-1 and 7-2. 7-1 and 7-2 indicate central office line groups (COGs) that are subject to the division of each tenant group, and 8-1 and 8-2 similarly indicate telephone group groups (KTG) that are subject to division of each tenant group. ) is shown.

Here, among the functions of the key telephone device, the central office line incoming call answering operation will be explained. Control circuit (microcomputer) CPU of button telephone main device ME
The button telephone KT-1...
The control circuits (processors) 1-3 of the KT-1x each operate according to a program stored in advance in a read-only memory (not shown).

Control circuit CPU is interface circuit COT
By sequentially referring to an incoming call detection circuit (not shown), it is constantly monitored which office line CO-1...CO-1y receives an incoming call.

In addition, in the general incoming call mode, when a call is received from the central office line, which key telephone among the key telephones KT-1 to KT-1x is to play the central telephone ringtone is specified in advance in the RAM. There is.

While operating the general incoming call mode, the central office line CO-1,...
When there is an incoming call to any CO-1y, an incoming call detection circuit in the interface circuit detects incoming call information, and this is sent to the control circuit CPU.

The control circuit CPU reads out the button telephone specified for ringing from the random access memory RAM, and
The communication path network SW is controlled, and a sound source circuit (not shown) is connected to a key telephone, for example, KT-1.

As a result, on the button telephone KT-1 side, the central office line ringing tone is emitted from the speaker 1-6. At the same time, a line status indicator 1-1b consisting of a light emitting diode or the like corresponding to the receiving station line lights up or blinks.

On the button telephone KT-1 side, line key 1-1a
When you operate the keyboard to select the central office line for incoming calls and pick up the handset 1-4 to answer, the control circuit 1-3 of the key telephone KT-1 detects this and transmits the response signal to the key telephone main unit. Sends to control circuit CPU on ME side.

In response to this, the control circuit CPU disconnects the sound source circuit from the communication path network SW, and
Form a loop in the interface circuit COT,
Then, for example, the office line CO-1 is connected to a button telephone set to ring, for example, via the interface circuit COT, the communication path network SW, and the repeater 2.
Connect to KT-1.

In this way, the central office line CO-1 and the key telephone
A communication path between KT-1 is established.

Next, details of the present invention will be explained using FIGS. 2, 3, and 4. All of the following explanations are performed by calculations within the microcomputer 3. Second
In Figures 1 and 3, COG1, ... COG5, ... indicate station line groups that are subject to division of each tenant group in group units corresponding to station lines 7-1 and 7-2 in Figure 1, and KTG1 ,...KTG4,...
shows telephone (KT) groups to be divided into tenant groups in units of groups corresponding to telephone groups 8-1 and 8-2 in FIG.

FIG. 2 shows a conventional tenant division method, and FIG. 3 shows a tenant division method according to the present invention.

In Figure 2, tenant group 1 is COG
1 and KTG1, KTG2, KTG3, KTG4
COG1 represents a completely free tenant division in which all KT groups can make calls, receive calls, and transfer calls on hold. For tenant groups 2, 3, and 4, COG2 is KTG1, COG3 is KTG2, and COG.
4 shows a completely closed tenant division form in which outgoing calls, incoming calls, and hold transfers can only be made with KTG3, and use in any other combination is not possible.

As mentioned above, in the conventional tenant division method, all three functions of outgoing calls, incoming calls, and hold transfers are linked and divided into tenants, so it is possible to only allow hold transfers between each KTG, or to allow only incoming calls and hold transfers. It is not possible to satisfy such demands. The tenant division method proposed by the present invention in order to meet such demands will be explained using the tenant division method shown in FIG. 3 as an example. As you can see from the diagram, the concept of how to divide tenants is fundamentally different. In the conventional system, there was a tenant group, and tenants were divided according to which station line group and KT group were included in the tenant group, and functions were uniformly restricted for groups that were not included. In addition, functions such as outgoing calls, incoming calls, hold transfers, etc. were enabled in conjunction with the included calls. The tenant division method of the present invention is centered on functional units, and tenant division is done by assigning the function to which station line group and KT group can be used (or restricted). The method is to do this. Of course, the conventional method of dividing tenants is also possible with this method, but it is possible to do things like allowing hold transfer only to a station line group in a certain KT group.
Requests such as allowing only incoming calls and hold transfers can be easily handled. For example, COG5 in the double circle of functional unit C (hold transfer) in Figure 3 and
The assignment of the KTG1 combination indicates that pending transfer is possible only for this group.

