The 10-Gigabit Ethernet IQ2 PIC for the M120, M320, and T-series routing platforms operates with Type 3 FPCs. The 10-Gigabit Ethernet IQ2 PIC supports all features of the IQ2 family PICs. Additionally, it provides one external interface running at 10 Gbps that operates in two modes:
When the external interface is running in LAN PHY mode, it bypasses the WIS sublayer to directly stream block-encoded Ethernet frames on a 10-Gigabit Ethernet serial interface. When the external interface is running in WAN PHY mode, it uses the WIS sublayer to transport 10-Gigabit Ethernet frames in an OC192c SONET payload.
Although the external interface provides a lower throughput when running in WAN PHY mode because of the extra SONET overhead, it can interoperate with SONET section or line level repeaters. This creates an advantage when the interface is used for long-distance, point-to-point 10-Gigabit Ethernet links. When the external interface is running in WAN PHY mode, some SONET options are supported. For information about SONET options supported on this interface, see Configuring SONET Options for 10-Gigabit Ethernet Interfaces.
