FAQ
What is the difference between FXO and FXS?
FXO ports connect to the PSTN or PBX trunk side, while FXS ports connect to analog endpoints such as phones or fax machines. The NIM-2FXO enables the router to connect to analog PSTN office lines.
Does the NIM-2FXO need an external DSP?
No, the module includes a dedicated DSP for TDM analog voice services, so no additional DSP resources are required from the ISR 4000 platform.
Can it be installed while the router is running?
Yes, OIR support allows the NIM-2FXO to be installed or replaced without powering down the Cisco 4000 ISR.

Frequently Asked Questions
What types of phone lines does the NIM-2FXO connect to?
The NIM-2FXO connects to PSTN office lines, allowing your ISR 4000 router to integrate analog telephone service with your data network and enable VoIP or hybrid voice solutions.
Can the NIM-2FXO replace separate analog telephone interfaces?
Yes, the 2-port module lets you consolidate up to two analog office lines into a single card, reducing hardware footprint while maintaining PSTN connectivity.
What is the role of the dedicated DSP in this module?
A dedicated DSP (Digital Signal Processor) handles voice encoding and decoding, ensuring call quality when converting between analog PSTN lines and IP-based voice services.
Is the NIM-2FXO suitable for small offices with limited phone lines?
Yes, small branches or departmental offices needing two analog connections benefit from the simplified hardware approach and integrated platform design.
Can I hot-swap this module without losing PSTN connectivity?
Yes, the NIM-2FXO supports Online Insertion and Removal (OIR), though PSTN calls on that module will be interrupted during the swap. Plan upgrades during low-usage windows.
What happens if I need more than two analog phone lines?
Install additional analog voice NIMs (like NIM-4FXO) in the available NIM slots of your ISR 4000 to scale up to more PSTN connections as your office grows.
