Major Applications Broadband Aggregation 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. Major Differentiators The ASR 900 Series router helps service providers deliver advanced services for residential broadband, mobile, and Metro Ethernet applications. This allows an operator to provide differentiated and cost-effective services to end users. Flexible Deployment Options The ASR 900 Series router is designed with a compact form factor to accommodate deployment in small spaces. Available with a range of mounting options, the router can be deployed in space-constrained locations such as ETSI 300-mm deep cabinets. The side-to-side airflow design allows two Cisco ASR 900 Series routers to be mounted back-to-back in a 600-mm cabinet, while the extended temperature range supported by the router allows it to be deployed in locations with minimum environmental control. Small footprint and extended temperature range support allow service providers to extend the reach of their Carrier Ethernet networks to more challenging and remote locations, yet save money on air conditioning. |