Next, we will explain in more detail how the above calculations are carried out in the microcomputer, focusing mainly on the hold transfer function (both outgoing and incoming calls are basically the same) using Figures 4 to 7. explain.

First of all, Fig. 4 shows COG1, COG2,
It is a configuration diagram of a system that takes into account tenant division and shows only the relationship between COG5, KTG1, and KTG4. In the figure, the part surrounded by the dashed line is the third
The relationship within the circle other than the double frame in functional unit C (hold transfer) in the diagram is the same, and KTs within the group are capable of calling, receiving, and holding transfer functions for the station line within the group. shows. In other words, in functional unit A (calling), functional unit B (incoming call), and functional unit C (hold transfer) in Figure 3, (●
It can be seen that it is possible because it is included in these functions without any restrictions. The area surrounded by broken lines is the same as the relationship within the double circle in Figure 3, and KTs within the group can only perform the hold transfer function for the station lines within the group, but cannot make or receive calls. Show that something is true. That is, COG5 and KTG1
is set only in the functional unit (hold transfer) in Figure 3, and is not included in anything else, so
This combination is set to enable only the hold transfer function. The hold transfer function is a function that allows a station line that is on hold to be placed in a call state by responding to a hold call on another station line within the same group. For example, COG5 (CO51~
All CO5y are the same) and KTG4 (KT41~
(all KT4x are the same), when the KT4x presses the hold key (1-5 in Figure 4) while the KT4x is busy making a call or answering a call using the CO5y's central line, the CO5y will Transition to pending state. At that time, the line status display 1-1 of the corresponding line key displays a hold display (no display when empty, and an incoming call display when an incoming call is in progress). The KT in the group, for example KT41, uses the pending station line.
When you perform a line capture operation on the line key (displayed on hold) on your own KT41, the microcomputer (CPU) 3 that receives the input selects the corresponding line (CO5y here) and the corresponding KT (here CO5y) shown in Figure 5. ,
KT41) is judged based on the hold transfer restriction information, and if the hold response is possible (anything other than the bold line in Figure 5 indicates that it is restricted), the call is determined to be on the central line due to hold response (transfer). , displays a busy display to indicate that the call is in progress.

Next, although the above explanation was for a group in which both outgoing calls, incoming calls, and hold transfers are possible (dotted chain line in Figure 4), an explanation will be given using as an example a group in which only hold transfers are possible (in Figure 3). double circle, dashed line in Figure 4). For example, similar to the above explanation, if KT4x is a central line
If the hold key 1-5 is pressed during a telephone conversation with the CO5y, the CO5y will be put on hold. At that time, all of KTG4
Not only the line keys corresponding to CO5y of KT, KT41, 42, 43, etc. are displayed as being on hold, but also the line keys of all KTs of KTG1 are displayed as being on hold. Therefore, KT in KTG1, for example,
When the KT 11 performs a line capture operation on the line key (displayed on hold), the microcomputer (CPU) 3 that receives the input
Corresponding lines in the diagram (here CO5y, CO51, CO
52) and the hold transfer restriction information of the corresponding KT (in this case, KT11), but according to Figure 5, there is no hold transfer restriction (bold line frame), so a hold response is possible. , hold response (transfer)
This transitions to a central office line call. However, this KTG1,
COG5, CO51 for KT11~KT1x
As shown in FIG. 5, CO5y cannot make or receive calls because the corresponding information is unmarked (not set).

