The fixed Physical Interface Modules (PIMs) in J2300 Services Routers provide the physical connection to various network media types, receiving incoming packets from the network and transmitting outgoing packets to the network. The PIM is equipped with a dedicated network processor that forwards incoming data packets to the Routing Engine, and receives outgoing data packets from the Routing Engine. During this process, the PIM performs framing and line-speed signaling for its medium type.
Each PIM supported on the router has the following components:
For pinouts of PIM cable connectors, see Network Cable Specifications and Connector Pinouts. For PIM replacement instructions, see Replacing a PIM.
