The E100T-12 Ethernet card provides high-throughput, low-latency packet switching of Ethernet traffic
across a SONET network while providing a greater degree of reliability through SONET self-healing
protection services. This Ethernet capability enables network operators to provide multiple
10/100-Mbps access drops for high-capacity customer LAN interconnects, Internet traffic, and cable
modem traffic aggregation. It enables the efficient transport and co-existence of traditional time-division
multiplexing (TDM) traffic with packet-switched data traffic.
Each E100T-12 card supports standards-based, wire-speed, Layer 2 Ethernet switching between its
Ethernet interfaces. The IEEE 802.1Q tag logically isolates traffic (typically subscribers). IEEE 802. 1Q
also supports multiple classes of service.
5.2.1 Slot Compatibility
You can install the E100T-12 card in Slots 1 to 6 and 12 to 17. Multiple E-Series Ethernet cards installed
in an ONS 15454 can act independently or as a single Ethern et switch. You can create logical SONET
ports by provisioning synchronous transport signal (STS) channels to the packet switch entity within the
ONS 15454. Logical ports can be created with a bandwi dth granularity of STS-1. The E100T-12 supports
STS-1, STS-3c, STS-6c, and STS-12c circuit sizes.
