NIM-2FXS/4FXO Description
The NIM-2FXS/4FXO is a Cisco analog voice Network Interface Module for Cisco 4300 and 4400 Series ISRs that serve both analog stations and analog trunk lines at a branch site. The module pairs two FXS/FXS-E/DID ports with four ground-start or loop-start FXO ports, uses onboard DSP with a 128 ms echo tail, and runs on Cisco IOS XE 3.14.3 or later. The FXS ports are an Off-Premises Extension Lite design that is not fully compliant for off-premises use, and DID mode takes incoming calls only, without caller ID.

Application Scenarios
In a branch office, the router terminates up to four analog PSTN or PBX lines on the FXO ports while the two FXS ports keep a fax machine and an analog phone on the same voice gateway.
Sites in North America that route emergency calls over analog CAMA trunks can connect those trunks to the FXO ports and carry E-911 calls from the router over them.

NIM-2FXS/4FXO and NIM-2FXS/4FXOP share the same six ports and functions, but the P version is a newer hardware revision that needs Cisco IOS XE 16.5 or later, where NIM-2FXS/4FXO runs from XE3.14.3. A router held on a release older than 16.5 needs NIM-2FXS/4FXO, because the P version boots there without showing its analog ports. Sites that only connect phones, fax machines or DID lines can order NIM-2FXS, and sites that only terminate PSTN or PBX lines can order NIM-4FXO; both run from XE3.13.4. All four modules carry onboard DSP, so none of them adds a PVDM to the order.
Ordering Checklist
- Supported hosts: Cisco 4300 and 4400 Series ISRs, in an integrated NIM slot or an SM-X slot fitted with a NIM carrier card. Cisco 2900 and 3900 Series ISRs do not support the module.
