The Telecommunications Industry Association (TIA) TR-41.3 Engineering Committee on Analog and Digital Wireline Terminals has issued a call for interest for document ANSI/TIA-912-C initially titled “Telecommunications – IP Telephony Equipment – Voice Gateway Transmission Requirements”.
This standard covers transmission requirements for voice gateways (VGs) that provide routing functions between telephones, traditional public and private networks, and modern packet-based networks. VGs include packet-based enterprise equipment, residential gateways, ADSL-based Integrated Access Devices (IADs), and cable-based Multimedia Terminal Adapters (MTAs). The main purpose of this revision is to add requirements for supporting wideband (nominally 100 to 7,000 Hz) analog telephones that may be connected to voice gateways for providing High Definition (HD) voice services such as those available using Voice over Internet Protocol (VoIP).
The stakeholders may include, but are not limited to: Manufacturers of enterprise and residential gateways, Integrated Access Devices (IADs) and Multimedia Terminal Adapters (MTAs); traditional public and private network service providers, packet-based network service providers, and ADSL and cable VoIP service providers.
TIA is actively seeking participation in these projects from the user and general interest communities.
