Description

Multiple Interface Coupler And Multiple Access Communication Divide System With Local Area Network}

The present invention relates to a multiplexed access network distributed system and an interface device in a local area network, and more specifically, to a conventional UTP without additional line construction work for a data communication network by integrally forming a data connection jack in a LAN environment. The present invention relates to a method for observing the effect of installing two UTP cables with a single cable, and a distributed system capable of multiplexing multiplexed signals with a conventional UTP cable, and also to a composite interface device using the same.

With this method, you can send and receive two IP signals with one existing UTP cable, and also modify the connection jack to connect one IP signal to a computer inside one UTP cable, It is composed of a complex interface device that can connect multimedia signals to a key phone or multimedia device up to three circuits.

In recent years, in response to the information age, the demand of general telephone networks and local area networks (LANs) is gradually increasing. In addition, various communication methods with complex functions such as Internet phones have emerged.

In general, since LAN is mainly used as a data communication network, and telephone networks are mainly used for analog communication, only limited data communication using a fax transmission or a personal computer modem is possible. For example, each company installs and operates LAN and telephone in the company. In this case, LAN cable and telephone line should be connected to each individual.

On the other hand, a local area network system (LAN) is a network distribution device such as a hub that is connected to a router, a network server, or the like to provide a distributed connection function to a data communication network, and is usually a 10 base-T cable or a 100 base- Local area network interface devices (LAN cards or network adapters) are connected in a one-to-one or one-to-multiple manner through a data network line such as a 100 Base-T cable, and a host computer equipped with such a local area network interface device Data communication is performed according to protocols (CSMA / CD, DQDB, FDDI, MAC, etc. specified in IEEE 801.2, IEEE 801.2, IEEE 801.3, IEEE 801.4, IEEE 801.5, etc.).

If necessary, not only the work of dismantling or dismantling the data communication line and the multi-line is done separately, but also the construction of the construction is also done separately, so the work efficiency is reduced due to the double work. As data line management needs to be managed and maintained in duplicate, unnecessary effort and cost are incurred in securing manpower that can handle this. The rate of change in menopause that leads to poor track quality Chemistry and, cause a problem such as that the call and data transmission quality due to significantly reduced interference between the track occur is increased.

And optionally display means for displaying to the coupler externally through at least one of a visual display means and an audio display means when the data network line is electrically connected through the network connection jack. Can be.

As described above, the pin connection between the RJ-45 or RJ-11 connection jack and the RJ-45 connection jack may be made on a PCB (Print Circuit Board) or may be connected in a jumper type through a separate external wire.

On the other hand, when the multi-line is electrically coupled to the RJ-11 connection jack may be made of a signal blocking unit (not shown) to block the input of unnecessary signals applied through the multi-line inside. .

By applying this principle, various modifications using the 100 base-tee cable can be arranged and applied according to the above principle. Those skilled in the art will be able to easily make a circuit applied to the 100 base-tee cable circuit.

Therefore, using the installation method according to the present invention using only one cable in the duplex process in which the existing data communication line and the multimedia communication line had to be installed, respectively, the installation space, maintenance, and maintenance manpower while reducing air in one step. Not only can you solve the problems that caused various problems related to securing, simply and practically, but also install an additional computer within the computer working radius, and communication terminal devices (ie, telephones, fax machines, security cameras, etc.) ), You can create a simple office automation environment and computer work environment.

In the preferred embodiment of the present invention, an embodiment using a spare line is given. However, when a separate line for a telephone line is inserted in the manufacturing process of a communication cable that does not secure a reserve line, a spare line is used. The same effects as in the preferred embodiment of the present invention will be obtained.

In addition, the present invention can be implemented without the need for fundamentally technical modifications to the conventional hardware, and without adding a separate hardware resource that requires a cost, and despite the low technical difficulty for the implementation, It is well known that the ripple effects of cost savings that could occur are expected to be enormous.

In addition, the patch panel is equipped with various wiring connections to simplify the wiring and maintain the wiring easily. In addition, data transmission hubs, telephone main devices, premises broadcasting equipments, and monitoring equipments were previously produced separately. If you make a device to bundle in one place, it is an invention that can significantly lower the purchase price than when purchasing each piece of equipment.

As described above, it is possible to install an additional computer in a LAN environment, or to have a multi-coupler that can be applied by various connection methods that may additionally connect equipment such as a telephone or a security camera, or a hub and broadcasting equipment. Integrate the line construction for data communication network and the line construction for electronic equipment terminal through one local area network (LAN) with multiple lines by allowing the design of key phone main equipment and monitoring equipment as a single equipment. As a result, not only can the construction cost be reduced, but the facility can be expanded through the existing UTP cable without any additional work, thereby preventing the waste of resources, and the benefits of manpower reduction through integrated multi-network management can be obtained. Therefore, using this principle, despite the low technical difficulty, Impact of the non-reduction is anticipated to rent.
