Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone switching system controlled by a so-called CPU, such as an electronic button telephone device, in which system data is written to a specific extension. This invention relates to a method for identifying the above-mentioned specific extension telephone in a system that can be operated from a telephone.

[Prior art]

2. Description of the Related Art In a telephone exchange system such as an electronic key telephone device, a method is known in which system data, such as when changing an extension number, is written online using a specific extension telephone.

In a telephone exchange system that uses such a system data writing method, a specific extension telephone used for writing system data is used as a normal extension telephone except when writing data.
Moreover, since the hardware configuration is exactly the same as a general extension telephone, it is impossible to distinguish between the specific extension telephone and the general extension telephone. For this reason, in the past, the specific extension telephone for writing system data was recorded in an extension number memo, the specific extension telephone was displayed by operating a write key switch, or a mark was placed on the specific extension telephone. The specific extension telephone is identified from among the many extension telephones.

[Problem that the invention seeks to solve]

The accommodation terminal of the extension telephone in the telephone exchange system and the extension number are generally not fixed, and the extension number can be freely set by changing system data. Therefore, if the specified extension telephone is identified by recording an extension number memo or by attaching a mark to the telephone, it is necessary to change the record or replace the mark when changing the extension number. If these are not done correctly, the specific extension telephone will not be able to be identified. In addition, when identifying the above-mentioned specific extension telephone by operating the write key switch, it is necessary to go to the telephone exchange system installation location and locate the displayed extension telephone each time data is to be written. Initial work for write operations becomes troublesome.

The present invention is proposed to solve the above-mentioned problems, and is to provide a system data writing telephone that can identify a specific extension telephone for system data writing without providing a means for identifying it. The purpose is to obtain an identification method.

[Means for solving problems]

For the above purpose, the present invention provides that when any of the extension telephone receiving terminals of a telephone exchange system is set for writing system data, the terminal set for writing system data has an extension that cannot be changed by the system data. A number is fixedly assigned, and the telephone to which the system data is written can be identified by the extension number.

[Embodiments of the invention]

FIG. 1 is a diagram showing a system according to an embodiment of the present invention, and FIG. 2 is a diagram showing an extension number table of the embodiment shown in FIG.

In Figure 1, EX is a telephone exchange system,
TEL ₁ to TEL _o are extension telephones, a ₁ to _{a o} are extension telephone accommodation terminals (hereinafter referred to as terminals) of the telephone exchange system EX, CCU is a processing unit mainly composed of a so-called one-chip CPU, and TB is a RAM. configured,
An extension number table stores the correspondence between terminals _a1 to _ao and extension numbers, and SW is a deep switch for setting a system data write terminal.

As shown in FIG. 2, the extension number table TB has extension number storage areas corresponding to terminals a ₁ to a _{o .} In the example shown in FIG _. The extension numbers of telephone extensions TEL ₁ to _{TEL o} are "311", "223", "210", respectively.
It is set to “135”.

Among the above extension numbers, for example, "210" (the number marked with *) is a number fixedly assigned to the system data writing terminal. In other words, if, for example, terminal _A3 is set as the system data write terminal using the deep switch SW, the processing device
The CCU stores the fixed extension number “210” in the extension number storage area corresponding to terminal a ₃ of the extension number table TB.
Store. As a result, the extension number of extension telephone TEL ₃ is set to "210", and this extension telephone
TEL ₃ becomes a specific extension telephone for writing system data. Further, the extension number "210" assigned to this specific extension telephone (TEL ₃ in the example of FIG. 1) is a fixed number that cannot be changed depending on the system data.

Terminal set for writing the above system data
For terminals a ₁ , a ₂ , ... a _o other than a ₃ , the respective extension numbers are "311" and "311" depending on the system data.
"223", ... "135" are set. That is, extension numbers "311", "223", ... "135" are stored in the extension number storage areas corresponding to terminals a ₁ , a ₂ , ... an of the extension number table, respectively, according to the system data. Extension telephone TEL ₁ , TEL ₂ , ...TEL _o
The extension numbers are “311”, “223”, etc. respectively.
It becomes “135”. The extension numbers set by this system data (numbers other than those marked with "*" in FIG. 1 or 2) can be freely changed by changing the system data.

When inputting system data that assigns extension number "210" to a terminal that is not for system data writing, for example, terminal a ₁ (extension telephone TEL ₁ ), or when inputting system data that assigns extension number "210" to a terminal that is not used for system data writing, In the example shown in Figure 1, a ₃ )
When inputting system data for setting an extension number, the processing unit CCU performs error processing because the input of the system data is incorrect, and the specified extension telephone for inputting system data is
An error message will be displayed on TEL ₃ . In this way, the extension number “210” of the above specified extension telephone TEL ₃
The extension number "210" cannot be changed, and the extension number "210" cannot be assigned to other telephone extensions.

As described above, although the relationship between the system data write terminal and its extension number cannot be changed, the system data write terminal itself can be changed by changing the setting of the deep switch SW. In other words, for example, if you set terminal _a2 as the system data write terminal, the extension number table
The data in the extension number storage area for terminal a ₂ on the TB changes from "223" to "210", and the extension phone
TEL ₂ becomes the specified extension telephone for writing system data with extension number "210".

In addition, the extension telephone TEL ₁ accommodated in terminals a ₁ to _{a o}
~TEL _o In addition to ordinary telephones (so-called stand-alone telephones), high-performance telephones such as so-called button telephones are also used. Further, at least as the specific extension telephone, a telephone equipped with a push-button dial (however, the format of the dial code does not matter) is usually used.

Further, in the embodiment, one specific extension telephone is used for writing system data, but it is also possible to use two or more telephones. In this case, each specific extension telephone is assigned a separate fixed extension number.

Furthermore, the terminal used for writing system data can be fixed to a specific terminal using fixed wiring, without using a bit switch.

〔Effect of the invention〕

As explained above, in the present invention, a fixed extension number that cannot be changed depending on the system data is assigned to a terminal set for writing system data. Since the extension number of an extension telephone is always constant, the specific extension telephone can be identified only by the extension number without taking any special measures, and the present invention has extremely significant effects.
