The Cisco 12000 Series 4-Port OC-12c/STM-4c DPT ISE Line Card further extends Cisco Systems leadership in RPR networking. This line card combines the bandwidth efficiencies and rich service capabilities of IP routing with the bandwidth-rich, Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH)-like, self-healing capabilities of RPRs to deliver fundamental cost and functionality advantages over traditional networking solutions.
Service providers face the challenge of meeting customer demand by building scalable, feature-rich networks that can deliver value-added services such as MPLS virtual private networks (VPNs), voice, video, and data integration, and tiered service offerings without compromising density or line-rate performance. The Cisco 12000 Series 4-Port OC-12c/STM-4c DPT ISE Line Card terminates two OC-12c/STM-4c RPR rings and provides an extensive set of service-enabling edge features while performing at line rate simultaneously on all ports.
