Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange connection method for automatically converting a public number to a private line number in order to effectively use a private line network during telephone exchange, particularly when a private branch exchange is operated.

[0002]

2. Description of the Related Art Private branch exchanges (hereinafter also referred to as PBXs) are connected by a leased line network or the like because the usage cost is lower than that of a public network. If both the private line network and the public network are connected between the PBXs, the connection can be made using either the private network or the public network. However, if the private network is used as the transmission method, the private network is designated. And the leased line number are specified, and in the case of a public network, the public number of the other party is specified. FIG. 2 is a diagram showing a conventional PBX connection method. Hereinafter, a conventional connection method between PBXs will be described with reference to FIG. PBX
When both the private line network 3 and the public network 4 are connected between the PBX 1 and the PBX 2, the caller selects either the private line network 3 or the public network 4 with the telephone 5 and the other party The dedicated line number (for example, 31-2000) or the dial-in number (for example, 03-3452-4000) of the telephone 6 is transmitted. In the PBX 1, either the leased line network 3 or the public network 4 is connected according to the selection of the caller, and communication is performed through the connected network.

[0003]

However, in the conventional connection method between PBXs, when a dedicated network is newly provided in the system, the user does not know the existence of the dedicated line network, or Even if we were aware of the existence, there was a problem that we could use the public network even though we had a leased line network because of our previous customs.

[0004]

In order to solve the above problems, the first invention executes the following processing in a private branch exchange connection method in which both a public network and a private line network are connected. That is, a conversion data creation process for creating conversion data for converting a public number to a dedicated line number, and when the public number is dialed, the conversion data is searched for,
If there is a dedicated line number corresponding to the dialed public number, conversion processing for connecting the dedicated line network is executed. According to the first aspect of the present invention, since the connection method of the private branch exchange is configured as described above, conversion data for converting the public number to the leased line number is created by the conversion data creation process, and the public number is dialed. Then, the conversion data is searched, and if there is a leased line number corresponding to the dialed public number, the leased line network is connected. Therefore, the above problem can be solved.

[0005]

1 is a system configuration diagram for carrying out a method of connecting a private branch exchange according to an embodiment of the present invention. The difference between the PBX connection method of this embodiment and the conventional PBX connection method is that the conversion data creating means 11 creates conversion data for converting the public number of the public network 40 into the dedicated line number in the PBX. And a conversion means 12 for converting the public number of the public network 40 into a dedicated line number, and the public network 4
Even if the public number of 0 is sent by the caller, the private line network 30 is connected if the private line number is registered. As shown in FIG. 1, both the private line network 30 and the public network 40 are connected between the head office PBX 10 and the branch PPB 20. The head office PBX 10 is provided with conversion data creating means 11 for creating conversion data for converting a public number into a dedicated line number, and conversion means 12 for automatically converting a public number into a dedicated line number. The conversion data creating means 11 and the conversion means 12 are
For example, a central processing unit (hereinafter, CP) in the head office PBX10
(U)). The input side of the conversion means 12 is connected to an extension circuit (not shown) connected to the telephone 13, and the output side is connected to a private line trunk (not shown) connected to the private line network 30 and a public network 40. Not connected to the trunk for trunk lines. In the branch office PBX20, in the leased line network 30,
The private line trunk (not shown) and the public network 30 are connected to an office line trunk (not shown), and the telephone line 21 is connected to the private line trunk and the office line trunk through a CPU (not shown) and an extension circuit. There is.

3 (a) to 3 (c) are diagrams showing public number private line conversion translation data, and in particular, FIG. 3 (a) is an overall configuration diagram of public number private line conversion translation data, and FIG. ) Is a record corresponding to each dial digit number, and FIG. 7C is a diagram showing items provided for each dial digit. As shown in FIG. 3A, the public number leased line conversion translation data is composed of a plurality of records (the maximum number of records is XXXX) corresponding to each dial digit. ), It is made up of 10 items indicating the type of numbers of dial digits. As shown in FIG. 3C, each record includes TYP and NRE.
It is composed of two items, C / PVP. TYP
Is an item that indicates the status of the record, empty = 0 (there is no dedicated line number corresponding to the public number), continue = 1 (still in the process of conversion, and it is necessary to judge by the dial digit of the next digit). Yes), decision = 2 (dedicated line number corresponding to public number is determined), end = 7 (go to last dial digit but there is no dedicated line number to convert). NREC is an item indicating the start address of the record of the next dial digit when TYP = 1, and 0 ≦
Take a value of NREC ≦ XXXX. PVP is TYP = 2
At this time, it is an index indicating the storage address of the corresponding public number to the public line dedicated line number conversion registration data. Here, the PVP is set because if the dedicated line number is inserted instead of the PVP, the item size at the time of determination becomes large and the record size is not constant, making control more complicated than when the record size is constant. Because it will be. Also, if the size of the item is made constant according to the item size at the time of determination, memory is wasted.

[0007] FIG. 4 is a diagram showing public line dedicated line number conversion registration data. As shown in FIG. 4, the public number leased line number conversion registration data is composed of records for the leased line numbers, and each record indicates the leased line number and is indexed by the PVP of the public number leased line number translation data. There is. FIG. 5 is a flowchart showing the flow of public number dedicated network number translation. Hereinafter, the connection method ((a) to (c)) of the private branch exchange will be described with reference to these drawings. (A) Creation of Public Number Dedicated Line Number Registration Data The conversion data creation means 11 creates the public number dedicated line number conversion registration data shown in FIG. 4 and stores it in a recording medium such as a memory. This is the dedicated line number you want to register 1
It may be created by additionally registering each piece, or may be created by another method.

