Chapter 6 Cabling the Line Ports and Completing the Installation

Connecting the line ports to the network

In the single link inline topology, either the first FE link (FE-1 SUB/NET) of the SCE 2000 or the second FE link (FE-2 SUB/NET) can be used, as illustrated in the diagram above. The remaining ports are unused.

The port labeled "SUB" is used for connecting to the network element that is deployed on the subscriber side of the SCE 2000, while port labeled "NET" is used for connecting to the network element that is deployed on the network side of the SCE 2000.

Single Link: Receive-only Topology

In this topology, an external switch resides physically on the FE link that the SCE 2000 should monitor. The traffic passes through the external switch, which splits traffic to the SCE 2000.

The external switch should be configured with two-port replication configurations, one for upstream and one for downstream traffic on the FE link. The replicated ports should then be connected to the appropriate SCE 2000 ports.

Note When implementing receive-only topologies with a switch, the switch must support SPAN functionality that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

Figure 6-2: Cabling Diagram for Single SCE Platform Single Link Receive-only Topology

The single link receive-only topology cabling is similar to that for single link inline, in that either the first FE link (FE-1 SUB/NET) of the SCE 2000 or the second FE link (FE-2 SUB/NET) can be used, as illustrated in the diagram above. However, in the receive-only topology, the SCE 2000 is connected to the external switch rather than being directly connected to the FE link.

The port labeled "SUB" is used for connecting to the network element that is deployed on the subscriber side of the SCE 2000 while port labeled "NET" is used for connecting to the network element that is deployed on the network side of the SCE 2000. The remaining ports are unused.

Note Ports FE-3 and FE-4 currently have no software support.
