TI's DSP, Xcelis' Pantheon Enable Mobile Calls from Landline Handsets

6/10/2004 - Consumers will now be able to use landline handsets to place and receive calls over their cellular phones with a new device from Xcelis Communications, LLC. Texas Instruments Incorporated (TI) (NYSE:TXN) announced that Xcelis has implemented TI's TMS320C54CST digital signal processor (DSP), a fully-optimized telephony solution, on Pantheon, a mobile-landline integration device.

Pantheon attaches to any single line landline telephone and, in addition to placing and receiving landline telephone calls, uses Bluetooth® connectivity to route outgoing and incoming voice calls and data from users' mobile phones to traditional landline phones. For more information and a product demonstration of Pantheon, please see www.xcelis.com/pantheon.htm.

The C54CST is a flexible, low-power digital signal processor (DSP)-based solution optimized for remote data collection. Complete with SPIRIT Corp.'s optimized software, which consists of the most demanded telephony algorithms, the flexible CST framework allows the user to easily control those algorithms on different abstraction layers. It is ideal for customers developing remote data collection applications that integrate industrial control, voice functionality or other specialized functions using the peripherals of the DSP, such as telephony signaling. For example, Pantheon uses the DSP and optimized software to send data from a field location to a central location. By using the C54CST, Xcelis will be able to take Pantheon to market faster and with greater feature functionality than was previously available on the market. Likewise, by using Bluetooth, Pantheon eliminates the need to carry multiple handsets in the home and the hassle of using a cradle—an enormous advantage over the "call forwarding" and "cradle-based" solutions currently in the market.

"With an advanced feature set and robust SPIRIT algorithm support, the C54CST was the natural choice for the Pantheon product," said Glen Alexis, chief technology officer, Xcelis Communications. "We evaluated other architectures and DSPs from several other providers, and none came close to the functionality of the telecommunication algorithms in TI's chip.”

The TI C54CST is the industry's first DSP-based single-chip remote data collection application solution, and is flexible enough to function as a chipset controlled by a host processor or as a FLEX chipset, programmed to perform customer user functions that take advantage of the optimized ROM contents. Its 14 on-board algorithms from SPIRIT are compliant with eXpressDSPTM Software and Development Tools and capable of interfacing to industry-standard data access arrangement (DAA), and include four data, four telephony and six voice algorithms.

In addition to the C54CST, Pantheon uses other TI logic devices including the TPS78633, eXpressDSP-compliant algorithms in ROM and CSL and LIO standards for the UART, DAA and McBSP device drivers.
