• Inline vs. Receive-only Installation, page 3-4
A single Cisco SCE8000 GBE supports a number of different topologies, depending on the number of
SPAs and the connection mode.
The number of traffic links per number of SPAs is listed in Table 3-1.
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 displays the inline topology.

When configuring the Cisco SCE8000 GBE , an inline installation is referred to as “inline” connection
mode.
