Cabling Diagrams

Before beginning, find the appropriate cabling diagram for the topology in your installation:

When installing a cascaded system, it is extremely important to follow the sequence of procedures
Note
outlined in the section

Single Link: Inline Topology

In the inline topology, the SCE 2000 resides physically on the GBE (Gigabit Ethernet) link between the
subscribers, which are usually connected through 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, where the SCE 2000 usually connects to a router or layer 3 switch network element.

In the single link inline topology, either the first GBE link (first two ports) of the SCE 2000 or the second
GBE link (third and fourth ports) can be used, as illustrated in the diagram above. The remaining pair of
ports is unused.
Either port 1 or port 3 is used for connecting to the network element that is deployed on the subscriber
side of the SCE 2000 while port 2 or port 4 is used for connecting to the network element that is deployed
on the network side of the SCE 2000 .
Inline topology requires both Receive and Transmit fibers.

Single Link: Receive-only Topology

In this topology, an optical splitter resides physically on the GBE link that the SCE 2000 should monitor.
The optical splitter is connected to the SCE 2000 via Rx links only.
In this topology, the traffic passes through the optical splitter, which splits traffic to the SCE 2000.
