PIC/FPC Compatibility

Table 3 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.
