Cisco 3201 Serial Mobile Access Router Interface Card
The SMIC is an asynchronous/synchronous serial mobile interface card. The SMIC supports four sets (only two sets
on the Cisco 3220 model) of Cisco 12-in-1 serial signals. The SMIC communicates with the MARC through the PCI
bus. The SMIC is based on PC/104-Plus Version 1.2 electrical and mechanical specification standards.
