Modular Interface Cards (MICs) provide the physical connections to various network
media types. MICs receive incoming packets from the network and transmit outgoing
packets to the network. During this process, each MIC performs framing and high-speed
signaling for its media type. Before transmitting outgoing data packets through the MIC
interfaces, the router encapsulates the packets received.
On the fixed MX80 chassis, the MICs come preinstalled and cannot be replaced.
On the modular MX5, MX10, MX40, and MX80 chassis, you can install a variety of MICs
in the two front slots of the router, and the optional Multiservices MIC can be installed in
the rear slot.
