Connecting the line ports to the network

Single Link: Inline Topology

Figure 6-1: Bump-in-the-Wire Installation

In the inline or bump-in-the-wire topology, illustrated in the diagram above, 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.

Single Link: Receive-only Topology

In this topology, an external optical splitter resides physically on the GBE link between the subscriber side and the network side. The external splitter is connected to the SCE 1000 via Rx links only.

In this topology, the traffic passes through the external splitter, which splits traffic to the SCE 1000. The SCE 1000, therefore, is in receive-only topology, having only traffic monitoring capabilities.

Note Receive-only topologies can also be implemented using a switch. Such a switch must support SPAN functionality that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.
