Physical Interface Cards

Juniper Networks M-series routers and T-series platforms use PICs to connect to a wide variety of network media. PICs receive incoming packets from the network and transmit outgoing packets to the network, performing framing and line-speed signaling for their specific media type. Before transmitting outgoing data packets, the PICs encapsulate the packets received from the FPCs. Each PIC is equipped with an ASIC that performs control functions specific to the PIC's media type.

See Table 6 for a list of current PIC interfaces.

PICs install into the FPCs (on the M5 and M10 routers, into the FEB). Each FPC can accept up to four PICs. The PICs for each router are unique to that router.

See Table 7 for the number and type of PICs that are currently supported on each router.
