Inline vs. Receive-only Installation

Inline Topology
Typically, the Cisco SCE8000 GBE is connected in a full duplex link between two devices (Router,
BRAS, etc.). When the Cisco SCE8000 GBE is installed as an inline installation, it physically resides
on the data link between the subscribers and the network.
Figure 3-2
When configuring the Cisco SCE8000 GBE , an inline installation is referred to as "inline" connection
mode.
