A regional bank deploys the C2811-4SHDSL/K9 with HWIC-4SHDSL at its branch offices to establish four-pair G.SHDSL links, delivering up to 15 Mbps of symmetric bandwidth over existing copper loops. This setup ensures low-latency encrypted data transport for real-time transaction processing, high-availability failover, and predictable SLAs. Outcome: continuous 24/7 connectivity with sub-2ms jitter, reduced MPLS costs by 40%, and enhanced compliance with financial data-security regulations.
An internet service provider integrates the C2811-4SHDSL/K9-2811 router with SP Svcs and 128F/512D licensing to deliver converged data, voice, and managed firewall services to underserved rural and SMB locations. The four-pair G.SHDSL bundle extends symmetric upload/download speeds up to 15 Mbps without new fiber deployments. Outcome: rapid time-to-market for premium service tiers, a 30% increase in ARPU, and simplified remote provisioning via zero-touch HWIC-4SHDSL rollout.
A healthcare provider equips its emergency data center with the C2811-4SHDSL/K9 and HWIC-4SHDSL as a fallback transport over copper in the event of fiber or microwave link failure. The SP Svcs subscription and 128F/512D feature set enable secure IPsec VPN tunnels and dynamic routing updates over four-pair G.SHDSL. Outcome: under-5-minute network switchover, adherence to RTO/RPO mandates, and uninterrupted access to electronic health records during outages.
