1. Definition The structured integrated wiring system is a telecommunications wiring system that can support any user-selected voice, data, graphic and image applications. The system should be able to support the transmission of various information such as voice, graphics, images, data multimedia, security monitoring, sensing, etc., support various transmission carriers such as UTP, optical fiber, STP, coaxial cable, etc., and support the application of multiple users and types of products. Support high-speed network applications. 2. Features Structured wiring system has the following characteristics: 1) Practicability: It can support a variety of data communications, multimedia technologies and information management systems, etc., and can adapt to the development of modern and future technologies; 2) Flexibility: Any information point can be connected to different types of devices, such as microcomputers, printers, terminals, servers, monitors, etc .; 3) Openness: able to support any network product of any manufacturer and any network structure, such as bus, star, ring, etc .; 4) Modularity: All connectors are standard building blocks, which are convenient for use, management and expansion; 5) Scalability: The structured wiring system after implementation is expandable, so that when there is greater demand in the future, it is easy to install the equipment; 6) Economical: One-time investment, long-term benefit, low maintenance cost, minimize the overall investment. 3. Composition of the wiring system According to the general division, the structured wiring system includes six subsystems: work area subsystem, horizontal branch trunk subsystem, management subsystem, vertical backbone subsystem, equipment subsystem and building cluster backbone subsystem. 1) The main subsystem of the building complex Provide a connection point between the external building and the wiring in the building. The EIA / TIA569 standard stipulates the physical specifications of the network interface and realizes the connection between building groups. 2) Equipment subsystem The EIA / TIA569 standard specifies equipment wiring between equipment. It is the most important management area of ​​the wiring system, and all the floor information is transmitted here by cable or fiber optic cable. Usually, this system is installed in the host room of computer system, network system and program control computer system. 3) Vertical backbone subsystem It connects the communication room, equipment room and entrance equipment, including backbone cables, intermediate switching and main handover, mechanical terminals, and patch cords or plugs for backbone to backbone exchange. The backbone wiring should adopt a star topology, and the grounding should meet the requirements specified in EIA / TIA607. 4) Management subsystem This section places telecommunications wiring system equipment, including mechanical terminals and 1 or switching of horizontal and backbone wiring systems. 5) Horizontal branch trunk subsystem Connect the management subsystem to the work area, including horizontal wiring, information sockets, cable termination and switching. The specified topology is a star topology. There are three kinds of media for horizontal wiring (100 ohm UTP cable, 150 ohm STP cable and 62.5 / 125 micron optical cable), the farthest extension distance is 90 meters, in addition to the 90-meter horizontal cable, the work area is connected to the management subsystem The total length of the patch cord and jumper cable can reach 10 meters. 6) Workspace subsystem The work area extends from the information socket to the station equipment. Work area wiring requirements are relatively simple, which makes it easy to move, add, and change equipment.
A
BBQ grill is a cooking appliance used for outdoor cooking, specifically
for grilling food over an open flame or hot coals. It typically
consists of a metal grate or griddle that is placed over a heat source,
such as charcoal or propane gas. The grill can be used to cook a variety
of foods, including meats, vegetables, and seafood. BBQ grills come in
different sizes and styles, including portable models for camping or
tailgating, and larger models for backyard entertaining. Some BBQ grills
also include additional features such as side burners, rotisserie
attachments, and temperature gauges.
