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 customer’s existing

network.
