Following are descriptions of a number of physical topologies that the SCE 2000 supports.
Single SCE 2000 Topologies
A single SCE 2000 supports both single GBE link and dual GBE link topologies.
Single Link: Inline Topology
Typically, the SCE 2000 is connected in a full duplex GBE link between two devices (Router,
BRAS, etc.). When the SCE 2000 is installed as an inline installation, it physically resides on the
data link between the subscribers and the network.

When configuring the SCE 2000, an inline installation is referred to as “inline” connection mode.
