Cisco NIM-2BRI-NT/TE Module – Dual BRI Ports , ISDN Voice/Data
Support For Cisco Routers
The Cisco NIM-2BRI-NT/TE is a high-performance Network Interface
Module (NIM) designed to provide ISDN Basic Rate Interface (BRI)
connectivity for Cisco routers. Featuring dual S/T ports, this
module supports both Network Termination (NT) and Terminal
Equipment (TE) modes, making it ideal for voice, data, and backup
WAN applications. Compatible with Cisco ISR-G2 routers (2900, 3900,
4000 series), it enables seamless integration with legacy PBX
systems, VoIP gateways, and ISDN-based networks.
Key Features & Benefits
✔ Dual BRI S/T Ports – Supports 2 ISDN BRI connections (up to 128
Kbps per port), ensuring flexible deployment in NT or TE mode.
✔ Reliable ISDN Connectivity – Enables voice calls, fax, and data
transfer over ISDN networks with low latency and high stability.
✔ Backup WAN Solution – Acts as a failover link for primary
broadband connections, ensuring business continuity.
✔ Cisco IOS Compatibility – Easily managed via Cisco CLI or Prime
Infrastructure, with support for QoS, VoIP, and ISDN protocols
(DSS1, ETSI, ANSI).
✔ Enterprise-Grade Hardware – Built for 24/7 operation, with low
power consumption and hot-swappable NIM slot support.
