TIA/EIA-569-A-1

Perimeter Pathway Addendum

This addendum deals with the constriction, applications, premises design and installation of perimeter pathways also known as surface raceway systems. It describes both single and multi channel systems mounted on walls at a variety of heights and directions. The sizing of such pathways are based on 40% fill for initial installations but allows up to 60% fill for moves adds or changes to the installed cabling system during its life cycle. Fittings for Perimeter raceway systems must allow for the band radius requirements of the installed cable.

TIA/EIA-569-A-2

Furniture Pathway Fill Addendum

The sizing of such pathways are based on 40% fill for initial installations but allows for up to 60% fill for moves, adds and changes to the installed cabling system during its life cycle. Furniture fittings such as outlets and connectors used to terminate the installed cables need to be considered when determining the percentage of fill. Fish and pull techniques may result in reduced capacity of the pathway as compared to furniture manufacturers which allow placing cables into the pathways.

TIA/EIA-569-A-3

Revision to subclause 4.3, “Access Floor” of TIA/EIA-569-A

Introduces low profile floors as compared to standard height floors. Low profile floors are 6“ or lower while standard height floors are 6“ or greater. This revision describes the use of access floors as it refers to guidelines and installation.

TIA/EIA-569-A-4

Addendum 4 to ANSI/TIA/EIA-569-A Poke-Thru Devices

A poke-thru is a device for routing cables through a floor while maintaining the fire-rating integrity of the floor. These devices are an option for routing horizontal cables when other pathway types are not practical. Types include flush floor mount and those that rise up above floor level, also known as pedestal, raised, tombstone or monument.

TIA/EIA-569-A-5

Addendum 5 to ANSI/TIA/EIA-569-A

This addendum revisits underfloor systems including cells, trenches, and ducts to replace subclause 4 of the ANSI/TIA/EIA-569-A standard.

TIA/EIA-569-A-6

Addendum 6 Multi-Tenant Pathways and Spaces

This addendum deals with the growing trend of building owners installing telecommunications backbone cabling for use by tenants. This addendum names pathways and spaces used by these backbone cables.

TIA/EIA-569-A-7

Addendum 7 Cable Trays and Wireways

This addendum replaces sub-clause 4.5 of ANSI/TIA/EIA-569-A. It was modified to clarify industry issues with cable fill for cable tray systems.
