A Physical Interface Module (PIM) is a network interface card that is installed on a J-series Services Router, to provide physical connections to a LAN or a WAN. The PIM receives incoming packets from the network and transmits outgoing packets to the network. Each 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.
The PIMs on J-series Services Routers include network interfaces for E1, E3, T1, T3, Fast Ethernet, serial, ADSL, G.SHDSL, and ISDN media.
For information about network interfaces, see the interfaces overview and configuration information in the J-series Services Router Basic LAN and WAN Access Configuration Guide.
