Abstract

PURPOSE:To reduce cost by selecting a small representative group in a large representative group with the selection of the representation of a terminal equipment in the small representative group and setting the same terminal equipment to be common in plural representative groups. CONSTITUTION:When a slave extension 201 is used for an incoming call for the slave extension 201 in the small representative group 1 from a central office 14, a central processing unit 12 extracts the small representative group 1 from a small representatibe group list stored in a storage device 13. Since the type of trunk line representative selection is a switch back system, the small representative group 1 makes a round in the representative group until the idle extension of the small representative group 1 is detected. If all the slave extensions are busy, a large representative group list is referred to based on a master extension 200 in the small representative group 1, and the master extension 300 of a next small representative group 2 is extracted. Thus, the extension of the unnecessary terminal equipment is not required and cost can be reduced.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is an automatic switching device consisting of a plurality of terminal devices, in which when a receptionist is unavailable, a terminal is installed so that any other receptionist can respond. The present invention relates to a representative group selection device in an automatic switching device that allows equipment to be selected.

(Prior Art) In an automatic telephone switching system, in a business where telephone reception is the main task, a plurality of receptionists are constituted as a representative group in case one of the receptionists is busy or unable to answer the call due to being away from the desk, etc. The method used is to have someone from the representative group respond on your behalf.

However, if there are multiple departments with multiple receptionists, if all the receptionists in one department are unable to respond, the only option is to ask receptionists in other departments to respond.

In addition, in a system where a secretary receives a call from an executive when the executive is unable to answer due to a conversation, etc., it is not possible to have a common group of secretaries representing multiple executives. It was necessary to create a representative group of secretaries for each person.

This is applicable not only to telephone exchanges, but also to automatic exchange systems that provide facsimile terminal agency services by connecting facsimile terminals (facsimile machines, etc.) and facsimile mail devices that have the ability to store and deliver image information (facsimile information). The same can be said about

For example, in a representative group consisting of a plurality of facsimile terminals, when all the facsimile terminals are unable to respond, it is not possible to divert incoming calls to the representative group consisting of the accommodation lines of facsimile mail devices.

The same can be said of automatic telephone switching systems that are connected to e-mail devices that have the ability to record voices electronically and forward them to any destination.

(Problems to be Solved by the Invention) As explained above, in the conventional automatic switching device, in order to eliminate the unresponsive state of all terminal devices in a representative group, it is necessary to increase the number of terminal devices. This will not only increase costs but also lead to a decline in service.

The purpose of the present invention is to select a small representative group as one terminal device as a large representative group, although it is independent as a small representative group, and also select a common representative of one terminal device. Eliminate mutual independence, and when all terminal devices in a sub-representative group are unresponsive, incoming calls can be forwarded to other sub-representative groups, improving efficiency and service, and does it require additional terminal equipment? It is an object of the present invention to provide a representative group selection device in an automatic switching device, which enables economical cost reduction.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides means for configuring a plurality of terminal devices connected to an automatic switching device as a small representative group, and a means for configuring a plurality of small representative groups as a large representative group. means for configuring the terminal devices as a group; and a means for selecting a small representative group within the large representative group in conjunction with selecting a representative of the terminal devices within the small representative group; and means for configuring it so that.

(Operation) According to the present invention, when a plurality of terminal devices are configured as a small representative group, and a plurality of small representative groups are configured as a large representative group, and an incoming call occurs to a predetermined terminal device, When the corresponding terminal device is unable to respond, the free terminals within the small representative group are sequentially searched, and if no free terminal device is found within the small representative group,
The next small representative group is extracted from the large representative group configuration, and an empty terminal within the corresponding small representative group is searched again.

As a result, even if you are unable to answer an incoming call to your own department, you can have another department answer the call.

Furthermore, when a terminal device is configured to be common to a plurality of representative groups, a centralized proxy response can be made when an incoming call to any of the representative groups cannot be answered.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a representative group selection device of an automatic switching device in an embodiment of the present invention.

In FIG. 1, a portion surrounded by a broken line indicated by reference numeral 10 constitutes an automatic switching device.

This automatic switching device 10 consists of a communication path switch 11 and various elements connected around it.Among these elements, the ones that are particularly important for this embodiment are: A central processing unit (CPtll 12 and a storage device (MEM) connected to the communication path switch 11
) 13, a central office trunk (COT) 14 connected to another PBX or central office line, and a plurality of telephones or extension terminals 15.

In the above configuration, the storage device 13 stores a program for the central processing unit 12 that controls this automatic exchange system,
Various data required for its control are stored. Further, an input/output device 16 is connected to the central processing unit 12, and various data can be registered therein.

