SANTA CLARA, Calif. -- PMC-Sierra(TM), Inc. (Nasdaq:PMCS - News) today introduced the PM5329 ARROW 24xFE and PM5333 ARROW 8xFE 10/100 Ethernet over SONET/SDH mapping devices to enable the delivery of carrier class Metro Ethernet services. These new devices join PMC-Sierra's production released PM5397 ARROW 2xGE Gigabit Ethernet over SONET/SDH mapping device to offer complete 10, 100 and 1000 Mbit/s Ethernet transport services for Add/Drop Multiplexers (ADM) and Multi-Service Provisioning Platforms (MSPP).

PMC-Sierra's ARROW 24xFE and ARROW 8xFE products are the industry's first 622 Mbit/s and 2.5 Gbit/s capacity devices to support both low order (VT1.5/VC-12) and high order (STS-1, STS-3c/VC-4) Virtual Concatenation with hitless bandwidth adjustments using fully integrated LCAS processing. Fine granularity bandwidth tuning with low order Virtual Concatenation (1.6 Mbit/s VT1.5 / 2 Mbit/s VC-12) enables delivery of customer tailored 10/100 Ethernet services while maintaining network efficiency. For network efficient 1000 Mbit/s Ethernet services, PMC-Sierra's ARROW 2xGE device enables Gigabit Ethernet users to benefit from high order Virtual Concatenation and provide transport services from 50 Mbit/s all the way up to a full 1 Gbit/s with 50 Mbit/s (STS-1/VC-3) increments.

"PMC-Sierra is committed to driving and supporting emerging worldwide industry standard requirements for carrier class Ethernet solutions in Metro networks such as Virtual Concatenation and hitless LCAS," said Steve Perna, vice president and general manager of PMC-Sierra's Service Provider Division. "Our ARROW 24xFE and ARROW 8xFE products enable users to purchase Ethernet bandwidth in increments equivalent to familiar leased line T1/E1 rates while carriers can maintain and manage their SONET/SDH networks in the same manner as with their older, legacy services."

In a separate release:

PMC-Sierra(TM), Inc. (Nasdaq:PMCS - News) today 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) 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.

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."

In a separate release:

PMC-Sierra(TM), Inc. (Nasdaq:PMCS - News) today introduced the CHESS(TM) Wideband, a highly integrated solution for grooming up to 40 Gbit/s of T1/E1, T3/E3 and emerging Ethernet over SONET/SDH access services in metro transport networks.

The CHESS Wideband includes the PM5369 TUPP(TM) 9953, a 10 Gbit/s Tributary Unit Pointer Processor and the PM5370 WSE(TM) 40, a 40 Gbit/s capacity non-blocking VT/TU/STS/AU cross-connect. The CHESS Wideband VT/TU grooming solution provides cost-effective in-service upgrades to Multi-Service Provisioning Platforms (MSPP), sub-wavelength Digital Cross-Connect systems (DCS), and Add/Drop Multiplexers (ADM).

PMC-Sierra's CHESS Wideband products are well suited to provide both distributed and centralized VT/TU grooming. Traditionally, carriers have provided wideband switching at a large, centralized digital cross-connect in the core of the network. With the addition of a VT/TU server card to an existing STS/AU-based ADM, carriers can provide distributed VT/TU grooming at the edge of the network. The emerging generation of equipment providing distributed VT/TU grooming at the edge of the network offers a highly integrated, scalable solution that removes the need to backhaul all traffic to the core and as a result improves fiber efficiency and reduces equipment costs for carriers.

"Transport equipment vendors and service providers are working to preserve existing capital investment while providing new services like Ethernet through incremental upgrades to existing equipment," said Steve Perna, vice president and general manager of PMC-Sierra's Service Provider Division. "The CHESS Wideband addresses these requirements by enabling both new 10/100 Ethernet services and existing T1/E1 services to be cost-effectively managed at the VT/TU granularity."

The CHESS Wideband's TUPP 9953 Tributary Unit Pointer Processor device integrates performance monitoring and bit error rate technology with 10 Gbit/s capacity. The other CHESS Wideband device, the WSE 40, is a 100 percent non-blocking single chip VT/TU cross-connect solution that features Message Assisted Protection Switching (MAPS(TM)) technology. MAPS simplifies system software development by performing protection processing in hardware to meet service failure recovery times required by SONET and SDH standards. The TUPP 9953 and WSE 40 devices utilize PMC-Sierra's high speed serial technology, Rate Agile Serial I/O (RASIO(TM)), for seamless integration into the CHESS family of devices (see figure 3). The CHESS Wideband devices complement PMC-Sierra's CHESS III SONET/SDH family of products to provide a full grooming solution to support data rates from 1.5 Mbit/s to 10 Gbit/s.
