Cisco uBR10012 OC-48
Dynamic Packet Transport Interface Module Set


The Cisco uBR10012 OC-48 Dynamic Packet Transport (DPT) Interface Module set is a high- performance, fault-tolerant interface set that provides unmatched connectivity options from the Cisco uBR10012 Universal Broadband Router to the IP core network. The Cisco uBR10012 OC48-DPT module set provides a powerful combination of service, scalability, and flexibility with the industry's broadest set of Layer 3 features.

This interface module set enables multiple system operators (MSOs) to substantially increase the data load over their optical transport infrastructure while lowering ongoing operational costs. The DPT feature set supports automatic network resiliency with fast cutover times that translate to a significant increase in overall network availability.

High-Speed Optical Interface

The Cisco OC-48 DPT interface module set for the Cisco uBR10012 is a high-capacity, high-performance interface that provides MSOs with an opportunity to use their existing fiber plant to realize a significant increase in bandwidth, coupled with industry-leading network resiliency and fault tolerance.

The innovative Cisco DPT solution is a Resilient Packet Ring (RPR) technology that combines the intelligence and scalability of IP routing with the bandwidth efficiencies of optical rings. Cisco DPT/RPR delivers simplified network operations, scalable IP services, and highly reliable IP-aware optical transport that translates to significant improvement in the ongoing cost of running today's high-speed networks.

The OC-48 DPT interface modules for the Cisco uBR10012 use an extensive and scalable set of Layer 3 features needed to deliver mission-critical commercial applications and delay-sensitive real-time applications such as voice and video over the cable IP infrastructure.

For example, operators have the ability to offer virtual private network (VPN) services via a comprehensive set of Multiprotocol Label Switching (MPLS) capabilities. Similarly, the OC-48 DPT product option complements the set of Cisco uBR10012 features needed to support the PacketCable standard.

The Cisco OC-48 DPT interface module set (see Figure 1) supports bandwidth up to 2.488 GBps and uses Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) framing with concatenated payloads over two counter-rotating rings. The two modules each terminate half of the OC-48 DPT ring. The two-module set may be placed in any two adjacent uplink slots in the Cisco uBR10012 chassis. Both modules are hot-swappable.

OC-48 DPT optics options support distances up to 2 km for short-reach optics, and up to 80 km for long-reach optics.

The Cisco uBR10012 OC-48 DPT implementation is fully compatible with implementations on platforms such as the Cisco 12000 Series, Cisco 7600 Series, and Cisco 10720 Series Internet routers.
