Cisco ASR 920 Series Aggregation Services Routers: Passively Cooled Model Data Sheet
Available Languages
The Cisco® ASR 920 Series Aggregation Services Router (ASR) is a full-featured converged access platform designed for the cost-effective delivery of wireline and wireless services. These temperature-hardened, high-throughput, shallow-depth, low‑power-consumption routers are optimized for mobile backhaul and business applications. The Cisco ASR 920 provides a comprehensive and scalable feature set of Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in a compact package. It also enables service providers to deploy Multiprotocol Label Switching (MPLS)-based VPN services from within the access layer. The Cisco ASR 920 Series offers key Carrier Ethernet features that simplify network operation; you can use them for premium services with enhanced service-level agreements (SLAs). An optional "pay-as-you-grow" feature and service activation model makes the Cisco ASR 920 Series a flexible and cost-effective solution.
This data sheet features the Passively Cooled Cisco ASR 920 Series Router model (part number
ASR-920-10SZ-PD).
Major Applications
Broadband Access
The Cisco ASR 920 Router supports broadband access for delivering “any-play” services (voice, video, data, and mobility) to thousands of subscribers, with quality of service (QoS) on the Cisco ASR 920 capable of scaling up to a large number of queues per device. The large number of queues, combined with the three-level hierarchical QoS algorithm, results in an enhanced broadband user experience. This full-featured Layer 2 switch and Layer 3 router supports a variety of broadband applications including IPTV and video on demand (VoD), enhancing and extending the Cisco Evolved Programmable Network (EPN) architecture.
Converged Access for Mobile Applications
Deployed as a converged access platform for mobile backhaul, the Cisco ASR 920 Router can aggregate multiple base stations through multiple Ethernet and IP interfaces and can use MPLS as a transport for mobile backhaul traffic. It provides the Synchronous Ethernet (SyncE) and IEEE-1588 timing services required in today’s converged access networks. The router can be deployed in outside environments inside a rain- and water-protected cabinet and is certified for extended temperature ranges.
Metro Ethernet Access
The Cisco ASR 920 Router is built to meet service provider requirements for Carrier Ethernet access. It is optimized for remote access and central offices for smaller aggregation sites where a full-featured, small-footprint converged platform is needed. The router offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.
Major Differentiators
The Cisco ASR 920 Router helps service providers deliver differentiated, cost-effective services such as Residential Broadband, Mobile, and Metro Ethernet.
Flexible Deployment Options
The Cisco ASR 920 passively cooled version supports deployment in rain- and water-protected cabinets for outdoor deployment in line with GR-3108 Class 3 Installation and supports both horizontal and vertical mounting options.
The extended temperature range supported by the Cisco ASR 920 Router allows the router to be deployed in locations with minimal environmental control. The passively cooled unit with support for an extended temperature range allows service providers to extend the reach of their Carrier Ethernet networks to more rugged and remote locations.
Power Supply Unit: High Availability
This router supports dual DC power supplies. They are redundant and built into the chassis. The Ethernet interfaces are available in copper and fiber, with speeds ranging from 10 Mbps to 10 Gbps.
Powered by the Cisco Carrier Ethernet ASIC
Powered by the Cisco Carrier Ethernet application-specific integrated circuit (ASIC), which was designed specifically for service providers, the Cisco ASR 920 Series delivers essential Carrier Ethernet technologies, including hierarchical quality of service (HQoS), MPLS, and Virtual Private LAN Services (VPLS). This custom and advanced ASIC design provides uninterrupted line-rate performance while delivering complex and taxing services such as access control list (ACL) and HQoS. The Carrier Ethernet ASIC integrates Cisco traffic management innovation to deliver intelligent packet switching and routing operations.
Service Enhancement
In the Cisco ASR 920 Router, each service is assigned enhanced QoS and security attributes. The router provides advanced per-traffic-class metering and offers bidirectional packet-count and byte-count statistics. The service offering is enhanced with operations, administration, and maintenance (OAM) functions including Layer 2 Connectivity Fault Management (CFM), IP service-level agreement (SLA) for Layer 3, and MPLS OAM.
Benefits
MPLS in the Access layer
The Cisco ASR 920 Series extends MPLS into the access layer by allowing service providers to initiate MPLS-based Layer 2 and Layer 3 VPN services from within the access layer. The router gives service providers the ability to expand MPLS toward their network edge to gain the advantages of a single unified MPLS control plane across their networks. It offers full VPLS support allowing multipoint services definition. For additional flexibility, VPLS can be deployed as a full mesh or as Hierarchical VPNS (H-VPLS).
Pay-as-You-Grow Investment Model
The return on investment (ROI) on an access element is heavily influenced by its location in the network and proximity to customers. The ability to deploy the Cisco ASR 920 Series and later activate features on demand delivers investment protection. This protection allows flexible timing for deploying MPLS and10-Gigabit Ethernet services and boosting service capacity.
Advanced Service-Level Agreements
Service-aware QoS allows service providers to expand and differentiate their services portfolio with highly advanced and differentiating SLAs. The HQoS capabilities of the Cisco ASR 920 Series scale to eight queues per service, three levels of scheduling, and buffer volumes capable of accommodating today's most demanding wireline and wireless applications.
Mobile Timing and Synchronization Services
The Cisco ASR 920 Series provides the timing services required in a converged access network to support mobile solutions including Radio Access Network (RAN) applications. The router supports SyncE with Ethernet Synchronization Messaging Channel (ESMC) and Synchronization Status Messages (SSM) to allow excellent clock-source traceability. The Cisco ASR 920 Series supports IEEE-1588 as well.
Operational Efficiency for Carrier Ethernet Access Deployments
The Cisco ASR 920 Series features major enhancements that help service providers simplify and facilitate the management of their networks, resulting in diminishing operational costs. This innovative feature set allows the Cisco ASR 920 Series to be deployed in a variety of applications including business service with 10-Gigabit Ethernet User Network Interface (UNI) and Ethernet mobile backhaul. These features enhance performance awareness, facilitate troubleshooting, and simplify service turn-up and restoration, ultimately reducing operational costs. "Dying gasp" for power indicators and four external alarm inputs to detect changes in remote sites further help service providers manage the health of network elements.
Universal Customer Premises Equipment
With all interfaces built in, this fixed-form-factor platform is versatile and can cover many deployment scenarios including Gigabit Ethernet and 10-Gigabit Ethernet deployments. The licensing mechanism supports enabling additional 1-Gigabit/10-Gigabit Ethernet interfaces as required for a particular deployment, allowing service providers to customize the configuration of the device and pay only when their services grow. With support for extended temperatures, this router can be deployed in protected outside environments and remote locations.
Software
The Cisco ASR 920 Series Routers are supported in Cisco IOS® XE Software, which is a modular operating system. Cisco IOS XE Software is designed to provide modular packaging, feature velocity, and powerful resiliency. For more information on the supported features and software capabilities, see the Cisco IOS XE Software for Cisco ASR 920 Series Aggregation Services Router data sheet.
