Call for Interest in a new Project for Telecommunications - Telephone Terminal Equipment - Transmission Requirements for Digital Telephones with Headsets

TIA Issues Call for Interest on new Project for Telecommunications- Telephone Terminal Equipment- Transmission Requirements for Digital Telephones with Headsets

Stakeholders Invited to Contact TIA Regarding Participation.

Arlington VA. (May 02, 2013) – The Telecommunications Industry Association (TIA) TR-41.3 Engineering Committee has issued a call for interest for document TIA-920.130-B initially titled Telecommunications- Telephone Terminal Equipment- Transmission Requirements for Digital Telephones with Headsets.  TR-41.3 is developing guidelines to establish audio transmission performance requirements for headset equipped 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 with headsets, previously found in ANSI/TIA-810-B, to the existing wideband (150 to 6800 Hz) requirements in TIA-920.130-A and upgrade the document to ANSI status.  It will also include the option of using send and receive levels as a measure of transmission performance instead of the more traditional send and receive loudness ratings.  The term “wideband” will be dropped from the document title since the revised standard will cover both wideband and narrowband telephones..

The stakeholders may include, but are not limited to:  Manufacturers, specifiers, and users of digital telephones and other communications devices providing voice transmission, regardless of protocol or digital format.  Specifiers may include retail equipment buyers, enterprise and government procurement officers, etc.

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