Table below provides global perspective of which standards apply for different applications and environments.

For this month’s column I wanted to provide an overview of the key telecommunications cabling standards that are published by TIA and the interrelationship of these standards with their international counterparts.
I pulled this information from various sources to bring it up to date at the time of this writing. It gives a global perspective of which standards apply for different applications and environments. A number of experts that participate in the various TIA TR 42 subcommittees also participate in the ISO/IEC JTC1 SC25 subcommittee and associated working groups.
A liaison report is provided at the TIA opening plenary on the status of the international standards developments.
Also, TIA TR 42 works through the US TAG (Technical Advisory Group) to facilitate the exchange of technical information. The TIA and international standards are harmonized as much as possible. A good example of harmonization at work is the standardization of the 8-pin modular connector for the information outlet and wiring configuration. This ensures that an information technology device can be plugged in anywhere in the world without requiring a special adapter.
Every standard that is published by TIA has a list of normative standards that, through reference, constitute provisions of the Standard. For more detailed information on these documents consult the TIA web site at http://www.tiaonline.org/standards/or the ISO/IEC JTC 1/SC 25 web site at http://sc25.iec.ch/
