The NM-4B-U= is a Cisco Interface Module designed specifically for integrating ISDN-BRI connections into compatible Cisco routers. This module features four ISDN-BRI ports, allowing for multiple ISDN connections to function simultaneously. These connections are essential for establishing medium-speed data transfers, supporting both voice and data communication through the digital signaling of ISDN lines.
Each of the four ISDN Basic Rate Interface (BRI) ports offers two 64kbps B-channels and a 16kbps D-channel, which are used for digital signaling and data transmission. This makes the NM-4B-U= highly suitable for companies or small offices needing multiple ISDN connections for their telecommunication or WAN infrastructure. The module’s digital nature means that it directly supports modem functionality, eliminating the need for external modems when creating ISDN-based networks or remote access setups.
Physically, this module is designed for ease of installation with compatible Cisco modular routers. It occupies a network module slot, delivering reliable performance for standard ISDN connectivity. One of the key features of the NM-4B-U= is its capability to be hot-swappable, meaning it can be replaced or upgraded without shutting down the network device. This ensures minimal service disruption and maximum uptime for business-critical communication systems.
In terms of compatibility, it integrates seamlessly with selected Cisco products, enabling flexible and reliable ISDN connectivity across various network configurations. The robust design and proven reliability of Cisco hardware make this module an excellent choice for businesses requiring multiple ISDN connections in one router setup.
