Physical Installation

Bump-in-the-Wire (Inline) Topology

Typically, the SCE 1000 is connected on a full duplex line between two devices (Router, BRAS, etc.). When the SCE 1000 is installed as a bump-in-the-wire, it physically resides on the data link between the subscriber side and the network side, and can both receive and transmit traffic.

A bump-in-the-wire installation is referred to as inline connection mode.

External Splitting (Receive-only) Topology

In external splitting, an external optical splitter resides physically on the GBE link between the subscriber side and the network side. In this topology, the traffic passes through the external splitter, which splits traffic to the SCE 1000. The external splitter is connected to the SCE 1000 via Rx links only. The SCE 1000, therefore, receives traffic only. It does not transmit.
