Abstract

PURPOSE: To provide the key telephone unit capable of discriminating various lines without sticking a seal or the like on each of push buttons for lines corresponding to various lines. CONSTITUTION: When detecting that one of lines A, B, and C connected to a channel switch system 5 is idle, a main device control means 7 of a main device 2 refers to corresponding data of line classifications of lines A, B, and C stored in a storage means 6 to transmit an idle state display control signal to a telephone set control means 11 of a key service unit 1. The telephone set control means 11 displays a lamp 4a, 4n, or 4c of the corresponding line in a prescribed form through a display means 10 based on the idle state display control signal from the main device 2. For example, the lamp corresponding to the line A is not displayed, and that to the line B is uniquely flickered in red, and that to the line C is uniquely flickered in green.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button telephone device accommodating various lines such as an outside line and an extension line.

[0002]

2. Description of the Related Art As a button telephone device of this type, a private telephone line (station line), an extension using a private branch exchange (PBX) used in a business office such as a company, or an exclusive use in an administrative institution, for example. Some have various lines, such as a dedicated line using a dedicated telephone network with a line exchange installed.

In such a key telephone device, a line push button corresponding to various lines is provided, and when using various lines, a vacant state (waiting for incoming call) to be used
A sticker is attached to each line push button so that the line can be specified.

[0004]

Since the conventional button telephone device is constructed as described above, it is necessary to perform a troublesome work of attaching a sticker or the like to each line push button corresponding to various lines. . Usually, the space for sticking such a sticker is limited, and in many cases the characters of the line type written on the sticker have to be written with symbols. For example, if the user is in the same department, there is no problem, but if a person in another department uses it, it may not be possible to determine the idle line. Also, when the accommodation line is changed, it is necessary to replace the sticker.

The present invention has been made in order to solve the above-mentioned problems, and can be applied to various types of unused lines without attaching a sticker or the like to the line push buttons corresponding to various types of lines. It is intended to provide a key telephone device capable of making a distinction.

[0006]

A key telephone device according to the present invention is provided in correspondence with an incoming call waiting state detecting means for detecting that various lines such as an outside line and an extension line are in an incoming call waiting state, and the various lines. And a control means for changing the lamp display on the line push button to a different display form for each line, depending on the line push button capable of displaying the lamp and the waiting state of the various lines detected by the waiting state detecting means. It is configured to have and.

[0007]

In the key telephone device according to the present invention, the incoming call waiting state of each line is made different for each line as the display form by the lamp display on the line push button. It is possible to identify various lines that are waiting for an incoming call without attaching a sticker or the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of a button telephone device showing an embodiment of the present invention. In the figure, (1) is a key telephone, and (2) is a main device to which a plurality of the key telephones (1) are connected. A plurality of (here, three) lines are connected to the main device (2). The line (A) is a general subscriber telephone line, the line (B) is a PBX extension line, and the line (C) is a dedicated line. The button telephone (1) is provided with line push buttons (3a), (3b), (3c) corresponding to these three lines (A), (B), and (C). (3a), (3b) and (3c) are provided with display lamps (4a), (4b) and (4c), respectively.

FIG. 2 is a functional block diagram of the key telephone device described above. Three lines (A), (B), (C)
Are connected to the speech path switch system (5) in the main device (2). The call path switch system (5) is a part having an exchange function for making a call between the key telephone (1) and each line (A), (B), (C) through the voice signal line (Sv). , A speech path switch, a microprocessor and a crosspoint switch.

In the main unit (2), (6) is a storage means for storing system data related to the entire system, such as correspondence of line types in lines (A), (B) and (C). (7) is a main device control means, which is mainly composed of a microprocessor. The main device control means (7) is a part that controls the entire system for operating the main device (2), and each line (A),
(B) and (C) function as an incoming call waiting state detecting means for detecting that the incoming call waiting state is established. The control program in the main device (2) is built in the microprocessor of the main device control means (7) or stored in the storage means (6).

In the key telephone (1), (8) is a communication circuit, (9) is input means, (10) is display means, and (1)
1) is a telephone control means. The call circuit (8) sends the voice signal input via the main unit (2) to the transmitter or speaker (13) of the handset (12) and from the receiver or microphone (14) of the handset (12). The input audio signal is sent to the main device (2).

The input means (9) is a telephone control means (1
Push button (15) according to the scan data from 1)
The pressed state of is converted into a signal that can be read by the telephone control means (11) and transmitted. The display means (10) includes display lamps (4a), (4b), from the telephone control means (11),
Based on the display control signal for (4c), the display lamp (4) of any of the corresponding lines (A), (B), (C)
Display a), (4b), and (4c) in a predetermined form. That is, the display means (10) and the telephone control means (1
With 1), push buttons for lines (3a), (3b), (3
The lamp display in c) is displayed on each line (A), (B),
(C) constitutes a control means which has a different display form.

The telephone control means (11) is mainly composed of a microprocessor, and the control data from the main unit (2) through the control signal line (Sc) and the push button input through the input means (9).
