TI's DSP-based TNETC47xx ( Puma-4 ) VoCable chipset incorporates advancements to process cellular codecs, setting the stage for fixed mobile convergence with phones that operate on cellular or VoIP connections, depending on the user's choice and proximity to either network. Additionally, its low bit-rate codecs for conferencing channels use half the bandwidth currently consumed for multi-user calls, saving bandwidth for other applications while maintaining high data rates. The TNETC47xx also has advanced fax capabilities, furthering VoIP's potential as a replacement for traditional telephone lines.

"As service providers push for more processing-intensive features such as VoIP, conferencing services, mobility throughout the home and digital TV, the traditional cable modem is evolving into something much more advanced," said Irvind Ghai, director, worldwide marketing for TI's cable group. "It is increasingly important to have a flexible, DSP-based solution at the heart of that device. TI offers the right mix of silicon, software and hardware development platforms and partners with key third parties to keep service providers ahead of the curve."
