Dependable BRI performance.
Reliable legacy WAN support.
The Cisco NIM-2BRI-NT/TE is a 2-port Network Interface Module for ISDN BRI in Network Termination (NT) and Terminal Equipment (TE) modes, designed for Cisco routers.
The NIM-2BRI-NT/TE supports two independent ISDN Basic Rate Interface (BRI) ports, each providing two 64 kbps B-channels and one 16 kbps D-channel.
In NT (Network Termination) mode, the module emulates the network side of ISDN; in TE (Terminal Equipment) mode, it emulates customer premises equipment for direct device connectivity.
The NIM-2BRI-NT/TE is compatible with Cisco ISR 1900, 2900, 3900, 4000 Series and other platforms featuring a Cisco NIM slot and supported Cisco IOS images.
Power down the router, insert the NIM-2BRI-NT/TE into an available NIM slot, secure the module with screws, and power up to auto-detect the interface.
In Cisco IOS global configuration, set the switch type (e.g. isdn switch-type basic-net3), enter interface bri, apply 'service nt', and configure IP or dialer profiles as needed.
In global configuration, set the ISDN switch type, enter 'interface bri x/y', apply 'service te', assign a dialer profile, and configure authentication or CLID as required.
Each port aggregates up to 144 kbps (2×64 kbps B-channels + 16 kbps D-channel), delivering reliable ISDN connectivity for voice and data services.
The module uses standard RJ-45 connectors wired for 4-wire ISDN BRI cables, ensuring compatibility with existing ISDN infrastructure.
Under typical conditions, ISDN BRI supports up to 4 km of 0.4 mm copper wire; maximum reach can extend to 8 km with enhanced cabling and repeaters.
No. To ensure system stability and hardware integrity, the NIM-2BRI-NT/TE must be installed or removed only when the router is powered down.
The module draws power directly from the router’s internal backplane; no external power supply is required.
The NIM-2BRI-NT/TE supports standard ISDN protocols including Q.921 (LAPD) for D-channel framing and Q.931 for call setup and teardown.
Typical applications include voice/fax over ISDN, small PBX connectivity, remote office backup links, and legacy ISDN-based data services.
Use 'show interface bri x/y' to check line status, B-channel activity and 'show isdn status' for D-channel signaling and call statistics.
The NIM-2BRI-NT/TE includes a one-year limited hardware warranty. Cisco Smart Net Total Care support contracts are available for extended coverage.