FIG. 2 shows a list of small representative groups that constitute a representative group of a plurality of terminal devices in order to implement the present invention. The extension representative selection type and the office line representative selection type 20 are a selection method that searches for an empty terminal within a small representative group for an incoming call from an extension, and a selection method that searches for an empty terminal within a small representative group for an incoming call from a central office line. This shows a selection method for searching for a terminal, and the selection method will be explained using FIG. One small representative group is made up of a plurality of terminals on the small representative group selection line 22 in order from the small representative group selection line 21 and the small representative group final display 23.

Similarly, regarding the large representative group list, as shown in FIG. It consists of a display 33.

The small representative group list and large representative group list explained above are
It is stored in the storage device 13 and managed and controlled by the central processing unit 12.

Furthermore, the registration operation of this list is performed by inputting data such as commands from the input/output device 16 connected to the central processing unit 12, and in this embodiment, there are no particular limitations on the registered devices and operations.

Next, the representative selection method described above will be explained using FIG. 4. There are four main types of empty copy selection methods for one representative group.

The crossbar method shown in FIG. 4, 13j is one in which sub-extensions are sequentially searched only when there is an incoming call to the parent extension.

In addition, the switchback method shown in FIG. 4fb) sequentially searches for vacant child extensions not only for the parent extension but also for incoming calls to the child extensions.

The termination method shown in FIG. 1(j) is such that the search for an empty extension starts from the extension where the incoming call occurred and stops at the last sub-extension in the representative group list.

Furthermore, the cyclic method shown in FIG. 4, 13j is a method in which the number of calls received is distributed so that the number of calls received is equal within one representative group.

Although other representative group selection methods are conceivable, the present invention specifies the representative group configuration, and the representative group selection method is not particularly limited.

In the following, a description will be given of the incoming call form when a small representative group and a large representative group are configured.

FIG. 5 shows the transition of an incoming call when the extension 100 calls the parent extension 200 of the small representative group 1.

As shown in FIG. 7, the sub-representative group 1 has a crossbar type extension representative selection type and is configured with a parent extension 200 and child extensions 201 and 202, and small representative group 2 also has a parent extension 300 and a child extension 3.
It consists of 01 and 302.

Further, as for the large representative group, as shown in FIG. 8, it is composed of the parent extension line 200 of the small representative group 1 and the parent extension line 300 of the small representative group 2.

Here, in response to an incoming call from extension 100 to parent extension 200, when parent extension 200 is busy, central processing unit 12
extracts the small representative group 1 from the small representative group list stored in the storage device 13.

For small representative group 1, the extension representative selection type is the crossbar method,
Since extension 200 is the parent extension, the next child extension is checked for availability until the final display of sub-representative group 1 is detected.

If all child extensions are in use, central processing unit 1
2 refers to the large representative group list stored in the storage device 12. In the large representative group list, next to the parent extension 200 of the small representative group 1, the parent extension 300 of the small representative group 2 is set as a child extension of the large representative group.

Therefore, the central processing unit 12 refers to the small representative group list again and extracts the small representative group 2. Similarly, for the small representative group 2, a vacant extension is searched according to the extension representative selection type, and if the main extension 300 is vacant, the incoming call is accepted.

Next, the transition of an incoming call from a central office line trunk will be explained using FIG. 6.

In response to an incoming call from the central office line trunk 14 to the sub-extension line 201 of the sub-representative group 1, when the sub-extension line 201 is in use, the central processing unit 12 selects a sub-representative group list smaller than the sub-representative group list stored in the storage device 13. Extract representative group 1.

Since the selection type of representative line in the small representative group 1 is the switchback method, the process goes around within the representative group until an empty extension line of the small representative group 1 is detected.

If all child extension lines are in use, the sub representative group 1
The parent extension 300 of the next small representative group 2 is extracted by referring to the large representative group list based on the parent extension 200 of . Central processing unit 1
2 refers to the small representative group list again based on the parent extension 300 and extracts the small representative group 2.

Similarly, for the small representative group 2, a vacant extension is searched according to the selection type of central office line representative, and if the main extension 300 is vacant, the incoming call is accepted.

As described above, by configuring a small representative group as a large representative group, it becomes possible to have another receptionist answer an incoming call that cannot be handled by a certain receptionist.

Next, the incoming call transition when the same extension is configured across a plurality of representative groups will be explained using FIGS. 9 and 10.

Small representative group 1 uses extension 400 as the parent extension and child extension 401.
.

