Scenario: A global finance firm deploys the Cisco C3825-H-VSEC/K9-3825H.Perf.VSEC:AIM-VPN3/SSL,PVDM2,CCME/SRST,AIS,512F/1024D to establish AES-256 IPsec tunnels and SSL VPN endpoints between 120 branch offices and its data centers. The integrated AIM-VPN3 hardware module offloads encryption, while AIS guarantees line-rate throughput. Benefit: Achieves PCI DSS compliance, reduces VPN CPU overhead by 35%, and maintains sub-5 ms inter-site latency—ensuring secure, high-performance connectivity for critical financial transactions.
Scenario: A national retail chain uses the C3825-H-VSEC/K9-3825H.Perf.VSEC:AIM-VPN3/SSL,PVDM2,CCME/SRST,AIS,512F/1024D in each store to host Cisco CallManager Express (CCME) for up to 50 IP phones per location. PVDM2 voice modules handle HD audio, while SRST automatically switches calls to PSTN circuits during WAN outages. Benefit: Guarantees 99.99% voice uptime and seamless call continuity, reduces revenue-loss risk during connectivity failures, and streamlines branch-level telephony provisioning under a single appliance.
Scenario: A regional ISP leverages the C3825-H-VSEC/K9-3825H.Perf.VSEC:AIM-VPN3/SSL,PVDM2,CCME/SRST,AIS,512F/1024D as an edge router to manage up to 40 Gbps aggregate traffic, enable Stateful Firewall, and perform deep packet inspection. The Advanced Integration Services (AIS) bus accelerates QoS, NAT and NetFlow while ample DRAM buffers 200 K concurrent sessions. Benefit: Delivers carrier-grade performance with sub-10 µs forwarding latency, scales session capacity by 4×, and reduces capital expenditures by consolidating routing, security and analytics in one platform.
