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).

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).
