NIM-2FXS/4FXOP= Use Case
Hybrid PSTN–VoIP Gateway for Branch Offices with NIM-2FXS/4FXOP Module
In a multi-site enterprise, deploy the NIM-2FXS/4FXOP 2-Port FXS/FXS-E/DID & 4-Port FXO Network Interface Module on Cisco ISR routers to bridge local PSTN trunks and legacy analog handsets with SIP-based UC platforms. Benefit: Enables seamless voice routing, slashes telephony expenses by up to 30%, and ensures high availability via automatic FXO dial-peer failover.
Direct Inward Dialing (DID) Integration for High-Volume Contact Centers
Contact centers leverage the FXS-E/DID ports on the NIM-2FXS/4FXOP Module to map multiple direct-inward-dial numbers to individual agents, while the 4 FXO ports handle outbound PSTN calls. Benefit: Boosts customer satisfaction with local-number calling, optimizes call distribution, and reduces inbound toll charges by 25%.
Automatic PSTN Failover and Remote Site Telemetry with 4-Port FXO Module
In remote industrial or critical-infrastructure deployments, use the 4-Port FXO side of the NIM-2FXS/4FXOP Module as an automated PSTN backup when IP links degrade, while the 2 FXS ports maintain analog telemetry, alarms, and emergency phones. Benefit: Guarantees uninterrupted voice alerts, strengthens business continuity, and minimizes downtime for mission-critical operations.
