Note For hardware specifications, see the “A.7.3 E1000-2 Card Specifications” section on page A-49.
The ONS 15454 uses E1000-2 cards for Gigabit Ethernet ( 1000 Mbps). The E1000-2 card provides two
IEEE-compliant, 1000-Mbps ports for high-capacity custome r LAN interconnections. Each port
supports full-duplex operation.
The E1000-2 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.
Figure 5-3 shows the card faceplate and a block diagram of the card.

The E1000-2 Gigabit Ethernet card provides high-throughput, l ow-latency packet switching of Ethernet
traffic across a SONET network while providing a greater degree of reliability through SONET
self-healing protection services. This enables network operators to provide multiple 1000-Mbps access
drops for high-capacity customer LAN interconnects. It enables efficient transport and co-existence of
traditional TDM traffic with packet-switched data traffic.
