HWIC-2A/S Use Case
Enterprise Multi-Site WAN over T1/E1 Links with HWIC-2A/S-2-Port Async/Sync Serial WAN Interface Card
In a global retail chain, IT teams install the HWIC-2A/S-2-Port Async/Sync Serial WAN Interface Card on edge Cisco routers to terminate T1/E1 leased lines at multiple branch locations. By leveraging its dual async/sync ports and built-in clocking (DCE/DTE), the solution delivers up to 2.3 Mbps per port for low-latency, deterministic connectivity. Outcome: simplified branch deployment, predictable throughput for POS and inventory systems, and 99.99% uptime for critical business operations.
Carrier-Grade Backup and Failover for Service Provider MPLS Peering
A regional telecom operator integrates the HWIC-2A/S-2 into core Cisco routers as a resilient backup path for primary MPLS circuits. The card’s support for sync serial interfaces and HDLC/PPP encapsulation enables rapid failover in under 300 ms, maintaining SLAs during fiber cuts or outages. Outcome: seamless customer experience, preserved revenue streams, and compliance with uptime guarantees across enterprise accounts.
Secure Industrial SCADA Connectivity in Remote Automation Sites
In an oil & gas facility, engineers deploy the HWIC-2A/S-2-Port Async/Sync Serial WAN Interface Card on ruggedized Cisco routers to link RTUs and PLCs over dedicated serial links. The high-speed serial channels ensure real-time telemetry and deterministic control loops, while integrated CSU/DSU eliminates external hardware. Outcome: enhanced process safety, reduced latency for critical commands, and lower CAPEX through consolidated network infrastructure.
