Xilinx and Paxonet Communications announce industry's first programmable STS-192 Sonet Solution

SANTA CLARA, Calif., July 25, 2002 -- At the Metro Optical Networking Forum today, Xilinx, Inc., (NASDAQ: XLNX) and Paxonet Communications, a Xilinx  AllianceCORE member and a leading telecommunications IP and Silicon provider, announced the immediate availability of the industry's first STS-192 SONET IP core package implemented on programmable logic. The solution entails complete STS-192 SONET Framing and Path Processing. The new cores, optimized for Xilinx Virtex-II and Virtex-II Pro FPGAs, offer the first validated non-ASIC solution for supporting full STS-192 SONET/SDH speeds on programmable logic devices. Target applications at the metropolitan edges of the network include Multi-Service Switches, Regenerators, Path Terminators, Add-Drop Multiplexers, Digital Cross Connects, Traffic Aggregators, and SONET Test Equipment.

"Extending Paxonet's SONET line of IP cores to encompass STS-192 provides our customers with fully flexible, customizable SONET solutions. The multi-gigabit serial I/O capability of Xilinx Virtex-II Pro devices is an ideal target for these cores, allowing customers to take full advantage of the combination while reducing their time to market," said Kevin Wayne Williams, vice president of Marketing at Paxonet.

"Paxonet's ability to provide a full range of SONET solutions on Xilinx FPGAs presents a flexible alternative to ASIC implementation, offering faster time-to-market," said Robert Bielby, senior director of Strategic Solutions at Xilinx. "We expect this solution to further our penetration into leading-edge metro-edge and core applications."

The new STS-192 IP Cores are compliant with ITU G707, G.783, BellCore GR253, and ANSI T1.105 standards and offer complete SONET Framing and Path Processing support, including:
aligning byte and frame on the incoming signal, inserting framing bytes (A1, A2) during transmissions,
maintaining B1 and B2 (BIP-1536) parity error counts in the receive section, computing BIP-8 parity as B1 byte and BIP-1536 parity as B2 bytes in the transmit section, and full processing of receive, transmit, and overhead pointers.

Availability

The STS-192 Kit, consisting of the STS-192 SONET Framer and the STS-192 Path Processor, is immediately available and will be showcased today in the Paxonet booth at the Metro Optical Networking Forum.
