Cisco ASR 900 Series Aggregation Services Routers
About the Cisco ASR 900 Series Aggregation Services Router
Cisco® ASR 900 Series Aggregation Services Routers are full-featured, modular aggregation platforms. They’re designed for the cost-effective delivery of converged mobile, residential, and business services. You get redundancy, a shallow depth, low power consumption, and high service scale in routers packed with useful features and optimized for small aggregation and remote point-of-presence (POP) applications.
The Cisco ASR 902 Router, Cisco ASR 903 Router, and Cisco ASR 907 Router provide a comprehensive and scalable feature set, supporting Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in compact designs.
Major Applications for the Cisco ASR 900 Series Aggregation Services Router
The modular Cisco ASR 900 Series router supports broadband aggregation for delivering “any-play” services (voice, video, data, and mobility). Designed to support thousands of subscribers, the ASR 900 Series includes quality of service (QoS) features that allow the routers to scale to a large number of queues per device. Combined with a highly granular, three-level hierarchical QoS algorithm, a large number of queues can result in a greatly enhanced broadband user experience. This full-featured Layer 2 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 architecture.
Preaggregation for Mobile Applications
Deployed as a preaggregation platform for mobile backhaul, the ASR 900 Series router can aggregate cell sites and use Multiprotocol Label Switching (MPLS) as a transport for Radio Access Network (RAN) backhaul traffic. It also provides the timing services required in today’s converged access networks by offering integrated support for the Building Integrated Timing Supply (BITS), 10 MHz, 1 Pulse Per Second (1PPS), and Time Of Day (TOD) interfaces. The router also supports synchronous Ethernet (SyncE) and IEEE-1588, and it can act as the source for network clocking for time-division multiplexing (TDM), Synchronous Digital Hierarchy (SDH), Synchronous Optical Network (SONET), Synchronous Ethernet (SyncE), and Global Positioning System (GPS) interfaces.
In addition, the ASR 900 Series router can be deployed in small and rugged environments, due to its shallow depth and qualification for extended temperature ranges.
Metro Ethernet Aggregation
The ASR 900 Series router is built to meet service provider requirements for Carrier Ethernet aggregation. It is optimized for remote central office and smaller aggregation sites where a full-featured, modular, small-footprint, and fully redundant aggregation platform is needed. This router offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.
