6 Cable the Line Ports
This chapter 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 SCE 1000 2xGBE Installation and Configuration Guide for complete instructions.
Cabling Diagrams
Before beginning, find the appropriate cabling diagram for the topology in your installation:
Single SCE 1000 topologies
Single Link: Inline Topology (on page 43)
Single Link: Receive-only Topology (on page 44)
Single Link: Inline Topology
Figure 14: 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 customers existing
network.
