Telecommunications – Communications Products – Transmission Requirements for Digital Interface Communications Devices with Handsets
Stakeholders Invited to Contact TIA Regarding Participation.
The Telecommunications Industry Association (TIA) TR-41.3 Engineering Committee on Analog and Digital Wireline Terminals has issued a call for interest for document TIA-920.110-B initially titled Telecommunications - Telephone Terminal Equipment - Transmission Requirements for Digital Telephones with Handsets. During the TIA TR-41.3 meeting in Savannah GA the week of February 8th, 2015 the committee voted to update the title of TIA-920.110-B to become Telecommunications – Communications Products – Transmission Requirements for Digital Interface Communications Devices with Handsets.
The updated title reflects broader applicability of communication products in addition to telephones.
This standard establishes audio transmission performance requirements for handset equipped communications devices 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) devices. These devices may be connected through modems, voice gateways, wireless access points, or PBXs, or they may be personal computer-based communications devices. This revision will add updated requirements for narrow band (300 to 3400 Hz) communications devices with handsets, previously found in ANSI/TIA-810-B, to the existing wide band (150 to 6800 Hz) requirements in TIA-920.110-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 wide band and narrow band devices.
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.
To inquire about participating in TIA standards developing efforts, please contact the TIA Technology & Standards Department at 703-907-7000 or via e-mail at standards@tiaonline.org.
A major function of the Telecommunications Industry Association (TIA) is the writing and maintenance of voluntary industry standards and specifications. These activities are carried out by the volunteer members of TIA engineering committees. On the public engineering committee pages, users will find recent meeting reports, agendas and notices for upcoming meetings, as well as links to some of the most popular standards from each committee.
