1 A brief introduction to the TIA-606-B Standard ANSI/TIA-606-B is a general telecommunications infrastructure management standard, which was promulgated in June 2012. This new standard is compatible with the previous ANSI/TIA-606mura standard. Appendix 1 is compatible with the international standard TR14763-2-1. The updated standard defines four levels of in-building or inter-building management according to the complexity of the managed infrastructure, and most importantly, the standard puts forward the requirements of an intelligent infrastructure management system. Usually, the management of network wiring affects the reliability of network operation, and the network interruption caused by any wiring or equipment failure will cause great economic losses. The update of ANSI/TIA-606-B telecom technical facilities management standards provides guiding principles for improving the efficiency of network management and maintenance. The early TIA-606-A standard only dealt with ordinary building wiring management, but did not mention and consider the management requirements of data center cabling design and installation. On the other hand, TIA-942-A mainly deals with the overall data center infrastructure design standards, and rarely talks about cabling management. The later updated TIA-606-An Appendix 1 was published in 2008, which brings data center cabling design and management together. TIA-606-B takes into account the requirements of TIA-606-An and appendix for data center cabling management and ISO/IEC TR14763-2-1. There is no denying that label management is one of the key factors for effective and professional installation and maintenance. The TIA-606-B standard continues to expand and position how to identify key information management systems (ITS) for underlying components. In addition, due to the integration of the standard ISO/IEC TR14763-2-1, the updated TIA-606-B has wider applicability. The new standard increases the investment value of owners by implementing convenient infrastructure management and reducing labor costs, thus prolonging the economic life of the system to provide effective services to users. 2 TIA-606-B management element model the following figure clearly describes the elements contained in a telecom infrastructure management system of TIA-606-B: 1. Path and wiring of wiring subsystem 1 (horizontal subsystem) 2. Path and wiring of cabling subsystems 2 and 3 (vertical backbone system) 3. Telecom grounding 4. Space (e.g. entrance facilities, telecommunications rooms, equipment rooms) 5. Fire prevention device

Figure 1: typical telecom infrastructure management element model 3 TIA-606-B changes relative to TIA-606-A 1. The marking scheme in Appendix 1 of TIA-606-An is adopted for cabinets, racks, wiring racks, telecommunications rooms and equipment rooms. These marking schemes are used to locate external telecommunications rooms and equipment rooms. two。 A new identifier format is defined for wiring subsystem 1, wiring subsystem 2 and 3, and campus backbone cables. However, the old identifier format that already exists is allowed to continue to be used. Note: in order to apply to all buildings, the term is selected from the TIA-568-C standard. Cabling subsystem 1 is usually defined as a horizontal link. Cabling subsystem 2 and cabling subsystem 3 are defined as (vertical backbone). Campus cabling has its own backbone system, which is different from the conventional 2-layer backbone cabling subsystem 2 and cabling subsystem 3. The standard allows one-layer cross-connection in wiring subsystem 1 and two-layer cross-connection in wiring subsystems 2 and 3. This provision makes the standard more general-purpose not only for data centers, but also for commercial, residential, industrial and medical buildings. 3. New markers are developed for telecommunications interfaces, equipment interfaces, fusion points, rendezvous points and outdoor communication spaces (maintenance holes, bases, manual controls, etc.). 4. It extends the management of communication and wiring system in the building. 5. Management cabling subsystems 2 and 3 are based on the corresponding ports rather than copper cable pairs and separate optical fibers. 6. Add ground connection system management, not just TMGB and TGB. 7. Allow existing label formats to avoid creating new tags for each element of the existing label system. 8. It provides a reference for intelligent infrastructure management system. 9. This standard has two label system formats, one is compatible with TIA-606-A, the other is based on TIA-606-An and compatible with ISO/TEC TR 14763-2-1. The label format that must be used in the newly designed telecommunications infrastructure is compatible with ISO/TEC TR 14763-2-1. 