JPS62299155A - Retreival method for telephone set for writing system data - Google Patents

Abstract

PURPOSE:To prevent the retrieval of a specific extension telephone set from becoming impassible even if an extension number is changed by giving a fixed specific number not hanged by system data together with an extension number to an extension telephone accommodating terminal for system data writing. CONSTITUTION:A special number representing a system data write terminal is given to a terminal a1 in addition to an extension number '311'. The specific number is a number different from conventional extension numbers by combining code buttons of a dial such as '#*4'. Further, the number '#*4' is set fixedly to the terminal a1 and not changed by the system data. Since the number '#*4' is a number fixedly set to the terminal a1, even if the extension number of the extensions TEL1-TELn is changed in any way, the retrieval of the set TEL1 is attained by dialing the special number '#*4'.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention is applicable to so-called C
The present invention relates to a method of searching for a specific extension telephone in a telephone switching system controlled by a PU in which system data can be written from a specific extension telephone.

[Prior art]

In a telephone exchange system such as an electronic key telephone device, a method is known in which system data, for example 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, and the hardware configuration Since it is exactly the same as a general extension telephone, it is difficult to distinguish between the specific extension telephone and the general extension telephone.

Conventionally, methods for finding a specific extension phone for writing system data from a large number of extension phones include recording the extension number of the specific extension phone in a memo, etc. (hereinafter referred to as the first method), and in-vehicle fK writing. A method (hereinafter referred to as the second method) that provides a key switch and, by operating the key switch, visually or audibly displays on the specified extension telephone that the specified extension telephone is for writing system data (hereinafter referred to as the second method); The method of adding marks (hereinafter referred to as the third method) has been adopted.

[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 first method is adopted, each time the extension number is changed, the number change of the specific extension telephone must be recorded, and if this record is not made or the record memo itself is lost, Then, it becomes impossible to search for the specific extension telephone.

In addition, according to the second method, it is necessary to install a switch on the main device, and each time you want to write data, it is necessary to visit the location where the main device is installed and also to locate the displayed extension telephone. In particular, when the main device installation location and the specific extension telephone installation location are far apart, the initial work of writing system data becomes troublesome.

Furthermore, in the third method, when rearranging telephones, if the rearrangement extends to the above-mentioned specific extension telephone, it is necessary to replace marks, etc., and there is a risk of erroneous pasting rather than troublesome markings. There is also a risk that the affixed mark may peel off.

The present invention is proposed to solve the above-mentioned problems, and an object of the present invention is to provide a method for easily finding an extension telephone for writing system data.

[Means for solving problems]

For the above purpose, the present invention provides a terminal for accommodating a specific extension telephone for writing system data, among the extension telephone accommodation terminals of a telephone exchange system, with a normal extension number (this number can be changed depending on the system data). By assigning a specific number for searching (this number is a fixed number that cannot be changed by system data), the specific extension telephone can be called by dialing the specific number from the extension telephone. It was designed so that

[Embodiments of the invention]

The drawings are diagrams for explaining the present invention in detail, in which EX is a telephone exchange system, positions 1 and 2 are extension telephones, and a and an are extension telephone accommodating terminals (hereinafter referred to as terminals) of the telephone exchange system FX. ). Here, the terminal am is a terminal for writing system data, and therefore the extension telephone device is a specific extension telephone for writing system data.

Incidentally, at least for this specific extension telephone horizontally placed, a telephone equipped with a push-button dial (however, the form of the dial code does not matter) is usually used.

As shown in the figure, terminals a1 to an are connected to terminals 311'', 223#, #456'', ~'1 depending on the system data, for example.
An extension number, such as 35', which is usually represented by only numbers, is set. This extension number is freely set according to the system data and can be changed freely.

Further, the extension telephone meter device n that accommodates the terminals a to anVc is not only a normal telephone (so-called standalone telephone) but also a high-performance telephone such as a so-called key telephone.

