NIM-1MFT-T1/E1 Description
The NIM-1MFT-T1/E1 is a Cisco 1-port T1/E1 Voice and WAN Network Interface Module for Cisco 4000 Series ISR and Catalyst 8300 routers. The module has one multiflex trunk port with clear-channel data, MFT packet voice and two channel groups, and voice features need a PVDM4 mounted on the NIM. The port does not support unstructured E1 (G.703) or channelized data.

Key Features
The port carries clear-channel data and MFT packet voice. Unstructured E1 (G.703) and channelized data are not supported.
The port supports two channel groups, which caps how many separate services one T1 or E1 circuit can be divided into.
Voice features need a PVDM4 fitted to the NIM with screws and standoffs, and the PVDM4 provides echo cancellation up to a 128 ms tail.
Application Scenarios
At a branch with a PBX, the module terminates one T1 or E1 trunk on a Cisco 4000 Series ISR and carries packet voice and clear-channel data over the same port.
On a Catalyst 8300 2N2S-4T2X, 2N2S-6T, 1N1S-4T2X or 1N1S-6T running IOS XE 17.3.2, the module adds a T1/E1 interface for sites that still use circuit-based voice.

NIM-1MFT-T1/E1 is the one-port multiflex trunk module, and NIM-2MFT-T1/E1 has the same clear-channel data and MFT packet voice profile on two ports, so port count alone separates them. Circuits that need unstructured E1 (G.703) or channelized data cannot use either MFT module and need NIM-1CE1T1-PRI, which also supports 24 channel groups per T1 port or 31 per E1 port against two per port on the MFT modules. Packet voice on the MFT modules requires a PVDM4 mounted on the NIM.
Ordering Checklist
- Cisco 4000 Series ISR hosts: Install the module in a Cisco 4000 Series ISR router with a free NIM slot. The T1/E1 NIM family is documented for Cisco 4000 Series ISR NIM slots and is not supported on Cisco 2900 and 3900 ISRs.
