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

End-of-Life FPC Guide located at http://www.juniper.net/techpubs/.

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.
