Vitesse Delivers Second Generation of SONET/ SDH Grooming Products; Complete SONET/SDH Chipset Solution Supports Grooming of TDM Signals From the Optical Core to the Metro Edge.Business Editors & High-Tech Industry Writers CAMARILLO, Calif.--(BUSINESS WIRE)--Aug. 20, 2001 Vitesse Semiconductor Corp. (Nasdaq:VTSS VTSS Vehicle Theft Security System VTSS Vancouver Technical Secondary School ) today introduced the next generation of products in the TimeStream(TM) family of SONET/SDH switch fabric and line card devices. TimeStream products enable increased density of OC-48 and OC-192 interfaces, allow implementation of 2.5Gb/s backplane connectivity, provide support for VT1.5 grooming, deliver higher density STS-1/STM-1 grooming and enable future support for OC-768. Support for grooming at both the VT1.5/TU-12 and STS-1/STM-1 is crucial in the metropolitan environment. Core and metro networks Metro Networks is a broadcasting outsourcing company based in Houston, Texas. It is a subsidiary of Westwood One, which is managed by CBS Radio. The company operates a number of local and regional news and traffic facilities that provide regular reports to affiliates, together with are groomed down to the STS-1/STM-1 level, providing bandwidth for connections from DS-3/E3 to OC-192c. However, the metro edge continues to be influenced by the need to groom at both the STS-1/STM-1 and VT1.5/TU-12 level, reflecting the tremendous momentum of leased line A private communications channel leased from a common carrier. Most digital lines require four wires (two pairs) for full-duplex transmission. (communications, networking) leased line voice, T1s and frame relay A high-speed packet switching protocol used in wide area networks (WANs). Providing a granular service of up to DS3 speed (45 Mbps), it has become popular for LAN to LAN connections across remote distances, and services are offered by most major carriers. connections. The TimeStream product family addresses the needs of the all optical transport applications in the network such as next generation SONET/SDH ADMs at the optical edge, Multiservice Provisioning Platforms (MSPPs) in metro environments, and high density STS-1/STM-1 based optical crossconnects in the core. TimeStream provides an end-to-end solution (jargon) end-to-end solution - (E2ES) A term that suggests that the supplier of an application program or system will provide all the hardware and/or software components and resouces to meet the customer's requirement and no other supplier need be involved. Compare: turn-key solution. for terminating OC-3 to OC-192 optical interfaces and grooming the traffic to the customer required granularity. Combining the TimeStream product family with other Vitesse switching solutions, such as GigaStream(TM) packet/cell switch fabrics, allows vendors to construct equipment capable of switching and routing optical, SONET/SDH, IP, ATM, and Ethernet traffic in applications ranging from the optical edge to the core network. All TimeStream components include backplane clock and data recovery circuitry ensuring a 'glueless' interface between devices. Backplane protocols utilize SONET/SDH conventions and not proprietary formats, allowing customers to easily integrate Vitesse components with existing hardware architectures. Features unique to the TimeStream family allow modification of bytes on the backplane for in-band communication and extensive on-board performance telemetry telemetry Highly automated communications process by which data are collected from instruments located at remote or inaccessible points and transmitted to receiving equipment for measurement, monitoring, display, and recording. processing, thus simplifying the design of the control software. This generation of Vitesse components also includes hardware-based protection switching, allowing vendors to construct equipment that can recover from fibre cuts or equipment failures within the guidelines of Telcordia GR-1400, the standard demanded by RBOCs and CLECs alike. Typically, system software is required to detect fibre cuts and optical failures and make protection decisions to heal the network. The new TimeStream switch components automatically detect failures and restore the network within a millisecond One thousandth of a second. See space/time and ohnosecond. (unit) millisecond - (ms) One thousandth of a second, one thousand microseconds. A long time for a modern computer. . System designs constructed with competing solutions are limited by performance of software for protection switching. Hardware-based protection switching is the only way customers can continue to meet sub-millisecond protection switching requirements as the number of optical ports continues to grow. "Features, such as integrated 2.5Gb/s backplanes, extensive performance monitoring, hardware-based protection switching, and true non-blocking TSI TSI Total Solar Irradiance (sum solar light in energy per unit of time) TSI Trading Standards Institute (UK) TSI Transportation Safety Institute (US DOT) architectures anticipate and solve our customers' difficult system level issues. These features enable new system configurations and accelerate our customers' time to market, but most importantly allow our devices to co-exist with ASICs within existing customers' systems that are shipping in volume," said Andrew Schmitt, Vitesse's SONET/SDH product line manager.
