Cisco 10000 Series OC-48c/STM-16 Packet
over SONET/SDH Line CardThe Cisco 10000 Series OC-48c/STM-16 Packet over SONET/SDH Line Card is a high-performance interface that provides superior connectivity options from the Cisco 10000 Series to the core network. Packet over SONET/SDH (POS) enables Internet service providers (ISPs) to substantially increase the data load over their optical transport infrastructure. With its line-rate OC-48c/STM-16 capacity (2.488 Gbps), the Cisco 10000 Series OC-48c/STM-16 POS Line Card provides a powerful combination of service, scalability, and flexibility with the industry's broadest set of Layer 3 features (Figure 1).

This interface line card enables ISPs to substantially increase the data load over their optical transport infrastructure while lowering ongoing operational costs. It also supports POS high-availability technology ideally suited for Internet and IP networks.
Product Description
The Cisco 10000 Series OC-48c/STM-16 POS Line Card is a high-capacity, high-performance interface that provides ISPs 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. This increased interface capacity enables ISPs to provide new levels of cost-effective IP services to their expanding customer base by more efficiently using existing resources.
The Cisco 10000 Series OC-48c/STM-16 POS Line Card supports OC-48c/STM-16 bandwidth of 2.488 Gbps of POS traffic. The full-height line card may be used in any line-card slot in the Cisco 10000 Series chassis. The OC-48c/STM-16 POS line card is a standard implementation of POS. It supports advanced features such as SONET automatic protection switching (APS), SDH multiplex section protection (MSP), alarm processing, and performance monitoring, and is fully compatible with standards-based POS implementations on platforms, including the Cisco 12000 Series and the Cisco 7600 Series. Note that the hardware is Spatial Reuse Protocol (SRP) ready, but SRP functions are currently not supported on the platform.
Key Benefits
Efficient, High-Performance Bandwidth Utilization
The Cisco 10000 Series OC-48c/STM-16 POS Line Card provides the unique advantages of efficient bandwidth utilization combined with very high performance. An OC-48c/STM-16 line-rate performance of 2.488 Gbps provides the increased bandwidth required by many ISPs to handle the most demanding user requirements such as faster access to Web pages and data-intensive applications such as real-time video and large file transfers.
The OC-48c/STM-16 POS line card provides more than just a "fat pipe." The OC-48c/STM-16 POS line card uses 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, ISPs can offer virtual-private-network (VPN) services through a comprehensive set of Multiprotocol Label Switching (MPLS) capabilities.
Fault-Tolerant Backbone Connectivity
The Cisco 10000 Series OC-48c/STM-16 POS Line Card implements SONET APS, a valuable tool to support network resiliency, fault tolerance, and increased overall network availability. APS provides a very fast Layer 1 mechanism to support 1:1 redundant transmission circuits between SONET devices. APS allows rapid switchover from one fiber connection to another in the event of a fiber cut, module failure, signal failure, or signal degradation. The result is increased network resiliency, minimal loss of data, and reduction in time-consuming reroutes of data.
Optimized for IP-Based Differentiated Services
The Cisco POS solution is optimized to support Internet-based multiservice networks based on IP. The Cisco POS implementation places the IP layer directly above the SONET layer and eliminates the overhead needed to run IP over ATM over SONET for multiservice applications. The performance capacity of the Cisco 10000 enables service providers to provide customers guaranteed and Differentiated Services (DiffServ) through IP-based quality-of-service (QoS) products for their multiservice applications. With the three precedence bits in the IP header, it is possible to provide differentiated classes of service (CoSs) by using Random Early Detection (RED) and Weighted RED (WRED) to support multiservice applications, including data, voice, and video applications.
Compatibility and Interoperability Reduces Costs
POS protects the customer's investment by providing a new high-performance backbone connection that optimizes existing fiber in the network while remaining compatible with the existing equipment in the network. The Cisco 10000 Series OC-48/STM-16 POS Line Card is fully compatible with existing OC-48/STM-16 POS implementations in the network. By enabling customers to more efficiently use existing fiber and reuse currently installed platforms, the Cisco 10000 Series POS implementation saves the customer money and improves the overall efficiency of the network.
