[guidance] comprehensive wiring is the central nervous system of intelligent building. It uses high quality standard cable and related connection hardware to make up a standard, flexible and open information transmission channel in the building.
The world has entered the information age. With the rapid development of information processing system, the requirements for the rapid, convenient, safe and stable reliability of information transmission are becoming higher and higher. Intelligent building is the product of the information age.
The integrated wiring is the central nervous system of the intelligent building. It uses high quality standard cable and related connection hardware to make up a standard, flexible and open information transmission channel in the building. It can not only transmit voice, data and image inside the building, but also connect to the communication network outside the building. The network network device, different host, terminal, PC and the external equipment to adapt to, can form a flexible topology, sufficient system capacity expansion, through foreign and national public data network (CHINAPAC), integrated services digital network (ISDN) is connected with the domestic and foreign news agencies, information center, information to access the full range of multi channel system.
The integrated wiring system in the design of the park should be equipped with the following features:
Transparency: it can support all current standards, such as telephone communications, data transmission and video applications (IEEE, ITU-T, ANSI, etc.).
Adaptability: there is room for future technology development, such as office automation and satellite high speed network applications.
Flexibility: because the generic cabling system adopts a unified wiring network, that is, a unified transmission medium (twisted pair and optical fiber) to support all types of communication systems, so that users can easily change the location of terminal devices or install new terminal devices.
Summary
The park used to meet the five standard ISO/IEC11801 ultra Taiwan Canbo integrated wiring system as the transmission media voice, data and image communication system in the building, using standard network construction and INTERNET access, data / voice / video "triple play application development mode"; the network operating system and platform coexistence mode considering that, the modern office environment of communication automation (CA), office automation (OA) information transmission system needs a high degree of flexibility and reliability and comprehensive wiring, and easy development and convenient maintenance and management and future expansion.

(3) meet the requirements of computer network system such as office automation of building.
(4) the comprehensive wiring system adopts the full modular structure to facilitate the expansion of the system, and it has great flexibility. When the system changes or the equipment shifts, there is no need to rewire, only the corresponding line jumpers can be jumper.
(5) the wiring system of this project is a tree shaped structure to support the application of various networks in the future and in the future. Interconnect with different network devices through a jumper line. Networks of various logical topological structures can be implemented.
2. design goal
The design of this cabling system aims at building a comprehensive cabling system with openness, flexibility, practicability, expansibility, economy and safety, which integrates voice, communication, data and communication, and achieves the following objectives.
Standardized network systems, various design specifications, technical indicators and products are all in line with international and industrial standards, and can provide multiple brand product support capabilities.
The expansion of the system is combined with the trend of technology development, and the implementation of the wiring scheme is selected, considering the needs at this stage, and it has enough expansion capacity for future development.
Information exchange resources sharing, interconnection through the network, the sharing of resources and the connection with the external network.
3. system characteristics
The system of each floor in the park should be comprehensive, and the user should not rewire when reconnecting or arranging the terminal of the workstation. The network system design must meet the networking requirements of the workstation and meet the requirements of the software operation. The wiring system must be integrated with the network system.
Flexibility: any information point can connect different types of devices, such as computers, printers, terminals or telephones, fax machines and various sensors, image monitoring devices, etc.
Modularization: all connectors should be the standard parts of the block type, convenient to use management and expansion.
Extensibility: taking full account of development and change. When environment change and network equipment upgrade, only need to have flexible jumpers on the distribution rack without rewiring.
Economy: to reduce the cost as much as possible and have good return on investment.
