2. Complete Detailed Product Overview

Product Line Positioning

Cisco ASR 901-10G is the high-bandwidth upgraded variant of the ASR 901 cell-site router family, differentiated from original 1G-only ASR 901 models by a dedicated native 10GE SFP+ uplink port for high-capacity fiber/microwave backhaul. It retains the compact 1RU hardened rack form factor, ultra-wide temperature tolerance and integrated carrier-grade timing architecture optimized for unmanned outdoor cell cabinets, pole-mounted enclosures and remote industrial sites. The platform offers multiple hardware SKUs to support mixed legacy T1/E1 migration or pure all-IP Ethernet transport, with pay-as-you-grow software licensing for throughput, security, timing and pseudowire scale, perfectly matching evolving 4G/5G RAN convergence demands and utility field area network transport requirementsCisco.

- A901-6CZ-F-D: Pure Ethernet without TDM interfaces
- A901-6CZ-FS-D: Simplified all-Ethernet SKU for low-cost all-IP cell sites
AC-powered models (100–240VAC wall power):
- A901-6CZ-FT-A: TDM + Ethernet integrated
