Overview
The Cisco ASR 901 series aggregation services routers are environmentally hardened, high-speed, low-power-consumption routers optimized for any-generation cell-site Radio Access Network (RAN) backhaul and Ethernet access. By using Cisco ASR 901 routers, operators can reduce backhaul operating costs, simplify and converge their RAN and Ethernet access networks, and enhance their profit opportunities with mobile and premium Ethernet services.¦RAN cell sites are places of transformation between mobile radio and mobile transport networks. Cost-effective RAN backhaul requires the ability to simultaneously aggregate the transport of traffic from both traditional and next-generation radios across multiple transport options available at the cell site. The Cisco ASR 901 routers are designed to minimize operating costs and optimize this radio-to-transport transformation through scalable time-division multiplexing (TDM) and IP/Ethernet interfaces for any combination of multivendor, multigeneration radios and transport networks.
"Green" hardware Cisco ASR 901 routers help service providers reduce operating costs by optimizing energy efficiency, allowing cost-effective and responsible resource management. The routers are designed for low power consumption with Reduction of Hazardous Substances (RoHS) compliant, lead-free components. An indirect benefit is a significant reduction of carbon emissions. Comprehensive services With the Cisco ASR 901 routers, services can be prioritized and differentiated through hierarchical quality of service (HQoS) and security attributes. The routers offer advanced traffic analytics and performance monitoring and control, including per-traffic-class metering, bidirectional packets, and byte statistics. The service offering is enhanced with comprehensive OAM functionality, including Layer 2 CFM, IP service-level agreements (SLAs) for Layer 3, and MPLS OAM and TDM advanced timing and synchronization. Service scalability The Cisco ASR 901 routers deliver line-rate performance and flexible service scalability in a compact form factor. With support for up to 32,000 MAC addresses, up to 4000 bridge domains, and multiple hierarchical queues, the routers deliver high performance and scale for all mobile and Carrier Ethernet services. Advanced timing The Cisco ASR 901 routers provide the timing services required in today's converged access networks by offering integrated support for the BITS, 10-MHz, 1 Pulse Per Second (PPS), and Time of Day (ToD) interfaces. The routers support SyncE on copper and optical ports and IEEE1588v2 Precision Time Protocol (PTP) clock recovery from T1/E1 ports. Network simplification Cisco network virtualization (nV) technology can simplify network operations by reducing the number of components that must be managed, supporting easier configuration. The result is increased network scalability, improved service velocity, and lower operating costs. The nV-capable Cisco ASR 901 routers can be deployed as satellites of a Cisco ASR 9000 series system to reduce the complexity of today's mobile Internet networks.
