The Cisco NM-2CE1B is a 2-port Channelized E1/ISDN-PRI interface module, designed for use in a variety of Cisco networking platforms. This component provides Primary Rate Interface (PRI) capabilities over the E1 standard, which is widely used in European and global telecommunications networks. With two ports, the module is capable of handling two separate E1 lines, giving users up to 60 channels of ISDN PRI connectivity. Each E1 link can be either fully channelized or fractional, meaning users can allocate channels according to their needs for voice, video, or data traffic.
The module supports digital modem signals and offers flexibility in telecommunications environments, making it suitable for a range of tasks such as WAN aggregation, PBX connectivity, and leased line replacement. The Cisco NM-2CE1B supports E1 framing standards (G.703/G.704), which are industry standards for telecommunications. Its reliable support for full-duplex communications ensures faster, uninterrupted data transfer, which is essential for mission-critical enterprise operations.
In terms of connectivity, each of the two ports supports a direct connection with either E1-multiplexers or ISDN-based routers and switches. The network module also provides built-in diagnostics capabilities, including loopback commands and alarm monitoring features. This ensures easier troubleshooting and maintenance within complex network environments. The NM-2CE1B also supports T1 signalling, further enhancing its flexibility for global telecommunications deployments.
Its compact form factor and Cisco IOS compatibility make the NM-2CE1B seamlessly integrate into existing Cisco routers without needing external hardware components, providing efficient use of both physical and network resources. Users benefit from enhanced scalability, which is ideal for growing networks.