4 the level of management is divided according to the scale and complexity of telecommunications infrastructure construction, especially the number of telecommunications space (TS), such as equipment room (ER), telecommunications room (TR), access provider space, telecommunications service provider space, and access space. When upgrading between different levels, so that management is modular and compatible when different infrastructure parts are implemented in different periods. Management of accompanying text records, now through a variety of computer system software to achieve management functions. In the actual telecommunications infrastructure construction and use process, telecommunications equipment will have the need to upgrade and replace products. For example, a commercial building that can be used by many enterprises at the same time may have a useful life of more than 50 years. But for many enterprises, it is inevitable that some enterprises will move in and out, and then there will be an increase or change of equipment. The significance of label management is that after the cable is placed, the application may change frequently. Effective identification management provides great convenience for the effective management and flexible use of the wiring system, and for the maintenance and scheduling of the system. This standard not only establishes the principle of management, but also increases the use value of telecom infrastructure system and improves the return on investment by reducing labor cost, reducing system error probability, prolonging the economic life of the system and so on. The management is divided into four levels, from level 1 to level 4, the management content increases gradually, the management requirements of level 1 are less, and level 4 has the highest and strictest management requirements because of the high complexity of the whole telecommunications infrastructure. The following briefly lists the elements that need to be noted for each level of management requirements: level 1 telecommunications infrastructure served by a single device. There are only equipment rooms, and there are no separate telecommunications rooms and vertical wiring subsystems. Level 1 can be based on the management of record books or spreadsheet software. For level 1 management, the following components must be clearly marked: 1. Equipment room 2. Cabinet, rack 3. Distribution frame and distribution terminal 4. Distribution frame port and distribution terminal location 5. Cabling 6. 6 in the middle of cabinets, racks and distribution frames. Link 7 of wiring subsystem 1. Telecom grounding bus 8. Telecommunication ground wire level 2 the telecommunications infrastructure of a building served by one or more telecommunications rooms. For example, a building contains one equipment room and multiple telecommunications rooms. In addition to all the management requirements in level 1, the management elements of level 2 should also include vertical wiring subsystem, grounding system and fire prevention management. Level 2 can be based on spreadsheet software, specialized management software, or AIM (Automatic Infrastructure Managermet) management system systems. For level 2 management, the following components must be clearly marked: 1. All required parts of level 1 2. Wiring subsystems 2 and 3, vertical backbone 3. Wiring subsystems 2 and 3 cable ports 4. Fire protection location level 3 consists of a telecommunications infrastructure of a park that includes a number of buildings and external facilities. The management elements of level 3 include not only all the management requirements of level 2, but also the signs of each building in the park and the management of the backbone cable system of the park. Bridge space and external subsystems are recommended for management. Level 3 can be based on spreadsheet software, specialized management software, or AIM management system systems. For level 3 management, the following components must be clearly marked: 1. All required parts of level 2. Each building 3. Park backbone cable 4. In addition to the above required options, there are several options for each pair of copper cable and each fiber in the campus backbone cable, for example, the routing level 4 between buildings is made up of telecommunications infrastructure of multiple campuses / locations. In addition to all the management requirements in level 3, the management elements of level 4 need to include the identification of each campus and the elements within the campus. For critical systems, critical buildings, multi-tenant buildings, path, space and building exterior management are strongly recommended. Level 4 can be based on spreadsheet software, specialized management software, or AIM management system systems. 1. For level 4 management, the following components must be clearly marked: 2. All required parts of level 3. In addition to the above required options for each campus and site, there are also options as level 4, such as routing between buildings. 5 the biggest change in the new ANSI/TIA-606-B standard compared with the A version is the addition of an intelligent infrastructure management system, which can use some technologies to monitor and record infrastructure changes. In addition to the basic management foundation and system reliability, how to quickly locate and solve problems in network cabling and equipment problems is very important. The use of intelligent infrastructure management system can avoid problems such as lack of timely maintenance of data, chaotic management and difficult maintenance due to jumper changes in the previous wiring system management process. Intelligent infrastructure management system also has a variety of related technology development with the needs of the market. At present, all kinds of technologies are mainly