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.