Next, the information constituting the tenant classification shown in FIG. 5 will be further explained. The information indicates that three information sources are provided in a matrix: line-based (or line group-based), function restriction type-based, and KT-based (KT group-based may be used).
This information is held as subscriber data and is used by the microcomputer (CPU) 3 when determining functional limitations associated with each KT operation. In FIG. 5, unmarked telephones (telephones outside the bold line frame) are shown to be subject to functional restrictions, and KTs within the bold line frame indicate that the function of that line is permitted. Fifth
The illustrated example shows the relationship in FIG. Therefore,
COG1, CO11～CO1y, COG2, CO21～
KTG1, KT11~KT1x for CO2y
indicates that outgoing calls, incoming calls, and hold transfers are all possible, and all other things are restricted. or,
For COG5, CO51~CO5y, KTG4,
KT41 to KT4x are allowed to make calls, receive calls, and hold transfers, and only hold transfers are allowed to KTG1 and KT11 to KT1x, and other relationships (KT
and functions) are all restricted.

Next, how the information constituting the tenn division shown in FIG. 5 is set will be explained using FIG. 6. In FIG. 6, m1 to m5 indicate a series of setting operations KT, S0 to S2 indicate a series of operation transition states accompanying settings, and P1 indicates a microcomputer (CPU) 3 corresponding to the series of setting operations. The main processing above is shown. This setting is assumed to be possible only from a specific KT. When a hookup m1 is performed when the specific KT is empty at S0, the state becomes an extension DT (dial tone) connection S1. Then press the tenant information setting key.
If you do 2, the state will be S2 where tenant information is being set. This operation may be a combined operation of the function key plus α. In this state, specify and input the line (station line), function restriction type (information), and KTG (KT itself may be used). Microcomputer (CPU) 3
receives these inputs and sets and registers the specified line, function restriction type, and information constituting the tenant classification specified by KTG as permission information for that function. KTGs (KTs may also be used) that are not specified are treated as restricted.
In addition, after a series of processes, the state is returned to tenant information setting (S2) to enable continuous input.

Next, using the operation flowchart in Figure 7,
The operations within the microcomputer will be explained in more detail. The above explanation of FIGS. 4 to 6 has focused on the hold transfer function, but in FIG. 7, outgoing and incoming calls will also be explained in the same line.
This is because the difference between hold transfer, outgoing call, and incoming call is the state of the office line (line) during the office line (line) capture operation,
That is, the decision method (algorithm) and the like are exactly the same, except for the area where the function restriction information is viewed in response to the line status display, such as a hold display when the call is on hold, no display when the call is empty, and an incoming call display when the call is received. In Fig. 7, m1 indicates a station line capture operation such as pressing the line key of a corresponding line from a KT in a certain KTG, and P1 to P8 indicate m1's line capture operation.
The processing of the microcomputer corresponding to the input operation of KT is shown, and S1 and S2 show the state of KT corresponding to each processing. Next, we will explain the flowchart step by step. When a KT in a certain KTG inputs a station line (line) capture operation, the signal is sent to the microcomputer (CPU) 2 via the repeater (SUB) 2. The microcomputer (CPU) 2 that received the information determines the line (office line), function restriction type (here, outgoing, incoming, hold transfer), as shown in the example in Figure 5.
P1, P2, P4, based on the function restriction information preset for KTG (or KT itself),
Judgments P5 and P7 are made. That is, P1, P4
Depending on the state of the central office line, such as empty, incoming, or on hold, the operation KT corresponding to each state is determined.
P2, P5, and P7 to determine whether or not the operation (which may be determined as a KT group) was possible based on the above functional restriction information. As a result, if the call is possible, processing P3 for making a call to the central office line is carried out, processing P6 for responding to the central office line is carried out if the call can be answered, and processing P8 for answering the holding response (transfer) is carried out if it is possible to answer the call. ,
A transition is made to state S2 in which a call is in progress with the central office line. If not possible, the operation input of m1 is ignored and the state of S1 remains.

(Effects of the Invention) As explained above in Figures 2 to 7, in the conventional system, the three functions of calling, receiving, and hold transfer are linked, so it is possible to set up individual functions such as allowing only hold transfer between each KTG. However, in the present invention, it is possible to perform flexible tenant division based on support for each individual function in response to such group support.

The above explanation explains how to make and receive calls when using a central office line.
Although the explanation has been limited to hold transfer as an example, the above concept can also include other line types such as leased lines and extension lines in the central office line, and tenant division by function can also be applied to outgoing, incoming, and on hold calls. It can be applied to tenant division by all functional units, not limited to transfer.
