9.4.2 XC Termination Mesh Node
9.4.2 XC Termination Mesh Node
The XC termination mesh node, shown in Figure 9-26, is the second mesh node type. It is used to
upgrade a non-mesh node to a mesh node or to interconnect two non-mesh nodes. The XC termination
mesh nodes contain the following cards:
• 40-WXC-C cards
• OPT-AMP-17-C cards configured in OPT-PRE mode
The XC termination mesh node is connected as follows:
• The 40-WXC-C COM-RX port is connected to the MMU EXP-A-TX port.
• The 40-WXC-C COM-TX port is connected to the MMU EXP-A-RX port.
• 40-WXC-C EXP-TX port is connected to the OPT-AMP-17-C COM-RX port.
• 40-WXC-C EXP-RX port is connected to the OPT-AMP-17-C COM-TX port.
• The 40-WXC-C EXP-TX port is connected to the mesh patch panel.
• The 40-WXC-C EXP-RX port is connected to the mesh patch panel.

9.4.3 Mesh Patch Panels and Shelf Layouts
ONS 15454 mesh topologies require the installation of a four-degree patch panel (PP-MESH-4) or
eight-degree patch panel (PP-MESH-8). If the four-degree patch panel is installed, mesh topologies of
up to four degrees can be created. If the eight-degree patch panel patch panel is installed, mesh
