NIM-4E/M Use Case
SMB Legacy PBX Integration with Cisco NIM-4E/M Analog Voice Card
A small-to-medium business (SMB) deploys the Cisco NIM-4E/M on its ISR router to integrate existing analog PBX E&M trunks with IP telephony. By converting mouth-and-ear circuits to SIP, the business preserves legacy voice infrastructure, reduces monthly PSTN fees, and simplifies call routing. Result: seamless migration to unified communications with minimal capital outlay and improved voice uptime.
Contact Center E&M Trunk Connectivity for High-Availability Dial-Out
A 100-agent contact center leverages the NIM-4E/M voice network interface card to terminate analog E&M trunks directly on its Cisco Catalyst router. This setup provides native PSTN fallback, automated trunk failover, and load-balanced dial-out across multiple analog lines. Outcome: enhanced call reliability, reduced latency, and uninterrupted customer outreach during SIP gateway maintenance or carrier outages.
Remote Branch Office Analog Device Support and PSTN Resilience
A distributed retail chain equips its remote branches with NIM-4E/M modules to support analog fax machines, point-of-sale terminals, and legacy handsets. Integrated into the site ISR, the module offers secure voice encryption and local PSTN breakout via E&M interfaces. Benefit: sustained operation of mission-critical analog devices, centralized management, and resilient voice services in WAN failover scenarios.

Questions & Answers
What is the Cisco NIM-4E/M analog voice network interface card?
The Cisco NIM-4E/M is a four-port analog voice network interface module (two FXS and two FXO) designed for seamless integration of analog telephony with Cisco ISR routers.
How many analog voice ports does the NIM-4E/M support?
The NIM-4E/M supports up to four simultaneous analog voice sessions, with each port capable of handling one active call.
What types of ports are included on the NIM-4E/M?
The module includes two RJ-11 FXS (Foreign Exchange Station) ports for telephones and two RJ-11 FXO (Foreign Exchange Office) ports for PSTN line connections.
Which Cisco routers are compatible with the NIM-4E/M?
The NIM-4E/M is compatible with Cisco ISR 4000 and ISR 3900 series routers equipped with a Cisco NIM slot.
How do I install the NIM-4E/M module in my router?
Power down the router, insert the NIM-4E/M into an available NIM slot, secure it with the retention screws, and power the router back on.
What power requirements does the NIM-4E/M have?
The module leverages the router’s internal power supply, drawing approximately 2.4 W across the +3.3 V and +12 V rails.
What voice codecs are supported on the NIM-4E/M?
Supported codecs include G.711 μ-law/A-law, G.729, G.726, and G.723.1, offering flexible bandwidth and quality options.
How do I configure the FXS and FXO ports on the NIM-4E/M?
Use Cisco IOS commands: enter global configuration mode, select each voice-port (e.g., 'voice-port 0/0:0'), set the type to fxs or fxo, and apply dial-peer settings.
What is the maximum number of concurrent calls on the NIM-4E/M?
The module supports up to four concurrent voice calls, one per analog port.
Does the NIM-4E/M support call progress and tone detection?
Yes, it supports call progress analysis, ring voltage generation, dial tone detection, and caller ID per international telephony standards.
Where can I find the configuration guide for the NIM-4E/M?
