NIM-1MFT-T1/E1 Description
NIM-1MFT-T1/E1 is a Cisco 1-port T1/E1 Voice and WAN Network Interface Module for supported Cisco 4000 ISR and Catalyst 8300 router platforms. It provides one T1/E1 MFT port, clear-channel data support, MFT packet voice support, two channel groups per port, a PVDM4 requirement for voice features, and Catalyst 8300 software baseline context at IOS XE 17.3.2 / XE SD-WAN 17.3.2 / vManage 20.3.2. The module adds Cisco-supported T1/E1 WAN or voice integration to routers that need circuit connectivity beyond Ethernet.

Application Scenarios
Use NIM-1MFT-T1/E1 when a supported router needs one T1/E1 NIM port for clear-channel data and packet voice service on the same fourth-generation module family.
This SKU fits Cisco 4000 Integrated Services Router deployments where the T1/E1 interface must be installed in a NIM slot and voice features are planned with the required PVDM4 resources.
NIM-1MFT-T1/E1 can be used in Catalyst 8300 module planning where the platform and software baseline match Cisco’s listed C8300 support table.

- In a NIM-1MFT-T1/E1 vs NIM-2MFT-T1/E1 comparison, the confirmed difference is port count: NIM-1MFT-T1/E1 is the one-port MFT module and NIM-2MFT-T1/E1 is the two-port MFT module.
- The NIM-1MFT-T1/E1 vs NIM-1CE1T1-PRI difference is service profile: NIM-1MFT-T1/E1 supports the MFT voice and clear-channel data role, while NIM-1CE1T1-PRI adds unstructured E1 and channelized data support.
- Which model to choose depends on required T1/E1 port count, whether G.703 or channelized data is required, and whether the router design includes the PVDM4 resources needed for packet voice.
Selection Guide
1. Use one-port MFT for compact voice trunks
Select NIM-1MFT-T1/E1 when the router needs a single T1/E1 MFT position with clear-channel data and packet voice support.
2. Increase MFT density only when needed
Use NIM-2MFT-T1/E1 when the design needs two T1/E1 MFT ports with the same clear-channel data and packet voice profile.
3. Move to CE1T1-PRI for channelized data
Use NIM-1CE1T1-PRI instead when the order requires unstructured E1 or channelized data support that Cisco does not list for the one-port MFT row.
4. Plan DSP resources for voice
Confirm the PVDM4 requirement when packet voice features are part of the deployment because Cisco ties voice features on these T1/E1 NIMs to onboard PVDM4 resources.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact module PID |
Confirm `NIM-1MFT-T1/E1` as the required one-port MFT module |
Prevents drift to a two-port MFT SKU or a CE1T1-PRI SKU with a different feature profile |
|
Router platform |
Match the router to Cisco 4000 ISR or Catalyst 8300 support context |
The confirmed facts are tied to Cisco NIM-slot and C8300 module support tables |
|
Voice feature plan |
Confirm whether packet voice is required and PVDM4 resources are included |
Cisco states that PVDM4 is required for voice features on these modules |
|
Channelized data need |
Confirm whether unstructured E1 or channelized data is required |
Those capabilities are listed for CE1T1-PRI rows, not the one-port MFT row |
|
Software baseline |
Check the Catalyst 8300 minimum software if the module is used on C8300 |
Cisco lists IOS XE, XE SD-WAN, and vManage minimum versions for the C8300 table |
