C1121-4PLTEP Use Case
Real-Time Fleet Telematics and Asset Tracking
In a national logistics operation, the C1121-4PLTEP-ISR 1100 4P DUAL GE SFP RTR PLUGGABLE SMS/GPS connects vehicle CAN-bus sensors, in-cabin cameras (via GE SFP uplinks) and GPS receivers to a central fleet-management platform. If a truck deviates from its route or experiences a mechanical fault, the router issues instant SMS alerts and transmits location and diagnostic data over LTE. Benefit: Achieves 24/7 visibility, accelerates incident response by 30%, and reduces fleet operating costs through proactive maintenance.
Secure Retail POS Connectivity with LTE Failover and SMS Alarms
A multi-store retailer uses fiber-backed dual GE SFP links for payment terminals and in-store Wi-Fi. By deploying the C1121-4PLTEP-ISR 1100 4P DUAL GE SFP RTR PLUGGABLE SMS/GPS as an LTE backup, each site automatically fails over on primary network loss. The integrated SMS engine notifies IT teams of connectivity events, while GPS logs store location. Benefit: Delivers 99.99% POS transaction uptime, prevents revenue loss during outages, and simplifies PCI DSS compliance with end-to-end encryption and audit-ready logs.
Resilient Industrial IoT and SCADA Edge Connectivity
In a remote oil & gas pipeline SCADA deployment, the C1121-4PLTEP-ISR 1100 4P DUAL GE SFP RTR PLUGGABLE SMS/GPS aggregates four RTU LAN segments, interfaces with fiber-optic GE SFP backhaul, and uses GPS time-sync for event logging. On threshold breaches, it sends SMS alarms to control-room operators and switches traffic to LTE without human intervention. Benefit: Ensures continuous telemetry, reduces site-visit maintenance by 40%, and enhances operational safety through always-on, low-latency edge connectivity.
