Ethernet Line Cards
2-Port 10-Gigabit Ethernet + 20-port 1-Gigabit Ethernet (2x10GE + 20x1GE) Combination Line Card
The 2-port 10-Gigabit Ethernet + 20-port 1-Gigabit Ethernet (2x10GE + 20x1GE) combination line card 
has two 10-Gigabit Ethernet XFP module ports and 20 Gigabit Ethernet SFP module ports. Each port 
(XFP or SFP) connects to an XAUI interface on one of the four NPUs. The 2x10GE + 20x1GE 
combination line card supports WAN PHY and OTN modes as well as the default LAN mode.
The 2x10GE + 20x1GE combination line card is available in base, extended, and low-queue versions. All 
versions are functionally equivalent, with the extended version of the line card providing typically twice 
the service scale of the base line card.
Figure 2-25 shows the block diagram for the 2x10GE + 20x1GE combination line card, and Figure 2-26 
shows the front panel connectors and indicators.
