HWIC-4T Use Case
Multi-Branch WAN Connectivity Optimization with Cisco HWIC-4T-4-Port Serial HWIC
In a retail franchise environment, four remote stores connect to headquarters over dedicated 8 Mbps serial links using the Cisco HWIC-4T-4-Port Serial High-Speed WAN Interface Card. This setup delivers simultaneous POS transactions, real-time inventory synchronization and VoIP over a single router, reducing latency, simplifying management and ensuring consistent customer service.
Secure Industrial Control Network Integration via 8 Mbps Serial Links
A manufacturing plant deploys the Cisco HWIC-4T-4-Port Serial HWIC to link four production-line SCADA segments to the central control center with isolated 8 Mbps WAN circuits. This architecture enforces network segmentation, guarantees deterministic performance for critical PLC traffic and meets industry safety and compliance standards.
High-Availability Disaster Recovery with Aggregated T1/E1 Circuits
An enterprise data center uses the HWIC-4T-4-Port Serial High-Speed WAN Interface Card to aggregate four 8 Mbps T1/E1 links, delivering 32 Mbps of resilient WAN capacity for off-site backup and database replication. The result is sub-15 minute RPO, automated failover and cost-effective utilization of existing serial infrastructure.
