Ethernet Cards
The Ethernet cards eliminate the need for external Ethernet aggregation equipment
and provide efficient transport and co-existence of traditional TDM traffic with
packet-switched data traffic. Multiple Ethernet cards installed in an ONS 15454 can
act as a single switch (EtherSwitch) supporting a variety of SONET port
configurations.
E100T-12/E100T-G Card
The ONS 15454 uses E100T-12/ E100T-G cards for Ethernet (10 Mbps) and Fast
Ethernet (100 Mbps). Each card provides twelve switched, IEEE 802.3-compliant,
10/100 Base-T Ethernet interfaces that can independently detect the speed of an
attached device (auto-sense) and automatically connect at the appropriate speed. The
ports auto-configure to operate at either half or full duplex and can determine whether
to enable or disable flow control. You can also configure Ethernet ports manually.
The E100T-G card operates with the XC, XCVT, and XC10G cross-connect cards.
The E100T-12 operates with the XC or XCVT; it is incompatible with the XC10G.
E1000-2/E1000-2-G Card
The ONS 15454 uses the E1000-2 and E1000-2-G cards for Gigabit Ethernet
(1000 Mbps).They provide two ports of IEEE-compliant, 1000 Mbps interfaces for
high-capacity customer LAN interconnections. Each interface supports full-duplex
operation.
The E1000-2-G card operates with the XC, XCVT, and XC10G cross-connect
cards. The E1000-2 operates with the XC and XCVT; it is incompatible with the
XC10G.
The E1000-2 and E1000-2-G cards use gigabit interface converter (GBIC) modular
receptacles for the optical interfaces. GBICs are hot-swappable input/output devices
that plug into a Gigabit Ethernet port to link the port with the fiber-optic network.
Cisco provides two GBIC models: one for short reach applications and one for
long-reach applications. The short reach model connects to multimode fiber and the
long reach model requires single-mode fiber.
