The Cisco ASR 920 Router helps service providers deliver differentiated, cost-effective advanced services such as residential broadband, mobile, and Metro Ethernet based on a variety of features. The Router offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced L2VPN, 元VPN, and multicast services. It is optimized for remote access and central offices for smaller aggregation sites where a full-featured, small-footprint converged platform is needed. The Cisco ASR 920 Router is built to meet service provider requirements for Carrier Ethernet access. In addition to the timing services, the Cisco ASR 920 Router can be deployed in small and fully sealed cabinets in outside environments because of its small form factor and durability in extended temperature ranges. The Cisco ASR 920 Router also supports Synchronous Ethernet (SyncE) and IEEE-1588 and can act as the source for network clocking for time-division multiplexing (TDM), SDH and SONET, and SyncE interfaces. It provides the timing services required in today’s converged access networks by offering integrated support for the Building Integrated Timing Supply (BITS), 1 Pulse Per Second (1PPS), and Time Of Day (TOD) interfaces. 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.ĭeployed 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. The large number of queues, combined with the three-level hierarchical QoS algorithm, results in an enhanced broadband user experience. 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 Router capable of scaling up to a large number of queues per device.
Asr920 series#
Cisco ASR 920 Series (part number ASR-920-12CZ-A).The Cisco ASR 920 Series has multiple models with different port densities, including the following models that feature lower port densities:
An optional "pay-as-you-grow" feature and service activation model makes the Cisco ASR 920 Series flexible and cost-effective. 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). It also enables service providers to deploy Multiprotocol Label Switching (MPLS)-based VPN services from within the access layer. The Cisco ASR 920 Router provides a comprehensive and scalable feature set of Layer 2 VPN (L2VPN) and Layer 3 VPN (元VPN) services in a compact package. These temperature hardened, high-throughput, small form factor, low-power-consumption routers are optimized for mobile backhaul and business applications. 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.
