• 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, quality of service (QoS) on the Cisco ASR 900 Series router is capable of scaling up to a large number of queues per device. This large number of queues, combined with a highly granular QoS algorithm (three-level hierarchical QoS), results in a greatly enhanced broadband user experience. This full-featured Layer 2 and Layer 3 switch router supports a variety of broadband applications including IPTV and video on demand (VoD), enhancing and extending the Cisco IP Next-Generation Network (IP NGN) architecture.
• 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 (TOD) interfaces. The Cisco ASR 900 series 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, SyncE, and GPS interfaces. In addition to the timing services, the Cisco ASR 900 series router can be deployed in small and harsh environments, due to 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.
• High availability and modularity
  The Cisco ASR 900 series router is a fully modular platform. Cisco offers a choice of multiple distinct route switch processors (RSPs), AC and DC power supplies, a fan tray and a wide range of interface modules. The Ethernet interfaces are available in copper and fiber, with speed ranging from 10 Mbps to 10 Gbps.
• Operational efficiency
  The Cisco ASR 900 series router features essential capabilities that help service providers simplify and automate the management of their networks, resulting in efficiency gains in the deployment and operation of the networks. The Cisco ASR 900 series router provides proactive diagnostic tools including Generic On-Line Diagnostics (GOLD) which will help service providers avoid potential problems before they occur, troubleshoot any problems, and when these are diagnosed, implement solutions.
• Fan tray
  Cisco ASR 900 series routers have a single fan tray slot, which must be populated for the system to operate. The systems have been designed to remain operational during the replacement of the fan tray. In addition to cooling the chassis, the fan tray also contains a connector for dry-contact inputs and several system-level alarm LEDs.

Cisco ASR 900 series aggregation services router is full-featured, modular aggregation platforms. It is 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.
