Introduction
The ASR 901S Series Aggregation Services Router is a small cell, environmentally-hardened (IP65 rated),
low-power, cost-effective router. This small cell router (SCR) is designed to support small cell networks to
increase capacity and coverage, thereby reducing operational expenses.
These routers provide carrier class metro Ethernet access connectivity in small cell areas and support
packet-based synchronization based on IEEE1588 and synchronous Ethernet.
The ASR 901S Series Aggregation Services Router is compact and can be easily deployed in challenging
locations such as lamp posts, side walls, telephone poles, and cabinets.
