HWIC-4A/S Use Case
High-Density Synchronous WAN Aggregation for Branch Offices
Scenario: A national retail chain leverages the Cisco HWIC-4A/S-4-Port Async/Sync Serial HWIC High-Speed WAN Interface card in ISR routers to terminate four fractional T1/E1 circuits per location, aggregating up to 8 Mbps of resilient WAN bandwidth. This modular interface card consolidates connectivity, reduces chassis count and accelerates deployment. Outcome: 40 % smaller hardware footprint, seamless provisioning, and SLA-driven scalability for high-availability branch networks.
Redundant SCADA and Asynchronous Dial-Up Backup for Critical Infrastructure
Scenario: A utility operator installs the Cisco HWIC-4A/S-4-Port Async/Sync Serial HWIC High-Speed WAN Interface card on remote-site routers to support synchronous serial SCADA telemetry and host asynchronous dial-up modems for automatic failover. By combining sync and async ports in a single card, the solution streamlines site rollouts and minimizes points of failure. Outcome: Deterministic data delivery, instant backup activation, and 99.99 % uptime for mission-critical operations.
Centralized Industrial Device Consolidation in Manufacturing
Scenario: A manufacturing plant deploys the Cisco HWIC-4A/S-4-Port Async/Sync Serial HWIC High-Speed WAN Interface card on ISR routers to directly onboard PLCs, HMIs and barcode scanners via four async serial ports—eliminating separate terminal servers. Centralized policy enforcement and secure WAN transport unify device management. Outcome: 25 % reduction in cabling complexity, improved maintenance efficiency, and standardized security compliance across the industrial network.
