Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring network system in a building such as a commercial building.

[0002]

2. Description of the Related Art Recently, in commercial buildings, in addition to electrical equipment such as lighting equipment, due to intelligentization,
Computer equipment (for example, microcomputer terminals / workstations) and terminal equipment for information and communication such as fax, modem and telephone equipment are installed side by side.
Also, ISDN has been developed and implemented as a wiring system for integrally connecting these information and communication terminal devices. As a typical example of this, an AT & T (American Telegraph and Telephone Company) prior wiring system (PDS) is known. That is, for example, as shown in FIG. 3, this is a twisted pair cable facing each floor in a building in which building communication equipment such as a data line concentrator 100, a telephone exchange 101 such as a PBX, and a wiring switching board 102 is installed. 103
Is wired, and the end of the cable 103 is connected to the workstation 105 or the telephone 1 via the outlet 104.
It is connected to information such as 06 and communication terminal equipment. Further, in the preceding wiring system (PDS), in order to support ISDN, four pairs (8 lines) of twisted pair cables are provided as basic wiring and are stretched around in the building. On the other hand, as shown in FIG. 4, the outlets 107, which are the outlets (connection ports) of signals from these wiring networks, also have four pairs of connectors corresponding thereto, and connect the floor surface, wall surfaces, and the like. It is installed in an easy place.

[0003]

Generally, the number of wires connected to a wiring network in a building is, for example, 4 lines (2 pairs) for computer equipment such as workstations, 2 lines (1 pair) for telephone equipment, or Most of them are 4 lines (2 pairs). Therefore, in the outlet as described above, the remaining 4 or 6 lines may not be used and may be wasted, but 4 pairs (8 lines)
It is uneconomical because one outlet is required regardless of whether all are used. Particularly, for example, in the case of using computer equipment and telephone equipment at the same time, two or more outlets are required, which causes a serious inconvenience. Such an inconvenience cannot be avoided in a building or the like that adopts a pre-wiring system (PDS) in consideration of ISDN in the future, which is an extremely serious problem. On the other hand, as information and communication terminal equipment,
There is an increasing need for one computer device such as a workstation and two telephone devices to be installed in one place so that two users can use them efficiently. Therefore, an outlet that can support these three devices. There are also many requests. Therefore, in view of the above-mentioned conventional circumstances, the present invention has no waste when using the 8-wire (4 pairs) outlets corresponding to the preceding wiring system (PDS) considering the future ISDN. It is an object of the present invention to provide a wiring network system capable of connecting information and communication terminal equipment.

[0004]

That is, the present invention provides an IS
In the information transmission line wiring system corresponding to DN, the outlet of the information transmission line is branched by a branch adapter according to the constituent elements of the terminal.

[0005]

In the wiring network system of the present invention, by using an adapter that branches the output port of the outlet into various branches, the wiring of 8 lines (4 pairs) is a constituent element of a terminal, for example, a computer device 1 such as a workstation.
It is possible to connect the stand and two communication devices such as a telephone with one outlet, and it is possible to easily cope with future ISDN.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a prior wiring system to which a wiring network system according to the present invention is applied. In this wiring network system, an outlet 1 of a 4-pair (8-wire) twisted pair cable 103 is connected to a terminal device ( Component) 105,1
It is configured to be branched into three ports according to 06. The branch adapter 2 is an adapter attached to an outlet of 8 lines (4 pairs) similar to the conventional one, and one outlet enables connection between the information terminal device 105 (1 unit) and the telephone set 106 (2 units). And will be explained next. 3
It is a relay connector for the individual connectors 3A to 3C.

That is, in the branch adapter 2 of this embodiment, as shown in FIG.
It is connected to (terminal numbers 4 and 5). Further, the twisted pair cables 103 whose wire numbers are 3, 4, 5 and 6 are connectors 3B (terminal numbers 1, 4) for an information terminal device 105 such as a workstation having a 4-wire input / output correspondence.
2, 3, 6). Further, the twisted pair cables 103 having wire numbers 7 and 8 are connected to the communication connector 3C (terminal numbers 4 and 5) for another telephone set 106.

Therefore, according to this embodiment, all the cables of the preceding wiring provided for future consideration are effectively used, and the cables are not wasted. In addition, when connecting an 8-wire (4 pairs) device in the future, all you have to do is remove the branch adapter 2, and it will be compatible with ISDN, etc.
And it can be performed easily.

[0009]

As described above, according to the network system of the present invention, by using the adapter for branching the output port of the outlet in various ways,
Eight wires (4 pairs) can be connected to a component of a terminal, for example, one information terminal device and two telephones, which are often requested by users, with one outlet, and all cables can be utilized without waste. It is economical. Moreover, according to the wiring network system of the present invention, it is possible to easily cope with future ISDN and the like simply by removing the branch adapter.
