CAMARILLO, Calif. -- Vitesse Semiconductor Corp. (NASDAQ:VTSS - News) today announced two new additions to its industry-leading SONET/SDH Time Slot Interchange (TSI) grooming switch family: the VSC9190, 50 Gbps TSI Switch, and the VSC9191, 100 Gbps TSI Switch. Both devices are targeted at dramatically reducing power and complexity of SONET grooming applications, while simultaneously simplifying and accelerating the system level design process. These devices reduce power requirements by more than 50% over comparable solutions, and, by incorporating automatic protection switching and rate aggregation into a single device, reduce board chip count by a factor of five, dramatically shrinking space requirements and lowering costs.

TSIs are a key building block in the $7 billion optical transport systems market. This market grew by 11% in 2004 and is forecasted to grow another 6% in 2005, as reported by the Dell'Oro Group. TSIs perform the necessary function of deskewing, switching, and regenerating SONET/SDH signals at the STS-1/STM-0 level. The VSC9190 and VSC9191 address these complex requirements within Access and Metro equipment such as SONET/SDH Multiservice Switches, Add Drop Multiplexers, Optical Switches, and DWDM Long Haul and Metro equipment.

These scalable TSIs support dual rate 2.5 Gbps or 622 Mbps Input/Output (I/O) speeds, enabling high-speed 2.5 G links or compatibility with existing 622 M equipment, and contributing to lower cost and power requirements. Their fully non-blocking memory-based switch core simplifies system architectures and shortens overall development time with fast, single-step programming that eliminates the need for complex programming algorithms.

The VSC9190 and VSC9191 utilize bit-slicing technology to enable fabric configurations up to 1.36 Tbps using the lowest possible chip count. This functionality routes traffic to and from scalable hubs based on Vitesse's flagship VSC9295 340 Gbps single-chip TSI. The devices also use 2.5 Gbps TFI-5 and 622 Mbps STS-12/STM-4 standards-based interfaces for connecting with existing line cards, backplanes, and ASIC infrastructure.

"SONET isn't dead," says Juan Garza, circuit switch product marketing manager for Vitesse. "The VSC9190 and VSC9191 are designed to enable OEMs to dispel the myth that SONET switching equipment is expensive and difficult to build. Over a decade of industry-leading expertise is built into every chip, allowing the system designer to focus their resources on other tasks to get their product to market faster without the compliance and interoperability issues of home brewed alternatives."
