Major Applications

Broadband Access

Cisco ASR 920 routers assistance broadband access for carrying «any-play» services (that is, voice, video, data, and also mobility) to thousands of subscribers. High quality of organization (QoS) on this routers can scale as much as a huge number that queues every device. This large number that queues, combined with a three-level hierarchical QoS algorithm, can provide an enhanced broadband user experience. This full-featured layer 2 switch and Layer 3 router support a selection of broadband applications, including IPTV and video clip on need (VoD), enhancing and also extending the Cisco progressed Programmable Network (EPN) architecture.

Converged access for cell phone Applications

Deployed as a converged accessibility platform because that mobile backhaul, the ASR 920 router can accumulation multiple base stations v multiple Ethernet and also IP interfaces, and it have the right to use MPLS as a move for mobile backhaul traffic. It likewise provides the Synchronous Ethernet (SyncE) and IEEE-1588 timing services compelled in today’s converged access networks. The version (ASR-920-12SZ-IM/ASR-920-12SZ-IM-CC) has a integrated GNSS receiver, which deserve to act as a grandmaster clock because that aggregating and also backhauling tiny cell traffic. It also supports Cisco global Power over Ethernet (Cisco UPOE®) technology, which deserve to be offered to power small cell radios. The router deserve to be deployed in small, totally sealed cabinets in outside environments, because of the small type factor and also its durability in prolonged temperature ranges.

Advanced Security

Small cells deployments face obstacles on the defense front due to their location. The version (ASR-920-12SZ-IM/ASR-920-12SZ-IM-CC) support security company such as IP protection (IPSec) to aid protect against vulnerabilities come subscriber traffic and the network. A built-in hardware crypto engine allows the feature to scale and makes it ideal for extensive tiny cell deployments.

Metro Ethernet Access

The Cisco ASR 920 router is developed to meet service provider requirements for carrier Ethernet access. It is optimized because that remote access and main offices, for smaller sized aggregation sites where a full-featured, small-footprint converged communication is needed. The router offers company flexibility and also delivers class 2, IP, and also MPLS transfer for advanced L2VPN, L3VPN, and multicast services.

Major Differentiators

ASR 920 routers assist service providers provide differentiated, cost-effective solutions such together residential broadband, mobile, and Metro Ethernet.

Flexible Deployment Options

ASR 920 routers are designed v a 1RU compact type factor come accommodate deployment in little spaces. ASR-920-24SZ-IM model is 1.5RU to accommodate the user interface module in the chassis. Obtainable with a variety of mounting options, this routers have the right to be deployed in space-constrained locations and also cabinets. The prolonged temperature range supported through ASR 920 router permits them to it is in deployed in locations with minimal eco-friendly control. In addition, their small footprint allows service service providers to extend the with of your Carrier Ethernet networks come more an overwhelming and remote locations.

Power-Supply Unit: High Availability

ASR 920 routers market a an option of AC and DC power supplies, which space redundant and also built right into the chassis. Ethernet interfaces are obtainable in copper and also fiber, with speeds varying from 10 Mbps come 10 Gbps. The time-division multiplexing (TDM) interfaces are available in the product models (ASR-920-12SZ-IM, ASR-920-12SZ-IM-CC and ASR-920-24SZ-IM), v speeds ranging from n x DS-0 come OC-12/STM-4 because that plesiochronous digital hierarchy (PDH), SDH, and SONET. The user interface modules, strength supplies, and also fan tray room all field-replaceable.

Powered by the Cisco carrier Ethernet ASIC

Powered by the Cisco transport Ethernet application-specific combined circuit (ASIC), which was designed particularly for organization providers, ASR 920 routers deliver essential carrier Ethernet technologies, including hierarchical quality of business (HQoS), MPLS, and also Virtual private LAN services (VPLS). This tradition and progressed ASIC architecture provides uninterrupted line-rate performance while delivering facility services such as access control perform (ACL) and also HqoS. The transport Ethernet ASIC integrates Cisco traffic-management development to provide intelligent packet-switching and routing operations.

Service Enhancement

In ASR 920 routers, each business is assigned intensified QoS and also security attributes. The router provides progressed per-traffic-class metering and also offers bidirectional packet-count and byte-count statistics. The business offering is intensified with operations, administration, and also maintenance (OAM) attributes that encompass Layer 2 Connectivity Fault management (CFM), IP service-level agreements (SLAs) because that Layer 3, and MPLS OAM.


MPLS in the access Layer

Cisco ASR 920 routers expand MPLS right into the accessibility layer by enabling service suppliers to start MPLS-based layer 2 and also Layer 3 VPN services from in ~ the accessibility layer. These routers give service providers the capability to broaden MPLS toward their network leaf to get the benefits of a single unified MPLS control plane across their networks. Castle offer complete VPLS support, enabling multipoint services definition. For additional flexibility, VPLS deserve to be deployed as a full mesh or as hierarchical VPLS (H-VPLS).

Incremental invest Model

The return on invest (ROI) ~ above an access element is heavily influenced by its location in the network and also proximity come customers. The ability to deploy ASR 920 routers, climate activate features later, top top demand, delivers invest protection. This protection enables flexible timing for deploying MPLS and10 Gigabit Ethernet solutions and boosting service capacity.

Advanced Service-Level Agreements

Service-aware QoS permits service suppliers to expand and also differentiate their services portfolio v highly advanced and identified SLAs. The HQoS capabilities of ASR 920 routers range to eight queues every service, three levels of scheduling, and buffer volumes qualified of accommodating today’s many demanding wireline and wireless applications.

Mobile Timing and Synchronization Services

ASR 920 routers administer the timing services compelled in a converged accessibility network to support mobile solutions, consisting of Radio accessibility Network (RAN) applications. They additionally support SyncE v Ethernet Synchronization messaging Channel (ESMC) and also Synchronization status Messages (SSM) to allow excellent clock-source traceability. In addition, the routers support IEEE-1588, and the ASR-920-12SZ-IM/ASR-920-12SZ-IM-CC model has a built-in GNSS recipient which can act as a grandmaster clock because that aggregating and also backhauling tiny cell traffic.

Operational efficiency for carrier Ethernet access Deployments

Cisco ASR 920 routers feature significant enhancements that aid service suppliers simplify and facilitate network management, for diminished operational costs. V these put in order features, ASR 920 routers have the right to be deployed in a range of applications, including organization services with 10-Gigabit Ethernet User Network user interface (UNI) and also Ethernet mobile backhaul. The attributes enhance power awareness, facilitate troubleshooting, and simplify company turn-up and restoration.»Dying gasp» for power indicators and also four exterior alarm inputs likewise detect changes in remote sites, giving organization providers additional tools to control the health and wellness of network elements.

Universal customer Premises Equipment
