PICs provide the physical connection to various network media types, receiving incoming
packets from the network and transmitting outgoing packets to the network. During this
process, each PIC performs framing and line-speed signaling for its 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
media type of that PIC.
PICs are hot-removable and hot-insertable. You can install up to four PICs in the slots
of each Type 1 and Type 2 FPC, and up to two PICs in the slots of each Type 3 FPC. Type
1 and Type 2 PICs have captive screws at their upper and lower corners. Type 3 PICs have
an upper ejector handle and a lower captive screw.
The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, IP Services,
and SONET/SDH interfaces. Blank PICs resemble other PICs but do not provide any
physical connection or activity. When a slot is not occupied by a PIC, you must insert a
blank PIC to fill the empty slot and ensure proper cooling of the system.
