Cisco ASR 903 Modular expansion base rack-mountable

The Cisco ASR 903 Router is a full-featured aggregation platform designed for the cost-effective delivery of converged mobile and business services. With redundancy, shallow depth, low power consumption and high service scale, this 3-rack-unit (3RU) router is optimized for small aggregation and remote point-of-presence (POP) applications. The Cisco ASR 903 Router provides a comprehensive and scalable feature set of Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in a compact package.

The Cisco ASR 903 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 903 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.

The Cisco ASR 903 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, small-footprint, fully redundant aggregation platform is needed. The Cisco ASR 903 Router offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.
