22、ents on when and where to use this space. This maintains structured cabling while providing additional flexibility offered by a TE in certain situations. Revisions are identified in the following text with additions shown in bold italics and deletions shown as strikeout. 2 SCOPE This Standard specif

23、ies minimum requirements for telecommunications cabling within an environment that uses telecommunications enclosures in its infrastructure. A telecommunications enclosure as defined in ANSI/TIA/EIA-569-B is a case or housing that is dedicated to the telecommunications function and related support f

24、acilities. Just like a telecommunications room, the telecommunications enclosure is a common access point for backbone and building pathways. The use of telecommunications enclosures is a specific implementation and not a general case. A telecommunications enclosure is intended to serve a smaller fl

25、oor area than a telecommunications room (see TIA-EIA 569-B). One must plan in advance if a telecommunications enclosure is needed and make sure that the introduction of this space will not create issues regarding the structured cabling systems, the management and administration of the installation.

26、TEs may be used as an addition to the minimum requirements of TIA-569-B that require one telecommunications room per floor and recommend an additional TR for each area up to 1000 m2(10000 ft2). The number of TRs required or recommended in TIA-569-B is not reduced by the use of TEs. TEs may also be u

27、sed for serving certain environments like classrooms, entrance lobbies, or historic buildings. This Standard provides requirements to retain the integrity of a structured cabling system, when a telecommunications enclosure is required. 3 CLAUSE REVISIONS 1.5 Telecommunications cabling system structu

It depicts the relationship between the elements and how they are configured to create a total system. The elements of the telecommunications ca

35、ndards. Specific requirements are found in the normative clauses of this Standard. For the purposes of this Standard, the following definitions apply. backbone: 1) A facility (e.g., pathway, cable or conductors) between any of the following spaces: telecommunications rooms, telecommunications enclos

36、ures, common telecommunications rooms, floor serving terminals, entrance facilities, equipment rooms, and common equipment rooms. 2) in a data center, a facility (e.g. pathway, cable or conductors) between any of the following spaces: entrance rooms or spaces, main distribution areas, horizontal dis

37、tribution areas, telecommunications rooms.(TR-42.1.1) building backbone: Pathways or cabling between telecommunications service entrance rooms, equipment rooms, telecommunications rooms, or telecommunications enclosures within a building. centralized cabling: A cabling configuration from the work ar

38、ea to a centralized cross-connect using pull through cables, an interconnect, or splice in the telecommunications room or telecommunications enclosure. enclosure, telecommunications: A case or housing for telecommunications equipment, cable terminations, or horizontal cross-connect cabling. intrabui

39、lding telecommunications backbone: This term is out dated term. See building backbone. space (telecommunications): An area used for housing the installation and termination of telecommunications equipment and cable, e.g., common equipment rooms, equipment rooms, common telecommunications rooms, tele

42、ect in the telecommunications room or when used, in the telecommunications enclosure. The horizontal cabling includes horizontal cables, telecommunications outlet/connectors in the work area, mechanical terminations, and patch cords or jumpers located in the telecommunications room or when used, in

43、the telecommunications enclosure, and may include multi-user telecommunications outlet assemblies and consolidation points. NOTE - The term “horizontal“ is used since typically the cable in this part of the cabling system runs horizontally along the floor(s) or ceiling(s) of a building. The followin

44、g list of common services and systems should be considered when the horizontal cabling is designed. (The list is not intended to be complete.) a) Voice telecommunications service b) Premises switching equipment c) Data communications d) Local area networks (LAN) e) Video f) Other building signaling

45、systems (building automation systems such as fire, security, HVAC, EMS, etc.) In addition to satisfying todays telecommunications requirements, the horizontal cabling should be planned to reduce on-going maintenance and relocation. It should also accommodate future equipment and service changes. Aft

46、er construction of the building, the horizontal cabling is often much less accessible than the backbone cabling. The time, effort, and skills required for changes can be extremely high. In addition, access to the horizontal cabling frequently causes disruption to occupants and their work. These fact

47、ors make the choice and layout of horizontal cable types very important to the design of the building cabling. Consideration should be given to accommodating a diversity of user applications in order to reduce or eliminate the probability of requiring changes to the horizontal cabling as user needs

48、evolve. The pathways and spaces shall be designed and installed to support horizontal cabling in accordance with the requirements of ANSI/TIA/EIA-569-A ANSI/TIA/EIA-569-B. 4.2 Topology The horizontal cabling shall be installed in a star topology as shown in figure 4-1. Each work area telecommunicati

49、ons outlet/connector shall be connected to a horizontal cross-connect in a telecommunications room or when used, in the telecommunications enclosure via the horizontal cable. A telecommunications room or when used, a telecommunications enclosure should be located on the same floor as the work areas served. Some networks or services require applications-specific e
