PICs Overview
A PIC is an interface card through which network cables carry data transmissions to and
from the network plug. A PIC installs into a Flexible PIC Concentrator (FPC).
PICs are hot-removable and hot-insertable. Removing or inserting a PIC causes a brief
interruption of forwarding performance. Each PIC has an ejector lever at the bottom of
its faceplate that allows for easy removal from the router.
Table 61 on page 236 lists some PIC characteristics for each routing platform. A PIC
performs framing and line-speed signaling for its media type.