different ways of reading information, such as link detection technology (10-pin, 9-pin), RFID radio frequency identification technology, CPID embedded microchip marking point detection technology, built-in mechanical switch or micro sensor port monitoring technology. No matter which technology is used, the dual distribution frame structure can better realize the management function of the intelligent infrastructure. There is no special label format in TIA-606-B to specify the technology and software of each different infrastructure management system. These professional infrastructure management software should be able to form labels and export data to other devices or label software to print labels. The intelligent infrastructure management system should be implemented and maintained under certain operational guidance, and include a set of principles that can ensure accurate operation. The standard lists the core requirements that an intelligent infrastructure management system needs to meet: a) automatic record archiving All telecommunications infrastructure elements to be managed in TIA-606-B b) provide a complete record of all connected devices c) provide operational guidance for troubleshooting and resolution d) provide automatic LAN or SAN network connection status query and record e) be able to automatically discover end devices connected to the network And can query and record that the system requires fault tolerance, for example, records will not be lost in the case of a sudden power outage. The system can automatically monitor and manage all jumpers in the system, and when the connection changes, the system can record. If the connection change is not authorized or the wrong change, the system can alarm and record the error in time. The system should also be able to automatically generate reports on the telecommunications infrastructure. In addition to the above core requirements, the intelligent infrastructure management system preferably has the following features: a) automatically discover and track the physical addresses of terminal devices connected to the system; b) the software integrates weak electricity building plan CAD drawings or other types of building floor plans, which makes it easy to query the layout of telecom infrastructure and document record management. If any user port is abnormal, the network management personnel can quickly locate physically, and the management efficiency can be improved. C) the system can generate electronic work orders to authorize and record the increase, movement, decrease and other changes of jumpers, or integrate the work order management system to implement network connection changes, thus reducing the possibility of human error and improving the accuracy and efficiency of work order implementation. D) create the text and labels described in Section 10 e) Integrated power management and monitoring, changes in the operating environment, it is best to use an automatic infrastructure management system in the following systems: a) large and complex buildings and campuses, data centers, etc. (level 2, level 3, level 4) b) need to save human resources costs C) employees do not have enough professional skills and experience to manage telecom cabling d) remote monitoring and management of remote divisions are needed. As recommended by the ANSI/TIA-606-B standard, intelligent infrastructure management systems can be recommended in telecom rooms, equipment rooms and data centers of complex commercial buildings. In the system, efficient electronic work order, intelligent navigation operation, network connection monitoring and alarm, real-time generation of infrastructure reports, automatic location of physical location, network rapid disaster recovery, real-time preparation of document connection, remote network management and so on can greatly improve the efficiency of telecom infrastructure management. Recording and labeling are essential for management. Every time there is an increase, decrease or change in the telecommunications infrastructure, whether it can maintain accurate and timely records affects the effectiveness of management. In the long run, failure to prepare and document changes in a timely manner can lead to costly consequences. Previously, we used to rely solely on manual recording, and personnel changes and shifts will bring potential errors. The intelligent infrastructure management system proposed in TIA-606-B can automatically update document records in real time, and the latest real-time status can be seen. This not only frees IT managers from the traditional time-consuming paper document maintenance, but also eliminates the possibility of manual written record errors. Conclusion the official release of TIA-606-B has a very important guiding significance for telecom infrastructure management. The TIA-606-B standard applies not only to data centers, but also to commercial, residential, industrial and medical institutions. It now establishes guidelines for owners, end users, manufacturers, supervisors, contractors, integrators, builders, and infrastructure managers. At the same time, it makes the management from the traditional way to intelligent management, which gives users convenience and improves the return on investment of telecom infrastructure.
