Cable the Line Ports
This module provides instructions for cabling the Gigabit Ethernet ports and for configuring Gigabit
Ethernet (GBE) interface parameters.
Note When installing an External Optical Bypass module, the SCE 1000 line ports are connected to the
module. See Appendix A in the Cisco SCE 1000 2xGBE Installation and Configuration Guide for
complete instructions.

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.
