Description / Abstract:



Modem telecommunications require an effective infrastructure within a building to support the wide variety of systems that rely on the electronic transport of information. This infrastructure encompasses telecommunications equipment spaces, cable pathways, telecommunications wiring and termination hardware, grounding for telecommunications, and other devices. The infrastructure provides the basic support of the distribution of all information within the building. Telecommunications, as used in this Standard, refers to all forms of information that are conveyed within the building (e.g., voice, data, video, alarms, environmental control, security, audio, etc.).

The grounding and bonding approach recommended in this Standard is intended to work in concert with the cabling topology as specified in ANSIEIAITIA-568 (telecommunications wiring standard) and installed in accordance with ANSIIEIAITIA-569 (telecornmunications pathways and spaces standard). The requirements specified in this Standard, in conjunction with a basic understanding of the grounding concepts, will aid the user in achieving a reliable grounding solution when applied to specific telecommunications grounding installations.


The purpose of this Standard is to enable the planning, design, and installation of telecommunications grounding systems within a building with or without prior knowledge of the telecommunication systems that will subsequently be installed. This telecornmunications grounding and bonding infrastructure supports a multivendor, multiproduct environment as well as the grounding practices for various systems that may be installed on customer premises
