Cisco Route Switch Processor 3 - Control processor - plug-in module - for ASR 901, 901 10G, 902, 903, 920

Centralized network timing. Control plane and data plane elements. This Cisco Route Switch Processor (RSP) is the powerful centralized engine that provides these features and more for Cisco ASR 900 series routers. The ASR 900 RSP addresses the requirements of converged service provider networks, from Carrier Ethernet technologies to advanced services such as Multiprotocol Label Switching (MPLS), helping providers add advanced traffic management and intelligent packet-switching and routing features.

• Cisco Carrier Ethernet ASIC
  Powered by the Cisco Carrier Ethernet ASIC and designed specifically for the needs of service providers, ASR 900 series routers deliver essential Carrier Ethernet technologies. These include hierarchical quality of service (HQoS), MPLS, and Hierarchical Virtual Private LAN Services (HVPLS). The Cisco Carrier Ethernet ASIC provides line-rate performance and supports advanced services including access control list (ACL) and HQoS without affecting performance. The ASIC incorporates innovative traffic management capabilities while providing intelligent packet switching and routing operations.
• Service enhancement
  With ASR 900 series routers, each service is assigned enhanced QoS and security attributes. The routers provide advanced per-traffic-class metering and offer bidirectional packet-count and byte-count statistics. The service offering is enhanced with operations, administration, and maintenance (OAM) functionality that includes Layer 2 Connectivity Fault Management (CFM), IP service-level agreements (IP SLA) for Layer 3, and MPLS OAM.
• Clocking and timing services
  Cisco ASR 900 RSPs contain the central system clocking and timing functions for the ASR 900 series platform. With these crucial functions, required in a modern unified network, the RSPs offer integrated support for the Building Integrated Timing Supply (BITS) and Time Of Day (TOD) interfaces.
• High availability and modularity
  The ASR 900 series router is a fully modular platform. It delivers intrachassis hardware redundancy for all hardware components and supports software redundancy with In-Service Software Upgrade (ISSU) support when a pair of route switch processors is inserted in the Cisco ASR 903 router chassis. With two RSPs inserted in the Cisco ASR 903 router, one RSP operates in active mode, and the other RSP operates in hot standby mode. The Cisco ASR 900 RSP is a field replaceable unit (FRU), and it can be online inserted and removed (OIR) while the Cisco ASR 903 router system is operating.
• Management interfaces
  The Cisco ASR 900 RSP contains the out-of-band (OOB) management interfaces for the system. To offer flexible access to the router, a variety of interfaces are available for management access to the platform. They include a dual-mode console port that functions as either a USB console or a serial console port. In addition to the serial console access, the Cisco ASR 900 RSP contains an Ethernet management port that has no interaction with actual Carrier Ethernet ASIC traffic. In addition to the OOB control interfaces, an USB port can connect USB Flash devices for loading.
