PMC ATM/POS-PHY

BURNABY, British Columbia -- PMC-Sierra (NASDAQ: PMCS) today announced the latest addition to the industry's most comprehensive ATM/POS-PHY product line; the PM5384 S/UNI(R)-1x155, a single channel OC-3c SONET/SDH-PHY for ATM/POS with industry standard UTOPIA Level 2 and POS-PHY Level 2 system interfaces. The continued growth in Internet access bandwidth is driving service provider upgrades to metro networks to support greater capacity. To facilitate this expansion, system vendors require highly integrated, fully standards compliant, off-the-shelf silicon solutions to enable the rapid migration of DS-3 to OC-3 access links. To meet these needs, the S/UNI-1x155 occupies the industry's smallest board area, while providing the most integrated functionality and full standards compliance. Where current solutions require two devices to support ATM or POS, the S/UNI-1x155 incorporates both and allows selectability in a single design. All of this improves system design flexibility, prov ides time-to-market advantages, and reduces overall system power and cost for Packet-over-SONET (POS) and ATM-based networking equipment.
