6/3/2003 - PMC-Sierra(TM), Inc. (Nasdaq:PMCS - News) introduced the PM5377 TSE(TM) 240 STS-1/AU-3 cross-connect capable of grooming up to 240 Gbit/s of SONET/SDH traffic.
The new TSE 240 cross-connect device integrates an unprecedented 96-ports of 2.5 Gbit/s serial technology and reduces the software complexity of automatic protection switching with innovative Message Assisted Protection Switching (MAPS(TM)) technology. As a result, the TSE 240 cross-connect reduces equipment costs for Add/Drop Multiplexers (ADM), Digital Cross-Connect Systems (DCS), and Multi-Service Provisioning Platforms (MSPP). The TSE 240 becomes the second cross-connect of the CHESS(TM) III family and joins the PM5376 TSE Nx160 STS-1/AU-3 cross-connect device, PM5326 ARROW 2x192, and PM5324 ARROW 1x192 SONET/SDH framers.
MAPS Reduces Protection Processing Complexity in Metro Equipment
SONET and SDH network architectures are highly resilient and are designed to rapidly recover from failures such as fiber cuts. Traditionally, Add/Drop Multiplexers or Multi-Service Provisioning Platforms implemented these protection mechanisms in complex software algorithms running on control processors. However, as network equipment scales and supports more data and fiber interfaces, software cannot process these algorithms fast enough to meet the required failure recovery times for SONET and SDH networks. The TSE-240 solves this problem with its MAPS technology by implementing the protection mechanisms in hardware. With failure recovery built into hardware, networking equipment can now scale without compromising reliability.
PMC-Sierra's Architectural Solution for Metro SONET/SDH Equipment
The 100 percent non-blocking TSE 240 cross-connect interfaces to PMC-Sierra's CHESS III SONET/SDH framers, Ethernet over SONET/SDH mappers and VT/TU pointer processors resulting in a time-to-market and system cost advantage for network equipment vendors. The TSE 240 integrates PMC-Sierra's proven high speed serial technology, Rate Agile Serial I/O (RASIO(TM)), at 2.5 Gbit/s and 622 Mbit/s link rates, to provide seamless line-card / backplane interconnection.
"Our state-of-the-art 2.5G I/O technology allows us to provide customers lower power and higher integration for 10G, 20G and 40G card rollouts. They are able to simply and cost-effectively upgrade currently deployed networking platforms and deliver new services required by carriers," said Steve Perna, vice president and general manager of PMC-Sierra's Service Provider Division. "The TSE 240 cross-connect's new hardware automatic protection switching mechanism which we call MAPS, enhances network reliability and will be utilized in our current and next generation CHESS products."
Pricing, Availability and Customer Support
The PM5377 TSE 240 non-blocking cross-connect is packaged in a 35mm x 35mm 1152 FCBGA using 0.13 micron CMOS technology. The device is priced at $1,375 in 1KU quantities and will be available in the third quarter of 2003.
