Cisco ASR 900 1 Port OC3/STM-1 License | Carrier Access, Licensing — FLSASR900-1OC3

Expand ASR 900 connectivity with a license that enables one OC3/STM-1 port on the platform. Built for environments where access capacity must be added with precision, this entitlement lets network teams scale a deployed ASR 900 chassis without overcommitting to a larger hardware refresh. For service providers and enterprise infrastructure teams, that matters. OC3/STM-1 remains relevant in networks that still depend on established carrier handoffs, legacy aggregation, or transitional WAN architectures. Rather than replacing a stable platform, this license adds the specific interface capacity needed to keep traffic moving and service commitments intact. Because this is a Cisco platform license, it fits procurement models that favor controlled expansion, predictable deployment planning, and alignment with existing ASR 900 investments. It is a practical choice when the requirement is not more hardware, but one more port with the right protocol support. Use it to extend the life and utility of an installed ASR 900 system while keeping network design disciplined and cost-aware. Ideal For Add one OC3/STM-1 handoff to an installed ASR 900 router Extend a carrier edge deployment that still depends on legacy transport Upgrade a branch or aggregation site without replacing the base chassis Support migration environments that require one additional SONET/SDH port Why This Product 1 Adds one licensed port instead of requiring a chassis replacement 2 Supports legacy OC3/STM-1 connectivity for transitional networks 3 Keeps expansion tied to the installed ASR 900 platform 4 Fits controlled procurement for targeted capacity growth
