2 May 2003, Santa Clara CA--PMC-Sierra has introduced the various devices which offer a complete physical layer solution for simultaneously aggregating, transporting and terminating OC-3/STM-1, OC-12/STM-4, and OC-48/STM-16 Packet-over-SONET (POS) and ATM traffic on a single line card.

The S/UNI MULTI devices ( PM5360 S/UNI(R) MULTI-48 and PM5354 S/UNI MULTI-2x12) are suited to use in physical interfaces to connect network elements that demand rapid bandwidth expansion like xDSL access multiplexors (DSLAMs), cable modem termination systems (CMTSs), and wireless base-station controllers to edge routers and multi-service switches.

A single multi-rate line card powered by one S/UNI MULTI-48 device, in conjunction with available multi-rate or pluggable optics modules, replaces up to three line card designs, addresses multiple applications and offers service providers unprecedented bandwidth scalability and network reliability.

"Marconi is utilizing PMC-Sierra's S/UNI MULTI-48 in its industry-leading capabilities of the BXR-48000 to help reduce costs and speed delivery of value-added services for service provider customers," said Dave Blakeney, vice president, engineering, for Marconi's Broadband Switching and Routing group.

"With the S/UNI MULTI-48, our BXR-48000 is better positioned to enable service providers to manage voice, video, and data traffic with greater efficiency,offering new differentiated IP services while continuing to leverage legacy revenue streams and reducing operating expenses."

When used with multi-rate optics, the S/UNI MULTI devices allow the deployment of a line card with field programmable line rates. As a result, simplified inventory management coupled with the ability to efficiently adapt ports to match bandwidth demand represents significant cost savings for service providers.

The S/UNI MULTI devices can also be used in SONET/SDH automatic protection switching (APS) architectures which meet the stringent requirements of quality of service (QoS) and service level agreements (SLAs) demanded by enterprise and business users.

Furthermore, both devices support channelisation of each SONET/SDH tributary down to the STS-3c level which enable carriers to offer additional services with the same line card.

"The S/UNI MULTI-48 and S/UNI MULTI-2x12 devices add to PMC-Sierra's already extensive line of S/UNI products and illustrates our commitment to offering optimized solutions for addressing today's challenging metro access markets," said Steve Perna, vice president and general manager of PMC-Sierra's Service Provider Division.

"Combining PMC-Sierra's proven technology with multi-rate capability in a highly integrated PHY/framer device offers system designers benefits which include minimizing design risk and effort as well as maximizing the reuse of hardware and software components."

The S/UNI MULTI-48 and S/UNI MULTI-2x12 maximize the ease of implementation and board space savings by combining multi-rate clock recovery and synthesis with the framing and mapping functions, replacing up to five discrete components.

With the software effort now reaching more than half of the total system development cost, leveraging a single design with the S/UNI MULTI devices across several line cards becomes increasingly important to OEMs.

The S/UNI MULTI devices include PMC-Sierra's standard compliant POS-PHY Level 3 (PL3) interface for POS traffic and provide UTOPIA Level 3 (UL3) interface for ATM traffic giving system designers access to a broad range of Layer 2 and 3 functions.

Samples of the PM5360 S/UNI MULTI-48 and PM5354 S/UNI MULTI-2x12 are available now and are priced at $378 and $228 in 1KU respectively. Both devices are pin-compatible, packaged in a 31 mm x 31 mm, 500 pin UBGA, rated for industrial temperature range operation (-40 to +85 degrees Celsius) and fabricated using low power, 0.18 micron CMOS process.
