Full-Featured Converged Access Platforms
The Cisco ASR 920 Series Aggregation Services Routers provide a comprehensive and scalable set of Layer 2 and Layer 3 VPN services in a compact package. They are temperature-hardened, small form factor, with high throughput and low power consumption ideal for mobile backhaul, business services and residential voice, video, and data (“triple-play”) applications.
Features and Capabilities
With the Cisco ASR 920 Series, service providers can initiate MPLS-based VPN services from within the access layer. Designed around key Carrier Ethernet features that simplify network operations, these routers allow you to offer premium services with enhanced SLA capabilities. An optional pay-as-you-grow feature and service activation model give you a flexible, cost-effective solution.
Applications
The ASR 920 Series supports broadband access for delivering voice, video, data, and mobility services. Designed to support thousands of subscribers, QoS on the ASR 920 Series can scale up to a large number of queues per device. This full-featured Layer 2 switch and Layer 3 router supports a variety of broadband applications, including IPTV and video on demand.
Deployed as a converged access platform for mobile backhaul, the ASR 920 Series can aggregate multiple base stations through Ethernet and IP interfaces and can use MPLS as a transport. It provides flexible timing services, with integrated support for multiple interfaces. You can deploy it in small and outside environments, due to its shallow depth and qualification for extended temperature ranges.
The ASR 920 Series is built to meet service provider requirements for Carrier Ethernet access. It is optimized for remote access and smaller aggregation sites where a full-featured, small-footprint converged platform is needed. It offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.
