M20 Internet Router PIC Guide 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 singl

FPCs Supported 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.

M20 Internet Router PIC Guide 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.
