Arlington VA. (July 17, 2017) – The Telecommunications Industry Association (TIA) TR-41.3 Engineering Committee on Performance and Accessibility for Communication Devices has issued a call for interest for document ANSI/TIA-470.140 initially titled “Acoustic Echo Control Requirements for Analog Telephones”. TR-41.3 is developing guidelines to address the issue of analog telephones exhibiting delays in the acoustic path. It is requiring that acoustic echo control (AEC) be used to prevent far-end talker echo.
The stakeholders may include, but are not limited to: Analog telephone manufacturers.
TIA actively seeks participation in these projects from the user and general interest communities.
