本标准中使用的电信是指所有形式信息的传输（例如，语音、数据、视频、安全、音频、工业、楼宇控制）。用于支持这些依赖电子信息传输的各种系统的电信设备需要有效的建筑基础设施。该基础设施包括空间、通道、电缆、连接硬件以及连接和接地系统。对于任何电信设备或系统的可靠运行，无论采用何种布线技术或介质，连接和接地（接地）都至关重要。本标准侧重于基础设施的连接和接地部分。注:本标准中使用的北美术语“接地”等同于国际术语“接地”。 本标准中的连接和接地方法旨在与TIA工程委员会TR-42中规定的场所布线一致。本标准中规定的要求，以及对连接和接地概念和方法的基本理解，将有助于实现适用于电信安装的可靠解决方案。在电信行业中，存在几种连接和接地信息来源。例如，NECA®规定了有关设备和系统连接和接地的安全方面的要求。另一个例子是ATIS 0600318，即应用于客户结构或建筑物入口处电信网络设备的电气保护，它提供了有关连接和接地的信息，以支持电气保护考虑。 目的本标准的目的是在事先了解或不了解随后将安装的电信系统的情况下，允许并鼓励在场所内规划、设计和安装通用电信连接和接地系统。虽然本标准主要旨在为新建筑的设计提供指导，但本标准可用于现有建筑的翻修或翻新处理。提供设计要求和选择，使设计师能够做出明智的设计决策。

Telecommunications, as used in this Standard, refers to the transmission of all forms of information (e.g., voice, data, video, security, audio, industrial, building control). Telecommunications equipment used to support these wide varieties of systems that rely on the electronic transport of information require an effective building infrastructure. This infrastructure encompasses spaces, pathways, cables, connecting hardware, and a bonding and grounding system. For reliable operation of any telecommunications equipment or system, bonding and grounding (earthing) is essential regardless of the cabling technology or media. This Standard focuses on the bonding and grounding portion of this infrastructure.NOTE: The North American term "grounding" that is used in this Standard is equivalent to the international term "earthing".The bonding and grounding approach in this Standard is intended to work in concert with premises cabling specified within TIA Engineering Committee TR-42. The requirements specified in this Standard in conjunction with a basic understanding of bonding and grounding concepts and methodologies will aid in achieving a reliable solution when applied to telecommunications installations.Several sources of bonding and grounding information exist within the telecommunications industry. For example, the NECA® specifies requirements regarding the safety aspects of bonding and grounding of equipment and systems. Yet another example is that of ATIS 0600318,Electrical Protection Applied to Telecommunications Network Plant at Entrances to Customer Structures or Buildings, which provides information on bonding and grounding to support electrical protection considerations.PurposeThe purpose of this Standard is to enable and encourage the planning, design, and installation of generic telecommunications bonding and grounding systems within premises with or without prior knowledge of the telecommunications systems that will subsequently be installed. While primarily intended to provide direction for the design of new buildings, this Standard may be used for existing building renovations or retrofit treatment. Design requirements and choices are provided to enable the designer to make informed design decisions.