First, in response to an incoming call from the office line trunk 114a to the main extension line 400, when the main extension line 400 is in use, the central processing unit 12 refers to the sub-representative group list stored in the storage device 13, and Extract group 1.

The small representative group 1 is the station line representative selection type or the crossbar method,
Since extension 400 is the parent extension, the next child extension 401
It manually checks the availability of the terminal and accepts incoming calls if it is available.

Similarly, regarding an incoming call from the office line trunk 214b to the main extension line 500, if the main extension line 500 is in use, the small representative group 2 is extracted from the small representative group list, and the small representative group 2 is extracted from the small representative group list.
Checks the availability status of the next child extension until the final display of is detected. If the sub-extension line 402 is free, the incoming call is accepted.

As described above, if the same child extension line can be configured to span multiple representative groups, it becomes possible to have the secretary common to the executives answer on their behalf when the executives are talking.

The above has described an example of a telephone exchange, but the configuration of a plurality of small representative groups is such that when all facsimile terminals in a small representative group consisting of facsimile IJ terminals are unresponsive, the line is configured to accommodate facsimile mail equipment. It is also effective for facsimile terminal proxy services when incoming calls are diverted to a small group of representatives.

With reference to FIGS. 11, 12, and 13, the transition of an incoming call to the facsimile mail device during a conversation on the facsimile terminal will be explained.

FIG. 12 shows the configuration of a small representative group of facsimile terminals (FAX) and a small representative group of facsimile mail equipment (MAIL) accommodation lines.
600 is configured as a parent extension, and FAX 601 is configured as a child extension.

The small representative group 2 uses the MAIL accommodation line 700 as the parent extension line,
MAIL 701 and 702 are configured as child extension lines.

For small representative group 3, FAX 800 is the main extension line, and FAX 8
01 is configured as a child extension. The representative selection type for each of the small representative groups is the switchback method.

Figure 13 shows a small representative group 1.3 consisting of facsimile terminals.
This figure shows the structure of the small representative group 2 consisting of the facsimile mail receiving line and the small representative group 2. The large representative group 1 has the facsimile terminal small representative group 1 as its parent, and the facsimile mail receiving line small representative group 2 as its parent. configured as a child. The large representative group 2 has a small representative group 3 of facsimile terminals as its parent, and is configured in advance by straddling the large representative group 1 with the small representative group 3 of facsimile mail receiving lines. Both types of representative selection are based on the crossbar method.

In the small representative group and large representative group configurations as described above, when the incoming call to the FAX 600 from the office line trunk 1 14a cannot be answered, the central processing 12 uses the small representative group list stored in the storage device 13. Then, the sub-representative group 1 is extracted, and an empty FAX currently being registered as the next child extension is searched.

If all FAXs in the small representative group 1 are unable to respond, MAIL 700, which is registered as the parent extension of the next small representative group 2, is extracted from the child extensions of the large representative group 1 from the large representative group 1 to 1.

The central processing unit 12 uses the parent extension MAIL 70 of the small representative group 2.
The sub-representative group 2 is again extracted from the sub-representative group list based on the sub-representative group 0, and in the same way as the search for the sub-representative group 1, a vacant M A I L line in the sub-representative group 2 is searched.

If a free MAIL line is found, the incoming call will be accepted. In addition, FAX8 from the central office line [・Rank 214b]
If FAX 800 is unable to respond to an incoming call to 00, the sub-representative group 3 is selected from the sub-representative group list as described above.
If all the faxes are unresponsive, search for the next small representative group 2 from large representative group 2 in the large representative group list.
is extracted, and the empty M in the small representative group 3 of the small representative group list is extracted again.
Search for AIL lines. If there is a free MAIL line, the incoming call will be accepted.

As a result, when the facsimile terminal is in the middle of a conversation, incoming calls can be diverted to the facsimile mail device, making it possible to implement a proxy service.

In addition, if the large representative group is composed of a small representative group consisting of the faxes of your department, a small representative group 2 consisting of MATL lines, and a small representative group 3 consisting of the faxes of other departments, all the faxes of your department If you are unable to respond and all MAIL lines are blocked, you may be asked to use another department's fax to respond on your behalf.

(Effects of the Invention) As described above, according to the present invention, in a Nostem that automatically exchanges a plurality of terminal devices, the plurality of terminal devices are configured as a small representative group, and the plurality of small representative groups are configured as a large representative group. Now, when all the terminal devices in a sub-representative group are unresponsive, the incoming call can be transferred to another sub-representative group.
As efficiency improves, so does service.

Furthermore, since the same terminal device can be configured across a plurality of representative groups, there is no need to add unnecessary terminal devices, leading to an economic cost reduction.
