    Full-featured, efficient aggregation platform

    The 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 benefits

    Broadband aggregation

    Deliver a greatly enhanced broadband customer experience. This series supports broadband aggregation for voice, video, data, and mobility services. It supports thousands of subscribers, and QoS scales to a large number of queues per device.

    Pre-aggregation for mobile applications

    Deployed as a pre-aggregation platform for mobile backhaul, the series can aggregate cell sites and use MPLS as a transport for RAN backhaul traffic.

    Timing services

    Get the timing services required in today’s converged access networks. The series offers integrated support for a variety of interfaces and can act as the source for network clocking for GPS and other interfaces.

    Suitable for harsh environments

    Because of its shallow depth and qualification for extended temperature ranges, the series can be deployed in small and harsh environments.

    Metro Ethernet Aggregation

    Built to meet service provider requirements for Carrier Ethernet aggregation, the series is optimized for remote central office and smaller sites that need a full-featured, modular, small-footprint, fully redundant aggregation platform.


    A903-RSP1B-55 Overview

    Cisco A903-RSP1B-55 is the Cisco ASR 903 Route Switch Processor. Cisco ASR 900 Series RSP modules contain separate control plane and data plane components. These include the main control plane CPU for the Cisco IOS Software operating system and platform control software. The data-plane packet processing and traffic management is performed by the Carrier Ethernet application-specific integrated circuit (ASIC).
