5.4 G1000-4 Card

The ONS 15454 SDH 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 STM-16 on each card.

The G1000-4 card uses GBIC modular receptacles for the optical interfaces. For details, see the “5.8 GBICs and SFPs” section on page 5-14.

The G1000-4 Gigabit Ethernet card provides high-throughput, low latency transport of Ethernet encapsulated traffic (IP and other Layer 3 protocols) across a SDH network. Carrier-class Ethernet transport is achieved by hitless (< 50 ms) performance in the event of any failures or protection switches (such as 1+1 automatic protection switching [APS], SNCP ring, or MS-SPRing. Full provisioning support is possible via Cisco Transport Controller (CTC) or Cisco Transport Manager (CTM). Each G1000-4 card performs independently of the other cards in the same shelf.
