External Splitting (Receive-only) Topology

External Splitting (Receive-only) Topology
In external splitting, an external optical splitter resides physically on the GBE link between the
subscriber side and the network side
splitter, which splits traffic to the SCE 1000. The external splitter is connected to the SCE 1000 via Rx
links only. The SCE 1000, therefore, receives traffic only. It does not transmit.
Figure 3-2
An external splitting installation is referred to as receive-only connection mode.
Note that in an external splitting installation, the SCE 1000 has only traffic monitoring capabilities.
Receive-only topologies can also be implemented using a switch. Such a switch must support SPAN
Note
functionality that includes separation between ingress and egress traffic and multiple SPAN-ports
destinations.
