    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 1 lists some PIC characteristics for each routing platform. A PIC performs framing and line-speed signaling for its media type.

    Note: For TX Matrix and TX Matrix Plus routers, the PICs depend on the T640 and T1600 routers interconnected, respectively, for these routers.

    Before transmitting outgoing data packets, the PICs encapsulate packets received from the FPCs. Each PIC is equipped with an application-specific integrated circuit (ASIC) that performs control functions specific to the PIC’s media type.

    For a listing of PICs supported for each routing platform, see the appropriate router hardware guide and the router PIC guide.

    Figure 1 shows the PIC location in each router and the corresponding row and slot numbering.
