Description

System for Providing High Speed Information and Communication Services in Apartment Houses {SYSTEM FOR PROVIDING HIGH SPEED INFORMATION COMMUNICATION IN A PUBLIC HOUSE}

The present invention relates to a system for providing ultra-high speed information and communication service to a multi-family house such as an apartment. Especially, high-speed information of a multi-family house that provides voice and data signals to different premises in a centralized communication room without modulating one signal into a single band. It relates to a communication service providing system.

The conventional network configuration for the high-speed information and communication services in a multi-family house includes an ASL (Asymmetric Digital Subscriber Line) and a LAN (Local Area Network) method that can be serviced only by existing telephone facilities. In recent years, however, new cable construction has been introduced in Korea, and optical cables have been introduced into intensive communication rooms in the premises that are equipped to provide network services in apartment complexes.

Hereinafter, with reference to the accompanying drawings will be described the network configuration in the centralized communication room. 1 is a block diagram showing a network configuration of a centralized premises communication room according to the prior art.

Referring to FIG. 1, the network configuration of the central office communication room integrates and receives data signals and voice (telephone) signals transmitted from an external network and then separates them again, and the separated voice signals are separated from the DSLAM. (Digital Subscriber Line Access Multiplexer, 120) and MDF (Main Distributed Frame, 130) is delivered to each generation 140, the separated data signal is received by the LAN system 150 to accommodate the necessary equipment for each generation (140) Is sent to the distribution. Alternatively, the voice and data signals separated and supplied by the optical station apparatus 100 may be merged by other modulation techniques and transmitted to each household 140 through the existing local telephone line 135.

The LAN method 150 includes a channel service unit (CSU) 151 for properly converting digital frames transmitted and received from each generation 140 to a wide area network, and a router connecting each generation 140 with an external network ( 152, switching hub 153, converter 154, and LAN rack 155.

The problem with such a conventional network configuration is that it is difficult to flexibly cope with the enhancement of the transmission band performance of the incoming external network (or public network) because the capacity of the optical station device as an integrated accommodation facility is limited to 155 Mbps. . That is, the current optical station equipment is designed to meet only the 155Mbps speed condition standard, so the ability to cope with network changes is poor. In particular, the optical station equipment is an expensive equipment, which is problematic in terms of continuous use because the utility company's utility value decreases.

Another problem of the network construction according to the prior art is that the rectifier and power supply must be installed for the component equipment mounted inside the integrated facility, and it is actually used because it has to be manufactured in an enlarged space standard in order to accommodate future expansion. Compared to the subscribing capacity, there is an inefficiency that occupies a lot of room space.

An object of the present invention is to solve such a problem of the prior art, by providing the voice signal and data signal to the premises communication room independently in different lines without merging process, the facility cost and bandwidth according to the expensive optical end station device It is to provide a system for providing high-speed information and communication service for apartment houses that can cope with future network performance improvement by excluding restrictions on increase.

In order to achieve the above object, the present invention is a high-speed information communication service system in a multi-family housing complex that receives voice signals and data signals from an external communication network through separate transmission lines, respectively, wherein the central office communication room is the A routing unit for routing the incoming data signal through a line and transmitting the data signal to each generation; a voice signal connection device for separating the voice signals of multiple generations of the multi-family housing complexes into one generation; And a subscriber line receiving module for separating the real-generation separated voice signal by subscriber generation, and a line splitting device for separating and transmitting the voice signal separated by the generation to the line of the subscriber generation.

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

2 is a block diagram illustrating a system for providing a high speed information communication service for a multi-family house according to the present invention.

As shown in FIG. 2, the high-speed information communication service providing system includes a national or other public network facility 200, a centralized premises communication room 300, and a switching module 400. The voice signal connection device 310, the subscriber channel accommodation module 320, the subscriber line concentrator 330, the line splitter 340, and the routing unit 350 are provided.

The national or other public network facility 200 modulates a voice signal and a data signal received through a public network (for example, a public switched telephone network (PSTN), a public switched data network (PSDN), a wireless network, etc.) into one band. It transmits to the centralized communication room 300 through different lines 201 and 202 without processing.

The voice signal input to the central office communication room 300 through the line 201 is a voice signal connection device having an optical multiplex transmission function for separate transmission to a real generation because multiple generations of voice signals are combined in one band. After being distributed by the subscriber generation group 310 again, it is transmitted to the subscriber channel accommodation module 320 and transmitted to each subscriber generation through the circuit division apparatus 340 which handles the last generation circuit acceptance. Here, the subscriber line concentrator 330 may be inserted between the subscriber channel accommodation module 320 and the line splitter 340 to be connected to accommodate the existing xDSL (xDigital Subscriber Line) service.

The data signal entering the central office communication room 300 through the line 202 is interfaced by the network interface device 351 of the routing unit 350 to allow access to the external network. Representative interfacing devices include routers.

As such, the direct routing and connection of data signals by the manganese interfacing device 351 is advantageous for accommodating high-speed data transmission lines such as Metro Ethernet.

The routed data signal band is distributed by the switching module 352 to the copper switching module 400 which is a LAN facility accommodated in each wing. The switching module 352 functions as a backbone switch that divides and distributes data signals for all generations of the apartment complex by the required band.

Here, the switching module 352 and the manganese interfacing device 351 may be configured as one device in which functions are integrated or may be connected as separate devices.

The LAN switching module 400, which is a LAN facility distributed in each building, may be partially accommodated or all accommodated in the centralized premises communication room 300 depending on the structure of the apartment complex.

As described above, the present invention introduces the data signal and the voice signal transmitted from the external communication network into the centralized communication room in separate states, and transmits the independent voice signal and the data signal to each generation, thereby providing It can effectively cope with the increase of external network performance by eliminating the facility cost and the restriction on the increase in bandwidth.

In addition, the present invention can omit a device such as an optical end station device and a CSU installed in a centralized communication room for band matching, thereby achieving efficiency in construction.
