Cisco Network Interface Module - Network adapter - T-1/E-1 - for Integrated Services Router 4321, 4331, 4351, 4431

The SM-X-NIM-ADPTR acts as a carrier card for the Cisco 4000 Series ISRs to carry one network interface module (NIM) to be used in the ISRs SM slot.

The SM-X-NIM-ADPTR converts the SM slot on the ISR to a NIM slot and facilitates the use of NIMs such as the T1/E1 (Voice/Data), FXO/FXS, Switching, Serial, Storage Drives, Mobility (3G/4G), or G.HDSL.
