TIA creates four new standards for analog HD voice phones

The Telecommunications Industry Association (TIA) has approved four new standards to cover requirements for analog HD phones to connect to ATAs, MTAs or voice gateways to provide HD voice services via IP.

TIA’s Engineering Committee on Analog and Digital Wireless Terminals (Hmm,there’s an anarchic phrase) TR-41.3 has issued a “call for interest” for the following documents:

ANSI/TIA-470.340 initially titled "Telecommunications – Telephone Terminal Equipment – Feature Performance Requirements for Wideband Analog Telephones Used with VoIP Services".  Addresses wideband feature performance requirements such as the terminal notifying the ATA, MTA, or VG to which it is connected that it has wideband capability and determining whether it should operate in wideband or narrowband mode based on information received from the connected device about the capabilities of the far end terminal.

ANSI/TIA-470.112 initially titled "Telecommunications – Telephone Terminal Equipment – Transmission Requirements for Wideband Analog Telephones with Handsets". Addresses wideband voice transmission requirements specific to analog telephones equipped with handsets."

ANSI/TIA-470.122 initially titled "Telecommunications – Telephone Terminal Equipment – Transmission Requirements for Wideband Analog Telephones with Speakerphones". Wideband voice transmission requirements specific to analog telephones equipped with speakerphones."

ANSI/TIA-470.132 initially titled "Telecommunications – Telephone Terminal Equipment – Transmission Requirements for Wideband Analog Telephones with Headsets". Wideband voice transmission requirements specific to analog telephones equipped with headsets.”

Parties potentially interested in the new standards “may include, but are not limited to: corded and cordless telephone manufactures, analog terminal adapter manufacturers, multimedia terminal adapter manufactures, voice gateway manufacturers, VoIP service providers, DSL and cable Internet service providers, DECT / CAT-iq chipset makers, telephone controller IC makers, and VoIP telephone manufacturers. “

The new standards will become part of the TIA-470 series of analog telephone documentation.
