New Feature Rich IP Phone Chip from Texas Instruments Raises the Bar for Performance with Advanced Quality and Security

TI's Latest Addition to IP Phone Product Family to Considerably Enrich the VoIP Experience for Businesses of all Sizes

BOSTON, Sept. 12- Texas Instruments Incorporated (NYSE:TXN) (TI) today announced a full-featured Gigabit Ethernet IP phone software and silicon solution that incorporates robust security and enhanced voice quality features to meet the needs of small, medium and large business Voice over IP (VoIP) users. TI's newest IP phone System-on-a-Chip (SoC) is designed on a flexible and powerful digital signal processing (DSP) platform that reduces development costs and helps speed manufacturers' time to market in developing new IP phone products that will increase productivity as well as lower their cost of communications.

"As more companies migrate to IP communications, they will require systems that are feature-rich to support day-to-day business functions, while providing high-quality voice," said Steve Raab, director IP Telephony Research at Dell'Oro Group. "To support these advanced requirements, IP phones must be powerful enough to offer advanced features such as wideband multi-party conferencing, enhanced security support and fax terminal adapter."

At the core of TI's TNETV1051 solution is a flexible 150MHz DSP and a 300MHz RISC processor, with increased processing capability to enable high- quality voice transmission, enhanced security features and additional software applications as required by customers. As the market for enterprise IP phones continues to grow and the demands for more robust features on IP-based devices becomes evident, TI's digital signal processing platform enables powerful and unique applications on IP phones that were previously unachievable. For example, the TNETV1051 can support multiple wideband codecs on an IP phone, including four-way wideband conferencing. With wideband codecs, audio bandwidth has an expanded range resulting in significant improvements in clarity and naturalness of speech. Users who have placed a call using wideband codec technology often liken the experience to having a face-to-face conversation with someone in the same room.

Emphasizing convergence in its VoIP platform, the TNETV1051 also offers a series of gateway-like features on the platform, such as FXS and T.38 fax relay, enabling faxes to be sent to and from IP phone connections, or from an analog phone to an IP phone. With security becoming an increasing concern among both manufacturers and end users, TI has integrated a unique Static Packet Filter (SPF) in its IP phone platform to provide protection against some of the most common forms of Layer 3 and Layer 4 Denial of Service (DoS) attacks, improving existing security features for IP communications. As more businesses transport data over IP networks, deploying robust security solutions to address points of vulnerability is essential. DoS attacks can compromise data transmission, disable voice service and severely impair the functionality of IP networks. TI's SPF addresses these potential intrusions and gives business users the comfort and assurance their network is secure. An integrated 3-port Gigabit Ethernet switch further eases network deployment by continuing to enable a single Ethernet drop to an office without limiting bandwidth to the PC.

"TI has been developing technology that powers the VoIP industry for over a decade and has an excellent understanding of the long-term benefits for businesses deploying IP-based equipment, not the least of which are cost savings," said Fred Zimmerman, executive director, VoIP customer premises solutions, TI. "Our newest and most flexible IP phone platform expands on the cost-benefits of VoIP by providing a truly feature-rich product that surpasses traditional desktop phones with exceptional voice quality and unmatched security."

The TNETV1051 utilizes TI's award-winning PIQUA(TM) technology by adding new Quality of Service (QoS) insights that can be used to actively improve the user experience with VoIP and understand what is occurring on an individual connection-by-connection basis. Based on TI's DSP technology and embedded software, TI's PIQUA system provides a real-time distributed system of complete quality management elements designed to monitor and improve the quality of IP-based services, such as voice, data and video. The TNETV1051 also incorporates TI's new enhanced Acoustic Echo Canceller to eliminate unwanted echo and interference, providing yet another level of advanced voice quality.

The software architecture of the TNETV1051 is a common design for manufacturers' VoIP platforms, making it adaptable and easily integrated into a wide range of IP phones. TI's field-proven Telogy Software(TM) for VoIP allows customers the added benefit of customizing their applications to meet a variety of business needs. The flexibility enables manufacturers to more quickly develop products to best serve market requirements, while protecting their initial technology investment.

TI's TNETV1051 platform also incorporates the latest Power-over-Ethernet technology, which allows a phone to be powered directly from a standard Ethernet cable instead of an AC line. TI's TPS23750 power management integrated circuit combines a powered device and pulse-width-modulation (PWM) controller to safely and efficiently power the IP phone.


The TNETV1051 is currently sampling with full production expected in early 2007. A software development platform is also available. For more information on the TNETV1051 and TI's full portfolio of VoIP products, please visit ti.com/voip .
