Abstract

PURPOSE: To attain operation through a key telephone set being an optional terminal equipment by setting an output voice level from an optional paging output section in a prescribed operation designating a sound volume level in succession to a paging operation. CONSTITUTION: A control section 11 of a master set 1 is a component of a speech network of key telephone sets 2(1)-2(6) via a telephone set interface section 12 and a desired output sound level is set to a paging sound output section by the operation of a prescribed key provided in an optional key telephone set. For example, after internal paging operation from the key telephone set 2(1), a predetermined operation such as dialing of '2' is made, a paging operation signal is sent to the control section 11 via the telephone set interface section 12 to execute paging function to other key telephone sets being paging output sections and a command to set an output sound level of each key telephone set to a corresponding level is sent to the key telephone sets 2(2)-2(6).

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,
Particularly, the present invention relates to a key telephone device that simplifies the setting operation of the paging output voice level.

[0002]

2. Description of the Related Art A plurality of key telephones are connected via a main unit, and a CPU and a telephone network control unit in the main unit constitute a channel for the button telephone to an outside line and a channel for communication between the plurality of key telephones. In the key telephone device that is used,
Various CPU operations can be executed by the CPU of the main unit.
For example, the call time and call charge data may be displayed on a display such as an LED installed in each button telephone, and the called party may be called from one button telephone using a speaker installed in an arbitrary part of the premises. On-premise broadcasting, when receiving a call,
Often a function is provided to control the ringing button telephone.

In the paging function of this type of key telephone device, the volume and level of output voice are performed by the respective voice output sections. That is, the volume level of the output voice is adjusted by operating the volume adjusting knob of each button telephone or the external speaker.

[0004]

However, the environment,
It is difficult to always set the key telephone or the external speaker as the paging output unit, which is installed in a place where the ambient conditions are different, as the paging output unit, to the best condition. For example, when a key telephone or an external speaker is installed in the factory and office, ambient noise is large when the factory is operating, and the paging output sound is hard to hear, and the called party may not notice the call. Many. At this time,
The volume control knobs of the button telephone and the external speaker have to be individually adjusted, which is complicated. Also, the ambient noise condition changes every moment, so each time the condition deteriorates,
Individual adjustment is very complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a button telephone device which has an improved operability by allowing the button telephone as a terminal to easily adjust the output voice level during paging.

[0006]

In order to solve the above-mentioned problems, the key telephone device of the present invention is such that a main unit and a plurality of key telephones are connected to each other, and a paging output section is provided by a paging operation from one key telephone. In a key telephone device that executes a paging operation via a key telephone or a speaker, an arbitrary paging output unit of the key telephone or the speaker is operated by a predetermined operation that specifies a volume level subsequent to the paging operation from the one key telephone. Configured to set the output audio level from.

[0007]

According to the present invention, the paging operation is performed when the paging operation is performed through the button telephone or the speaker as the paging output unit by the paging operation from one of the plurality of key telephones connected to the main device. The audio output level from an arbitrary paging output unit is set by a predetermined operation for designating the volume level subsequent to.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a schematic block diagram showing an embodiment of a key telephone device according to the present invention.
internal) represents an example of application to paging.

In this embodiment, six key telephones 2 (1) to 2 (6) are connected to the main unit 1, and the control unit 11 of the main unit 1 controls each button via the telephone interface unit 12. A telephone line network of the telephones 2 (1) to 2 (6) is configured, and a paging voice output unit is set to a desired output voice level by operating a predetermined key provided on any button telephone. For example, after performing an internal paging operation from the key telephone 2 (1) and dialing a predetermined operation, for example, "2", the paging operation signal is sent to the control unit 11 via the telephone interface unit 12, Performs the paging function for other button telephones as the paging output section, and then
A command for setting the output voice level of each button telephone set to a level corresponding to the transmitted output voice level "2" to be set is displayed on the other button telephones 2 (2) -2.
Send to (6).

FIG. 2 is a block diagram of another embodiment of the present invention, showing an example of application to an external paging function. In this embodiment, the key telephone 2
In this example, the output sound level of the external speaker 3 (1) is adjusted by the operation from (1). That is, when a predetermined external paging operation is performed on the key telephone 2 (1) side,
This operation signal is sent to the control unit 11 via the telephone interface unit 12, and under the control of the control unit 11, the external paging interface unit 13 sets the output voice level of the external speaker 3 (1). By a subsequent operation for setting the output sound level of the key telephone 2 (1), for example, a dialing operation of "2",
A signal corresponding to "2" is sent to the control unit 11 via the key telephone interface unit 12, and the audio level output from the external speaker 3 (1) is set via the external paging interface unit 13.

As described above, according to the present invention, the output voice level of the key telephone or the speaker as the voice output unit can be adjusted by the predetermined operation from the predetermined key telephone among the key telephones connected to the main device. Has been done. Note that the button telephones that enable the output voice level adjustment operation may be all the button telephones connected to the main device, or any button telephone or speaker may be specified to adjust the individual output voice level. You can also do it.

[0012]

As described above, according to the key telephone device of the present invention, the output voice level from the voice output unit during paging operation can be controlled from the key telephone as an arbitrary terminal. Become.
