SANTA CLARA, Calif. -- PMC-Sierra(TM), Inc. (Nasdaq: PMCS) today introduced the PM5385 ARROW 12xETEC, a 12 channel DS3/E3/STS-1E framing and mapping device for existing and next-generation Add/Drop Multiplexers (ADMs), Multi-service Provisioning Platforms (MSPPs), Digital Cross-Connects (DXCs) (see Figure 1) and terminal multiplexers (see Figure 2). With a measured power consumption of only 2.5W, the ARROW 12xETEC device offers a power savings of over 50 percent when compared to alternate solutions. Metro transport system designers can now leverage the ARROW 12xETEC's power efficiency to scale DS3/E3/STS-1E tributary line cards while lowering overall costs.

ARROW 12xETEC Offers High Performance DS3/E3/STS-1E Transport over SONET/SDH Networks

"With the ARROW 12xETEC, PMC-Sierra adds a high density DS3/E3/STS-1E mapping device to its broad portfolio of products optimized for the metro transport market," said Steve Perna, vice president and general manager, Service Provider Division at PMC-Sierra. "The ARROW 12xETEC's extensive feature set demonstrates PMC-Sierra's commitment to providing our transport customers with solutions addressing the global carriers' most stringent technical requirements."

The ARROW 12xETEC introduces several key features that are critical for metro transport equipment: fully digital DS3/E3 desynchronizers requiring no external Phase Locked Loops (PLLs); fast-locking DS3/E3 digital mechanisms for Automatic Protection Switching (APS); and bi-directional jitter attenuation, allowing use of lower cost Line Interface Units (LIUs). These key features enable system vendors to enhance system performance while significantly reducing their bill of materials and development costs. PMC-Sierra offers the industry's most complete line of transport equipment ASSPs including T1/E1, SONET/SDH and Ethernet over SONET/SDH (EoS) metro transport and access devices.
