NIM-2FXS/4FXOP Use Case
Branch Office Analog Telephony Integration
In a multi-site enterprise deploying a Cisco ISR router with the NIM-2FXS/4FXOP-Voice Module, IT teams connect up to two analog desktop phones (FXS) and four PSTN trunks (FXO) at each remote office. This setup preserves existing analog handsets, streamlines local outbound/inbound dialing, and reduces capital spending on new IP phones. Benefit: Rapid branch-office deployment with uninterrupted analog service and optimized telephony costs.
Disaster Recovery and Emergency PSTN Failover
A financial services firm uses the NIM-2FXS/4FXOP-Voice Module within its primary Cisco ISR to implement PSTN fallback for critical voice traffic. Upon WAN or SIP trunk failure, calls automatically route through the four FXO ports to local PSTN lines, while two FXS ports maintain analog paging and alarm systems. Benefit: Guaranteed voice continuity with zero-touch failover, safeguarding business-critical communications and compliance with uptime SLAs.
Legacy PBX Modernization in Remote Healthcare Clinics
A regional healthcare network migrates small clinics from aging key systems to a centralized IP-PBX. By installing the NIM-2FXS/4FXOP-Voice Module on-site, clinics retain analog exam-room phones and fax machines via FXS ports, while routing patient-appointment lines through FXO ports to the cloud PBX. Benefit: Phased migration with minimal disruption, preserved medical device integrations, and consolidated voice management for improved operational efficiency.
