10.2.2 Linear Networks
Linear configurations are characterized by the use of two terminal nodes, east and west. The 32-channel
terminal nodes can be equipped with a 32MUX-O card and a 32DMX-O card, or with a 32WSS card and
a 32DMX or 32DMX-O card. The 40-channel terminal nodes can be equipped with a 40-MUX-C card
and a 40-DMX-C/40-DMX-CE card or a 40-WSS-C/40-WSS-CE card with a 40-DMX-C/40-DMX-CE
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 10-5 shows five ONS 15454 nodes in a linear
configuration with an amplified and a passive OADM node.
Figure 10-5 Linear Configuration with an OADM Node
Figure 10-6 shows five ONS 15454 nodes in a linear configuration without an OADM node. See the
“9.1.2 Terminal Node” section on page 9-5 for more information.
