Abstract

PURPOSE:To make it possible to catch the line wire trunk of its own tenant also from the extension telephone set of the other tenant to attain line wire origination by temporarily switching the tenant of the extension telephone set into a tenant registered correspondingly to an ID code by dialing the ID code. CONSTITUTION:When an originator belonging to a tenant A catches the line wire trunk 6 of its own tenant by the extension telephone set 5 of a tenant B to execute line wire origination, the originator in the tenant A dials an ID code following a specific number for inputting the ID code prior to the dialing of a telephone number. A central processing unit(CPU) 1 reads out temporary tenant information corresponding to the ID code stored in a main storage device 2 and stores the temporary tenant information in a storage area corresponding to the extension telephone set 5 of the tenant B. Although the telephone set 5 dials the specific number of line wire origination and a called subscriber's telephone number, the CPU 1 selects a line wire trunk based on the temporary tenant information. Consequently, line wire origination can be executed by using the line wire trunk of its own tenant from the other tenant.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an outside line originating system for an electronic exchange, and more particularly to outside line trunk selection based on temporary tenant information corresponding to an ID code.

[Conventional technology]

Conventionally, selection of an external line trunk when making an external line call has been performed based on tenant information given to the extension telephone that makes the external line call, and a method has been used in which a trunk belonging to the same tenant as the extension telephone is acquired.

[Problem to be solved by the invention]

The conventional outside line trunk selection when making an outside line call, as described above, relies on the tenant information on the extension phone, so when you want to capture your own tenant's outside line trunk from another tenant and make an outside line call, you can select a specific trunk by dialing. I needed to capture it.

An object of the present invention is to temporarily store tenant information in a code-compatible manner when capturing the outside line trunk of the own tenant from another tenant and making an outside line call, and to input the ID code when making an outside line call. To provide an outside line originating method that allows an outside line to be originated from a tenant using its own tenant's external line trunk.

[Means to solve the problem]

The outside line calling method of the present invention includes: a means for storing tenant information (hereinafter referred to as temporary tenant information) assigned in correspondence with an ID code; a means for reading out the temporary tenant information corresponding to the dialed ID code; It has means for storing the read temporary tenant information corresponding to the extension telephone.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a connection block diagram of an outside line transmission system according to an embodiment of the present invention.

FIG. 1 shows a central processing unit 1 that reads and processes programs stored in a main storage device 2, a main storage device 2 that stores programs and data, a main switch 3, and an extension telephone 4 of tenant A. It is composed of tenant B's extension telephone 5, tenant A's outside line trunk 6, tenant B's outside line trunk 7, and a calling register 8.

When a member of Tenant A uses the extension telephone 5 of Tenant B to capture the external line trunk 6 of his/her own tenant and make an outside call, a special number for entering the ID code is entered before dialing the telephone number, followed by the ID. Dial the code.

Following the special guide number for inputting the ID code, the dialed ID code is transmitted to the central processing unit 1 via the transmission register 8 as indicated by the arrow ▪ in FIG. The central processing unit 1 reads the temporary tenancy information corresponding to the ID code stored in the main storage device 2, and stores the temporary tenancy information in the storage area corresponding to the extension telephone 5 of tenant B as shown in (■) in FIG. Let's do it. However, it is assumed that the temporary tenancy information corresponding to the ID code is registered in the main storage device 2 in advance, and in this case, the temporary tenancy information corresponding to the ID code dialed from the extension telephone 5 of tenant B is
Assume that tenant A is registered. Next, tenant B's extension telephone 5 dials the special number for making an outside line and the called party number, but at this time the central processing unit 1
searches the temporary tenant information corresponding to tenant B from the storage area corresponding to the extension telephone 5 of tenant B in the main storage device 2,
When temporary tenant information corresponding to tenant B exists, an external line trunk is selected based on the temporary tenant information. In other words, in this case, the central processing unit 1 has set the temporary tenant information for Tenant B's extension telephone 5 in the main storage device 2 to be Tenant A, so the external call is from Tenant B's extension telephone 5. Nevertheless, only this time, tenant A's external line trunk 6 is captured and the first
As shown in the figure, the extension telephone 5 of tenant B and the external line trunk 6 of tenant A are connected via the main switch 3.

Further, when the call on the extension telephone 5 of tenant B ends and on-hook is detected, the central processing unit 1 deletes the temporary tenant information corresponding to the extension telephone 5 of tenant B in the main memory W2. As a result, the next time Tenant B's extension telephone 5
When an outside line is originated from Tenant B, the outside line trunk 7 of Tenant B is captured.

〔Effect of the invention〕

As explained above, the present invention allows you to temporarily switch the tenant of an extension telephone to a tenant registered to support ID codes by dialing an ID code. You can capture the trunk and make an outside call.

Furthermore, by using an ID card with an ID code recorded, it is not only possible to capture your own tenant's external line trunk and make an outside call even from a public facility on the premises, but you can also use the extension telephone as if it were your own tenant's extension. It has the advantage that it can be used as a telephone.
