E100T-G Card

The ONS 15454 SDH uses E100T-G cards for Ethernet 10 MBits/s (Mbps) and Fast

Ethernet 100 MBits/s (Mbps). Each card provides twelve switched, IEEE

802.3-compliant, 10/100BaseT Ethernet interfaces that can independently detect

(auto-sense) the speed of an attached device and automatically connect at the

appropriate speed. The ports determine whether to enable or disable ﬂow control and

Ethernet ports.

E1000-2-G Card

The ONS 15454 SDH uses the E1000-2-G cards for Gigabit Ethernet

1000 MBits/s (Mbps). Each card provides two ports of IEEE-compliant,

1000 MBits/s(Mbps) interfaces for high-capacity customer LAN interconnections.

Each interface supports full-duplex operation.

The E1000-2-G cards use GBIC modular receptacles for the optical interfaces

(Figure 8). GBICs are hot-swappable input/output devices that plug into a Gigabit

Ethernet port to link the port with the fiber-optic network. The E1000-2-G card

supports short-reach (SX) and long-reach (LX) GBICs. The SX model connects

to multimode fiber and the LX model requires single-mode fiber.

G1000-4 Card

The G-1000 is a high-capacity Ethernetcard enhanced for high-bandwidth private

line interconnects. Like the E1000-2-G card, the G1000-4 provides

IEEE-compliant, 1000 MBits/s (Mbps) ports for full-duplex operation and

requires a GBIC as its optical interface.
