2.范围2。1概述2。1.1本标准的范围仅限于商业建筑设计和施工的电信方面，包括建筑内部和建筑之间的电信考虑。电信方面通常是电信媒体放置的路径，以及用于终止媒体和安装电信设备的与建筑物相关的房间和区域。2.1.2本标准中同时使用了建筑和电信术语，这可能会给在一个领域有经验但在另一个领域可能没有经验的读者带来一些困难。读者可以通过记住本标准没有标准化媒体或设备来减少混淆； 它只对电信媒体和设备所在建筑物内部和建筑物之间的通道和空间进行了标准化。2.1.3尽管范围仅限于建筑设计的电信方面，但本标准对其他建筑服务的设计有重大影响，如电力和暖通空调。该标准还影响建筑物内的空间分配。2.1.4本标准不包括建筑设计的安全方面；读者可参考本安全和建筑规范标准。其他规范和标准也可能适用于电信通道和空间的安装。 2.1.5本标准不包括需要任何特殊类型安全措施的任何电信系统。2.1.6本标准认可单租户和多租户建筑。根据本标准的要求，占用通常发生在基地建筑建造和供应之后；然而，多租户建筑中个别租户的独特需求可能需要通过基础建筑设计中提供的额外电信通道和空间设施来满足。预计在入住时，每个租户将按照ANSI/TIA/EIA设计电信布线- 568-A。因此，建筑设计可能还包括通道和空间，以支持每个租户的两级主干布线层次结构。2.2基本建筑构件2。2.1电信对商业建筑内和商业建筑之间的大部分区域都有影响。由于这一点，加上建筑物的使用寿命可能长达几十年，因此，新建或改建建筑物的设计和施工非常重要，以避免过时。正确地这样做意味着，在建筑物的使用寿命期间，所产生的建筑物能够对电信媒体和系统中发生的许多正常变化做出响应。 2.2.2图2.2-1说明了主要电信通道与建筑内空间元素之间的关系。以下标准包含的条款通过在本文中引用而构成本标准的条款。出版时，所示版本有效。所有标准都会进行修订，鼓励根据本标准达成协议的各方调查是否可能采用以下所示标准的最新版本。ANSI和TIA保留其发布的当前有效国家标准的登记册。-ANSI/TIA/EIA-568-A，商业建筑电信布线标准，1995年。 （参考D.5）。-ANSI/TIA/EIA-606，《商业建筑电信基础设施管理标准》，1993年。（参考D.6）。-ANSI/TIA/EIA-607，商业建筑电信接地和连接要求，1994年。（参考D.7）。

2 Scope2.1General2.1.1The scope of this Standard is limited to the teleco mmunications aspect of commercial building design and construction, encompassing telecommunications considerations both within and between buildings. Telecommunications aspects are generally the pathways into which telecommunications media are placed and the rooms and areas associated with the building used to terminate media and install telecommunications equipment.2.1.2Both architectural and telecommunications terminology are used in this Standard, which may cause some difficulty to readers experienced in one area but perhaps not in the other. The reader can reduce confusion by remembering that this Standard does not standardize the media or equipment; it only standardizes the pathways and spaces within and between buildings into which telecommunications media and equipment are placed.2.1.3Although the scope is limited only to the telecommuni cations aspect of building design, this Standard significantly influences the design of other building services, such as electrical power and HVAC. This Standard also impacts space allocation within the building.2.1.4The Standard does not cover safety aspects of building design; the reader is directed to the introduction of this Standard fo r safety and building code references. Other codes and standards may also apply to the installation of telecommunications pathways and spaces.2.1.5This Standard does not cover any telecommunications systems that require any special types of security measures.2.1.6Both single- and multitenant buildings are recognized by this Standard. Occupancy usually occurs after the base building has been constructed and provisioned, based on the requirements of this Standard; however, the distinct needs of individual tenants in a multitenant building may need to be accomodated by additional telecommunications pathway and space facilities beyond those provided in the base building design. It is expected that, at occupancy time, each individual tenant will design the telecommunications cabling in conformace to ANSI/TIA/EIA-568-A. As a result, the buildout design may also include pathways and spaces to support a two-level backbone cabling hierarchy for each tenant.2.2Basic Building Elements2.2.1Telecommunications has an impact on most every area within and between commercial buildings. Because of this and the additional fact that the useful life of a building may span many decades, it is very important that the design and construction of new or remodeled buildings be done to avoid obselescence. Doing this properly means that the resulting building is responsive t o the many normal changes that occur in both telecommunications media and systems over the life of the building.2.2.2Figure 2.2-1 illustrates the relationship between the major telecommunications pathway and space elements within a building.The following standards contain provisions which, through reference in this text, constitute provisions of this Standard.
