Dual Link: Single SCE 2000 Topologies

In this topology, one SCE 2000 is connected to two full duplex, FE links. The SCE 2000 may be either inline, to support both monitoring and traffic control functionality, or receive-only for traffic monitoring functionality only.

When one SCE 2000 supports two links, the first pair of ports (FE-1 SUB/NET) is connected to one link, while the second pair of ports (FE-2 SUB/NET) is connected to the second link as follows;

•FE-1 SUB: Link 1, Subscriber side

•FE-1 NET: Link 1, Network side

•FE-2 SUB: Link 2, Subscriber side

•FE-2 NET: Link 2, Network side

The following diagram illustrates the connections for dual links, with a single SCE 2000 deployed for both inline and receive-only topologies.

For inline topologies, the SCE 2000 is directly connected to the two FE links, using the FE-1 and FE-2 ports as described above.

For receive-only topologies, the SCE 2000 is connected to the external switch, which 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 SCE 2000 using the FE-1 and FE-2 ports as described above.
