TIA Issues (2) New Telecommunications - Communications Products Standards

Arlington, VA (October 27, 2015) – The Telecommunications Industry Association, which develops standards for the information and communications technology industry, has released two new documents:

These standards provide an overview of the structure of the ANSI/TIA-920 series of standards that establish audio transmission performance requirements for digital telephones regardless of protocol or digital format. Transmission may be over any digital interface including Local or Wide Area Networks, Universal Serial Bus (USB), Firewire/IEEE Std 1394, public ISDN or digital over twisted pair wire. This includes TDM-based and packet-based (e.g. VoIP) telephones. These telephones may be connected through modems, voice gateways, wireless access points, or PBXs, or they may be personal computer-based telephones. This revision will add updated requirements for narrowband (300 to 3400 Hz) telephones, previously found in ANSI/TIA-810-B, to the existing wideband (150 to 6800 Hz) requirements in the TIA-920-A series and upgrade the series to ANSI status. The term “wideband” will be dropped from the document title since the revised standard will cover both wideband and narrowband telephones.

  • TIA-920.000-B Telecommunications - Communications Products - Overview of Transmission Requirements for Digital Interface Communications Devices.
  • ANSI/TIA-920.110-B Telecommunications - Communications Products - Transmission Requirements for Digital Interface Communications Devices with Handsets.

TIA-920.000-B and ANSI/TIA-920.110-B were formulated under the cognizance of the TIA TR-41 Performance and Accessibility for Communications Products, TR-41.3 Analog and Digital Wireline Terminals subcommittee.

For more information about TR-41 and how to participate in standards development with TIA, contact Marianna Kramarikova at standards@tiaonline.org.

TIA actively seeks participation in these projects from the user and general interest communities.
