ANSI/TIA-568

ANSI/TIA-568 is a technical standard for commercial building cabling for telecommunications products and services. The title of the standard is Commercial Building Telecommunications Cabling Standard and is published by the Telecommunications Industry Association (TIA), a body accredited by the American National Standards Institute (ANSI).

As of 2024, the revision status of the standard is ANSI/TIA-568-E, published 2020, which replaced ANSI/TIA-568-D of 2015, revision C of 2009, revision B of 2001, and revision A of 1995, and the initial issue of 1991, which are now obsolete.[1][2][3]

Perhaps the best-known features of ANSI/TIA-568 are the pin and pair assignments for eight-conductor 100-ohm balanced twisted pair cabling. These assignments are named T568A and T568B.
