The Cisco Interface Module with part number NM-8B-U= is an 8-port ISDN-BRI interface module designed for use in network modular architecture. This module provides eight digital ISDN Basic Rate Interface (BRI) ports, delivering high-speed data transmission over ISDN lines. Each of the ports on the NM-8B-U= supports various ISDN features, which are ideal for environments requiring reliable connectivity and access over multiple channels.
Each of the eight ports supports 128 Kbps of bandwidth when connecting to ISDN BRI services, which can handle both data and voice traffic. It also supports dual 64 Kbps B (bearer) channels, as well as a 16 Kbps D (delta) channel for signalling, further increasing data communication efficiency. The unit is compatible with Cisco modular routers, making it an excellent choice for expanding network infrastructure flexibility, especially in environments that require numerous ISDN access points.
Being a motor-driven digital module, this interface is also hot-swappable, meaning it can be inserted or removed without powering down the device. This is an important feature that minimises network downtime during installation or while performing maintenance. The NM-8B-U= is fully compliant with international ISDN standards and is equipped with the necessary hardware to leverage a full range of ISDN signalling protocols.
Additionally, the Cisco Interface Module NM-8B-U= is part of the Cisco Network Modules family and integrates seamlessly into supported Cisco router platforms to enable efficient WAN connectivity. This expansion module is ideal for organisations needing scalable and flexible ISDN connectivity across multiple sites or departments.
