Integrated wiring system is the one for the transmission of voice, data, video and other information system standards for structured cabling. Is a building or buildings within the transmission network, which allows voice and data communications equipment, switching equipment and other information management system linked to each other. Integrated wiring system uses a structured cabling approach the building of computer systems, telephone systems, intercom, surveillance systems into a unified structure, the same material, the unified management of physical, high-quality unshielded twisted-pair replace the traditional coaxial cable and special cables, completely resolve the high-speed data transmission, line, and intersymbol interference problems, such as electromagnetic radiation.

The past is the routing method of routing a wide range of facilities design and construction were carried out, such as telephone systems, fire, security alarm systems, energy management system is independent. A higher degree of automation of the building, all kinds of lines such as Ma, is not only difficult to manage, wiring costs are high, but less than functional, not meet the needs of the development of the situation. PDS is the lack of response to these standardized measures taken to achieve a uniform material, unified design, unified routing, unified installation of construction, structural clarity, ease of centralized management and maintenance.

Generic Cabling System

PDS, Premises Distribution System: is the distribution of computer and communication system design, which is that it can meet a variety of different computers and communication requirements. It includes:
1) analog and digital voice systems;
2) high-speed and low-speed data system;
3) fax machines, graphics terminals, plotters, such as the need to transfer the image data
4) video conferencing and security surveillance system video signal;
5) 28 VHF broadband transmission of video signals;
6) integrated wiring for the safety of buildings, alarm and air conditioning control system for sensor signals.
PDS to meet between the buildings and structures within all computers, communications and building automation equipment integrated wiring system, wiring needs. As the PDS is a set of integrated systems, integrated wiring can therefore use the same cable with the wiring terminal board, and the same modular plug and jack for voice and data transmission, can not worry about the compatibility of equipment issues.

PDS use of modular design, so the most easy to expand and re-wiring on the portfolio. The use of star-shaped topology, as well as with telecommunications EIA/TIA-568 wiring followed the same way as buildings. Because in the star-shaped structure, the workstation is created by the central node outward, and each line has nothing to do with the other lines. As a result, changes and re-arrangement of equipment, only affect the related line that, while no effect on all other lines. In addition the structure of the fault system will make it very easy to analyze. Once the system failure, can quickly find the point of failure and be excluded completely.

PDS is a subsystem of the six independent components by using star-shaped structure, a subsystem will enable independent access to PDS system.
     6 sub-systems as follows:
1) Work Location: It is by the information terminal equipment connected to the outlet of the equipment between the composition, including information outlet, outlet box (or panel), connecting cord, adapter and so on.
2) Horizontal: Its function is to extend the trunk line system to the user workspace. Level system is arranged on the same floor in a termination socket in the information, the other end of the layer with the jumper between the shelves. Subsystem level are mainly non-four pairs of unshielded twisted pair, it supports most modern communication equipment, broadband transmission requirements in some time, to be used in "fiber to the desktop" option. When the level of a very large area, in this interval that there may be one or more satellite connection, the horizontal line in addition to receiving devices other than client, but also via satellite connection, the received information to the exit terminal.
3) Backbone: usually it is from the main devices (such as computer rooms, program-controlled switchboard room) to all levels of management between. It is great for a number of feeder cables or fiber optic cable, both ends of the respective inter-access equipment and management in the jumper between the shelves.
4) Equipment: It is the cable between the equipment, aircraft and related jumper for hardware support, mine electrical protection devices, etc.. Ideally, the setting is the computer room, switch room and other equipment design in the same floor, so not only manageable, but also to save the investment. Of course, under the specific circumstances of the building design among multiple devices.
5) Administration: It is the level of subsystems and subsystem Link bridge and at the same time as the network layer to provide the same conditions. Including twisted pair jumper frame, jumper (with quick and easy-fit jumper jumper of points). In the need for fiber-optic cabling system, it should have the jumper fiber and fiber-optic jumper aircraft. When the location of terminal equipment or local area network structure changes, as long as the way to change the jumper can be resolved without the need for rewiring.
6) Campus: It is more than one data communications signal building's wiring system to connect together. It can be installed overhead or underground cables along the pipeline (or direct burial) of copper and fiber optic cable laying, and cable to prevent the surge voltage to enter the building electrical protection device.

The characteristics of an integrated cabling system

Integrated wiring system and compared to traditional cabling system, there are many advantages, the main performance in the following areas:
1) the so-called compatibility means the compatibility of their equipment or procedures can be used in a variety of system features. Integrated wiring system will be voice signals, data signals with the monitoring equipment, the wiring of the image signal through a unified planning and design, using the same transmission medium, and information outlets, cross-connect equipment, adapters and so on, the nature of these different signal integrated to a standard set of cabling systems. This compared with traditional cabling system can save a lot of material, time and space. When in use, the user can define a work area do not have information specific socket applications, only some kind of terminal equipment to access the information outlet, and then in the management and equipment between the cross-linked between the device and do the operation of the jumper, The terminal equipment will be access to your system.

2) open the way traditional routing, the user has selected a device, it is selected with suitable wiring methods and transmission medium. If the replacement of another equipment, the cabling system that will be replaced. So a lot of trouble on the increase and investment. As a result of integrated wiring system, open architecture, in line with the prevalence of a wide range of international standards, it is almost all the well-known vendors are open, such as: IBM, DEC, SUN computer equipment, AT & T, NT, NEC, etc. switch equipment. And almost all of the communication protocol is open, such as EIA-232-D, RS-422, RS-423, ETHERNET, TOKENRING, FDDI, CDDE, ISDN, ATM and so on.

3) the flexibility of integrated wiring system, as a result of the use of all information systems are the same transmission medium, physical star topology, all channels of information are common. Information of each channel can support telephone, fax, multi-user terminal. 10Base-T and Token Ring workstations workstations (using Category 5 connectivity solutions to support 100Base-T and ATM, etc.) and the opening of all equipment changes are not required to change the system wiring, simply increase or decrease in the corresponding network equipment, as well as the necessary management to the jumper. In addition, the network system can also be flexible and diverse, even in the same room could be more user terminals, 10Base-T workstations, Token Ring workstations coexist, and organize information for the user to provide the necessary conditions.

4) the reliability of integrated wiring system uses a high-quality materials and combination of press-fit manner constitute a set of high standards of information access. All devices through UL, CSA and ISO certification, each information channel to be physical star topology, point-to-point termination, any of a line fault do not affect the operation of other lines, as well as lines of operation and maintenance and fault Maintenance provides a great convenience, is to ensure that reliable operation of the system. The system uses the same transmission medium, which can backup each other to improve the back-up redundancy.

5) The nature of integrated wiring system uses fiber-optic and twisted way mixed cloth, very reasonably constitute a complete cabling system. All wiring are the world's latest communications standards, and information channels are B-ISDN design standards, according to the eight core twisted-pair configuration, through the Category 5 twisted-pair, the maximum data rate of 155Mbps, for a particular user needs can be optical fiber Shop to your desktop (Fiber - to the Desk). Route 500M fiber optic cable can be designed for the bandwidth for the future development of a sufficient margin. Through the trunk channel at the same time multi-channel real-time transmission of multimedia information, while the physical star wiring for the future development of the network switched to lay a solid foundation.
