SONET/SDH grooming switches target high-density access, metro equipment
May 4, 2005 Las Vegas, NV -- Vitesse Semiconductor has added to its line of SONET/SDH Time Slot Interchange (TSI) grooming switch devices for access and metro equipment. The company says its VSC9295 TSI is a flexible, scalable circuit switching platform for high-density SONET and mixed-traffic grooming.
"Our customers require a scalable architecture that can reach multi-Terabit capacities, and also scale down for more targeted solutions," maintains Juan Garza, circuit switch product marketing manager for Vitesse.
The company says its VSC9295 TSI switch addresses the compatibility and scalability requirements of OEMs and system designers by facilitating the upgrade of SONET/SDH equipment capacity, while maintaining compatibility with currently deployed infrastructure. The company says the device provides reliability and capacity up to 340 Gbit/sec with STS-1 granularity, while also supporting legacy backplanes and ASICs with 622-Mbit/sec interfaces.
According to the company, by utilizing TFI-5 and STS-12 interfaces, the device easily supports a range of existing line cards, backplanes, and ASIC infrastructures. The company says the device's integrated bit-slicing functionality reduces chip count and can lower the cost of fabric configurations up to 1.36 Tbit/sec; according to the company, the device's non-blocking, memory-based switch core also lowers costs while shortening development time by allowing single-step programming, eliminating the need for complex algorithms. The company says the device also lowers power requirements for SONET/SDH access and metro equipment by 25%.
For mid-range capacity SONET/SDH systems, the company has also introduced its pin-compatible VSC9292 170-Gbit/sec TSI, which the company says enables OEMs with flexibility in designing scalable architectures driven by system size and network traffic needs.
In volume quantities, the VSC9295 TSI (136-mm x 136-mm) is priced at $1,200 per unit. The VSC9292 TSI (68-mm x 68-mm) is priced at $850 per unit. The devices are available now.
