The TIA has published the ANSI/TIA-569-E standard, Telecommunications Pathways and Spaces. The “E” revision supersedes the 569-D standard, which was published in 2015. ANSI/TIA-569-E was developed by the TIA’s TR-42.3 Subcommittee. Major changes from the previous edition include updated references; incorporation of revised temperature and humidity requirements originally published in ANSI/TIA-569-D-1; and incorporation of additional pathway and space considerations for supporting remote powering over twisted-pair cabling originally published in ANSI/TIA-569-D-2.
