The Cisco ASR 901 Series Aggregation Services Router is a compact, high-performance platform designed to meet the demands of modern mobile backhaul and Ethernet access networks. Engineered for deployment in space-constrained environments, the ASR 901 supports both Layer 2 and Layer 3 services and includes key carrier-grade features such as hardware-based operations, administration and maintenance (OAM), advanced timing synchronization with IEEE 1588v2 and SyncE, and resilient network design. With support for Gigabit and 10 Gigabit Ethernet interfaces, it provides flexible connectivity options for service providers looking to deliver business services, aggregate small cells, or migrate legacy transport networks, all within a small and ruggedized form factor suitable for both indoor and outdoor installations.
Carritech supports operators and service providers using the Cisco ASR 901 by sourcing equipment tailored to their specific requirements. Whether you’re maintaining legacy infrastructure or planning a network expansion, our global network of trusted suppliers allows us to locate and supply ASR 901 routers and components that meet your technical and operational standards. Every unit we source is carefully vetted and tested to ensure reliability, and our experienced team is on hand to provide advice, logistics coordination, and long-term support throughout your equipment lifecycle.

| Time Period | Brand / Company | Role / Notes |
|---|---|---|
| 2012 – 2021 | Cisco Systems, Inc. | Original developer, manufacturer, and sole marketer of the ASR 901 Series. |
| 2021 – Present | Cisco (via resellers & partners) | Cisco stopped actively promoting the ASR 901 as a lead product, transitioning customers to newer platforms (e.g., ASR 920, NCS series), but authorized resellers and secondary market partners continued to support sourcing and maintenance. |
| Present (Secondary Market) | Independent Resellers, Third-party Support Specialists (e.g., Carritech) | After Cisco End-of-Sale/EoL, sourcing and lifecycle support shifted to the secondary market. Companies like Carritech now support sourcing, maintenance, and lifecycle extension. |
