Eleven industry suppliers took part in a recent interoperability testing event at CableLabs that focused on progress being made around wideband High-Definition Voice (HD Voice). CableLabs also announced it has signed a collaboration agreement with the Digital Enhanced Cordless Telecommunications (DECT) Forum.

CableLabs has adopted the DECT Cordless Advanced Technology – Internet and quality (CAT-iq) specifications as part of its PacketCable HD Voice initiative.

“This collaboration agreement enables cable operators, CableLabs and the DECT Forum to work together to ensure that all HD Voice capable DECT handsets certified worldwide will operate with cable gateways,” said Jean-François Mulé, VP/IP Technologies and Services at CableLabs, in a statement.

During the interop event held December 6-10 at CableLabs, the companies exhibited a high level of interoperability between handsets and base stations. A number of wideband HD voice calls were successfully made using different components from various suppliers. HD voice technology doubles the transmitted bandwidth of one’s voice by capturing twice the speech information of a standard phone call.

The interop specifically addressed DECT CAT-iq 2.0 technology. This is a technology designed to enhance quality of digital voice increasing engagement for both consumer and business voice.

Participating suppliers were Binatone, BroadSoft, CCT, DSP Group, Lantiq, Panasonic, RTX, Samsung, SMC Networks, Technicolor and VTech.
