5.5.1 G1K-4 Compatibility
Figure 5-4 shows the card faceplate and the block diagram of the card.
Figure 5-4 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 3 protocols) across a SDH network while providing a greater
degree of reliability through SDH self-healing protection services. Carrier-class Ethernet transport is
achieved by hitless (< 50 ms) performance in the event of any failures or protection switches (such as
1+1 APS, path protection, BLSR, or optical equipment protection) and full provisioning and
manageability, as in SDH service. Full provisioning support is possible via CTC or CTM. Each G1K-4
card performs independently of the other cards in the same shelf.
5.5.1 G1K-4 Compatibility
Software R4.0 and later identifies G1K-4 cards as G1K-4s upon physical installation. Software prior to
R4.0 identifies both G1000-4 and G1K-4 cards as G1000-4s upon physical installation.
You can install the G1K-4 card in Slots 1 to 6 and 12 to 17, for a total shelf capacity of 48 Gigabit
Ethernet ports. (The practical limit is 40 ports because at least two slots are typically populated by
optical cards such as the OC-192.)
