Маршрутизаторы Cisco ASR серии 900
The Cisco ASR 900 Series is a modular aggregation platform that delivers cost-effective 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.
Features and Capabilities
Deliver a greatly enhanced broadband customer experience with the modular Cisco ASR 900 Series router. This full-featured Layer 2 and Layer 3 switch router supports broadband aggregation for delivering "any-play" services (voice, video, data, and mobility). You can offer a variety of broadband applications, including IPTV and video on demand (VoD).
Designed to support thousands of subscribers, quality of service (QoS) on the Cisco ASR 900 Series router scales up to a large number of queues per device. Large queue support, combined with a highly granular QoS algorithm (three-level hierarchical QoS), helps you give your customers a great experience.
Pre-Aggregation for Mobile Applications
Deployed as a pre-aggregation platform for mobile backhaul, the Cisco ASR 900 Series router can aggregate cell sites and use Multiprotocol Label Switching (MPLS) as a transport for Radio Access Network (RAN) backhaul traffic.
The Cisco ASR 900 Series router 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 interfaces. The Cisco ASR 900 Series also supports Synchronous Ethernet and IEEE 1588, and can act as the source for network clocking for TDM, SDH and SONET, Synchronous Ethernet, and GPS interfaces.
In addition to the timing services, the Cisco ASR 900 Series router can be deployed in small and harsh environments because of its shallow depth and qualification for extended temperature ranges.
Metro Ethernet Aggregation
The Cisco 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, fully redundant aggregation platform is needed. The Cisco ASR 900 Series router offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.
