NM-HDA-4FXS Use Case
Centralized Analog Fax Integration for Retail Chain Compliance
A national retail chain uses the Cisco ISR 4000 series with the NM-HDA-4FXS high-density analog voice/fax network module to consolidate legacy in-store fax machines onto the corporate WAN. By terminating four FXS ports per module directly on-site, stores maintain PCI-DSS compliance for credit-card transaction faxes, eliminate standalone fax servers, and achieve secure, end-to-end encryption and centralized management—reducing hardware costs by 30% and simplifying regulatory audits.
Secure Patient Data Fax and Voice for Healthcare Clinics
A multi-location healthcare provider deploys Cisco routers equipped with NM-HDA-4FXS modules to connect analog fax machines and nurse-call phones over its MPLS backbone. The high-density 4-port FXS interface ensures HIPAA-compliant transmission of sensitive patient records and real-time voice paging. This unified network approach delivers 99.99% uptime, centralized provisioning, and a 40% reduction in monthly telecom expenses by retiring disparate TDM circuits.
Scalable Multi-Site Analog Voice Connectivity in Manufacturing
A global manufacturing firm integrates shop-floor operator consoles, analog alarms, and legacy fax devices using Cisco ISR 4000 routers with NM-HDA-4FXS modules at each plant location. Four FXS ports per module enable high-density analog port consolidation directly into the enterprise IP network. The outcome is streamlined provisioning via Cisco Prime, a 50% reduction in analog trunks, and improved operational visibility with end-to-end QoS monitoring across 20+ sites.
