The connections between line cards and SCBs are organized in three groups:
Switch fabric—Connects the line cards and provides for packet transport between the
line cards.
Control plane—Gigabit Ethernet links between the combined SCBs/Routing Engines

except for low-level status and commands.
Management signals—Provide low-level status diagnostic support.
