Cisco Systems A901-4C-F-D

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.
