Cisco 3201 Fast Ethernet Switch Mobile Access Router Interface Card
Scheduled to be available in December 2002, the FESMIC is a Fast Ethernet switch mobile interface card. The
FESMIC provides four (only two on the Cisco 3220 model) 10/100 autosensing switch signals. The FESMIC is based
on PC/104-Plus Version 1.2 electrical and mechanical specification standards.
Feature Summary
• Four 10/100 autosensing switch signals
• Auto-MDIX, which automatically detects and corrects Ethernet crossed cabling, eliminating the need for
crossover cables
• Support for 802.1d standard bridging, 802.1Q trunking, and 802.1p class of service (CoS)
• Support for Layer 3 routing between distinct LANs or VLANs on the FESMIC and other LAN or VLAN routing
interfaces within the Cisco 3200 Mobile Access Router
Signal Overview
The FESMIC has four Ethernet headers (the Cisco 3220 model has only two). Each Ethernet header consists of the
following signals:
• One pair of differential signals for transmit
• One pair of differential signals for receive
One additional header provides signals for LEDs on the FESMIC.
