Texas Instruments Inc. has announced the newest members of its VoIP gateway silicon and software solutionsthe TNETV2664, TNETV2666, TNETV2686 and TNETV2689that were designed to enable equipment manufacturers to achieve higher channel densities with improved voice quality.

The new gateway solutions are powered by TI's TMS320C64x+TM DSP that increases performance for VoIP and video encode, decode and transcode applications. The flexible architecture of these new solutions allows equipment manufacturers to transition to a common hardware and software architecture that scales from eight to several hundreds of channels while supporting advanced voice and video features.

The solutions support an Ethernet interface and full IP encapsulation that allows the DSPs to put voice media directly on the network. This integration enables manufacturers to choose a smaller, more cost-effective host processor, thereby simplifying their hardware design and reducing overall BOM costs. The new gateway solutions include pin-compatible options with different channel densities, which give equipment manufacturers the ability to design a common hardware architecture that can scale across a range of product configurations and applications.

As the first of TI's medium-density gateway solutions to operate on the C64x+ DSP core, manufacturers will now be able to integrate video capabilities to their products and still support voice and fax communications between TDM and packet telephony networks. The improved processing power enabled by the C64x+ architecture combined with increased on-chip memory improves voice gateway performance while enabling higher channel densities.

"The power and performance of TI's C64x DSP enables our newest family of enterprise gateway solutions to deliver improved voice transmission and high-quality video," said Fred Zimmerman, director of CPE solutions for TI's voice solutions business unit. "We are listening to our enterprise and service provider customers' needs and equipping them with the most sophisticated voice gateway solutions that will allow them to expand their application offerings and meet the growing demands of service providers."
