Description

Digital Terminal Access MultiHUB System

The present invention relates to a local area network (LAN), a private exchange system, a broadcasting equipment, a sensor detection system, and the like, and in particular, performs a video transmission and a stereo audio transmission at the same time, with a built-in data exchange on a single UTP cable. In addition, it is possible to implement input / output transmission such as telephone communication network and sensor detection alarm network at the same time as data exchange is basically built in one UTP cable, or all of these functions can be integrated in one multi hub system. The present invention relates to a digital terminal access multi-hub multiplexing system integrating a hub and communication using a communication network (LAN).

In general, a local area network (LAN) exchanges data according to requests between computers through a switching hub, and an unshielded twisted pair cable (UTP cable) terminated by RJ-45 is used.

In addition, the private telephone system (Keyphone System) switches the call path between the station and the station subscribers or between the station subscribers and the trunk line subscribers according to the needs of the station subscriber, the UTP cable is terminated by RJ-11.

In general, a sensor detection system uses a cable of a corresponding standard, and a broadcast system for transmitting video and audio generally uses a cable terminated with an RCA plug.

As described above, the conventional broadcasting equipment system performs a multimedia operation by connecting a video and audio transmission signal between a broadcasting room and an internal terminal with a shield line. In addition, the conventional private switching system performs a telephone call by connecting a private exchanger and a telephone of an extension subscriber with a telephone line. In addition, the personal computer of the station subscriber is connected to the station subscriber's telephone separately by a LAN cable to perform data communication. That is, the conventional broadcasting system is interconnected by a shield line, and the private switching system has a need to separately configure a LAN cable network for data communication separately from a network for a telephone call.

In addition, in recent years, as office electronics is becoming more and more advanced, the demand for office automation equipment such as digital copiers, printers, scanners, and facsimile has increased so that each office automation equipment has its own functions. In order to achieve high performance, each office automation device used independently is being developed as a single unit.

For example, a number of multi-function terminals made by weaving existing terminal devices such as facsimile machines, scanners, printers, and digital copiers into one unit have been released. In general, such multi-function terminals have a host computer interface (Host), which is a function that works with a host computer. By providing a computer interface function, a product that performs a compound document output function while providing economic saving and installation space for the user is being produced and provided.

With the trend of office automation, and with the rapid development of the information and communication industries, the implementation of integrated office automation of general establishments and administrative agencies, etc., has led to the establishment of local area networks (LANs). Informatization plays a leading role in increasing the integration of office automation environment, such as computer communication is common by installing one person one and one person one phone.However, due to the expansion of additional cables, It is the present situation that is becoming complicated and diverse.

However, the construction of the telecommunication network line represented by such a local area network (hereinafter, abbreviated as 'data line construction work') and the construction of the telecommunication terminal line represented by telephone (telephone, facsimile, video camera, sound equipment) It is well known that construction of connecting various sensors, etc., which is collectively referred to as 'multi-line construction' (hereinafter, abbreviated as 'multi-line construction work') has a different line system and wiring installation system. .

As a result, the data line construction work and the multi-line construction work are separately carried out, resulting in the following problems.

(1) As separate wirings for data lines and multi-line are installed in duplicate, there is a problem that the usable office floor area is reduced and the working environment is poor due to the complicated wiring system.

(2) In the case of reorganization, relocation of office furniture, etc., when the personal computer, key phone, and speaker used by an individual are to be moved to another place, the work of dismantling or dismantling the data line and multi-line must be done separately. In addition, since the construction to install it is also made separately, due to the duplication of work, there is a closure that the work efficiency is lowered and the cost is increased.

(3) Multi-line management and data line management must be performed in duplicate to manage and maintain, resulting in additional burdens and unnecessary effort in securing manpower.

(4) If the data line and the multi-line are connected over a large area, and the number of connection holdings is large, the management and maintenance of each line becomes complicated and difficult, such as having to provide a separate line layout drawing. have.

(5) In addition, a track construction that can recognize this by additionally installing surveillance cameras or attaching various sensors (fire sensor, crime prevention sensor, temperature sensor, etc.) in a service area constructed in a LAN environment. There is also an additional burden of building new tracks.

(6) If each line is complicated and variously installed various cables are congested, the speed of menopausal change that leads to poor quality of the line is accelerated, and due to interference caused by induced current between lines, There is a high possibility of serious problems such as a significant decrease in data transmission quality.

Accordingly, the present invention has been made in view of the above problems, and by providing an additional device of a multi terminal, such as a telephone or a sensor, in a network interface facility in a LAN environment, through one UTP cable having a plurality of twisted lines By integrating the construction work on the data communication network and the construction work on the multi network into one UTP cable, the construction cost can be reduced and the office environment can be easily improved by the integration of various wirings. In addition, it aims to provide a digital terminal access multi-hub multiplexing system integrating a hub and communication using a local area network (LAN) to obtain the advantages of manpower saving through integrated network management.

In order to utilize the present invention, a multi-coupler (application number: 20-2001-0028085, hereinafter referred to as a multi-coupler) previously applied must be used in parallel. When the system is configured as shown in FIG. The technical problem is to provide a digital terminal access multi-hub multiplexing system that integrates a hub and communication using a local area network (LAN) that can facilitate or facilitate the transmission of video data.

In order to achieve the above object, the present invention transmits the media signal and the data signal transmitted from the multi hub to the terminal of the subscriber station through a single UTP cable incorporating the present invention, and transmits the data signal and the media signal from the multicoupler. After separating each of them, and connecting them to the corresponding terminal, the subscriber's media equipment and the subscriber's personal computer can be used in parallel with one existing UTP cable, and the subscriber's personal When the digital data signal transmitted from the computer and the media signal of the station subscriber are integrated into the multi-coupler into one, and the integrated signal is transmitted to the multi hub through a single UTP cable, Not only can you unify dramatically In addition, since one existing UTP cable can be used together with an existing computer and one or two additional terminals without additional transmission cables, simplicity, convenience, and economics of the work environment can be used. It is characterized by being able to pursue at the same time.
