5.6 G1K-4 Card
Note
For hardware specifications, see the
“A.7.8 G1K-4 Card Specifications” section on page A-51
.
The G1K-4 card is the functional equivalent of the earlier G1000-4 card and provides four ports of
IEEE-compliant, 1000-Mbps interfaces. Each interface supports full-duplex operation for a maximum
bandwidth of 1 Gbps or 2 Gbps bidirectional per port, and 2.5 Gbps or 5 Gbps bidirectional per card.
Each port autonegotiates for full duplex and IEEE 802.3x flow control. The G1K-4 card uses GBIC
modular receptacles for the optical interfaces. For details, see the
“5.14 Ethernet Card GBICs and SFPs”
section on page 5-33
.
Figure 5-5 shows the card faceplate and the block diagram of the card.

G1K-4 Faceplate and Block Diagram
The G1K-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 while
providing a greater degree of reliability through SONET self-healing protection services. Carrier-class
Ethernet transport is achieved by hitless (< 50 ms) performance in the event of any failures or protection
