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.

Dual Link: Two SCE 2000s Topology
In this topology, two SCE 2000s are connected to two full duplex, FE links, providing full
redundancy through cascading the two SCE 2000s. The SCE 2000s may be either inline, to
support both monitoring and traffic control functionality, or receive-only for traffic monitoring
functionality only.
When two SCE 2000s are used, the first pair of ports (FE-1 SUB/NET) in each SCE 2000 is
connected to the links, while the second pair of ports (FE-2 SUB/NET) become the cascade ports
used for communicating between the two SCE 2000s as follows:
SCE 2000 #1
• FE-1 SUB: Link 1, Subscribers side
• FE-1 NET: Link 1, Network side
• FE-2 SUB: Cascade, connect to FE-2 NET in SCE 2000 #2
