SANTA BARBARA, Calif. -- Occam Networks Inc. today introduced Ethernet Protection Switching (EPS) an Occam-developed technology that gives Ethernet the resiliency of SONET networks with a 50 msec fail-over to a backup path in case of link or node failure. With EPS, the Occam Broadband Loop Carrier (BLC) meets the "five nines" network availability required in public telecommunications networks, enabling carriers to take advantage of the cost savings and scalable bandwidth Ethernet provides. EPS is available with Occam's BLC System, a complete Ethernet- and IP-based loop carrier that combines the functionality of a DLC, DSLAM, and media gateway to deliver broadband data and lifeline POTS from a single, converged access network. "Reliability remains a key issue in deploying Ethernet in today's telecommunications network," said Mark Rumer, Occam co-founder and chief technology officer. "The Occam solution uses standard Ethernet silicon and switching combined with our Ethernet Protection Switching to make networks using Ethernet transport as resilient as SONET networks, while alleviating the ring size and distance limitations of SONET. With EPS, carriers can also leverage the high bandwidth and low cost of Ethernet in the access and metro networks without compromising their voice and data services." In a separate release:Occam Networks Inc. today introduced the second generation of its Broadband Loop Carrier System (BLC), a complete loop carrier solution that delivers ADSL and lifeline POTS services from a single, converged access network. The new system includes: the BLC 1200 Remote Terminal (RT), which integrates the functionality of a DLC, DSLAM, media gateway and copper/telephone line tester; the BLC 1240 Central Office Terminal (COT); and cabinets for outside plant deployment. Occam also announced support for integrated optical loop transport through Ethernet Protection Switching (EPS), an Occam-developed, standards-based technology that provides Ethernet transport with SONET-like reliability. "With today's tight capital budgets, carriers require the flexibility to deploy new services on an "as-needed" basis -- in a way that will allow them to gauge subscriber interest before investing large sums of money to rebuild their access networks," said Russ Sharer, vice president of marketing and sales for Occam. "Because of its small size and low cost, carriers can deploy the Occam BLC System to trial new broadband services with minimal capital outlay. The BLC System provides excellent flexibility in deploying new services without the operating costs associated with today's TDM-based access networks." Occam Networks Inc.
