Traditional Wiring Less than the traditional wiring mainly: different application systems (telephone, computer system, LAN, building automation system, etc.) wiring separate, different devices using different transmission cable form their own network and the connection cable sockets, modules and patch panels of the structure and production standards are different each other reach common purpose, with different construction periods, resulting in the formation of the great diversity of the cabling system is difficult to exchange General . This traditional approach because there is no uniform layout design, construction, use and management are not easy; when in the workplace need to re- Planning And equipment need to be replaced, Mobile Or increase, only to re-laying of cables, installation of plugs, sockets, and the need to interrupt office, apparently cabling work is very time-consuming, costly, inefficient.
Therefore, the traditional layout is not conducive to the utilization and management of cabling systems, limiting the application of the system change and expansion and upgrading of network size. Traditional Integrated wiring A bus topology, and cabling is star topology, each location in the room have enough ports available, and each room has cable set aside to expand space for large, centralized control by the unified management.
Cabling Integrated cabling system is a set of Building Material within or between buildings for the computer, communications facilities and Monitor Systems, information transmission channel pre-set. It voice, data, images, and other equipment connected to each other, while the device can communicate with external data networks. Integrated wiring system to meet the Integrated Services Digital Network (ISDN) needs developed a specially designed wiring, it is intelligent buildings and intelligent buildings in the information infrastructure to provide a multi-vendor products compatible, modular expansion, renewal and the possibility of restructuring the system flexible. Both for the user to create a modern information system environment, strengthen the control and management, but also for the users to reduce the cost of protecting Investment . Integrated wiring systems have become an important part of modern architecture. Cabling system applications of high-quality standard materials, non-shielded twisted pair and optical fiber transmission medium, using combination of crimping method, unified planning and design to form a complete and open wiring systems. The system will be voice, data, video signal routing and building security alarm, monitoring and management signals integrated in a standard wiring cabling system. On the wall or floor to set a standard socket, which socket adapter with a variety of computers, communications equipment and building Automation Connected devices. Cabling hardware Package Including the transmission medium (unshielded twisted pair, a large log Cable And Cable Etc.), patch panels, standard information outlet, adapter, photoelectric conversion devices, system protection equipment. Difference Traditional cabling is a bus topology, which is a star cabling topology, various locations in the room have enough ports available, and each room has a reserve cable, expansion in a large space, centralized control by the unified management. Fact, the structure cabling system is required to connect the device with the current position-independent, in the traditional wiring systems, equipment installation where the transmission medium where we should lay.
Structured cabling system is the first by the building structure, building all the possible locations for equipment are pre-announced the line and then connect the device according to the actual situation, by adjusting the internal jumper device, all devices connected up. The same line interface can connect different communication devices such as telephones, terminals or microcomputers, or even a workstation or host. Integrated wiring, you can make telephone points and data points used interchangeably, so construction can be applied when all arranged on the point and place, according to the situation in the future decide to use the application. Cabling is also pursuing the next level, in the building all the weak systems share the same transmission medium, which is great for the whole weak system to provide common integrated delivery platform. However, from the present situation is not to say that the application of relevant technology, but the cost is justified, it may take some time to develop.
