Abstract

PURPOSE:To eliminate the need for replacement of wiring at the change of layout in a room by providing a transmitter-receiver provided on the way of an optical cable or a coaxial cable installed on a ceiling face in the room and a telephone set applying transmission/reception to the transmitter-receiver with radio or light as a medium. CONSTITUTION:A communication cable 11 comprising an optical cable or a coaxial cable is installed in the ceiling face 10 in the room and the transmitter- receiver 12 of light or radio system is provided on the way of the cable 11. Then extension talking in each room or between different rooms is executed between each telephone set 22 and a transmitter-receiver 12 in each room by a light or radio system and external line talking using a public line 15 is executed with the transmitter-receiver 12 by the light or radio system. Since the talking is available by the radio system in this way, no wire replacement is required in case of the change of layout in the room.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an in-company telephone system in which internal telephone calls within a company are carried out using wireless or optical media.

(Conventional technology) An internal telephone system within a company is an important piece of equipment.

Conventionally, the i-telephone system is configured by connecting a telephone to communication wiring installed indoors, for example, on the floor.

By the way, each telephone is generally placed on each person's desk, and each time the desk on which the telephone is placed is rearranged, wiring needs to be changed, etc., and the period and cost of this work depends on the management of the company. This will be a serious loss.

(Problems to be Solved by the Invention) As described above, the conventional extension telephone system within a company has the disadvantage that a large amount of construction time and cost are required when changing the indoor layout.

This invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide an in-house telephone system that does not require any construction work when changing the indoor layout, and therefore does not require any costs. .

(Means for Solving the Problems and Their Effects) The in-house telephone system of the present invention comprises an optical cable or coaxial cable installed in the ceiling of a room, a transmitter/receiver installed in the middle of this cable, and a It consists of a telephone set that is installed at This eliminates the need for work such as wiring changes when changing the indoor layout.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The figure is a conceptual diagram showing the overall configuration of an in-house telephone system according to the present invention. Reference numeral 10 denotes a ceiling surface within π, and within this ceiling surface 10, a communication cable 11 made of an optical cable, a coaxial cable, or the like is installed. Furthermore, an optical or wireless type transmitter/receiver 12 is appropriately provided in the middle of the communication cable 111. This transceiver 12
A portion of each is exposed indoors. Furthermore, the communication cable 11 is connected to a digital exchange (digital PBX).
13 to a public telephone line 14, and also to a communication cable 11 installed in another room.

Furthermore, 20 is a floor surface in the room, desks 21 are arbitrarily laid out on this floor surface 20, and telephones 22 are appropriately installed on these desks. Each of these telephones 11
22 is capable of transmitting and receiving data to and from the transmitter/receiver 12 provided in the ceiling surface 10 in each room by optical or wireless methods.

According to such a configuration, extension calls within each room or between different rooms are performed between each telephone set 22 and the transceiver 12 using an optical or wireless method. Further, external telephone calls using the public line 15 are also carried out with the transmitter/receiver 12 by optical or wireless methods.

In this way, since the telephone system of the above embodiment allows telephone calls to be made wirelessly, there is no need to change the wiring as in the conventional case each time the indoor layout is changed. Therefore, the construction period and costs associated with the construction are unnecessary. Furthermore, since there is no need to run wiring on the floor, it is possible to completely eliminate any moldings or the like that were provided for the purpose of protecting the wiring, resulting in better aesthetics and safety. moreover,
Since the telephone is battery-powered and eliminates any wiring, it can be carried to a certain extent, which is very convenient for work.

(Effects of the Invention) As explained above, according to the present invention, it is possible to provide an in-house telephone system that does not require any construction work when changing the indoor layout, and therefore does not require the cost of construction to change the layout. .
