Cisco NIM-1MFT-T1 Network Interface Module

The Cisco NIM-1MFT-T1 is a one-port Network Interface Module that extends a Cisco router with a Multiflex Trunk (MFT) interface capable of handling T1 or E1 circuits, delivering both voice and data over a single trunk. This design leverages Cisco’s Multiflex Trunk architecture to allocate dedicated clear-channel voice paths while also supporting data transmission on the same module, simplifying deployment in environments that rely on legacy telephony alongside traditional data networks and enabling more flexible WAN ingress options. The module is intended for use in Cisco router ecosystems, where it plugs into a compatible chassis to provide a compact, modular interface for T1/E1 connectivity, enabling voice integration with data services and reducing the need for separate network cards for each service, which can streamline installation in branch offices or campus deployments. Key specifications and capabilities are succinct: 1 port, Multiflex Trunk support for T1 and E1 formats, and clear-channel operation for voice with accompanying data channels.
