TR-41 and TIA-4953 Compliant Logo

The amplified telephone industry has, for many years, encountered confusion and complaints regarding amplified telephone products and their advertised claims for ‘gain’ and other acoustic performance parameters. In response to these issues, TIA's TR-41 Engineering Committee developed TIA-4953, Amplified Telephone Measurement Procedures and Performance Requirements, which was published in August 2012. The standard includes requirements for the acoustic performance of a telephone to meet the needs of people with hearing loss. The TIA is the owner of the TIA-4953 Compliant Logo for use by companies wishing to self-certify that products meet the requirements of the TIA-4953 Standard for high-gain amplified telephones. TIA is offering a limited, transferable, revocable, world-wide license to use the logo in connection with equipment that conforms to the Standard.

Customers will be assisted by having a uniform means to readily identify TIA-4953 compliant products suitable for their hearing loss category. For additional information and to receive a copy of the License Agreement, please contact Standards Management at (703) 907-7735.

Exploratory Focus Group on Fuel Cell Standards for ICT Infrastructure

TIA's Fuel Cell Focus Group provides a forum for fuel cell companies, mobile network operators, cell site leasing companies, engineering firms, government entities, and others to develop documents that can provide the ICT industry as a whole with a guide to the technical considerations and benefits of fuel cell deployment in support of wireless and other ICT infrastructure.

The Fuel Cell Focus Group recognizes that there are numerous standards for hydrogen fuel cell safety, which are written for generic use that range from automotive refueling stations to main alternative fuel supplies. The scope of this Focus Group is to develop a comprehensive understanding of the fuel cell codes for both stationary and mobile fuel cells for specific use with telecom, wireless, datacom, emergency 911, police radio, security and surveillance, and catastrophic infrastructure for commercial, military, or residential use at ground level, on rooftop, or on platforms applications for backup, supplemental and/or alternative electric power sources as well as associated fuel storage requirements.

The Focus Group has completed its Reference Guide, "Guide for Fuel Cell Installations for Wireless and Information and Communications Technology (ICT) Infrastructure." The FCFG will continue its efforts to build a second document which is intended to be a user’s guide for deployment of stationary fuel cells and will be focused more on guidance for operating stationary fuel cells.


TR-8 and APCO Project 25 Public Safety Standards
Recognizing the need for common standards for first responders and homeland security/emergency response professionals, representatives from the Association of Public Safety Communications Officials International (APCO), the National Association of State Telecommunications Directors (NASTD), selected federal agencies and the National Communications System (NCS) established Project 25 (PDF), a steering committee for selecting voluntary common system standards for digital public safety radio communications. TIA TR-8 facilitates such work through its role as an ANSI-accredited Standards Development Organization (SDO) and has developed in TR-8 the 102 series of technical documents. These standards directly address the guidelines of the Communications Assistance for Law Enforcement Act (CALEA).

TR-41 and Administrative Council for Terminal Attachments (ACTA)
An organization established to adopt technical criteria for terminal equipment developed by ANSI-accredited standards development organizations and maintains a registration database of equipment approved as compliant with the technical criteria. ACTA is directly supported by the work of TIA's TR-41 engineering committee, which creates standards for terminal attachments.

TR-45 and Third Generation Partnership Project 2 (3GPP2)
The standardization group for CDMA2000 technology. 3GPP2 was formed out of the International Telecommunication Union's (ITU) International Mobile Telecommunications "IMT-2000" initiative, covering high speed, broadband, and Internet Protocol (IP)-based mobile systems featuring network-to-network interconnection, feature/service transparency, global roaming and seamless services independent of location. 3GPP2 is directly supported by the work of TIA's TR-45 engineering committee, which develops wireless standards for CDMA devices. (CDMA2000 / UWC-136)

TR-45 and International Telecommunication Union (ITU)
As the global focal point for governments and the private sector, ITU's role in helping the world communicate spans three core sectors: radio communication (ITU-R), standardization (ITU-T), and development (ITU-D). Formulating groups within ITU-T have previously adapted TIA standards.
