This guide provides an overview and description of the Physical Interface Cards (PICs)
supported by the Juniper Networks M20 Internet router. The PICs are described
alphabetically. Table 1 on page 3 lists the PICs supported by the M20 Internet router
by PIC family.
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
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 PIC and Transceiver Installation Instructions located at
http://www.juniper.net/techpubs/.
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.
The M20 router supports the Type 1 FPCs listed in “FPCs Supported”on page 5.
Table 3 on page 6 provides a PIC/FPC compatibility matrix for the current PICs
supported by the M20 router.
For a complete list of end-of-life FPCs and end-of-life Enhanced FPCs for M-series
and T-series routing platforms, see the M-series and T-series Routing Platforms

FPCs Supported
The M20 router supports the Type 1 FPCs listed in Table 2 on page 5. Inserting a combination of PICs with an aggregate
higher than the maximum throughput per FPC is supported, but constitutes oversubscription of the FPC.

PIC/FPC Compatibility
Table 3 on page 6 provides a PIC/FPC compatibility matrix for the current PICs supported by the M20 router. The table lists
the first JUNOS release in which the FPC supports the PIC. For example, JUNOS 7.2 is the first release in which the M20-FPC1-EP
supports the ATM2 OC3/STM1 IQ, 2-port PIC.