(B) Creation of Public Number Dedicated Line Number Translation Translation Data The conversion data creating means 11 creates the public number dedicated line number translation data shown in FIG. 3 and stores it in a recording medium such as a memory. . This may be created by initializing the memory used by the public number dedicated line number translation data to 0 and additionally registering it as described below, or by another method. To register additionally,
From the first digit of the public number to be registered, the record corresponding to that dial digit (the first digit record is 0
And the next record is the item's NRE
(Indexed by C). Then, the item corresponding to the dial digit in the record of the dial digit is checked, and when TYP = 0, the memory area is reserved for the record of the next dial digit, and the item TYP = 1, the item NREC = the address of the secured record area, and TYP = O of all the items in the secured record. For the item of the last dial digit, set TYP = 2, and set the PVP of the registered dedicated line number (set TYP = 7 for items other than TYP = 2). (C) Conversion processing When a caller dials a public number from the telephone 13, the public number dialed is sent from the extension circuit to the conversion means 12. The conversion unit 12 retrieves the public number dedicated line number conversion translation data created by the conversion data creating unit 11 and converts the public number dedicated line number registration data into the corresponding dedicated network number.

The conversion process will be described in detail below with reference to FIG. As shown in FIG. 5, in step S1, NREC = 0 and the first digit of the public number input by the caller are indexed by DS-1. In step S2, the head record of the current dial digit is indexed by NREC, and the item is indexed by DS-1 from DS-1 from the head record. For example, when the current dial digit is the first digit,
The first record is obtained with NREC = 0, and 1 is obtained with DS-1.
You will get the item with the digit in the first digit. In step S3, the TYP stored in the item indexed by NREC and DS-1 is checked. When TYP = 1 (continue), the process proceeds to step S4, and when TYP = 2 (decision), the process proceeds to step S5 and TYP = 0, 7
If (empty, end), the process proceeds to step S6.

In step S4, the dial digit of the next digit is input to NREC = NREC in the item, DS-1. The record at the beginning of the next digit is indexed by NREC, the item corresponding to the dial number at the beginning of the next digit is indexed by DS-1, and the next digit is set as the current dial digit. Return. In step S5, since the translation is determined, the PVP in the item is obtained, the public number leased line number conversion registration data is indexed by the PVP, and the leased line number corresponding to the dialed public number is obtained. Then, the leased line network 30 is connected and the leased line number is transmitted to the branch office PBX 20 via this leased line network 30. At the branch office PBX 20, call the telephone 21 having the corresponding leased line number,
A telephone call is made between the telephones 13 and 21 via the leased line network 30. In step S6, since the public number dialed in does not have the leased line number, or does not have the leased line number, the public number is connected through the public network 40, and the telephone 13 of the head office PBX 10 and the branch PBX 20 are connected. Telephone 21
Control to talk to and from.

FIG. 6 is a diagram showing a connection in which a public number is converted into a leased line number. The broken line in FIG. 6 is the conventional connection route, and the alternate long and short dash line is the connection route by the conversion means 12 of this embodiment. As shown in FIG. 6, for example, from the telephone set 13 of the caller, the public number of the public network (for example, 03
-3452-4000) is dialed, the private line network is connected by the conversion means 12 of the head office PBX 10, and the private line number 2000 (31-20 of PBX station number 31).
00) is transmitted to the leased line network 30 to talk with the partner telephone 21 using the leased line network 30. FIG. 7 is a diagram showing a connection to an extension not accommodated in the leased line network. As shown in FIG.
When the public number (for example, 03-3798-2222) is designated, the designated public number is used for the leased line network 30.
When it is not registered in the public number dedicated line number translation data because it is not accommodated in, the public network 40 is connected and the public number is transmitted to the branch office PBX 20.

As described above, according to this embodiment, in a system provided with a leased line network, there is a leased line network according to previous customs even if the user does not know how to use the leased line network. Nevertheless, even for users who have used the public network, the public number is automatically converted into a dedicated line number and the dedicated line is automatically used. This allows
The economics of the network increase. Further, since the conversion data for converting the public number to the dedicated line number is divided into the public number dedicated line number translation data and the public number dedicated line number conversion registration data, the memory area is not wasted and the process is simplified. be able to. Note that the present invention is not limited to the above embodiment, and various modifications are possible. For example, there are the following modifications.

(1) In the embodiment, the example in which the head office PBX has the conversion function has been described, but all the PBXs may have the conversion function. (2) In this embodiment, the head office PBX 10 and the branch office PBX
Although a case has been described where a telephone call is made between the telephone set 13 and the telephone set 13 and 21, the other party may be a fax machine, a data terminal, or the like. (3) In the embodiment, both parties making a call are applied to the connection of the system on the leased line network, but even if one of them is not on the leased line network, the route with the lowest charge in the connection process is used. Economic efficiency can be further increased by using the function such as automatic selection and partial connection via a dedicated line. (4) In the present embodiment, the case where the public number of the area code is dialed has been described as an example, but the local application code may be added by the upper application and the conversion process may be executed again. .
