Texas Instruments Introduces New Voice-Over-Cable Chipset
Texas Instruments yesterday announced the availability of its advanced voice-over-cable (VoCable) chipset and new Wideband DOCSIS reference design which are called to help drive the global growth of Voice over IP (VoIP).
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 bitrate 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.
In addition to the TNETC47xx chipset, TI announced it has developed a Wideband DOCSIS reference design that lets equipment manufacturers and service providers evaluate system architectures today, speeding time to market. This will allow multi-service operators (MSOs) to quickly offer advanced features and enhanced cable modems, once the standard is approved. The reference design includes documentation, board schematics, production files and DOCSIS software.
Wideband DOCSIS technology will incorporate multiple down and up streams in a single modem, providing higher broadband speeds and greater bandwidth to both business and consumer subscribers. As the standard evolves to include voice, the increased bandwidth and enhanced performance of DOCSIS 3.0 modems will support VoIP conversations and video downloading without impacting the stream of information delivered to and from the home or office.
TI´s TNETC47xx chipset will sample in the fourth quarter of 2005. TI also expects to deliver its first Wideband DOCSIS reference designs in the same time frame.
