NIM-2T Description
NIM-2T is a Cisco 4400 Series ISR synchronous serial WAN network interface module that adds two 12-in-1 Smart Serial ports for branch and remote-site routers that still need serial leased-line connectivity. Cisco identifies it as a 2-port serial WAN NIM with support for V.35, RS232, X.21, RS449, RS530, and RS530A interfaces, HDLC, PPP, and Frame Relay encapsulation, up to 8 Mbps per port, Cisco IOS XE Release 3.12S or later, and a single-wide NIM form factor.

Application Scenarios
Choose NIM-2T when one Cisco ISR 4000 router must carry two synchronous serial WAN circuits without allocating a separate NIM slot for each link.
Use this module when the deployment already specifies Cisco Smart Serial cabling and each circuit needs a supported V.35, EIA/TIA-232, EIA/TIA-449, X.21, EIA/TIA-530, or EIA/TIA-530A interface.
Select NIM-2T for refresh projects that keep HDLC, PPP, or Frame Relay on synchronous serial links while moving the router platform into the Cisco 4000 Series ISR NIM architecture.

- In a NIM-2T vs NIM-1T comparison, the confirmed difference is serial connector count: NIM-2T has two Smart Serial connectors while NIM-1T has one.
- The NIM-2T vs NIM-4T difference is port density, because Cisco lists two connectors on NIM-2T and four connectors on NIM-4T with the same supported serial interfaces and 8 Mbps per-port maximum.
- For buyers comparing NIM-2T vs NIM-1T or NIM-4T, the model to choose depends on required serial circuit count, available NIM slots, and whether two ports or four ports are needed in the router BOM.
Selection Guide
1. Choose NIM-2T for two synchronous serial links
Select NIM-2T when the router bill needs two Smart Serial WAN interfaces and the target ISR 4000 platform supports the serial NIM family.
2. Use NIM-1T for a single-circuit branch
Choose NIM-1T instead when the deployment has only one serial WAN circuit and preserving the second connector is not required.
3. Move to NIM-4T for four serial circuits
Select NIM-4T when the confirmed requirement is four synchronous serial ports and Cisco platform support allows that higher-density SKU.
4. Match cable role and encapsulation before ordering
Verify DTE or DCE cable selection, the serial interface standard, clocking needs for DCE ports, and HDLC, PPP, or Frame Relay encapsulation before adding NIM-2T to the quote.
Ordering Checklist
|
Review Area |
Required Confirmation |
Procurement Risk |
|---|---|---|
|
Router slot plan |
Confirm a supported Cisco 4000 Series ISR NIM slot or compatible module-placement plan |
Avoids assigning the serial NIM to a router position outside Cisco’s documented support context |
|
Software readiness |
Check Cisco IOS XE Release 3.12S or later and IP Base feature set for 4400 Series deployments |
Keeps the hardware order aligned with the documented software requirement |
|
Smart Serial cabling |
Select the cable family for V.35, RS-232, X.21, EIA/TIA-449, EIA-530, or EIA-530A |
The cable choice determines the physical interface presented to the carrier or attached device |
|
DTE or DCE role |
Verify whether either serial port must provide DCE clocking |
DCE ports use the documented clock-rate range and should be planned before field turn-up |
|
WAN encapsulation |
Confirm HDLC, PPP, or Frame Relay for the two circuits |
Cisco documents this protocol set for the serial NIM family |
|
Service-window handling |
Plan slot power shutdown or OIR command use before module replacement |
Reduces installation risk when the router is already deployed |