In addition to the above extension number '311', the terminals a and i/( are given a specific number indicating that they are system data write terminals. This specific number is, for example, "Φ*4", which is the number on the dial. A number with a format different from a normal extension number is created by combining code buttons, etc. Also, this specific number "S*4" is fixedly set to terminal a1 and cannot be changed by system data. .

When performing a new setting or change of system data, when searching for the specified extension telephone horizontally or tl, dial the specific search number "Φ*4" using either the extension telephone device or ~Th:Ln. . The dialed specific number "≠*4" is expanded into an identification code of terminal a1 by a telephone exchange system data processing device (not shown), and the terminal a1 is designated.

If the dialed extension telephone is a telephone other than the above-mentioned specified extension telephone device, for example, a ring signal is sent to the specified terminal a, and the VC incoming call is displayed at the specified extension telephone fi. (a bell rings), so it can be distinguished from other extension telephone devices. Also,
Even when the specified extension telephone device is called by a specific number “≠*4#, a communication path is set up with the called extension telephone device, so that the specified extension telephone If the device is located at a remote location, the specific extension telephone device can be easily searched for by waiting for a response and talking with the responder.

Also, if the extension telephone that dialed the specific number #φ*4'' is the specific extension telephone f! Dial the specific number #→*4# from
On the first dial, the extension telephone used for the first dial is called. ), or if it is obvious that all other extension telephones are not in use (for example, when all the extension telephones are installed in a different location), the specific extension 'direct telephone Tl2L, can be easily explored.

In addition, the extension telephone that dialed the specific number "≠*4" is a specific extension telephone device, a telephone other than , for example, TEI:L
, and a specific extension telephone-JK location.

Even if the extension telephone is busy, a busy tone is returned to the extension telephone. In this case, the other @7 and the filling machine (Th:L,
Dial the specific number "φ*4" again using a telephone other than the above, and check that the busy tone is returned. (If the busy tone is not returned, dial the first number as described above.) If the telephone used to dial the extension was a specified extension telephone Th:L, or if the specified extension a-blocking device was in a call-end state between the first and second dialing, and from the above As is clear, it is possible to search for the specific extension telephone device in any case), and the same operation can be repeated after a while.

As mentioned above, the specific number "S*4" is terminal a.

Since this is a fixed number, no matter how the extension number of the extension telephone device is changed, the search for the specific extension telephone [TEEL] can be performed by dialing the above specific number "S*4". is 6-cho Noh.

Further, in the embodiment, there is one loading extension telephone or packing machine for storing system data, but it is also possible to set two or more specific extension telephones. In this case, all the specific extension telephones that are not busy may be called simultaneously or sequentially by dialing the specific search number.

In addition, in the embodiment, the code buttons "≠" and '*" on the dial are combined as the specific search number, but if the number is represented only by numbers and the winning number is not used as the extension code, , it is also possible to use a number represented only by the numbers as a fixed number for searching (for example, Ia
If the vinegar number setting range is ``100 to 899'' K and the specific number is set as 900'') 0,
There are two ways to set the terminals used for writing system data: one is to set the only terminal aIVc by fixed wiring, and the other is to set it to one of terminals a, ~afi, etc. using a focus switch, etc. In this case, assign a specific number for searching the VC to the only terminal a above, and in the latter case, assign a specific number for searching to the terminal set for writing system data at the bit switch (actually, the specific number for searching is assigned to the terminal set for writing system data at the bit switch). (Create a program so that the terminal assigned the search time constant number becomes the system data write terminal.)

〔Effect of the invention〕

As explained above, the present invention assigns a fixed specific number that cannot be changed with the system data together with the extension number to the extension telephone insertion terminal for system data insertion of the telephone exchange system, and dials the percentage fixed number. This is designed to search for a specific telephone extension for writing system data, so that even if the extension number is changed, the fixed extension number 1 is still in use.
It does not make it impossible to search for wax, and there is no need to provide node means such as switches just for searching.This method completely solves the problems of the prior art described above, and its effects are very large. .
