Flexible PIC Concentrators (FPCs) house the PICs that connect the router to network
media (for information about PICs, see "M10i PICs Description" on page 8). On the M10i
router, each FPC is built in (it cannot be removed from the chassis as on other M Series
platforms) and corresponds to a horizontal row of PIC slots. The two FPCs on the M10i
router are numbered and

PICs provide the physical connection to various network media types. PICs receive
incoming packets from the network and transmit outgoing packets to the network,
performing framing and line-speed signaling for their media type as required. PICs also
encapsulate outgoing packets received from the Compact Forwarding Engine Board
(CFEB) or Enhanced CFEB (CFEB-E) before transmitting them. The controller ASIC on
each PIC performs additional control functions specific to the PIC media type.
The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, IP Services,
and SONET/SDH interfaces. You can install PICs of different media types on the same
router as long as the router supports those PICs.
PICs are inserted into a slot in Flexible PIC Concentrators (FPCs),
are built in to the chassis. Up to eight PICs install into an M10i router, as shown in Figure
4 on page 9. Four PIC slots are located in each Flexible PIC Concentrator (FPC). The
PIC slots on the upper FPC are numbered from
The PIC slots in the lower FPC are numbered from
left. The PIC slot numbers are located above
on a PIC depends on the type of PIC.
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 M10i router has a maximum throughput of 3.2 Gbps full duplex for each FPC. Inserting
a combination of PICs with an aggregate higher than the maximum throughput is
supported, but constitutes oversubscription of the FPC.
