5.6 G1000-4 Card

The G1000-4 card requires the XC10G card. The ONS 15454 use s G1000-4 cards for Gigabit Ethernet

(1000 Mbps). The G1000-4 card provides four ports of IEEE-compliant, 1000-Mbps interfaces. Eac h

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

“5.15 Ethernet Card GBICs and SFPs” section on page 5-36.

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 Ethern et

encapsulated traffic (IP and other Layer 2 or Layer 3 protocols) across a SONET ne twork. Carrier-class

Ethernet transport is achieved by hitless (< 50 ms) performance in the event of any failures or protection
