Cisco ASR 901 - Router - GigE, HDLC, PPP, TDM, MLPPP - Rack-mountable - Refurbished - A901-4C-FT-D-RF

• Cell-site backhaul for mobile applications
  Deployed as cell-site routers for mobile backhaul, the Cisco ASR 901 router can aggregate multiple base stations through multiple TDM, Ethernet, and IP interfaces, and can use Multiprotocol Label Switching (MPLS), Resilient Ethernet Protocol (REP), Multilink Point-to-Point Protocol (MLPPP), Layer 3 VPN (L3VPN), and other common transport protocols for RAN backhaul.
• Metro Ethernet access
  Cisco ASR 901 router allows service providers to simultaneously manage and operate Pseudowire Emulation Edge to Edge (PWE3) and Carrier Ethernet environments by supporting line-rate Layer 2 Ethernet operations, administration, and maintenance (EOAM), including Connectivity Fault Management (CFM), Ethernet Local Management Interface (ELMI), Ethernet in the First Mile (EFM), Resilient Ethernet Protocol (REP), and QinQ.
• Business access device
  Cisco ASR 901 router is optimized for remote-access and small aggregation sites where a fully featured, compact access platform is needed. The router offers business service flexibility using an Ethernet virtual circuit (EVC) infrastructure and delivers Layer 2, IP, and MPLS transport for advanced Layer 2 and Layer 3 VPN services.
• "Green" hardware
  Cisco ASR 901 routers helps service providers reduce operating costs by optimizing energy efficiency, allowing for cost-effective and responsible resource management. The router is designed for low power consumption with RoHS-compliant/lead-free components. An indirect benefit is a significant reduction of carbon emissions.
• Service richness
  With the Cisco ASR 901 router, services can be prioritized and differentiated through hierarchical quality of service (HQoS) and security attributes. The router offers 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.
• Service scale
  The Cisco ASR 901 router delivers line-rate performance and flexible service scalability in a compact form factor. The router delivers high performance and scale for all mobile and Carrier Ethernet services.
• Advance timing
  The Cisco ASR 901 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 (PPS), and Time of Day (ToD) interfaces. The routers support SyncE on copper and optical ports and IEEE1588v2 Precision Time Protocol (PTP).
• 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 ASR 901 router can be deployed as components in a Cisco ASR 9000 series system to reduce the complexity of today's mobile Internet networks.

The Cisco ASR 901 series Aggregation Services Router is environmentally hardened, high-speed, low-power-consumption routers optimized for any-G cell-site Radio Access Network (RAN) backhaul and Ethernet access. By using the Cisco ASR 901 router, 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 legacy and radios across multiple transport options available at the cell site. The Cisco ASR 901 router is 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.
The Cisco ASR 901 series Aggregation Services Router is compact cell-site and Ethernet access routers specifically designed to clock, aggregate, and backhaul mixed-generation RAN traffic. Cisco ASR 901 router prioritizes and processes cell-site voice, data, and signaling traffic as part of the Cisco unified RAN backhaul solution for reliable transport across any available backhaul networks, including T1/E1, ATM, Carrier Ethernet, microwave, WiMAX, and service provider Wi-Fi networks.
