    T1600 PIC Overview

    This guide provides an overview and description of the Physical Interface Cards (PICs) supported by the Juniper Networks® T1600 Core Router.

    PICs provide the physical connection to various network media types. The PICs are mounted on Flexible PIC Concentrators (FPCs), which are inserted into a slot in a T1600 router. A PIC typically occupies a single slot on an FPC. PICs receive incoming packets from the network and transmit outgoing packets to the network. During this process, each PIC performs framing and high-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 a media-specific ASIC that performs control functions tailored to the PIC's media type. For complete information about installing PICs and transceivers, see the T1600 Core Router Hardware Guide located at

    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.

    T1600 routers support the Type 1, Type 2, Type 3, and Type 4 FPCs listed in T1600 FPCs Supported . T1600 PIC/FPC Compatibility provides PIC/FPC compatibility matrixes for the current PICs for T1600 routers.

    For a complete list of end-of-life FPCs and end-of-life Enhanced FPCs for M Series and T Series routers, see the M-series and T-series Routing Platform End-of-Life FPC Guide located at
