3.10 Gigabit Ethernet Applications
The TE-2020, when equipped with one or more Gigabit Ethernet (GbE) PLMs, can provide standard
Ethernet over SONET (EoS) transport. Each GbE PLM supports two, fiber-based 1000Base-SX,
1000Base-LX, or 1000Base-ZX interfaces. The GbE PLM uses ITU-T standard Generic Framing Proce-
dure (GFP) or X.86 and virtual concatenation to map Ethernet frames from each GbE interface into a right-
sized SONET connection. It provides line-rate, point-to-point transport of all valid Ethernet frames
between two GbE interfaces. It supports all Ethernet frame types, and jumbo frames up to 10 Kilobytes
long.
This simple and efficient model allows the SONET transport network to provide standard, reliable, cost-
effective Gigabit Ethernet "private line" transport - a key component in many important Ethernet services,
such as Ethernet private line, Internet access, and Transparent LAN services. The GbE PLM also allows
GbE transport to be provisioned and managed similar to transport of other, traditional private line services.
This management includes TL-1 access and full Ethernet and SONET performance monitoring and alarm
surveillance.
This section describes key applications of the GbE PLM, the operation of the GbE PLM, and several GbE
configuration examples.
The GbE PLM provides line-rate, point-to-point transport of Ethernet frames over a SONET network. This
section illustrates how service providers may use this fundamental capability to support a variety of Ether-
net applications and services.
