SANTA CLARA, Calif. -- PMC-Sierra (NASDAQ: PMCS) today introduced the PM5337 ADM 622 and PM5338 ADM 622 PDH optical access devices for use in remotely deployed SONET/SDH Add/Drop Multiplexers (ADMs) and Terminal Multiplexers (see Figure 1). The highly integrated ADM 622 devices enable system designers to build robust, small footprint carrier-class equipment which extends legacy and next-generation services to small and mid-sized enterprises. As a result, networking OEMs can achieve a faster return on investment and meet time-to-market demands.

"The PMC-Sierra ADM 622 targets the access and metro-edge markets which will be the highest growth segments in the telecommunications carrier space over the next five years," said Steve Rago, principal analyst, networking and optical communications for iSuppli Corporation. "Telecommunications carriers are seeking value-added services they can offer to enterprises such as Ethernet Virtual LANs (VLANs). PMC-Sierra's ADM 622 supports such services. As market demand for Ethernet and PDH traffic grows, cost-effective switching of T1/E1 and virtually concatenated GFP traffic at VT/TU levels is critical for service providers."

"By integrating all the features necessary to build a complete ADM or Terminal Multiplexer in a single device, PMC-Sierra continues to drive down the cost of developing and deploying carrier-class equipment," said Greg Aasen, vice president and general manager, Service Provider Division at PMC-Sierra. "The ADM 622 product family facilitates the deployment of traditional PDH and new services like Ethernet while maintaining the standards of availability and reliability required by carriers."
