Legerity
and Clare Redefine Trunk Interface Linecard Market with
Best-in-Class FXO Evaluation Platform -
Industry's First Fully Software-Programmable FXO Evaluation Board
Can Be Easily AUSTIN,
TX and BEVERLY, MA - May 13, 2002 - Communication integrated
circuit suppliers Legerity, Inc., and Clare, Inc. today unveiled
a new foreign exchange office (FXO) evaluation platform that will
reduce the system-level cost, board space and development time
for trunk interface linecards used in enterprise, public network
and customer premises equipment (CPE) applications. The Legerity-Clare
FXO evaluation platform is the first board of its kind that can
be programmed through software to handle complex impedance synthesis
for virtually all world telecommunications markets. |

Jointly developed by Legerity and Clare, the FXO evaluation platform provides an integrated set of hardware and software tools that greatly simplifies the development of FXO linecards used in central office (CO), digital loop carrier (DLC), computer telephony, private branch exchange (PBX), IP-based PBX, router and telephony gateway equipment. With the evolution toward broadband networks, system designers increasingly rely on development tools to speed their trunk interface linecard applications to market. The FXO evaluation platform enables communication system designers to perform useful FXO functions immediately, including demonstration of a mini-PBX system. |
| "The
Legerity-Clare FXO evaluation platform will transform the trunk
interface linecard market by significantly streamlining the application
development process," said Julie Tyger, general manager of
Legerity's voice products. "The evaluation board represents
the first time that a DSP-based voice interface has been tightly
matched with a data access arrangement (DAA) in an easy-to-program,
solid state environment optimized for voice applications."
"Today's announcement means that communication equipment manufacturers are now able to jumpstart their trunk interface system designs with a best-in-class FXO linecard solution tailored to their application needs," said Steve Andrezyk, director of marketing for CPE products, Clare, Inc. "The combination of Legerity voice interface circuits and Clare DAAs provides a more elegant, cost-effective solution than FXO designs based on modem-oriented chipsets with limited AC termination settings or bulky isolation transformers with multiple discretes." The FXO evaluation board consists of Legerity's next-generation, four-channel QLSLAC codec/filter device on a motherboard with four sockets to accommodate phone line interface (PLI) daughtercards from Clare. Legerity's DSP-based QLSLAC device provides programmable codec and digital filter functions for each voice channel. Clare's PLI daughtercards support Loop Start and Ground Start operation, pulse dial operation, and regulatory surge protection. The FXO evaluation platform includes a daughtercard featuring the Clare LITELINK™ III DAA device, providing high-voltage electrical isolation for CPE applications. The Legerity-Clare FXO evaluation platform includes Legerity's WinSLAC™ software, which makes it easy to compute programmable filter coefficients and incorporate various impedances, and Legerity's VoicePath™ Script software, which allows the user to configure and control all aspects of the QLSLAC device. Using Legerity's application development software, system developers can quickly take their FXO designs to market. Pricing
