A multinational corporation deploys WIC-2A/S-2-Port Async/Sync Serial WAN Interface Cards in ISR routers at 50+ branch offices to aggregate two T1/E1 leased lines for primary and backup connectivity. This setup delivers resilient, higher-throughput WAN links, reduces hardware footprint and management overhead, and ensures seamless failover for critical business applications.
An energy provider integrates WIC-2A/S-2-Port Async/Sync Serial WAN Interface Cards into remote terminal unit (RTU) enclosures to establish dedicated synchronous links for SCADA data collection over long-haul microwave and fiber circuits. The solution guarantees deterministic latency, robust error correction and 24/7 uptime, enabling real-time monitoring of remote assets and streamlined operational control.
A retail bank leverages the asynchronous ports of the WIC-2A/S-2-Port Async/Sync Serial WAN Interface Card to connect dispersed ATMs and POS terminals across dial-up and leased-line backups. This configuration ensures flexible protocol support, secure transaction delivery and continuous availability, minimizing downtime and reducing network maintenance costs.
