The Cisco ASR 9000 series Ethernet Line Cards are service-provider-focused Carrier Ethernet line cards from Cisco. These line cards deliver economical, scalable, highly available, line-rate Ethernet and IP/Multiprotocol Label Switching (MPLS) edge services. The Cisco ASR 9000 series Line Cards together with the Cisco ASR 9000 series platforms are designed to provide the fundamental infrastructure for scalable Carrier Ethernet and IP/MPLS networks, enabling profitable business, residential, and mobile services.The Cisco ASR 9000 series Ethernet Line Cards provide hierarchical QoS and simultaneous support for both Layer 2 and Layer 3 services and features, enabling operators to qualify and stock a single line card that can be deployed in any combination of Layer 2 and Layer 3 applications, thereby reducing capital expenditures (CapEx) and operating expenses (OpEx), as well as reducing the time required to develop and deploy new services. The Cisco ASR 9000 series Ethernet Line Cards set a high standard for service density, enabling operators to offer predicable, managed transport services while optimizing the use of network assets.With its synchronization circuitry and dedicated backplane timing traces for accessing the route switch processor's (RSP's) Stratum-3 subsystem, the Cisco ASR 9000 series Ethernet Line Cards provide standards-based line-interface functions for delivering and deriving transport-class network timing, enabling support of network-synchronized services and applications such as mobile backhaul and time-division multiplexing (TDM) migration. Recognizing that real-time media dominate next-generation services, Cisco has integrated media-monitoring technology into the Cisco ASR 9000 series Ethernet Line Cards. This multimedia technology enables real-time, monitoring and statistics collection of real-time video and voice flows, enabling proactive maintenance and management of today's media-rich services.
