An internal broadcasting network means a facility installed in the city so that a user can receive a broadcasting service and a communication service. The broadcasting communication network is divided into a broadcasting receiving facility and an intra-site communication line facility. Broadcast joint reception facilities consist of antennas and line facilities for jointly watching terrestrial broadcasts, co-viewing antenna and line facilities for satellite broadcasting, FM radio reception facilities, coaxial cable, amplifier and splitter for cable broadcasting reception. The communication line facility for data communication is composed of facilities such as optical fiber, UTP cable and L2 / L3 switch for communication between inside and outside of the city.

The conventional indoor communication network includes a separate room provided in a management room of a building or a broadcasting room installed in an intensive communication room (MDF room) And MAIN DISTROUBLEMENT FRAMES (MDFs), which are connected to an external line such as telephone, wired broadcasting, data communication service provider, and an internal communication communication facility through communication equipment. The intensive communication room is equipped with a data main distribution board (MDF), which includes telecommunication equipment such as a telephone main circuit board (MDF) to which a telephone line (trunk line) is connected, and an L2 / L3 switch for data communication, A broadcasting head end for reception of a public announcement such as a terrestrial broadcast and a satellite broadcast, and broadcast head end equipment for a cable broadcast are installed. From the centralized communication room to the household terminal box, the intra-city communication network is constructed from the main distribution board through the INTERMEDIATE DISTRIBUTION FRAME, the IDF or the main / intermediate terminal box to each household terminal box for telephone, data communication and broadcasting. The wiring for public hearing and cable broadcasting is installed only by coaxial cable, the optical cable is installed up to the copper / intermediate terminal box, and the coaxial cable is installed thereafter. If the coaxial cable is installed, The difficulty in designing and constructing for reception becomes high. In addition, due to the loss ratio of the frequency band of the signal outputted by the attenuation characteristic of the coaxial cable, the output loss due to the wide band of 54 ~ 2150MHz frequency, image quality failure due to various noise, For data communication, the optical cable is generally installed to the intermediate wiring board, and the UTP cable, the optical cable or the optical and UTP cable are mixedly wired in the subsequent section.
