Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-hub multiplexing system and a voice and data integrated terminal distribution device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local area network (LAN), a private switching system, a broadcasting apparatus and a sensor detection system, and more particularly, , It is possible to simultaneously implement input / output of a telephone network and a sensor detection alarm network while incorporating data exchange to a single UTP cable, or to integrate all of the functions into one multi-hub system Access to digital terminal that integrates communication with hub using LAN

To a multi-hub multiplexing system.

In a local area network (LAN), data is exchanged according to the request of each computer through a switching hub, and an unshielded twisted pair cable (RTP) terminated by RJ-45 is used.

In addition, the private key exchange system (Keyphone System) switches between the extension subscribers and the extension subscribers or between the extension subscribers and the extension subscribers according to the demand of the extension subscriber, and UTP cable terminated by RJ-11 is used.

Generally, the sensor detection system uses the cable of the standard, and the broadcasting system that carries out the video and audio transmission uses a cable which is generally terminated by an RCA plug.

As described above, in the conventional broadcasting equipment system, video and audio transmission signals between a broadcasting room and an internal terminal are connected by a shield line to perform multimedia work. Also, in the conventional private switching system, a telephone exchange is performed by connecting a private branch exchange and a telephone of an extension subscriber through a telephone line. The personal computer of the extension subscriber is connected to a LAN cable separately from the telephone of the extension subscriber, and performs data communication. That is, the conventional broadcasting system is interconnected by a shield line, and the private switching system has to separately manage a LAN cable network for data communication separately from a network for telephone conversation.

In recent years, demand for office automation devices such as digital copiers, printers, scanners and facsimiles has surged on the basis of office automation, which is at the forefront of power generation, so that each office automation device has its own functions In addition, each office automation device that was used independently is being developed as an integrated type.

For example, many multifunctional terminals have been developed which are made by bundling together existing terminal devices such as a facsimile, a scanner, a printer, a digital copying machine, etc. In general, such a multifunctional terminal includes a host computer interface Computer Interface) function, it is possible to reduce the installation cost and save the user's money while simultaneously producing a composite document output function.

In addition to this office automation trend, it is becoming common that a LAN (Local Area Network) is constructed through the integration office automation of general offices and administrative agencies due to the rapid development of information industry and communication industry, One computer per person and one computer per phone are used to generalize the computer communication, and IT is playing a leading role in enhancing the integration of the office automation environment. However, due to the addition of additional cables, It is the present situation that it is complicatedly diversified.

However, in the case of construction (telephone, facsimile, video camera, audio equipment, etc.) for a communication network line represented by such a local area network (hereinafter, abbreviated as "data line installation work" , Various sensors and the like, which are collectively referred to as "multi-line installation work"), it is well known that they have different line systems and wiring installation systems .

As a result, the following problems arise due to the separate implementation of the data line construction and the multi-line construction.

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

(2) In case of reorganization of office or rearrangement of office furniture, if the personal computer and key telephone and speaker used by the individual should be transferred to another place, the operation of demolishing or disassembling the data line and multi-line should be separately performed In addition, there is a problem that the work efficiency is lowered and the cost is increased due to the double work because the work for constructing this is also separately performed.

(3) Since the multi-line management and data line management tasks must be managed and maintained in duplicate, unnecessary effort and cost are incurred to secure the manpower to cope with the same.

(4) When a data line and a multi-line are connected over a wide area, and the number of connections is large, it is necessary to provide each line layout diagram, which complicates and makes maintenance difficult for each line have.

(5) In addition to the service area built in the LAN environment, a surveillance camera can be additionally provided or a line construction can be additionally carried out by attaching various sensors (fire sensor, security sensor, temperature sensor, etc.) When new

There is also an additional burden of building a drift line.

 (6) When each line is complex and various cables installed by sequential addition are congested,

The speed of ganglion change which becomes bad becomes accelerated, and there arises a serious problem that the quality of communication and data transmission is remarkably deteriorated due to the interference phenomenon caused by the induced current between the lines.
