located. Specifically, it is the number of the slot in which the card is installed.
M40, M40e, M160, M320, M120, T320, T640, and T1600 routers each have eight
FPC slots that are numbered 0 through 7, from left to right as you are facing the front
of the chassis. For information about compatible FPCs and PICs, see the Hardware
Guide for your router.
The M20 router has four FPC slots that are numbered 0 through 3, from top to bottom
as you are facing the front of the chassis. The slot number is printed adjacent to each
slot.
MX Series routers support DPCs and FPCs. Each FPC occupies two DPC slots and
combinations are permitted. The MX960 router has slots that support up to 12 DPCs
or up to 6 FPCs (without redundant SCB) or 5 FPCs (with redundant SCB). The MX480
router has slots that support up to three FPCs. The MX240 router has slots that support
up to three DPCs or one FPC. FPCs use the lower DPC slot number for FPC slot

Interface Naming Overview
—Internally generated interface that is not configurable.
pime
rlsq —Container interface, numbered from 0 through 127, used to tie the primary
and secondary LSQ PICs together in high availability configurations. Any failure
of the primary PIC results in a switch to the secondary PIC and vice versa.
—Redudant interface for two MultiServices interfaces.
rms
rsp —Redundant virtual interface for the adaptive services interface.
se —Serial interface (including EIA-530, V.35, and X.21 interfaces).
—SONET/SDH interface.
so
sp —Adaptive services interface. The logical interface
an internally generated, nonconfigurable interface for router control traffic.
—STM1 interface (configured on the OC3/STM1 interfaces).
stm1
stm4 —STM4 interface (configured on the OC12/STM4 interfaces).
—STM16 interface (configured on the OC48/STM16 interfaces).
stm16
—T1 interface (including channelized DS3-to-DS1 interfaces).
t1
t3 —T3 interface (including channelized OC12-to-DS3 interfaces).
—Internally generated interface that is not configurable.
tap
umd —USB modem interface.
—Voice services interface.
vsp
vc4 —Virtually concatenated interface.
—Virtual loopback tunnel interface.
vt
