MX2000 Modular Interface Card (MIC) Description

The Modular Interface Cards (MICs) install into the 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 MPC. 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. The MPCs encapsulate

the packets received before transmitting outgoing data packets through the MIC interfaces.

MICs are hot-removable and hot-insertable. You can install up to two MICs in each MPC.
