Single Link: Inline Topology

In the inline or bump-in-the-wire topology, illustrated in the diagram bellow, the SCE 1000 resides physically on the data link

between the subscriber side, usually either a BRAS (in DSL access), a PDSN (in wireless access), a CMTS (in the Cable access),

or a switch or router aggregator (in other topologies), and the network side, usually a router or layer 3 switch network element.

This is the inline topology, providing both traffic monitoring and control capabilities.

In this topology, all the traffic of the SCE 1000 is deployed as a transparent layer2 overlay on the customer's existing network.
