Comprehensive cabling scheme for financial building

Information resources play an important role in the financial system. Given the specific nature of the financial system, a single form of residence network is difficult to meet demand. Depending on the nature of the work of different departments, there must be different forms of network to meet their different needs. Even in the same sector, the need for network forms may change at different times. There will be more problems if the department moves. Therefore, it is necessary to have a complete and flexible open integrated wiring to support these applications. First of all, the integrated wiring must have high reliability, in order to ensure the daily business of the financial system smoothly; second, the integrated wiring should have a high degree of flexibility, according to the specific requirements of the Department, in the distribution frame connected to different extension structure. At the same time, if the network form change can easily be changed into different topological forms.
　　
In recent years, with the implementation of the forward-looking infrastructure of the "information superhighway", we see that the dream of establishing high-quality remote data communication channels around the world has become a reality. In foreign countries, integrated Digital Services Network (ISDN) has developed into a fairly mature technology, and formed a communication standard. In the domestic, the major cities have also opened integrated Services Digital network. It can be foreseen that in the near future, information communication will enter an integrated service digital network ERA. Therefore, a financial building in the design, planning process, it should be considered that the information channel should be adapted to different network interconnection equipment, host, terminal and peripheral requirements to form a flexible topology structure, there is sufficient expansion capacity; externally, it can be connected to other buildings abroad through integrated Digital Services Network (ISDN) , and constitute a full range of information Exchange system. In other words, a financial building, that is, to adapt to the needs of the current information processing, but also fully take into account the future trend of housing technology.

The integrated wiring of the building consists of a working area and a horizontal subsystem. The five parts of the area, the main trunk subsystem and the equipment, have taken full account of the high reliability, the high speed transmission characteristic and the expansibility, and considered the possibility of connecting with other buildings into the construction trunk subsystem.
　　
The computer backbone network is suitable for the optical fiber Distributed Data Interface (FDDI) standard, the network bandwidth reaches above 500Mbps, can transmit the data and the image at high speed, can greatly improve the information transmission quality and the reliability, at the same time, also considered each floor workstation to enter the human FDDI network channel.
　　
Network backbone of the use of optical fiber, all connected with the computer network cabling hardware are 5 categories (100Mbps) products, that is, 5 types of information outlets, 5 types of fast jumper, 5-type twisted pair cable. This not only satisfies the present demand, but also lays the foundation for the multimedia application.
　　
The program controlled by the host House Unified management, each line is 4 pairs of twisted pair cable configuration, design bandwidth (Mbps), can meet the integrated service digital network requirements, thus laying the foundation for high-speed data transmission.
　　
Security monitoring system can transmit video surveillance signal and security sensor signal.
　　
Programme details
　　
Integrated wiring, we selected a flexible star topology structure, through the wiring racks on the jumper or network equipment constitute a different logical structure, not only for the needs of the program-controlled telephones, but also for computer network systems, security monitoring systems, as well as building control system requirements. The structure of the integrated wiring is divided into two star types: the main cadres are divided into level, level two. The Star Structure center of the backbone part is in the main room, radiate to each floor, transmits the medium as the fiber and the large logarithm twisted pair cable; the star Structure center of the horizontal part is in each floor wiring, from the wiring frame leads the horizontal twisted pair cable to each information point. This will form a two-story star-type two-point management mode, to achieve the integrated wiring in the connection, configuration flexibility.
The following five parts of the entire wiring are described individually.
　　
1. Work area
　　
Work area consists of various office areas, according to the specific needs of a hole to four hole information sockets, 5 types of information outlets can support 100Mbps and below high-speed data communication, image communication and voice chant letter.
　　
Each information socket, can support a Low-speed data terminal or two telephone (terminal) through 400K sockets, so that the integrated wiring has a strong scalability.
　　
　　　
　　
2. Horizontal Subsystem
　　
According to the specific civil structure characteristics of the bank's comprehensive office building, the position of the weak electricity, the position of the information outlet, and taking into account the end-to-end margin, the average length of the horizontal subsystem is 45 meters, and the data and video transmission uses 5 kinds of 4 pairs of twisted pair cables, which can support the 10Mbps 3 and 5 types of twisted-pair cables have strong anti-interference, high equipment redundancy, so that the integrated wiring has a high reliability.
　　
3. Management
　　
According to the statistics of the information points of each layer, a total of 5 floors in the building of the wiring room (five floors do not have separate floor wiring), the number and information between the wiring points as shown in the table below.
　　
Information Point Distribution
