3 System design
3.0.1 The integrated wiring system (GCS) should be an open star topology and should be able to support the needs of multimedia services such as telephone, data, graphics, and images.
3.0.2 The integrated wiring system should be designed according to the following six parts: 1 Work area;
2 Wiring subsystem;
3 Trunk subsystem;
4 Equipment room;
5 Management;
6 Building complex subsystem.
3.0.3. The engineering design of buildings and building complexes should select an appropriately configured integrated wiring system based on actual needs. When the network usage requirements are not yet clear, it is advisable to configure according to the following provisions: 1. Minimum configuration: Applicable to occasions with lower configuration standards in the integrated wiring system, using copper core twisted pair cables for networking. 1) Each work area has 1 information socket: 2) The distribution cable for each information socket is a 4-pair twisted pair cable: 3) For the configuration of trunk cables, for computer networks, 24 information sockets should be equipped with 2 pairs of twisted pairs, or each hub (HUB) or hub group (HUB group) should be equipped with 4 pairs of twisted pairs: For telephones, at least 1 pair of twisted pairs should be equipped for each information socket. 2 Basic configuration: Applicable to occasions with medium configuration standards in the integrated wiring system, using copper core twisted pair cables for networking 1) Each work area consists of 2 or more information sockets: 2) The distribution cable for each information socket is a 4-pair twisted pair cable 3) For the configuration of trunk cables, it is advisable to equip 24 information sockets with 2 pairs of twisted pairs for computer networks, or 4 pairs of twisted pairs for each hub (HUB) or hub group (HUB group): At least 1 pair of twisted pairs for each information socket for telephones. 3 Comprehensive configuration: Applicable to occasions with higher configuration standards in the integrated wiring system, using optical cables and copper core twisted pair cables for mixed networking. 1) The basic configuration of information sockets is used as the basic configuration; 2) Configuration of vertical trunks: Every 48 information sockets should be equipped with 2-core optical fibers, which are suitable for computer networks; for telephones or some computer networks, twisted pair cables should be selected, and vertical trunk cables should be configured according to 25% of the wire pairs required for information sockets, or configured according to user requirements, and appropriate spare capacity should be considered:
3) When there are fewer information sockets on a floor, within the specified length, several floors can share HUBs and calculate the number of optical fiber cores together. The number of optical fiber cores calculated for each floor should also be selected according to the nominal capacity of the optical cable and actual needs. 4) If a user requires fiber to the desktop (FTTD), the optical cable can be directly connected with or without FD. From BD to the desktop, the above-mentioned number of optical fiber cores does not include the application of FTTD;
5) In principle, there are no vertical trunk cables between floors, but some connectors can be properly reserved in the FD of each floor, and suitable cables can be temporarily laid when necessary.
4 The selection of wiring equipment handover hardware should comply with the following regulations: 1) For wiring equipment used for telephone, IDC card-type modules should be used: 2) For wiring equipment used for computer networks, RI45 or IDC plug-in modules should be used. 3.0.4 The integrated wiring system should be able to meet the hierarchical requirements of the supported telephone, data, graphics, images and other multimedia services, and should use cables and connection hardware equipment of corresponding grades. 3.0.5 The classification and transmission distance limit of the integrated wiring system shall comply with the provisions listed in Table 3.0.5; Table 3.0.5 System classification and transmission distance limit Twisted pair cable transmission distance (m) System maximum transmission frequency 1002 Classification 100KHz 2000 100MHz Optical cable transmission distance Application examples X.21/V.11 N-ISDN CSMA/CD 1BASE 5 CSMA/CD 10BASE-T Token Ring 4Mbit/s Token Ring 16Mbit/s Token Ring Ring16Mbit/s
