NIM-2FXO Use Case
PSTN Failover for Business Continuity with Cisco NIM-2FXO-Voice Module
In a mid-sized retail branch deploying a Cisco ISR router, the NIM-2FXO-Voice Module provides automatic PSTN failover when the IP WAN link degrades or fails. This ensures uninterrupted inbound/outbound voice connectivity, preserves customer service levels during outages, and drives up to 99.9% voice uptime for critical operations.
Legacy Analog Device Integration in Remote Sites
A manufacturing enterprise uses the 2-port FXO module in its Cisco ISRs to connect remote-site analog fax machines, alarm panels and credit-card terminals directly into its centralized VoIP infrastructure. The solution unifies management and billing, enables real-time call monitoring, and cuts analog trunk provisioning by up to 40%, maximizing ROI on existing hardware.
Local Breakout for Toll Bypass and Cost Optimization
A global services firm deploys NIM-2FXO-Voice Modules at regional branch offices to route local and emergency calls directly to the PSTN rather than backhauling over the corporate WAN. This local-breakout strategy reduces toll charges by up to 25%, lowers voice latency, simplifies regulatory compliance, and delivers measurable OPEX savings across all sites.
