The TIA-569-E standard, published by the Telecommunications Industry Association (TIA), provides guidelines for the design and installation of commercial building telecommunications cabling systems. The standard focuses on ensuring that cabling systems are designed and installed to support a wide range of telecommunications services and applications.
To understand the importance of the "E" revision, one must first grasp the role of the TIA-569 standard. Titled "Telecommunications Pathways and Spaces," this standard is the architectural counterpart to the TIA-568 cabling standard. While TIA-568 dictates what cable to use and how to terminate it, TIA-569 dictates where that cable goes and what physical environment it inhabits. It outlines the requirements for equipment rooms, telecommunications rooms, backbone pathways, and horizontal pathways. Without these guidelines, a building’s cabling infrastructure would be chaotic, prone to physical damage, and incapable of supporting future technological upgrades. tia-569-e pdf
