  2. TIA Telecommunications Industry Association

  3. TIA The Telecommunications Industry Association (TIA) is the leading trade organization serving the communications and IT industry, with proven strengths in standards development, domestic and international public policy, and trade shows. Through its worldwide activities, TIA facilitates business development opportunities and a competitive market environment. The association provides a forum for its member companies, the manufacturers and suppliers of products and services used in global communications. TIA is accredited by the American National Standards Institute to develop American National Standards used in the industry. TIA represents the communications sector of the Electronic Industries Alliance (EIA).

  10. TR-41 User Premises Telecommunications Requirements

  11. TR-41 Scope Addresses voluntary standards for telecommunications terminal equipment and systems, specifically those used for voice service, integrated voice and data service, and Internet Protocol (IP) applications. The work involves developing performance and interface criteria for equipment, systems and private networks, as well as the information necessary to ensure their proper interworking with each other, with public networks, with IP telephony infrastructures, and with carrier-provided private-line services. It also includes providing input on product safety issues, identifying environmental considerations for user premises equipment, and addressing the administrative aspects of product approval processes. In addition, TR-41 develops criteria for preventing harm to the telephone network that become mandatory when adopted by the Administrative Council for Terminal Attachments (ACTA).
