Engineering Committee Scope Manual

TIA's Standards and Technology Department is composed of formulating groups consisting of Engineering Committees, their subcommittees, and working groups. These formulating groups develop voluntary industry standards and specifications for telecommunications equipment and fiber optic products.

The scope statements below focus on the standards and specification writing mission of the committees and their subcommittees and working groups. All TIA engineering committees have the additional missions of:

  • providing technical studies and support to their sponsoring TIA divisions;
  • formulating of inputs, where appropriate, to regional and international standards bodies and;
  • formulating of engineering and technical inputs into government entities as related to the standards in their scope, or as requested by the sponsoring TIA division or Standards and Technology Department.

Formulating groups scopes may be revised or reordered from time to time in order to carry out the mission of the committee as set forth in the Engineering Manual.
