MX240 Modular Interface Card (MIC) Description

Modular Interface Cards (MICs) install into Modular Port Concentrators (MPCs) and provide the physical
connections to various network media types. MICs allow different physical interfaces to be supported on
a single line card. You can install MICs of different media types on the same router as long as the router
supports those MICs.
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 MPCs encapsulate the packets received.
MICs are hot-removable and hot-insertable. You can install up to two MICs in the slots in each MPC.
