Cisco OSM-1OC48-POS-SS+ : Enhanced 1-port OC-48/STM-16 SONET/SDH OSM, SM-SR, w/ 4 GE

Achieving network consolidation is particularly challenging at network aggregation points. The devices at these points must be able to deliver multiple Layer 2 and Layer 3 services, while providing efficient transfer of network traffic from customer access nodes to the core network and back. These aggregation devices must simultaneously provide scalable bandwidth and interface density between the access and core networks; support numerous network protocols, as well as quality-of-service (QoS), security, and accounting features; and be compatible with the existing SONET infrastructure.
Cisco® 7600 Series routers provide the performance, density, and features needed for network aggregation devices in consolidated network architectures. To provide aggregation services over an existing SONET infrastructure, Cisco Series routers can be configured to support various SONET interface cards, such as the Cisco 1-port OC-48c/STM-16 Packet over SONET (POS) enhanced optical services modules (OSMs). These enhanced OSMs deliver advanced IP and Multiprotocol Label Switching (MPLS) services based on the Cisco Parallel Express Forwarding (PXF) network processor. The 1-port OC-48c POS includes two PXF processors-one for transmit processes and the other for receive processes.
