A9K-16T/8-B Use Case
Scalable Metro Ethernet Business Services
A regional service provider deploys the Cisco ASR 9000 with the A9K-16T/8-B 16-Port 10GE DX Medium Queue Line Card (requires SFPs) to aggregate multi-gigabit business Ethernet circuits across its metro ring. The line card’s medium-queue architecture enforces strict SLAs, mitigates congestion during traffic spikes, and delivers sub-5 ms latency with 99.99% availability. Outcome: rapid service activation, consistent performance under load, and up to 40% reduction in operational costs through unified aggregation.
Carrier-Grade 5G Mobile Backhaul Transport
A national mobile operator uses the A9K-16T/8-B line card in its ASR 9000 core to backhaul 4G/5G traffic from distributed cell sites. Sixteen 10GE DX SFP-based ports combined with medium-queue buffering ensure deterministic latency, packet prioritization for VoNR and eMBB services, and seamless scaling under peak loads. Outcome: 30% improved QoS for end users, simplified capacity expansion, and 99.999% network uptime.
High-Performance Enterprise Campus Core
A global financial institution consolidates multiple campus distribution layers into a centralized Cisco ASR 9000 core using the A9K-16T/8-B 16-Port 10GE DX Medium Queue Line Card. The solution delivers deterministic performance for latency-sensitive trading applications and real-time backup replication, while SFP-based fiber connectivity provides deployment flexibility and minimal rack footprint. Outcome: 50% lower network latency, streamlined operations, and enhanced reliability for mission-critical services.
