Single Cisco SCE8000 GBE Topologies

In this topology, one or two 8-port GBE SPAs are installed in the Cisco SCE8000 GBE to support a
maximum of eight full duplex GBE links. The Cisco SCE8000 GBE may be either inline, to support
both monitoring and traffic control functionality, or receive-only for traffic monitoring functionality
only.

If only one SPA module (four links) is installed, it must be installed in bay 0 of the SPA jacket card.
If two SPA modules (eight links) are installed, they must be installed in bays 0 and 1 of the SPA
jacket card.
A maximum of two SPAs is supported.
The GBE SPA ports are connected in adjacent pairs.
Even ports (0,2,4,6) are the subscriber ports and the neighboring odd ports (1,3,5,7) are the network
ports.

Inline topologies require both Receive and Transmit fibers.
Receive-only topologies use only Receive fibers.
If link continuity needs to be maintained at all times when using the inline topology, optical bypass
modules should be installed, as follows:
