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 standards@tiaonline.org.

 

T.35 Manufacturer Codes

T.35 codes are globally unique identifiers defined by the ITU-T (International Telecommunication Union – Telecommunication Standardization Sector). These codes are used to signal information about the device originating communications.

Types of T.35 Codes

  • T-series – Fax devices
  • V-series – Modems
  • H-series – Video and multimedia systems

The process for assigning these codes is outlined in ITU-T Recommendation T.35: Procedures for the Allocation of Terminal Codes.

TIA-Assigned Codes: T-series and V-series

TIA is responsible for assigning T-series and V-series T.35 Manufacturer Codes.

To request a T-series or V-series code, please email:
ust35admin@tiaonline.org

View current T-series and V-series assignments:

  • T35 Code Assignments
  • T35 Codes Assignments by Company

CTA-Assigned Codes: H-series

The Consumer Technology Association (CTA) assigns H-series T.35 Manufacturer Codes.

To request an H-series code or view current assignments, visit the CTA website.

If you have questions about T.35 code assignments, feel free to contact us at ust35admin@tiaonline.org.

Partnerships

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.

TIA has also developed agreements with the following organizations:

  • APCO - Association of Public-Safety Communications Officials
  • ANSI - American National Standards Institute
  • ATIS - Alliance for Telecommunications Industry Solutions
