E1000-2 Faceplate and Block Diagram
The E1000-2 Gigabit 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 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.
Each E1000-2 card supports standards-based, Layer 2 Ethernet switching between its Ethernet interfaces
and SONET interfaces on the ONS 15454. The IEEE 802.1Q VLAN tag logically isolates traffic
(typically subscribers).
Multiple E-Series Ethernet cards installed in an ONS 15454 can act together as a single switching entity
or as independent single switches supporting a variety of SONET port configurations.
You can create logical SONET ports by provisioning STS channels to the packet switch entity within the
ONS 15454. Logical ports can be created with a bandwidth granularity of STS-1. The ONS 15454
supports STS-1, STS-3c, STS-6c, or STS-12c circuit sizes.
Note
When making an STS-12c circuit, the E-Series cards must be configured as single-card EtherSwitch.
