According to the bidding requirements: the total number of building information points to 500 points, the use of more than 5 types of cabling system, part of the use of optical cable to the table. As the basis of information transmission of the integrated wiring system, the focus of its design is: to center room as the core, the office building of the floor with cable and large log cable and the center of the room into an organic whole, so that the system has a stable and reliable, high-speed rate, standard, open, flexible, applicable, scalable performance characteristics, In order to meet the new office buildings in different forms of application requirements.

2.2 Application Requirements Analysis

As the basis of information transmission of the integrated wiring system, must support the current and future voice, data, video conferencing, control and other high-speed transmission of information requirements, for news collection, editing, transmission, publishing and other series of work towards the information, networking lay the foundation.

Therefore, the comprehensive cabling system construction of ********-office building should be considered as a whole. To build an efficient information network, you must have a complete set of high-quality integrated wiring system! For the needs of users and the nature of this wiring project, we recommend the use of the United States Avaya Systimax SCS structured wiring system. This is a set of broadband integrated digital services network requirements and special design of high-quality wiring system, in line with the Ministry of Telecommunications promulgated the standard "Building communication structured wiring System specification", once pushed into the market immediately received a wide range of global response. Avaya Company's Systimax. SCS is a end-to-end full set of cabling solutions, all products are by the Avaya company exclusive research and development, production, and no one product is produced by other manufacturers OEM, which fully guarantee the integrity of the product performance and excellent matching.
