DALLAS -- Texas Instruments Inc. today announced bundled software and digital signal processor solutions for a range of voice over Internet protocol (VoIP) systems, and the Dallas company said it aims to be the first DSP supplier to integrate 672 channels on a chip for T3 capabilities in the second half of 2001.
TI's new VoIP technology roadmap also shows OC-3--or 2,016 channels--on a chip being achieved in the third quarter of 2002.
Dallas-based TI and its Telogy Networks unit in Germantown, Md., rolled out complete integrated solutions for VoIP systems in customer premise equipment, small-to-medium enterprise systems, and high-density carrier-class gear. Managers with Telogy--which was acquired TI in 1999 (see story), said today's announcement was the biggest VoIP rollout this year planned by TI.
Currently, Telogy's software is installed in 200 designs in the growing VoIP market segment, said Nancy Goguen, vice president of marketing for Telogy Networks. TI also claims that over 80% of VoIP products in use or in development today are based on its technology.
While the number of competitors is growing in the VoIP field, TI believes its has a number of key advantages over other suppliers, including its strong position in the digital signal processor markets. But the chip company also is promoting itself as the only supplier offering complete integrated software, full technical support, and indemnification with its portfolio of patents and technology rights to VoIP.
"We think we have the strongest position here in the industry," stated Dennis Gatens, product management director at Telogy in Germantown. Telogy's software packages cover carrier class PCM, echo cancellation, packet playout software, tone processing, voice activity detection/comfort noise generation, fax relay, and other functions.
TI's current customer premise equipment (CPE) solution integrates a 100-MHz DSP and 47-MHz RISC processor (an ARM7 core) with memory and peripheral functions for up to four voice/fax channels. "This is an optimized solution for CPE, SOHO (small office, home office), and service-specific Internet solutions in the future," Gatens said.
A small-to-medium enterprise (SME) solution is being offered with a dual DSP engine and a 125-MHz RISC processor (an R-4000 MIPS-based core) along with memory and other functions. The SME solution will be available in the third quarter of 2001, priced at $2.44 per channel, including Telogy software, in quantities of 100,000.
For carrier-class VoIP systems, TI is now offering 48-channel solutions packed in a 12-by-12-mm package consuming less than 11-mW per channel. With software, the high-density VoIP solutions start at $2.89 per channel in quantities of 100,000. Samples of a T3 (for 672 channels) will be available in the second half of 2001, according to TI. The OC-3 (2,016 channels) single-chip solution is set to be introduced in 2002.
