5.6 G1000-4 Card
The G1000-4 card requires the XC10G card. The ONS 15454 uses G1000-4 cards for Gigabit Ethernet
(1000 Mbps). The G1000-4 card provides four ports of IEEE-compliant, 1000-Mbps interfaces. Each
port supports full-duplex operation for a maximum bandwidth of OC-48 on each card.
The G1000-4 card uses GBIC modular receptacles for the optical interfaces. For details, see the
“5.13 Ethernet Card GBICs and SFPs” section on page 5-31.
Note Any new features that are available as part of this software release are not enabled for this card.
Figure 5-5 shows the card faceplate and the block diagram of the card.

The G1000-4 Gigabit Ethernet card provides high-throughput, low latency transport of Ethernet
encapsulated traffic (IP and other Layer 2 or Layer 3 protocols) across a SONET network. Carrier-class
Ethernet transport is achieved by hitless (< 50 ms) performance in the event of any failures or protection
