WIC-1DSU-56K4 Use Case
Rural Branch Office Dedicated WAN Connectivity
A regional bank deploys the Cisco WIC-1DSU-56K4-1-port 4-WIRE 56/64 KBPS WAN Interface Card on its branch router to leverage a 4-wire 56 kbps leased line where broadband is unavailable. By provisioning a dedicated DSU/CSU circuit, the branch achieves consistent transaction throughput, deterministic latency and carrier-grade reliability. Benefit: SLA-compliant uptime, predictable performance for core banking applications and reduced TCO compared to satellite or MPLS alternatives.
Industrial SCADA Remote Monitoring Over Low-Speed Link
An oil & gas operator integrates the Cisco WIC-1DSU-56K4-1-port 4-WIRE 56/64 KBPS WAN Interface Card into its SCADA master router to connect offshore pump stations via existing 4-wire 64 kbps circuits. This configuration delivers real-time telemetry, alarm notifications and remote configuration over a secure, low-latency channel. Benefit: 24/7 operational visibility, 30 % reduction in field service visits and deterministic data delivery for critical infrastructure control.
Secure Retail POS Payment over Dedicated DSU/CSU Link
A retail chain leverages the Cisco WIC-1DSU-56K4-1-port 4-WIRE 56/64 KBPS WAN Interface Card to connect store POS terminals to a central payment gateway via a leased 56 kbps line. The dedicated DSU/CSU link ensures 99.99 % transaction reliability, PCI-DSS compliant encryption tunneling and isolated connectivity. Benefit: uninterrupted credit-card processing, fortified data integrity and a 20 % reduction in per-store communication expenses.
