4-Ports RJ-45 + 8-Ports SFP + 2-Ports SFP+ Switch

The Cisco ASR 901 Series Aggregation Services Routers are compact cell-site and Ethernet access routers specifically designed to clock, aggregate, and backhaul mixed-generation RAN traffic. Cisco ASR 901 routers prioritize and process 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.

Designed for cell sites and Carrier Ethernet access, the Cisco ASR 901 differentiating features include:
- Low power consumption
- Line rate performance for all Layer 2 and Layer 3 interfaces
- Flexible clocking options: TDM, Building Integrated Timing Supply (BITS), GPS (10Mhz, 1PPS/ToD),1588v2, and Synchronous Ethernet (SyncE)
- Secure Mobile Transport: with IPSec and Network Address Port Translation (NAPT)
- Extended operating temperatures
- Small form factor: 1 rack unit (RU) with 8.3 - 9.1 in. depth
- Redundant power and cooling
- Pay-as-you-grow investment model
