T640 FPC Description on page 67
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, 2, and 3 FPC, and one PIC in a Type 4 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. Type 4 PICs have an upper ejector handle and a lower ejector
handle.
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
