CableLabs hosted an interoperability testing event around wideband HD
Voice in early December with 11 participating vendors, and also
announced it has signed a collaboration agreement with the Digital
Enhanced Cordless Telecommunications Forum, which maintains standards
for cordless phones.
CableLabs said it has adopted the DECT
Cordless Advanced Technology - Internet and quality (CAT-iq)
specifications as part of its PacketCable HD Voice initiative.
Voice delivers higher-quality voice transmissions by more than doubling
the frequency of range of traditional narrowband voice calls to
"wideband audio" ranges (50 Hertz to 7 Kilohertz).
