18.2.5 Linear Configurations
Linear configurations are characterized by the use of two terminal nodes (west and east). The terminal
nodes can be equipped with a 32MUX-O card and a 32DMX-O card, or a 32WSS card with a 32DMX
or 32DMX-O card. OADM or line amplifier nodes can be installed between the two terminal nodes. Only
unprotected traffic can be provisioned in a linear configuration. Figure 18-5 shows five ONS 15454
nodes in a linear configuration with an amplified and a passive OADM node.
Figure 18-5 Linear Configuration with an OADM Node
Figure 18-6 shows five ONS 15454 nodes in a linear configuration without an OADM node.
See the “17.1.2 Terminal Node” section on page 17-3 for more information.
