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.
